As a runner, your diet and nutrition are important not only for maintaining good health, but also to promote peak performance. Proper nutrition and hydration can make or break a workout or race, and also greatly affects how runners feel, work and think.

A balanced diet for healthy runners should include these essentials: carbohydrates, protein, fats, vitamins, and minerals. Here are some basic guidelines for a nutritious, healthy balance:

Carbohydrates - The Runner's Best Energy Source

As a runner, carbohydrates should make up about 60 - 65% of your total calorie intake. Without a doubt, carbs are the best source of energy for athletes. Research has shown that for both quick and long-lasting energy, our bodies work more efficiently with carbs than they do with proteins or fats. Whole grain pasta, steamed or boiled rice, potatoes, fruits, starchy vegetables, and whole grain bread are good carb sources.

Protein

Protein is used for some energy and to repair tissue damaged during training. In addition to being an essential nutrient, protein keeps you feeling full longer, which helps if you're trying to lose weight. Protein should make up about 15% - 20% of your daily intake. Runners, especially those running long distances, should consume .5 to .75 grams of protein per pound of body weight. Try to concentrate on protein sources that are low in fat and cholesterol such as lean meats, fish, low-fat dairy products, poultry, whole grains, and beans.

Fat

A high fat diet can quickly pack on the pounds, so try to make sure that no more than 20 - 25% of your total diet comes from fats. Stick to foods low in saturated fats and cholesterol. Foods such as nuts, oils, and cold-water fish provide essential fats called omega-3s, which are vital for good health and can help prevent certain diseases.

Most experts recommend getting about 3,000 mg of omega-3 fat a day.

Vitamins

Runners don't get energy from vitamins, but they are still an important part of their diet. Exercise may produce compounds called free radicals, which can damage cells. Vitamins C, E, and A are antioxidants and can neutralize free radicals. Getting your vitamins from whole foods is preferable to supplementation; there's no strong evidence that taking supplements improves either health or athletic performance.

Minerals

Calcium: A calcium-rich diet is essential for runners to prevent osteoporosis and stress fractures. Good sources of calcium include low-fat dairy products, calcium-fortified juices, dark leafy vegetables, beans, and eggs. Your goal should be 1,000 to 1,300 mg of calcium per day.

Iron: You need this nutrient to deliver oxygen to your cells. If you have an iron-poor diet, you'll feel weak and fatigued, especially when you run. Men should aim for 8 mg of iron a day, and women need 18 mg.

Good natural sources of iron include lean meats, leafy green vegetables, nuts, shrimp, and scallops.

Sodium and other electrolytes: Small amounts of sodium and other electrolytes are lost through sweat during exercise. Usually, electrolytes are replaced if you follow a balanced diet. But if you find yourself craving salty foods, it may be your body's way of telling you to get more sodium. Try drinking a sports drink or eating some pretzels after exercise. If you're running longer than 90 minutes, then you should need to replace some of the electrolytes you're losing through sweat by drinking sports drinks or taking in salt during your runs.
