Advantages of eating sweets is that we are obtaining glucose which is a form of energy to make us active but we should only eat 2 or maximum 3 sweets no more than that.. Disadvantages are that eating a lot of sweets is not good for our health and it is a junk food which can cause our teeth to become yellow,loosen our gums, and makes us fat. So we should avoid a lot of sweets or sweet food in order to increase our life span and become more healthier.such small things can make a large difference and god forbid we can never tell when it will turn into a big disease so please avoid eating too much sweets. Thank you.
