Move Over, Milk
“So, are you going vegan?”
I’d already stopped eating meat and fish for ethical reasons, so why did my friend’s question send a chill down my spine? My eyes got wistful as visions of melty grilled cheese sandwiches, salads of sun-warm tomatoes and fresh, milky mozzarella, and the sharp, salty bite of Greek feta danced in my head.
“No way,” I sighed. “I could never give up cheese.”
For years, it seemed I had an itch that only cheese could scratch. More than a casual dalliance, cheese and I were carrying on a full-blown love affair. Not only did cheese bring me so much joy, it was rich in bone-building calcium. It was delicious—and good for me! How could I even think about giving it up?
But the more I learned about the dairy industry, the more I realized that cheese and I didn’t share the same values. For me, the hardship endured by dairy cows and their calves was just too much of a turnoff.
It was time for me to break up with the love of my culinary life.
The Bone of Contention
Still, I was worried. In my zeal to do no harm, would I end up harming my own health? For strong bones, the Institute of Medicine recommends adults consume between 1,000 and 1,200 milligrams of calcium daily, depending on age, and cheese and other dairy products are among the richest food sources of this mineral. As a result, many experts (including my own doctor) strongly recommend we consume three dairy servings daily.
Was it even possible to give up dairy without weakening my bones?
For answers I scheduled an interview with Dr. Walter Willett, chairman of the Nutrition Department at Harvard’s School of Public Health. He’s also been co- and principal investigator of a landmark study that has tracked the lifestyle habits and health outcomes of 238,000 nurses since 1976, with results that have shaped current health recommendations on heart disease, diabetes, and many
I was floored when one of the first sentences out of Willett’s mouth was this: “Dairy is not the most important food for bone health.”
He says, “The highest fracture rates in the world are in countries that drink the most milk and consume the most calcium.” In many African countries, women consume only 300 milligrams of calcium daily (the amount in roughly one serving of dairy), yet their hip fracture rates are low. The same is true for Japan and Peru. Compare that to the United States, where we consume three times more calcium and dairy, and our hip fracture rates are the highest in the world.
The Nurses’ Health Study found that postmenopausal women who had been consuming 2.5 or more servings of dairy a day had the same risk of bone fractures as women who consumed fewer servings. And when Australian researchers compared the bone densities of 105 vegan Buddhist nuns to 105 nonvegetarians, they found no difference between the two groups. The nuns had bones that were just as
