Benefits of B Vitamins
Chicken breast is an excellent source of B vitamins which provide many health benefits for your body. With a niacin content of 14 milligrams (mg), one 4-oz serving supplies 100 percent of the daily recommendation for adult women and 90 percent RDA for men, according to the recommendations on MedlinePlus.
Niacin provides your body with energy and aids in nerve function and your digestive system. Grilled chicken also is a rich source of vitamin B-6, with 1.3 mg, providing 100 percent RDA. Vitamin B-6 is essential for formation of red blood cells and helps keep skin healthy, says Merck Manual. Other B vitamins contributing to grilled chicken breast nutrition include thiamin, riboflavin and vitamin B-12.
An Abundance of Minerals
Grilled chicken breast contains 6 mg of calcium to help your muscles contract and your blood to clot. Calcium works with phosphorus in chicken —292 mg per 4-oz — to help build strong bones and teeth.
One serving of grilled chicken breast provides .5 mg of iron, a component of hemoglobin. Along with the 443 mg of potassium in chicken, it provides the ability for blood to carry oxygen and conduct electrical charges between cells to keep your organs functioning properly, says the National Institutes of Health. Chicken breast also contains zinc, which supports your immune system.
High Cholesterol Content
Grilled chicken breast contains a significant amount of cholesterol with 118 mg per 4 oz. You need cholesterol to help with digestion, and make hormones and vitamin D. Your body makes all the cholesterol it needs so excess from food often takes up residence in your arteries, building up and eventually blocking blood flow.
According to the American Heart Association, although there are no specific recommended limits for the amount of cholesterol you consume from food, it's still important to keep your body's cholesterol levels in a healthy range.
