The acne-fighting diet: What to avoid to eating

A good diet is not only essential for good overall health but what you eat inside can show outside on your skin. Studies have shown that apart from hormones and genetics, diet is a major factor that affects the health of your skin.

Below is some food that causes or aggravates acne:

High Glycemic Index Food

Food that breaks down quickly during digestion has a higher glycemic index (GI more than 70). These are foods that break down quickly in the body, triggering an insulin spike and raising blood sugar levels. They trigger hormonal fluctuations and inflammation—both of which encourage acne. Food like white bread should be replaced with whole-grain bread and processed cereals should be replaced natural oatmeal. Other high GI food like potato chips, french fries, and even baked potatoes (yes, even that has a GI of 85) should be avoided at all cost if you want to prevent acne from appearing.


Dairy should be your worst enemy when it comes to acne. There is an abundance of a hormone called IGF-1 in milk, which is really good for baby cows, but not for humans. In humans, it tends to make your acne grow big instead. IGF-1 is one of the several factors that cause inflammation in humans, and which eventually lead to acne. In simple terms, IGF-1 is bad for acne because it is an insulin, causing the sebaceous glands to over-stimulate and produce more sebum blocking pores. Sadly switching over to skim milk won’t help either.


Sugar aggravates acne almost the same way that dairy does. Excessive sugar causes your blood sugar level to increase and your body releases insulin. Elevated insulin levels increase both IGF-1 levels and IGF-1 bioavailability. And we know what IGF-1 does to acne. Excessive consumption of sugar also increases the inflammation in the skin. Not forgetting it also cause diabetes!

For the long-term

Eliminating certain types of food can be difficult, especially if they are your favourite food. But if no amount of medication (be it oral or topical) helped you in treating your acne, eliminating these bad food will give you result that is worth it.
