Strawberries are a superfood with some of the highest antioxidant values of any fruit. They are low in calories and fats while being rich in health-promoting vitamins, minerals, phytonutrients and fiber. With high levels of vitamin C, strawberries help boost the immune system and defend against harmful free radicals and oxidative stress. Strawberries are also rich in B-complex vitamins like B-6, riboflavin, niacin, pantothenic acid and folic acid which help the body metabolize carbohydrates, fats, and protein. They also contain good amounts of minerals like manganese (helps maintain healthy eyes), potassium (helps with controlling heart rate and blood pressure), iron, copper (required for producing red blood cells), and iodine (important for thyroid function).
