Dairy Can Cause Early Puberty, Menstruation & Acne

Dairy is a very common food sensitivity that most people don’t even realize they have.

I stand by the comical (yet true) saying that functional medicine doctor Dr. Steven Noseworthy stated at numerous conferences “Wheat is the devil and Dairy is the henchman!” 

Food sensitivities can  manifest in many different ways in the body. The most common foods to cause issues are wheat, dairy and eggs.

Dairy in particular can cause diarrhea, constipation, tonsil stones, mucus, lymphatic congestion, inflammation, stomach pain, gas, bloating, acne and even early menstruation in young girls. 



Still on the fence about cutting back or being dairy-free? Here are some studies that I have pooled together on how drinking milk can alter your body:

Acne In Teenagers:

A cohort study of >4000 teenage boys found a positive association between drinking skim milk and acne. They concluded that the acne is a result of the androgens (hormones) found in milk along with the increase in Insulin-like Growth Factor 1 (IGF1) associated with milk consumption.

Early Puberty & Menstruation

Milk consumption in early childhood may contribute to accelerated menstruation by up-regulating early growth in body size. Milk consumption may have both immediate as well as indirect and long-term impacts on timing of the timing of sexual maturation.

Steroid hormones are very potent compounds in dairy foods, which exerting profound biological effects in animals and humans. Most of the previous knowledge about the steroids is according on their physiologic and sometimes supra-physiologic concentrations of steroids but recently it is found that these compounds even at very low doses may have significant biological effects. Special concern should be paid to the effects, which may occur during certain and sensitive time points including perinatal and pubertal periods

The University of Medical Sciences in Iran conducted a study in 2013 that looked at 134 pre-pubertal girls age 4-12  and followed them for 6.5 years. They observed that pre-pubertal intake of milk, but not cheese and yogurt, quickened the time that girls started their period.





Breast Cancer 

The literature is quite mixed in terms of correlation of milk/dairy consumption and risk of breast cancer. Some have found no risk of BC and dairy consumption and others have found risk of BC and milk consumption but not with cheese and yogurt. My opinion is that dairy is a congestive food, it does produce mucus and it does congest the lymphnodes & lymphatic system.










Genetic Considerations:

Genetics: If you’ve done a genetic test such as 23 and me you can actually see if you are predisposed to having issues with dairy/lactose. Go to 23andme.com and when you log in you will go to “Wellness Reports.” In there you will see “Lactose Intolerance.” Click on it and you can see if you have 1 or 2 mutations in that gene. Be advised if you have only 1 mutation (AG) , it will state you are “likely not lactose intolerant.” This is partially true. If you have 1 mutation and 1 normal gene, you CAN tolerate dairy to a degree, but your body is less efficient at breaking down lactose and you can experience symptoms/ GI distress/tonsil stones when you eat too much dairy. Whatever the amount that you’re able to tolerate without symptoms is totally unique to you.

Dairy In Other Countries: Have you ever heard about people going to Europe and eating all the bread and cheese their little hearts desire, and feeling totally okay?! I have heard this as well! And this could be entirely plausible as to why people can eat those foods over in Europe and can be intolerant to them in USA.

The kind of cow (A1-Beta Casein type cows vs. A2 cows) , the food the cows are fed (grain fed vs. grass fed), the environment the cow is living in (stressed out or treated poorly vs. happy cows). It is a fact that cows that are grass fed produce more Conjugated Linoleic Acid (CLA) than those that are grain fed. And it is well know that animals that are raised in a stressful, crowded environment produce more cortisol (stress hormones).

Humans Don’t Need Milk: There is no need for humans to consume the milk of cows. There are many studies that indicate milk doesn’t prevent osteoporosis. In fact, it was observed that the countries with the highest  milk intake had the highest rate of bone fracture, and the lowest consumption of milk had the lowest rates of osteoporosis. Milk doesn’t naturally contain Vitamin D, it was made mandatory to fortify with Vitamin D as the concern of Rickets rose in the 1900s. Milk consumption even has a correlation with an increased risk of Type 1 Diabetes.

In conclusion, you have to make the decision that is best for you. And any changes you make, remember, small ones are better than none at all!
