Berries are rich in antioxidants, which are mainly found in plant foods and help prevent cancer and heart disease. It is worth mentioning that the nutrition of frozen fruits is not much worse than that of fresh fruits, because they are frozen when the freshness of fruits is the highest.
2. beans

Oat is not only a nutritious whole grain food, but also contains a special dietary fiber, which helps to lower cholesterol. If you don't like oatmeal, popcorn is also a good choice, but you must not add any cream and salt.
