In spite of their supposed numerous health benefits, it has been speculated that dairy products may negatively impact your endocrine system by causing so-called “hormone spikes” that could be detrimental to your well-being in the long term. According to an interview published by Harvard University, the link between cow’s milk and estrogen is being thoroughly investigated, although farm production practices may be the answer to the unusually high estrogen levels in milk. Since cows are milked more than 300 times a year to increase sales, they are pregnant during most of that time, and therefore produce the hormone in much higher quantities (33 times more estrone sulfate, an estrogenic compound).
Is milk itself dangerous?
Natural milk, whether of vegetable or animal origin, is not dangerous in the slightest; however, farm animals are sometimes administered growth hormones that may harm consumers. Also, it is normal for some hormones to exist in milk, and as long as they are natural and in normal quantities, they shouldn’t have a significant impact on your endocrine system.
Can milk provoke acne?
Due to the use of growth hormones in the dairy industry, most dairy products are very high in IGF-1, a growth factor that is also present in the human body during adolescence, when everyone is most likely to experience acne. However, this doesn’t happen to everyone who drinks milk but diet may have some influence on acne. Testosterone in milk is also converted to DHT, which could have a slight influence on hair health.
How does the liver deal with dairy products?
The milk we drink today is different from the milk our ancestors used to drink, as the dairy industry focuses on increasing production at the expense of the consumer’s health. One of the main functions of the liver is to filter and destroy toxins in your body. Therefore, if the food you eat is toxic (i.e. contains growth hormones or additives you don’t need) the liver may get “overworked”, which may lead to tiredness, fatigue and even cirrhosis in the long term.
All toxins from alcohol and fatty foods are filtered and excreted with the help of your liver and kidneys. Dairy products like cheese are particularly hard to digest, so if you wish to avoid fat build-ups around your liver, avoid overconsumption or have organic light cheese instead whenever possible. Organic farms claim to milk cows for five months a year or during the early stages of their pregnancy, as it is normally acceptable.
While there is no conclusive evidence to suggest that dairy products have a serious impact on your hormones, you might consider switching to organic milk or a dairy free milk alternative if you are concerned, or exclude it from your diet for a while and see the results.
