Dairy products contain hormonal and bioactive components that can result in pimples, excess oil, and acne. Consuming dairy products or even protein derived from whey can increase levels of insulin-like growth factors. Numerous studies have now shown a connection between increased dairy consumption and an increase in acne lesions. Acne may develop as a result of testosterone-related components found in milk stimulating the skin’s oil glands.
If you’re thinking about giving up dairy completely to get better skin, be aware that not all products are created equally.
According to a study, there is some correlation between general milk consumption and acne, especially for those who consume large amounts of it. Skimmed milk had the greatest (negative) effect on the skin, interestingly, while whole, semi-skimmed, low-fat, and skimmed milk all had differing interactions with acne.
On the other hand, it has been discovered that consumption of fermented dairy products, such as yoghurt and cheese, does not raise the risk of developing acne.
Additionally, the consumption of fermented dairy products like kefir and live yoghurt has been linked to improved digestion, weight management, and heart and bone health.
