Actually it's used as food additive, which make food crispy and tasty, overall help to improve texture, but if anyone have it in regular basis, it can affects function of vital organs, thus effect on metabolism.

Include good quality protein, more fruits and vegetables in your daily life and drink 3 litre water per day. Increase your activity level and have sound sleep about 6-7 hours.
