1. RED MEAT
Salt, especially iodized salt, is not good for the skin because it may lead to the swelling of the tissues and the aggravation of acne. This will make you look puffy and unhealthy.
3. SUGAR
Sugar is the most aging food that you consume and it makes your immune system weak. It speeds up the production of wrinkles and makes your skin lackluster due to the damage it caused in your body’s collagen and elastin.
4. FRIED FOODS
Unhealthy fats from fried foods contain free radicals that can clog pores. To include healthy fats in your diet, choose instead avocado and olive oils.
5. FOODS WITH HIGH GLYCEMIC INDEX
When you eat foods with a high glycemic index, your body experiences an increase of glucose and insulin levels. For this reason, these foods are linked to acne. Always remember that a body with a low glycemic diet has 50% fewer accounts of acne.
6. ALCOHOL
Caffeine also severely dehydrates the body as it is a diuretic. This means that it can dry out your skin and increase your production of cortisol. The more cortisol; the faster your aging process!
8. PROCESSED SNACK FOODS
Processed foods are bad for the health and the skin. The further grains are processed and lose their original state the less they retain their natural nutrients and goodness. Processed foods are often loaded with sugar and sodium. Opt for more healthy snacks such as fruits and nuts.
9. ARTIFICIAL SWEETENERS AND COLORS
Artificial colors and sweeteners have no nutritional value. They also cause irritation in the body.
These artificial products often create inflammation and histamine reactions. Source
