Focus on These Foods to Help Protect Your Eyes

August 3, 2011

Did you know that age-related macular degeneration, aka AMD, is the leading cause of vision loss as you get older? Do you have friends or family members who are losing their vision?

Perhaps they’ve been diagnosed with AMD, which affects the central vision and results in significant vision loss or even blindness. Spots, referred to as blind spots, cloud this central vision making it very difficult to see faces clearly, read and drive. And don’t miss this. If you have a family history of AMD, are female or white…all three increase your risk.

What if you can add certain foods to your diet NOW to help prevent AMD down the road? Data from the Age-Related Eye Disease Study (known as AREDS) reported in the May 2009 issue of the journal Ophthalmology found that participants whose diets were high in certain nutrients including vitamin E and C, zinc, lutein, zeaxanthin, and omega-3 fats had the lowest risks of age-related macular degeneration.

Other studies suggest that a diet consisting of more low-glycemic foods (vegetables, fruits, beans, lentils and whole grains as examples) and less high glycemic foods such as candy, desserts, and sweetened drinks results in a lower risk for AMD.

In case you’re wondering how refined or processed foods, which are typically high on the glycemic index affect vision, here is what scientists currently believe. High-GI foods cause a rapid increase and decline in blood glucose levels as opposed to low-GI foods that raise blood glucose more slowly.

The rapid rise in blood glucose may damage the macula or part of the retina, which provides detailed central vision. The good news is that the certain nutrients just mentioned above seem to help protect your eyes from AMD.

Consider making these foods a staple in your diet.

Citrus fruits, kiwi, berries, potatoes, tomatoes: Vitamin C
Nuts (walnuts have fats that convert to omega-3s in the body): Zinc, Vitamin E and healthy fats
Red meat, poultry, beans, nuts, seafood (such as crab and lobster), whole grains, fortified breakfast cereals, and dairy products: zinc
Dark green leafy veggies such as broccoli, spinach, kale plus yellow foods such as corn and egg yolks: carotenoids: lutein
and zeaxanthin.
Cold-water fish like salmon or canned tuna: omega-3 fats

The good news is that all the foods mentioned above are not only beneficial for eye health but for your total body health.

Nutrition Strategies to Maximize Strength Training

Is strength training part of your regular workout routine? Or, have you decided it’s time to include it? Strength training or weight training can improve quality of life and overall health by reducing both blood glucose levels and body fat. It improves strength as muscle mass increases and is maintained.

Strategy # 1: Eat 1-2 hours before your workout and 30 minutes after.

According to an article in Today’s Dietitian, people say they don’t want to eat before or after a workout or they will blow the benefits. However, think about it this way.

When you have a meal or snack before a strength training session, your energy level increases and ultimately can result in additional calories burned…in other words, you don’t poop out as quickly.

Most sports nutritionist suggest a meal or snack two hours before a workout but at least one hour if the snack is smaller in size. According to a second article in Today’s Dietitian, a pre-strength training meal or snack should be high in carbohydrates, moderate in protein, and low in fat and fiber in order for the stomach to empty quickly such as a bagel and fresh fruit.

Don’t forget that nutrition post workout is part of the smart strategy. Eat a meal or snack consisting of carbs and protein within 30 minutes to speed glycogen recovery and to help repair muscle microtears that may occur during lifting.

Storage rates for glycogen are fastest the first hour after exercise. Remember that carbohydrate, one of the three energy nutrients along with protein and fat that supply calories, fuels the brain and body and most easily converts to energy or glucose. Stored glucose is called glycogen.

Strategy # 2: Increase protein for muscle hypertrophy and strength gains.

Remember that your intake varies depending on your routine but in terms of protein needs for the day, sports nutritionists Janice Dada and Dr. Jenna Bell suggest 1.2 to 1.7 grams protein/kilogram body weight for strength training.

The range for protein in the daily diet has been 5-35% of total daily calories. Now the suggestion is to reach the higher end of that range….20-35% of total calories from protein, especially when you weight train.

Muscle hypertrophy and strength gains also result from repeated sets of higher weights and less repetitions plus the right nutrition. Remember that if you are just starting out and are a strength-training novice, it’s important to start slowly and build muscle endurance with lighter weights or resistance before you progress to heavier weights and strength gains.
