Adding Healthy Eating To Your Exercise Plan

1/13/15

Last week, as we helped you prepare for a healthy 2015, we discussed exercise and physical activity. We gave you pointers on how to select and set-up a personalized healthy plan of action. But healthy eating plans along with being physically active are what lead to a healthy lifestyle. Today we will look at adding healthy eating to your exercise plan.
Healthy Living
But first let’s review the three main points you need to keep in mind as you engage in any physical activity.

Include physical activity in your everyday life

• That means making it a priority, even if you have to schedule it on your calendar.
• Make it easy to do. Don’t forget that taking the stairs or walking up and down all the isles at the grocery store can be considered physical activity.
• Make it a social experience by finding an exercise buddy to help encourage you.
• Be sure it is interesting and fun. You may find it more fun if you listen to a book or music on your iPod.
• Make it an active decision to include physical activity throughout your daily routine and think of new ways to be active such as parking your car at the far end of the parking lot to make the walk to the store longer (and probably easier to find a parking space).

Try all of the four different types of exercise
We discussed endurance, strength, balance and flexibility training as your options. But there is no reason to stick with just one, think about mixing it up to reduce boredom and risk of injury while you increase your overall fitness.

Plan for breaks in your exercise plan
Life happens and there will be times, such as illness, injury or travel that will interfere with your normal physical activities.

• Don’t be too hard on yourself and don’t worry about the time you have missed.
• If you have stopped because of illness or injury, check with your doctor about when you can safely resume your regular routine.
• Remember why you started exercising.
• Contact your exercise buddy and have them help you get back on track.
• Try something new if you can’t get motivated to get back to the old routine. Be creative in thinking of new ways to exercise.
• If you are starting the same routine, start again at a comfortable level. Depending on how long you have not been exercising regularly, you may need to start at a slightly lower level than where you left off.

Healthy eating emphasizes:

• A diet of vegetables, fruits, whole grains and fat-free or low-fat dairy products.
• It can include lean meats, poultry, fish, beans, eggs and nuts.
• It is low in saturated fats, trans fats, cholesterol, sugars and added salt.
• It is a balance of the calories you get from foods and beverages vs. the physical activities you engage in to keep you at a consistent weight.

To help keep those healthy foods healthy here are some tips to keep in mind:

• Eating vegetables and fruits in a wide range of bright colors give your body a wider range of nutrients. Leaving the skins on, when possible, gives the nutrients and extra boost. Remember to wash all vegetables and fruits before eating.
• Fiber is a very important to your diet. Breakfast is a great time to enjoy whole-grained foods along with fruits.
• Cut the butter and salt by seasoning your foods with lemon juice, balsamic vinegar and herbs.
• While fresh food are much better for you, if you do use packaged foods, read the labels and chose items that are low in salt, saturated fat and trans fat.
• Use lean meat with excess fat removed and poultry with the skin removed. Do not sauté in butter or fry.
• Control your portion size to limit calorie intake. Also eat more slowly to give your system time to recognized when you are full. Here is a link to picture how large portions should be.
• Drink enough fluids to keep your body working properly. This is especially true in older adults because they don’t necessarily feel thirsty even if their body needs hydration. This liquids should not have added sugars and should be low-fat if dairy and low-sodium if broths.
• When eating out look for low-fat options, have dressings, sauces and butter served on the side so you can control how much you use.
• Select tomato-based sauce over cream-based or white sauce.
• Ask for small portions. If they are still large ask for a container to take part of it home BEFORE you start to eat.
• Ask to substitute low calorie options for sides like French fries.

Even with a well-planned diet you may think you need dietary supplements. However, combinations of supplements with any prescription or over-the-counter medicine could be harmful. Also so supplements can have unwanted or harmful effects before, during or after surgery. The best way to find out if you need any supplement is to talk with your doctor.

Hopeful this has helped you get a healthy start on 2015. The next thing to do – make an appointment with your eye doctor professional for your yearly comprehensive eye exam!

7 Healthy Eating Tips for the Holidays

12/16/14

Every year the holidays come around to tempt us with a variety of wonderful foods. It doesn’t make any difference if its Christmas or Hanukah, food is an integral part of the celebration. And the celebrations are pretty non-stop from Thanksgiving through New Year’s. Here are seven healthy eating tips for the holidays to help you handle all the delicious temptations of the season (the average person says they gain around five pounds).
healthy eating tips for the holidays
1. Eat before you go – Have a small healthy snack before you go to the party, to help control your appetite once you get there. Some great snacks include, cut up fresh vegetables, small handful of nuts (remember to make it small as they have quite a few calories, but they are healthy and filling), low-fat string cheese, etc.

2. Select wisely – When confronted with an open bar ask for club soda, tonic water or even tomato juice. Still want that glass of wine? Add some club soda to make it a wine spritzer and cut some of the calories. Once you have your drink, walk as far away from the bar as possible. Another good reason beside calories to cut down on alcohol – you will be able to drive home safely.

3. Strive to be the last in line – This works well in two ways, first being that once the food is picked over it doesn’t have the visual impact of the buffet when everything is presented in its perfection, making your mind go into overload as you try to decide what all to pile on your plate. Second, by the time you go through not everything might be available, and what’s left might not let you take too large of a helping.

4. How to use your plate – If you have more than one size plate to choose from, select the smallest one. Also know that filling your plate does not mean you have to cover every square inch with food, nor do you have see how high you can layer food. You are better off making more than one trip. On the first trip start with vegetables and salads while you scan what else is available. Then you can go back for small portions of what you think are the three best offerings.

5. Lend a helping hand – If the pull of the buffet becomes too strong, help out your hosts by pouring drinks, taking dirty dishes to the kitchen, even helping clean dishes.

6. Leave the party empty-handed – No matter how grateful your hosts are for you attending, do not take home any of the leftovers. No matter where you hide them in the refrigerator, you will still know they are there.

7. Elastic is not your friend – As you socialize and catch up with old friends you can get distracted, making it hard to watch what you eat. You are better off wearing something fitted, or at least with a regular waistband, to remind you that you might be eating too much. Belts are great as long as you don’t adjust them after getting to the party.

Just because a food is healthy, it doesn’t mean that it is low in calories. As you fill your plate, select foods that “bright and colorful.” These will generally be healthier options with a lower calorie count, such as fresh fruits and vegetables. But remember that fruits, because of their higher sugar content, will have more calories. Also the “bright and colorful” approach won’t work at the dessert table with brightly-decorated cookies, cakes and pies.

Here is a color palate to get you started:

RED – tomatoes, red peppers, kidney beans, strawberries, cranberries

ORANGE/YELLOW – pumpkin, butternut squash, yellow peppers, citrus fruit

GREEN – kale, spinach and other green leafy produce, broccoli, asparagus, apples, green peppers

BLUE/PURPLE – purple cabbage, eggplant, blueberries, plums, blackberries

Two bonus tips:

1. Shopping is stressful – Even when you are shopping you will be surrounded by food, especially at the mall where food courts and food kiosks offer a variety of “quick” snacks and meals. Plan ahead. You know what your shopping area has for you to eat. Find a healthy option that offers you good fiber and protein and plan to go there for lunch. Taking a lunch break will keep you from snacking all day and help you power through an afternoon of shopping. If you need snacks, pack something healthy in your purse.

2. Moms and baking go together – There is something about the holidays that brings out the baker in every mom. So when you go home, or even if mom arrives at your house, you will be presented with baked goods filled with love . . . and calories. Here is where avoidance won’t work, you need to rely on strategic moderation. Choose just a few samples to keep and enjoy, then either take the rest to the office, or make goodie gift bags for the mail or UPS delivery person, your manicurist, paperboy, etc. Mom will be pleased that you want to share her baking expertise.

And if you are the mom making these baked goods – try making fewer in December and spread them throughout the year. Less stress for you, and whom wouldn’t want to eat a spritz cookie in July?

Diabetes And The Potential For Diabetic Retinopathy

11/20/14

Defining Diabetes

Diabetes mellitus is a group of metabolic disorders in which a person has high blood sugar levels. It occurs either because the pancreas does not produce enough insulin, or because the body does not respond appropriately to the insulin that is produced. Insulin is the hormone that converts sugar into energy for the body. There are several forms of diabetes.

Type 1 diabetes occurs when the pancreas does not produce adequate levels of insulin. It usually develops during childhood or adolescence; however, it can also occur in adults. Those with type 1 diabetes must take insulin injections. About 10 percent of those with diabetes have type 1.

Type 2 diabetes is the most common type of diabetes, affecting about 90 percent of those with diabetes. It is caused by the combination of the body’s resistance to insulin (not using its own insulin efficiently) and the pancreas not producing enough insulin. As a result, there is an increase in the level of sugar, or glucose, in the blood.

Gestational diabetes occurs in pregnant woman who have not previously had diabetes but whose blood sugars become elevated during pregnancy. In many patients, their blood sugars will return to normal after the pregnancy is over. Placental hormones make the mother resistant to insulin, causing a buildup of blood sugars. These women are at high risk for type 2 diabetes later on in their lives.

Diabetic Retinopathy: An Overview

diabetic retinopathy
Anyone with uncontrolled diabetes is at risk for developing diabetic retinopathy. According to the National Eye Institute, between 40 to 45 percent of Americans with diabetes have some form of diabetic retinopathy, the most common eye condition associated with diabetes.

In the United States, the Centers for Disease Control and Prevention reports between 12,000 and 24,000 new cases of blindness each year due to diabetic retinopathy, making it the leading cause of vision loss among American adults, ages twenty to seventy-four. The Center also projects that by 2050, the number of Americans age forty and older with diabetic retinopathy will grow from a current 5 million individuals to about 16 million. Although these statistics are alarming, you can prevent or delay damage to your vision by controlling your diabetes, along with obtaining regular eye evaluations and treatment.

Defining Diabetic Retinopathy
Diabetic retinopathy is a disease affecting the retina, caused by elevated blood sugar levels. It usually affects both eyes and occurs when uncontrolled blood sugar levels damage the small vessels of the retina, the light-sensitive tissue in the back of your eye. The retina is responsible for processing images that make vision possible. To produce clear, distortion-free vision, the retina must lie completely flat. If the delicate retinal tissue is damaged, images that you see may be blurred or distorted.

Diabetic retinopathy is a progressive disease, and thus worsens over time. Although some effects, such as blurriness and distortions, may be mild or subtle, the long-term consequences can cause severe vision loss.

Symptoms of Diabetic Retinopathy

Because diabetic retinopathy rarely causes pain, symptoms are not always apparent in the earliest stages. In fact, damage to your retina could be occurring long before you have noticeable signs. When symptoms do occur, they’re often caused by retinopathy affecting the macula, the area at the center of the retina. Symptoms may include the following:

• blurred vision

• seeing dark spots or “floaters” (small specs in your field of vision)

• decreased night vision

• vision loss

• problems seeing colors

It’s important that you see your eye specialist immediately if you have any such symptoms. Diabetic retinopathy cannot be cured, but with careful monitoring, it can be diagnosed and treated, before your vision is impaired. The treatment is typically less invasive and more effective when diagnosed at an earlier stage, before permanent damage has occurred.

How the Retina Works

The retina is made up of specialized nerve tissue that contain microscopic receptors (called cones and rods) and other nerve cells that line the back of the eyeball.

These cells carry signals (images that we see) along the optic nerve to a special area of the brain, where they’re interpreted into what we perceive as sight. You might compare the retina to film in a camera—the film delivers the photo image that the camera captures.

There are two main areas of the retina that can be damaged by diabetic retinopathy:

• The macula, the center of the retina. The macula allows you to read and see fine details and recognize colors. At the very center of the macula is a dimple known as the fovea. It is the most sensitive portion of the macula and makes sharp vision possible.

• The peripheral retina, which is the portion of the retina that is outside the macula. It’s responsible for your side vision and also makes night vision possible.

The retina lies on a nutrient-rich flat “carpet” of vessels that nourish it with necessary oxygen and nutrients. To reach the retina, however, nutrients must pass through two buffers—a thin membrane called Bruch’s membrane and a single layer of specialized cells called the retinal pigment epithelium. Waste products are also transported away from the retina through these two membranes. Diabetic retinopathy can interfere with this constant import of necessary nutrients and export of waste products.

Risk Factors for Diabetic Retinopathy

There are many factors that can raise your risk for diabetic retinopathy. However, you’ll note that many of these risk factors can be controlled.

Duration of Diabetes and Glucose Control

The longer you’ve had poorly controlled blood glucose levels, the higher your risk for diabetic retinopathy. Most diabetic individuals develop eye problems overtime, making duration of their diabetes one of the strongest predictors that they will develop this eye disease. Research has shown that nearly all type 1 diabetics and 60 percent of type 2 diabetics develop the condition within the first two decades of their diabetes diagnosis.

The American Diabetes Association (ADA) recommends fasting glucose levels between 70 and 120 mg/dL and less than 180 mg/dL two hours after meals. They also recommend a hemoglobin A1c of 7 percent of less. Hemoglobin A1c is a protein in red blood cells that bonds with blood sugars. Since red blood cells can live from 90 to 120 days, the hemoglobin A1c stays in the blood for that length of time. Accordingly, it is effective in measuring the average blood sugars over a period of time. This test tells doctors how well your treatment plan is working. You should always know what your hemoglobin A1c values are, as they may affect the interval between your retinal examinations.

Obesity

The more fatty tissue you have, the more resistant your cells are to insulin. Obesity increases your risk for diabetes as well as other serious conditions such as heart disease. Estimates suggest that 65 percent of Americans may be overweight. Being overweight aggravates high blood pressure and cholesterol. Achieving a healthy weight is important in controlling blood sugars and diabetes related complications.

Lifestyle Choices

A sedentary lifestyle, especially if you are overweight, contributes to many diseases, including diabetes, heart disease, high blood pressure, and high cholesterol levels. On the other hand, physical exercise improves circulation, lowers blood sugars, and improves your body’s use of insulin. This results in improved blood sugar levels. This benefit of increased sensitivity to insulin continues for hours after you stop exercising.

Exercise also promotes weight loss. A sedentary lifestyle contributes to insulin resistance, and makes it more difficult to keep weight off. Even light or moderate physical activity can help lower blood sugars.

Smoking is another major risk factor for developing diabetic retinopathy. Smoking also causes diabetic retinopathy to progress faster. The nicotine in tobacco not only contributes to higher blood pressure and higher cholesterol levels, but it also impairs insulin activity. Even though quitting can be difficult, it is critical to heart health and diabetes control.
Unlike smoking, alcohol consumption doesn’t have a direct influence on diabetic retinopathy. Yet because it can affect diabetes control, drinking in excess can affect the health of your eyes. Your doctor can tell you what constitutes drinking in moderation for you.

High Cholesterol Levels

Diabetes puts you at risk for chronically high cholesterol or blood fats that promote the buildup of plaque in your arteries. Although the tiniest vessels of the retina are too small for such build-up, uncontrolled cholesterol can contribute to macular edema and the development of hard exudates, the small yellow spots or lipid deposits that may form in the macula. Both conditions are associated with a higher risk of vision loss.

Doctors advise keeping “bad” or low density cholesterol (LDLs) less than 70 mg/dL. Good cholesterol or high density lipoproteins (HDLs) should be greater than 40 mg/dL in men and 50 mg/dL in women. Both men and women should strive for triglycerides, another type of fat, at levels less than 150.

High Blood Pressure

If you have both diabetes and high blood pressure (also called hypertension), you may be at higher risk for a number of eye-related problems, including retinopathy, glaucoma and optic nerve damage. Seriously elevated blood pressure not only stresses your heart, it also raises the risk for eye problems, particularly macular edema and bleeding. Chronic hypertension combined with long-term diabetes also increases the chance that your retinopathy will be more destructive and progress more rapidly. Research has consistently shown that keeping your blood pressure below 130/80 mmHg is important in minimizing the risk of hypertension related complications.

Race/Ethnicity

Diabetic retinopathy is more common in some ethnic and racial groups than others. African Americans, Asian Americans, Hispanic/Latino Americans, American Indians and Alaskan Natives are at higher risk for type 2 diabetes than non-Hispanic whites.

African Americans and Mexicans are almost twice as likely as whites to have eye problems, according to the American Diabetes Association. Native Americans also have an increased for diabetic retinopathy. Researchers aren’t sure why some ethnic groups have higher rates of diabetes, which increase the risk for retinopathy and other problems.

Age and Gender

As mentioned earlier, the longer you have diabetes, the greater your risk for diabetic retinopathy. Not surprisingly, this complication is rare among children but common among older diabetic adults. A recent study by Prevent Blindness America and the National Eye Institute, demonstrated that older adult Americans are facing a bigger threat of all age-related eye diseases (diabetic retinopathy, age-related macular degeneration, cataracts and open angle glaucoma) today than at any other time.

Genetics

Our genetic make up has an important effect on our predisposition for many health issues such as diabetes. Scientists believe that many genes or combinations of genes either promote diabetes in certain individuals or protect them from developing it.

Scientists have yet to identify every gene involved in type 1 and type 2 diabetes, but they have shown that genetics are a factor. Research studies of identical twins, for instance, have demonstrated that if one twin has type 1 diabetes, the other twin has a 50 percent change of developing the disease. If one twin has type 2 diabetes, the other twin has a 75 percent chance of developing it.

Pregnancy

Gestational diabetes is a type of diabetes linked to pregnancy; however, diabetic retinopathy is usually not a complication in these women. However, if you’re already a diabetic and become pregnant, you are at an increased risk of developing diabetic retinopathy. This is a result of the hormonal and metabolic changes that occur during pregnancy, making the disease and its complications progress more rapidly. It is recommended that you see a retinal specialist for evaluation and monitoring.

In Summary

• Diabetic retinopathy is a serious complication of diabetes that results from high glucose levels damaging the retinal blood vessels. This can cause loss of vision.

• Between 40 and 45 percent of diabetic Americans have some form of diabetic retinopathy.

• The earliest form of the disease is called background diabetic retinopathy. With time it progresses to mild, moderate, or severe nonproliferative diabetic retinopathy.

• Without proper diagnosis and treatment of nonproliferative diabetic retinopathy, the condition can advance to proliferative diabetic retinopathy, which is a serious sight-threatening stage of the disease.

• Macular edema is due to build up of fluid and thickening of the macula and can occur with any type of diabetic retinopathy. It is the most common cause of vision loss in those with diabetes.

• The duration of your diabetes and how well blood glucose is controlled are major risk factors for the development and progression of diabetic retinopathy.

• Other risk factors that play a significant role in the development of retinopathy, include high blood pressure, high cholesterol, and smoking.

• As an individual with diabetes, you’re also at increased risk for other eye diseases, especially glaucoma, cataracts, retinal vein occlusion and optic nerve damage.

• Good blood sugar control, regular eye examination, and timely treatment are the key factors in reducing the damage to the eye and keeping your vision.

Night Blindness

10/28/14

As the number of daylight hours decrease and daylight savings time is about to end, many of us feel that the days are getting much shorter. If you suffer from night blindness, your days are shorter, because getting around or driving at night, are sometimes impossible.

Night blindness is a condition that makes it difficult for a person to see in low-light situations or at night. Some types are treatable, while others are not. You will need to consult your eye doctor to determine the underlying cause of your night blindness to determine what can or cannot be done.

Courtesy of wikipedia
There are several things that could cause night blindness:
•Cataracts
•Genetic eye disease
•Vitamin A deficiency
•Diabetes
•Aging eye
•Sunlight exposure

Here is a brief look at each.
Cataracts – This is when the lens of the eye becomes gradually becomes clouded, reducing vision. Besides reducing vision at night you may also experience halos around lights. This is a treatable condition requiring cataract surgery and replacing your clouded lens with a clear artificial lens. Your vision should improve considerably.

Genetic Eye Disease – Both retinitis pigmentosa or Usher syndrome are progressive genetic eye diseases where the rods that regulate light, and cones that control color perception and detail die. Progressive night blindness is one of the first visual symptoms of these two diseases. Currently there is no treatment for them as there is no way to treat or replace the dying rods.

Vitamin A Deficiency – While rare in the US, it can be a result of other diseases or conditions such as Crohn’s disease, celiac disease, cystic fibrosis or problems with the pancreas. Options to help with the deficiency include vitamin supplements suggested by your doctor, or increasing your intake of orange, yellow or green leafy vegetables.

Diabetes – People with diabetes are at higher risk for night vision problems because of the damage to the blood vessels and nerves in the resulting in diabetic retinopathy. Not only can it cause poor night vision, it may also take longer to see normally after coming indoors from bright light outside. There is no cure, but controlling blood sugar levels with medicine and diet can help prevent developing retinopathy or help slow the progression.

Aging Eye – As we age several things happen to our eyes. Our iris, which regulates the amount of light going into the eye, gets weaker and less responsive. This can make adapting from light to dark more difficult and slower. Our pupils shrink slightly allowing less light into the eye. The lens of the eye becomes cloudier, as explained above in cataracts, limiting the amount of light into the eye. We also have fewer rods for light perception. Aside from cataract surgery there is no treatment for age-related night blindness. However, eating a diet rich in fruits and vegetables and low in saturated fat is the best way to slow the progression. Here is more information on how the aging eye is affected.

Sunlight Exposure – If your night vision seems temporarily worse after a trip to the beach or a day on the ski slopes, it probably is. Sustained bright sunlight can impair your vision, especially if you fail to wear sunglasses or goggles.

Night blindness due to genetic conditions or aging cannot be prevented. However if you protect your eyes from extreme sunlight, eat a healthy diet, and monitor blood sugar levels if needed, you can reduce your chances for night blindness.

As we head into the holiday season, you should know that some great sources of vitamin A include sweet potatoes, butternut squash and … pumpkins!

Food for Thought . . .

6/26/14

Can dinner really be delicious medicine for our eyes?

Recent studies have shown compelling evidence that specific nutrients support eye health.* When a vitamin or mineral is given as a supplement, are there the supporting micronutrients and enzymes required for optimal utilization of that supplement by our bodies? Is a nutrient more bioavailable and/or more beneficial to our health as a foodstuff than as a supplement? Are there unintended effects from supplements that are not present when the nutrient is derived from a food source?**

Visionary Kitchen - nutrients
Despite the many thought provoking questions, I personally take supplements as I feel it is difficult to acquire the nutrients strictly through food. Dietary preferences and requirements influence our everyday food choices as well as the quality of food available at our local grocery stores. Thoughtfully designed, well-sourced supplements have been shown to enhance eye health and general well being.
Here are some key nutritional principles which should be kept in mind to maximize the nutrient availability to our eyes and bodies from the foods that we eat:

1. Bioavailability: Vitamins A, D, E and K are fat soluble; the vitamin B-complex and vitamin C are water soluble. Dietary fats aid in the transport of fat soluble vitamins. Of particular importance to eye health are the fat soluble carotenoids in the vitamin A family, lutein and zeaxanthin. Carotenoids are the red, orange and yellow pigments found in fruit and vegetables such as kale, spinach, corn, apricots and orange bell peppers. To maximize their nutritional benefit, combine foods rich in carotenoids with a healthy source of fat such as olive oil, avocados or walnuts. Egg yolk contains the most bioavailable source of lutein and zeaxanthin and is preferentially deposited in the macula.

2. Nutrient Synergy: Nutrient synergy is the interaction of two or more nutrients that work together to achieve a greater effect than a single nutrient alone could. Foods have a vast array of micronutrients. We know that spinach contains a high level of lutein; however, we don’t know precisely how all the nutrients in spinach work together to promote eye health. Epidemiological studies show people who eat spinach have a lower risk for developing Age-related Macular Degeneration (AMD). Levels of lutein and zeaxanthin in the macula can be measured and low levels are a predictor for the risk of developing AMD.

3. Growing and Feeding Practices: The growing and feeding practices of the agriculture industry affect the nutrient profile and nutrient density of our food. Grass-fed versus corn-based animal husbandry, and wild versus farm-raised fish, alters the fatty acid profile. The amount of omega-3 fatty acids found in eggs varies depending upon the chicken’s diet. Ketchup from organically grown tomatoes contains nearly 50% more lycopene than from conventionally grown tomatoes. Choose quality ingredients whenever possible.

4. Cooking Techniques: Steaming, sautéing or pureeing will break down the plant cell walls increasing the body’s access to the lutein found in dark leafy greens. Cooking tomatoes will increase the availability of lycopene. Heat, however, diminishes the amount of vitamin C present. To maximize lutein and vitamin C, consume both fresh and cooked vegetable sources. Excessive heat and lengthy cooking times diminish vitamin content (mineral content will remain intact, however).

5. Whole Foods: Whole foods have benefits such as soluble and insoluble fiber which help to regulate blood sugar. Foods high in fiber have been shown to decrease total cholesterol, triglycerides and VLDL levels. Fiber supports gut health which is integral to nutrient absorption.

6. Select Eye Nutrient Dense Foods: Studies have highlighted lutein+zeaxanthin, the omega-3 fatty acids balanced with omega-6 fatty acids, the vitamin A family, the antioxidant vitamins C and E, as well as the mineral zinc. There a number of other nutrients that play a role in eye health including B vitamins, selenium and other plant based antioxidants. Knowing the food sources of these important nutrients will help you to make better food choices for eye health.

How does this sound for dinner tonight? Grilled wild salmon on a bed of lightly sautéed spinach with caramelized onions!

Beyond Eating Green

Beyond Eating Green

Spinach and kale aren’t the only things to watch in your diet. Eating low glycemic foods may slow the development and progression of AMD. The glycemic index measures how quickly carbohydrates get glucose (sugar) into the blood stream. People with diabetes will find this familiar. High glycemic foods like potatoes, white rice, processed foods like cakes and crackers and cereal raise the blood glucose level. Low glycemic foods include vegetables and beans.

from www.crossfithoboken.com
from www.crossfithoboken.com
Several years ago researchers at Tufts University found that mice fed a low glycemic diet developed fewer and less severe age-related lesions in the retina than mice fed the higher GI diet. When lesions like this develop after age 60 in humans, they are the earliest warning sign of age-related macular degeneration. Earlier studies in humans resulted in similar observations.

*Here are some tips from Harvard University for low-glycemic eating.

1. Eat a lot of non-starchy vegetables, beans, and fruits such as apples, pears, peaches, and berries. Even tropical fruits like bananas, mangoes, and papayas tend to have a lower glycemic index than typical desserts.

2. Eat grains in the least-processed state possible: “unbroken,” such as whole-kernel bread, brown rice, and whole barley, millet, and wheat berries; or traditionally processed, such as stone-ground bread, steel-cut oats, and natural granola or muesli breakfast cereals.

3. Limit white potatoes and refined-grain products, such as white breads and white pasta, to small side dishes.

4. Limit concentrated sweets – including high-calorie foods with a low glycemic index, such as ice cream – to occasional treats. Reduce fruit juice to no more than one-half cup a day. Completely eliminate sugar-sweetened drinks.

5. Eat a healthful type of protein, such as beans, fish, or skinless chicken, at most meals.

6. Choose foods with healthful fats, such as olive oil, nuts (almonds, walnuts, pecans), and avocados, but stick to moderate amounts. Limit saturated fats from dairy and other animal products. Completely eliminate partially hydrogenated fats (trans fats), which are in fast food and many packaged foods.

7. Have three meals and one or two snacks each day, and don’t skip breakfast.

8. Eat slowly and stop when full.

Following the Rainbow

4/15/14

Last week we reviewed the rainbow of fruits and vegetables you can eat to help with eye health.  But you don’t need to limit yourself – enjoy a rainbow of nuts, whole grains and beans as well.

A reason some people avoid nuts is the number of calories found in nuts. However, a report published in the American Journal of Clinical Nutrition found that adults who incorporate nuts into their diets don’t have to limit their consumption. A review of 31 studies about eating nuts found that people who added nuts to their diets and who replaced other foods with nuts lost more weight, an average of almost one and half pounds.  Nuts have also been shown to be beneficial for stress reduction, heart health, various cancers, cholesterol, brain health and eye health.

Eating more whole grains makes your diet healthier because they are filled with nutrients including protein, fiber, B vitamins, antioxidants, and trace minerals (iron, zinc, copper, and magnesium). A diet rich in whole grains has been shown to reduce the risk of heart disease, type 2 diabetes, obesity, and some forms of cancer.

Beans, lentils and other nutritious legumes are the best sources of lean vegetarian protein. They made up of high-quality carbohydrates that are rich in fiber, zinc, vitamin B6, folate, magnesium, iron, and potassium. These protein-packed, low-fat nutrients can help with osteoporosis; improve heart-health, colon and bowel health; reduce the risks of cancer and age-related macular degeneration; control blood sugars, fight free radicals and even help with weight loss.

    Eat A Rainbow

    4/8/14

    When planning what to eat, think of a rainbow.  Eating brightly colored fruits and vegetables helps to give your body the nutrients it needs.  These same nutrients are the disease-fighting components that give fruits and vegetables their array of colors.

    by Sarah DeRemer - rainbow
    by Sarah DeRemer

    Eating a variety of colors can help –

    • Strengthen your immune system
    • Lower risk for certain cancers
    • Help ward off type 2 diabetes
    • Maintain heart heath
    • Improve memory
    • Reduce the risk for some eye diseases

     

     

    Red

    The pigments that make some foods red are known as anthocyanins and lycopene.  These are the compounds that fight free radicals and prevent oxidative damage to cells, important to preserving eye health, keeping our hearts healthy and helping to fight cancers. Heat concentrates lycopene levels so cooked tomatoes and tomatoe sauces have higher concentrations than raw fruit.

    Add red to your meals by tossing a handful of raspberries, strawberries, goji berries or pomegranate seeds into your cereal, slicing roasted beets or red bell pepper into a salad, or adding cooked red adzuki or kidney beans to a rice dish.

    Here are examples of red fruits and vegetables:

    • Red apples
    • Adzuki beans
    • Beets
    • Red cabbage
    • Cherries
    • Cranberries
    • Goji berries
    • Pink grapefruit
    • Red grapes

    • Red peppers
    • Pomegranates
    • Red potatoes
    • Radishes
    • Raspberries
    • Rhubarb
    • Strawberries
    • Tomatoes
    • Watermelon

    For a recipe filled with lycopene, try a zesty Orange and Tomato Salsa, one of three salsa crudas using brightly colored fruits.

    Orange & Yellow

    Orange fruits and vegetables contain beta-carotene, a powerful antioxidant that promotes eye health, can delay cognitive aging and protect the skin from sun damage.  Beta-carotene also converts to vitamin A, which is important for night vision and the health of your immune system.  Orange foods also contain vitamin C, another antioxidant that boost the immune system, but also protects against cardiovascular disease.  Yellow fruits and vegetables contain lutein, another nutrient important for healthy vision.

    Some of the sources you can enjoy include:

    • Sweet potatoes
    • Carrots
    • Pumpkin
    • Apricots
    • Cantaloupes
    • Summer squash
    • Citrus fruit

    • Papayas
    • Peaches and nectarines
    • Sweet corn
    • Yellow peppers
    • Mangoes
    • Pineapple
    • Yellow tomatoes

    To incorporate more orange/yellow foods into your diet, replace French fries with crisp, baked sweet potato slices, keep dried apricots, pineapple or mangoes handy for a ready-to-eat snack or add sweet potatoes to black beans or chili for a color and texture boost.

    To get your day off to a great start, try an Apricot-Orange Breakfast Smoothie.

    Green

    Green fruits and vegetables are colored by natural plant pigment called “chlorophyll” and are rich in lutein and zeaxanthin,  pigments that may help your eyes filter damaging light rays, thus protecting against macular degeneration, the leading cause of vision loss in people over 65. Green fruits and vegetables are also a good source of vitamins C & K, fiber, folate and magnesium which contain anti-cancer properties as well as helping promote strong bones and teeth.

    Some examples of the green group include:

    • Green apples
    • Artichokes
    • Asparagus
    • Avocados
    • Green beans
    • Broccoli
    • Brussels sprouts
    • Green cabbage
    • Cucumbers
    • Green grapes
    • Celery

    • Green Pepper
    • Honeydew melon
    • Kiwi
    • Kale
    • Lettuce
    • Limes
    • Green onions
    • Peas
    • Green pepper
    • Spinach
    • Zucchini

    A delicious way to eat your greens is a Summer-time Asparagus, Strawberry and Spinach Salad.

    Blue & Purple

    Blue and purple fruits and vegetables are rich anthocyanins, lutein, zeaxanthin, resveratrol and vitamin C.  These nutrents help protect cells and heal your body. Research suggests they play active roles in promoting eye and heart health, preventing premature aging, reducing inflammation, decreasing cancer cell growth and improving memory.

    Foods such as blueberries, figs, eggplants, plums and grapes get their gorgeous hue from the phytochemical anthocyanin (also found in red foods). Anthocyanins act as powerful antioxidants that protect cells from damage and may help reduce the risk of heart disease, stroke and cancer. Studies have even shown that eating more blueberries is linked with improved memory function and healthy aging.

    Be sure to help yourself to plenty of blue/purple foods, such as

    • Blackberries
    • Blueberries
    • Eggplant
    • Figs
    • Juneberries
    • Plums

    • Prunes
    • Purple grapes
    • Raisins
    • Purple cabbage
    • Bilberries
    • Acai berries

    Here is another easy yet eye-healthy dish from our Eye Cook webpage, Eggplant and Tomato Pasta .

    White

    White fruits and vegetables are colored by pigments called anthoxanthins, which may help lower cholesterol and blood pressure.  Onions also have the flavonoid quercetin, known for its anti-inflammatory properties and cardiovascular health benefits.   As we know, being heart-healthy is also being eye-healthy.

    Some members of the white group, such as bananas and potatoes, are also a good source of potassium, while the hard-shelled coconut is considered a “superfood” because its natural water is loaded with vitamins, minerals, and electrolytes, while the raw coconut meat (flesh), which is found around the inside of a coconut shell contains high levels of lauric acid, for helping reduce cholesterol and promoting brain health.
    Some examples of the white group include:

    • Bananas
    • Cauliflower
    • Coconut
    • Garlic
    • Ginger
    • Jicama
    • Mushrooms

    • Onions
    • Parsnips
    • Pears
    • Potatoes
    • Radishes
    • Shallots
    • Turnips

    This recipe for Dark Chocolate Fondue, not only has cream of coconut, but is wonderful when dipping bananas!
