and may even increase your risk for some diseases.
#3: Eat plant foods with their skins intact
Drop the peeler. From apples and black beans to red potatoes and zucchini, plants’ outer skins protect them from UV light, parasites, and other invaders. As a result, those skins are bursting with a wide range of phytochemicals that also protect your health. Grape skins, for example, are high in resveratrol, and onion skins contain quercetin, both of which can help lower your risk of heart disease and colon and prostate cancer and boost your immunity.
Produce skins are also rich in resistant starches and various types of fiber. These compounds promote the growth of healthy bacteria in the intestines, improve intestinal function (relieving constipation and decreasing hemorrhoid risk), and help curb appetite and aid in weight control. Studies have shown that fiber from vegetable and fruit skins (which contain both soluble and insoluble fibers) actually blocks absorption of three to four percent of total calories consumed when eaten as part of a high-fiber diet. This is why people who follow a higher-fiber diet (over 35 grams daily) that consists of mainly fruits and vegetables tend to have lower body-fat levels and smaller waist sizes than low-fiber eaters.
#4: Drink milk and eat milk products that come from animals
Whether from a cow, a goat, or even a reindeer, mammal milk (as opposed to soy milk) and other dairy products, like cheese, yogurt, and kefir, should be a part of every runner’s diet. Sure, milk supplies calcium, and calcium builds strong bones, which is great for your running. But animal milk offers much more.
Dairy supplies a runner’s hardworking muscles with an ample amount of protein to help speed recovery. But whey protein, the specific type of protein found in dairy foods, may also help strengthen the immune system. Milk products also contain stearic acid, which is thought to improve blood-cholesterol levels. Ample research also suggests that regular dairy consumption can lower your blood pressure and your risk for heart disease. And for anyone watching his or her weight, studies have shown that dieters who include dairy in their low-calorie plans lose more fat than those who simply cut calories.
Fermented dairy products, such as yogurt, cultured milk, and kefir, contain live bacteria that bolster immune-system health. These bacteria, as well as a special fat in dairy called conjugated linoleic acid (CLA), can also help alleviate constipation, improve symptoms of certain intestinal ailments, such as inflammatory bowel disease, and reduce the occurrence of yeast infections in women. And people who are lactose intolerant may see an improvement in their symptoms when they regularly consume cultured dairy products.
#5: Eat foods that come from cold water
Fish and other seafood provide a unique combination of nutrients important to runners. Most seafood is an excellent source of quality protein (you need about 50 percent more protein than your nonrunning friends) and also contains zinc, copper, and chromium—minerals that are often low in a runner’s diet. But the omega-3 fats found in fish, particularly those from cold waters, are what make seafood such an essential part of anyone’s diet.
Over the past decade, researchers have unfolded a fish story of grand proportions: People who eat fish and other seafood a few times per week have a lower risk of sudden heart attack, vascular disease, and stroke. Fish intake has also been linked to lower rates of depression. And recently, low intake of fish (and omega-3 fats) has been associated with certain behavioral conditions in children, such as attention deficit hyperactivity disorder. Anthropological scientists who study “caveman” nutrition theorize that our ancestors consumed much more omega-3 fats than we currently do and that many of our modern-day ailments, such as heart disease and Alzheimer’s, may stem from low omega-3 fat intake. Runners should also
