Chicken breast is one of the most popular and nutritious cuts of chicken, offering a rich source of protein, vitamins, and minerals. It is a lean protein, meaning it has a low fat content compared to other meats, making it an ideal choice for health-conscious individuals. A 3-ounce serving of cooked chicken breast contains approximately 26 grams of protein, 4 grams of fat, and 0 grams of carbohydrates. The high protein content in chicken breast helps build and repair muscles, making it a staple in many athletes' and bodybuilders' diets.
In addition to its high protein content, chicken breast is also rich in various vitamins and minerals, including niacin, vitamin B6, and selenium. Niacin plays a crucial role in converting food into energy, while vitamin B6 is involved in many bodily functions, such as immune function and brain development. Selenium, on the other hand, acts as an antioxidant, protecting cells from damage and supporting immune function. Chicken breast is also a good source of phosphorus, potassium, and magnesium, which are essential for maintaining healthy bones, blood pressure, and muscle function.
