Currently, there has not been enough research to prove a direct link between diet and acne. However, on an anecdotal and observational level (meaning that it has been noticed but not confirmed in rigorous scientific studies and trials), it does appear that diet could be related to acne outbreaks.
It is thought that foods that lead to higher blood sugar levels, such as foods that are rich in sugar, carbohydrates and dairy, result in an increase of the hormone IGF-1 in the body, which in turn results in an increase in the hormones testosterone and DHT.
As you may have seen on our DNA and hormones page, testosterone and DHT bind with receptors in the skin and lead to your sebaceous glands expanding and producing more oil – the result being more acne-causing blockages forming in your hair follicles.
There is also some concern around the hormones that are present in dairy products and their effect on acne. However, this link is also yet to be proved.
If you have noticed that your acne gets worse after consuming a certain type of food or drink then it may be playing a part.
