What is the problem with Dairy?
If you suffer from acne, you may want to limit your dairy consumption, more specifically your milk intake. Results from studies have shown that cow’s milk increased both the number of people who got acne and its severity.
Even Nestle, the world's largest producer of milk, explains in a 2011 research paper published in Nestle's Nutritional Workshop Series how milk can cause acne.
What is in milk that causes acne?
Milk is full of anabolic hormones, hormones that promote growth. Research indicates that there are over 60 hormones in a glass of milk. Most of the hormones are andorgens, such as testosterone, dihydrotestosterone, as well as growth hormones, like insulin and insulin like growth factor 1 (IGF-1), which all stimulate the production of acne.
Milk, Sugar and Insulin
Research conducted by Harvard School of Public Health in 2007 "found a link between those who drank milk and regularly suffered with acne. Those who drank skimmed milk suffered with the worst breakouts”. (Reilly, 2013)
It is suggested that it is not the anabolic hormones in milk alone that may cause acne, it is also milk's ability to trigger insulin production. It is believed that it may be the lactose or milk sugar that is also a likely cause of acne.
Results from studies have shown that the increase in insulin and IGF-1 when drinking milk is similar to the increase when high glycaemic food is consumed. Drinking milk can spike insulin levels 300 percent. Studies have found compelling evidence indicating high glycemic load diets aggravate acne. Consuming high glycaemic foods and milk leads to an increase in insulin and IGF-1.
A link between dairy and PCOS?
Studies have indicated that milk intake and PCOS were directly related. Further studies concur that there is a relationship between slim/low-fat or fat - free milk and an increased frequency of acne, a symptom of PCOS.
Low-fat dairy products may increase the level of insulin like growth factor I (IGF-I). Also, consuming low-fat dairy products has also been linked to an increase in androgen secretion. Research has also been suggesting that IGF-1 may be linked/ a cause PCOS.
Whole milk, on the other hand, has a higher concentration of estrogen and estrogen can reduce the level of IGF-1.
Can I still eat dairy?
Yes, you can still eat some dairy. If you suffer from PCOS, switching to goat or sheep dairy can help with acne.
Research has only identified skimmed milk as largely the cause of high insulin and acne. Studies have not found any relationship between cheese or dairy consumption on acne.
