                    Gold Medal Nutrition: Eat Like an Olympian.

To make it to the 2012 Olympics, athletes not only train their bodies and their minds to perfection, they must hone in on their nutrition. They know that what they eat can make a difference in Olympic gold. Training and competing in the Olympics involves a tremendous amount of hard work, dedication and perseverance. Eating a healthy diet sufficient  in nutrients and calories to fuel training is the key component and may just be the deciding factor in that tenth of a second that distinguishes a gold medal from silver. These athletes know firsthand how to eat and drink for optimal performance and recovery.

Olympians Eat Breakfast Daily.
Olympians consume their first meal approximately 30 minutes after waking up. Our bodies become insulin sensitive after eating breakfast. Insulin sensitivity refers to how well the body responds to the hormone insulin. When you eat most of your calories earlier in the day, the total caloric intake throughout the day actually decreases. Starting the day with protein is a good choice. When consuming lean protein in the morning choose omega-3 rich eggs or egg whites; low-fat, organic dairy; lean and clean breakfast meats; as well as the high protein, whole grains like steel cut oatmeal or quinoa.

Olympians Eat Organic.
Foods which are not organic may be toxic and pose severe health risks to people as well as hinder athletic performance. Avoid the most contaminated fruits and vegetables by purchasing organic versions. “The Dirty Dozen” list of fruits and vegetables was put together by the Environmental Working Group, this list includes apples, celery, bell peppers, peaches, strawberries, nectarines, grapes, spinach, lettuce, cucumber, blueberries and potatoes—some of the most contaminated fruits and vegetables.

Olympians Eat Small, Frequent Meals.
The Olympic season is considered peak season for athletes. They should fuel often, eating every four hours. By keeping a regular meal schedule athletes can prevent fatigue and reduce injury risk. During competition the most rapid use of fuel, regardless of intensity occurs during the first 20 to 30 minutes. The goal of athlete’s during competition is to provide macronutrients and calories to sustain the activity. Athletes need proper nutrition to prevent glycogen depletion, enhance their immune function, reduce muscle damage, and speed

Olympians Hydrate Often.
When entering competition fully hydrated, chances are athletes will be able to perform better. Fluid requirements vary from person to person, so the best way to stay adequately hydrated is to stick to a schedule. Different from Olympians, most of us only require approximately 11 to 15 cups of water daily, according to the Institute of Medicine. Choose to drink filtered water were many of the dangerous contaminants have been removed.

Olympians Love Power Foods.
Dana Torres, swimming: Power food choice: raw almonds Almonds are the best high fat, anti-inflammatory food! It’s not often nutritionists recommend high-fat foods, but the quality fat found in almonds is super supportive for athletes especially during recovery. One serving of almonds contains six grams of protein, six grams of carbohydrates, and more than 20 flavonoids. These antioxidants prevent free-radical damage resulting from extreme training sessions. Manganese and copper are two minerals found in almonds. Both are needed to maintain the metabolic processes and support stamina. Almonds are also high in magnesium. When an athlete has enough magnesium in their system, their vessels relax, which improves blood and oxygen flow throughout the body.
Ashton Eaton, decathlon: Power food choice: Light tuna packed in water.Tuna is an excellent source of protein. Tuna is rich in magnesium, potassium, B vitamins and omega-3 essential fatty acids. By consuming a healthy, lean protein after a strenuous workout recovery time is enhanced.
Carli Lloyd, soccer:Power food choice: edamame. Edamame is considered one of the best plant proteins, similar in quality to eggs and cow’s milk. A unique protein in soy called, peptides, is known to provide extreme health benefits, including improved blood pressure, controlled blood sugar and improved immune function, all which are necessary in the world of extreme sport. While soy foods are still linked to controversy, stick with organic, whole food forms. Choose fermented versions like tempeh, fermented tofu, and soy miso which include immune boosting probiotics.
Tamika Catchings, basketball: Power food choice: grilled chicken.Chicken is so versatile! It is a great source of protein. Approximately 67 percent of our daily protein needs are found in just 4 ounces. Skinless chicken breast is an athlete favorite. Athletes are encouraged to eat lower fat options. Athletes are very hard on their bodies, so the lean protein found in chicken breasts may actually help prevent bone loss. Chicken is very rich in B6 and niacin. These B vitamins are necessary in the conversion of proteins, fats, and carbohydrates into usable energy.
Heather O’Reilly, soccer: Power food choice: Greek yogurt .Foods rich in probiotics have been shown to enhance recovery from fatigue and help maintain a healthy immune system. The International Journal of Obesity, recently published information showing that “adding one or two servings of yogurt to your daily diet can help you maximize loss of fat and minimize loss of muscle.” For athletes, dairy may enhance gains in lean mass, strength output, as well as reduction in body fat levels.

Sample Olympian Diet.
Approximately 60 percent of an athlete's diet should steam from carbohydrates with a mix of vegetables, fruits, whole grains and small amounts of low fat, organic dairy. About 30 percent of an athlete's diet should come from lean proteins, fish, poultry, lean meats, beans, and low fat, organic dairy. Another 10 percent of an athlete's diet should come from quality fats, olive and canola oils, nuts and nut butters, seeds and avocados. A smart nutrition goal for any athlete would be to enjoy a nutrient rich, mostly plant-based diet. Always fuel before, possibly during and after exercise. Balance energy by eating small, frequent meals throughout the day and be sure to hydrate adequately with water, herbal teas and natural juices. Good nutrition will always enhance performance. Never let poor nutrition be a limiting factor.

                                                          Summer's Best Superfoods
These foods not only help you stay slim; they can cure summer's bummers. Even bug bites!
Strawberries: Block Sunburn
They have ellagic acid, a compound that protects against UV radiation, an animal study in Experimental Dermatology finds. This acid works by reducing the release of molecules linked to inflammation—which can lead to that oh-so-attractive lobster look. Plus, the acid preserves skin smoothing collagen. Adios, wrinkles.
Leafy Greens: Double as ShadesWhen eyes are exposed to excess sunlight over time, it can trigger cataracts and macular degeneration. Before you tune out, know that these "granny problems" can start to develop as early as your 20s and 30s. Load up now on dark greens (spinach, kale) for their lutein and zeaxanthin, compounds that can filter out damaging blue-light rays.
Cherry Juice: Gives You Staying PowerIt's outdoor-sports time, but post-exercise soreness can cramp your summer-partying style. Stay loose with this juice. Runners who drank it pre-race had 67 percent less pain afterward than nonsippers, the Journal of the International Society of Sports Nutrition indicates. Tart cherries pack anthocyanins, antioxidants that reduce inflammation.
Green Tea: Shrinks Your Stomach
Meet your bikini-body secret weapon. The brew's antioxidants may help block fat absorption, data from Penn State in University Park notes. Mice eating green tea extract put on pounds more slowly than tea-free mice. About 2 cups a day in hot, chilled or ice-pop form may help us slim down, too.
Garlic: Kicks Ticks
People who popped garlic pills (1,200 milligrams, the equivalent of two cloves a day) got fewer tick bites than placebo takers, The Journal of the American Medical Association shows. Garlic may change the way you taste, turning off the bloodsuckers. Eat the bulb, or try supplements if the smell is too much for you.
