Why is Milk Bad for Your Acne? Have you heard about this yet?
If you drink milk, eat cheese, ice cream, or any other kind of dairy, and you have acne, this blog post could be the most important thing you read all week.
Milk causes acne because…There is abundance of a hormone called IGF-1 in milk, which is really good for baby cows, but not for you. IGF-1 is a growth hormone. It makes baby cows grow up big and strong, but in humans, it tends to make your acne grow big instead. IGF-1 is one of several factors that cause inflammation in humans, and which eventually lead to acne (and the ugly redness and swelling that makes acne so annoying). Milk and dairy products cause an insulin spike in humans that cause the liver to produce even more IGF-1, leading to even more acne. Dairy causes your skin to produce excess sebum (oil), leading to – you guessed it! – more clogged pores, more acne, and a breeding ground for P. acnes bacteria, which feed on your sebum and spew out inflammatory by-products.
Dairy glues together dead skin cells inside your pores, so they can’t exit naturally, leading to clogged pores (and thus more acne). The milk and acne effect is well documented in the literature. In the last decade or so, a number of studies have found a strong link between the consumption of milk and increased occurrence of acne. For example, one such study found that teenage boys who drank milk broke out more often, and more severely, than those who didn’t drink milk. At least five other studies have confirmed that, in general, the more milk you drink, the worse acne you’ll get.
