Dairy and Cancer: Experts Are Concerned. Are You?

Cancer and Dairy: Experts Are Concerned. Are You? | Meat Your Future


After analyzing the risk for female cancers across 5 continents and 40 countries, researchers concluded that they are most concerned about the role of dairy.

That’s right. Dairy is strongly associated with increased ovarian, uterine and breast cancers.

There are likely several factors at play, including the hormonal content in milk, which is true even for dairy products labeled “no hormone added” or “organic” (even if no *additional* hormones were added, milk products still contain large amounts of hormones that are naturally produced by pregnant and lactating cows).

Dairy also contains animal proteins, the main one being casein. And animal protein in general, including casein in dairy, has a higher proportion of essential amino acids, which triggers our body to produce larger amounts of IGF-1, a hormone associated with increased cancer risk and proliferation.

Those are just a few of many problematic health issues associated with dairy.

From an environmental perspective, dairy (and meat and egg) production has an immense and unsustainable resource footprint.

And, of course, animals foods involve inherent cruelty. With regard to dairy in particular, cows and other mammals don’t produce milk unless they are impregnated and have a baby. So, cows and other animals used for milk are repeatedly impregnated to get and keep them lactating. And, because we want their milk for ourselves, we take away their calves shortly after they are born (and, in the case of the male calves, they are usually killed early in their lives as a “byproduct,” often for veal).

There is no reason to consume dairy. And for the vast majority of human history, we never consumed dairy (other than from our own mothers as infants). We need to get back on-track and, for all these reasons, ditch dairy (and other animal foods) forever and for good.

“Meat was most closely correlated with the breast cancer incidence (r=0.827), followed by milk (0.817) and cheese (0.751)…. Milk was most closely correlated with the incidence of ovarian cancer (r=0.779), followed by animal fats (0.717) and cheese (0.697). SMRA revealed that milk plus cheese make the greatest contribution to the incidence of ovarian cancer ([R]=0.767). Milk was most closely correlated with corpus uteri cancer (r=0.814), followed by cheese (0.787)…. Among dietary risk factors, we are most concerned with milk and dairy products[.]”

“When we think about it, the health problems associated with consuming the milk and dairy products of other species should not come as any surprise. No other species consumes milk regularly past the weaning period and certainly not from another species—and, as mentioned above, we humans have also not being doing so for the vast majority of our own evolutionary history.”

“The [British Medical Journal] study included more than 100,000 people and found that women who drink three or more glasses of milk per day had a 60% increased risk of a developing hip fractures and a 93% increased risk of mortality and that for each glass of milk per day the risk of “all-cause mortality” increased by 15%.”
