Although the cause of the pills is the change of hormones in the human body, but there are some foods have a strong and negative impact on the health of the skin and the production of hormones and thus aggravate the grain. Therefore, you should increase the amount of vitamins and minerals in your diet to help reduce the grain, but it is also necessary to consult a dermatologist to assess the situation better. Here are some tips for a diet that works to reduce the appearance of pills and eliminate excess weight:

Eating fiber daily helps to keep the colon clean, and toxins can be removed from the body before it reaches the skin. (Examples: whole grains such as Nestlé Fitness, fresh fruit / vegetables). Foods that contain high fiber take longer to digest and thus keep your blood sugar from rising very quickly and reduce the amount of insulin hormone.
Eat a low-fat diet because high-fat foods work to raise hormone levels in the body and thus cause blemishes on the skin.
Avoid fried foods.
Limit salt intake and avoid high salty snacks such as potato chips, meat, canned foods, and salted popcorn.
Avoid soft drinks and sweets to contain a high percentage of sugar that works to raise the level of insulin in the blood.
Replace the coffee with DECAF (3-4 cups a day)
Do not forget to eat regular meals, start your day with a good breakfast that contains protein and starch made from whole grains such as Nestlé Fitness breakfast cereals.
Exercise 3 times a week
Drink at least ^ glasses of water a day.
