Yes. Cow’s milk is a perfect food. If you’re a calf.  Think dairy is good for you? More and more high-quality research is showing us that dairy is not all that it’s cracked up to be. 

Whether you drink milk or eat cheese for the calcium, protein, or just because it’s delicious and addicting, you should be aware that there are other options out there that are much more beneficial and satisfying.  More and more high-quality research is showing us that dairy is not all that it’s cracked up to be.

A large observational cohort study in Sweden found that women consuming more than 3 glasses of milk a day had almost twice the mortality over 20 years compared to those women consuming less than one glass a day. In addition, high milk-drinkers did not have improved bone health. In fact, they had more fractures, particularly hip fractures.
I am surprised that this study garnered so much mass media attention upon its release, as it highlights the deleterious side of milk, but I also think it is important to keep the findings in context. And when it comes to the health effects of dairy, the context is not so pretty:

  • In observational studies both across countries and within single populations, higher dairy intake has been linked to increased risk of prostate cancer .
  • Observational cohort studies have shown higher dairy intake is linked to higher ovarian cancer risk.
  • Cow’s milk protein may play a role in triggering type 1 diabetes through a process called molecular mimicry.
  • Across countries, populations that consume more dairy have higher rates of multiple sclerosis.
  • In interventional animal experiments and human studies, dairy protein has been shown to increase IGF-1 (Insulin-like Growth Factor-1) levels. Increased levels of IGF-1 has now been implicated in several cancers.
  • In interventional animal experiments[6] and human experiments, dairy protein has been shown to promote increased cholesterol levels (in the human studies and animal studies) and atherosclerosis (in the animal studies).
  • The primary milk protein (casein) promotes cancer initiated by a carcinogen in experimental animal studies.
  • D-galactose has been found to be pro-inflammatory and actually is given to create animal models of aging.
  • Higher milk intake is linked to acne.
  • Milk intake has been implicated in constipation and ear infections.
  • Milk is perhaps the most common self-reported food allergen in the world.
  • Much of the world’s population cannot adequately digest milk due to lactose intolerance.

So despite being very pleased that the public is glimpsing some of the evidence against milk in this recent study I think there is a far more powerful story; a story that takes into account the largely hidden context of diet and dairy research. There is a wealth of indirect evidence of very serious possible harms of consuming dairy foods, and, on the flip side, the evidence that milk prevents fractures is scant.

As we look beyond the headlines, it is hard to think that we should continue to consume the lactation fluid that exists in nature to nourish and rapidly grow calves.
