Is Dairy Dangerous?
You know the slogan. Milk does a body good. Well, no, not really.
Dairy has been shown to have a negative affect on endothelial cells. This cell layer is a one cell thick lining of all of our blood vessels. Endothelial cells manufacture a protective molecule of gas called nitric oxide, which protects our blood vessels. It keeps our blood flowing smoothly, it is the strongest dilator of our blood vessels, it inhibits the formation of blockages, and it inhibits inflammation.
Dairy, along with all animal products, damage that layer of endothelial cells in our blood vessels. Without that functioning layer, nitric oxide cannot be produced. Without enough nitric oxide, the plaque blockages build up eventually creating heart disease and strokes.
Dairy is loaded with hormones. Even if you buy organic milk without recombinant bovine growth hormone (rBGH), it will still have high hormone levels. Why? Because dairy cows are always kept pregnant so they have lots of circulating hormones that pass to the milk. This is not good news considering that hormones have been linked with an increased risk of breast, prostate, ovarian, and testicular cancer.
Dairy has been shown to increase hip fractures and high mortality. One study has shown that high milk intake was associated with higher mortality in one cohort of women and in another cohort of men, and with higher fracture incidence in women.
