Avocado - 5 healthy salad ingredients - Women's Health & Fitness

5. AVOCADO

WHY: Some nutritionists recommend eating an avocado every day. High in oleic acid, avocados guard against breast and oral cancers while maintaining healthy eyesight. According to some studies, avocados can lower cholesterol by up to 17%. Best of all, the high antioxidant levels protect against free radicals that cause aging. If 322 calories per avocado is unmanageable, try eating one-half fruit instead.
