Who knew that a holiday that included pumpkin pie, turkey stuffing and cranberry sauce could be good for your health? The fall harvest, also called Thanksgiving, is celebrated on the second Monday of October. This year, it falls on Oct. 10. It’s not the food, however, that is good for your health, but the act of giving thanks. Studies have shown that having an attitude of gratitude can improve our psychological, emotional and physical well-being.
