Vitamin C , fiber and Carbohydrates!

Asthma

Vitamin C, present in fruits, is a powerful antioxidant and anti-inflammatory agent. Its anti-inflammatory activity may decrease the incidence of asthma symptoms. A large preliminary study has shown that young children with asthma experience significantly less wheezing if they eat a diet high in fruits rich in vitamin C.

Atherosclerosis

A diet high in fiber prevents coronary heart disease. Eating fruits high in the soluble fiber pectin has also been linked with reduced cholesterol levels, which protects against atherosclerosis.

Athletic performance

Carbohydrates are the most efficient fuel for energy production and can also be stored as glycogen in muscle and liver, functioning as a readily available energy source for prolonged, strenuous exercise. For these reasons, carbohydrates may be the most important nutrient for sports performance. Depending on training intensity and duration, athletes require up to 4.5 grams of carbohydrates per day per pound of body weight or 60–70% of total dietary calories from carbohydrates, whichever is greater. Emphasizing intake of fruits and other high-quality carbohydrates while reducing intake of fatty foods may be beneficial for athletic performance.

Yep. I have read how your fiber intake requirements go way up on high protein diets too. Colon cancer sucks ass (excuse the pun) too.
