Switch to Superfood: A superfood is something that packs in maximum nutrition and provides several nutrients to the body at one time. Says nutritionist Avni Kaul, “Superfoods can give your diet a healthy boost, while reducing your risk of heart disease, memory loss, and other health problems. These foods pack a big nutritional punch. They are good sources of vitamins, minerals, fiber, and other nutrients. For example, dark green leafy vegetables are an excellent source of nutrients including folate, zinc, calcium, iron, magnesium, vitamin C and fiber.”
