Dates contain many vitamins, minerals, and antioxidants that provide health benefits. However, dates also contain a high amount of natural sugars and have a high glycemic index, which can cause blood sugar levels to spike. While dates can be a healthy substitute for sweets if consumed in moderation, their high glycemic properties are associated with potential weight gain. Dates are best consumed in small portions and as part of an overall healthy diet low in refined carbs and sugars.
