Skinless poultry offers lean protein, which can help you maintain a healthy weight and increase your lean muscle mass. Egg whites are also a terrific source of high-quality protein. Eating egg whites and skinless poultry can also help keep your blood sugars in check, which lowers your risk of type 2 diabetes and helps to stabilize your mood. Skinless poultry is a good source of B vitamins too. Vitamin B6, in particular, protects against age-related memory decline and maintains healthy hair. This vitamin also helps create dopamine, a mood neurotransmitter that may reduce PMS symptoms. Selenium in eggs, chicken, and turkey is an antioxidant that maintains healthy skin and joints.
