Vegan Calcium Needs: Working Through the Myths

Quite a few popular vegan websites and books make the claim that vegans don’t need as much calcium as omnivores. The theory dates to some interesting research from the early 1990s which found that hip fracture rates among different countries increased as per capita protein intake went up.

The observations were backed by decades of clinical studies, too. As far back as the 1920s, nutritionists were showing that feeding meat to subjects caused them to excrete more calcium in their urine. Theoretically, this is because protein has an acidifying effect on the blood. Calcium is leached from […]

Good News About Vegan Bone Health

Just published this month in the journal Osteoporosis International, a new study revealed that bone health was similar between vegan Buddhist nuns and omnivore women even though the vegans had much lower intakes of calcium and protein.

The study involved 105 vegan nuns and 105 omnivore women in Viet Nam. Average calcium intake was 375 mg per day for the vegans and 682 mg for the omnivores. (Some of the vegan women did use very small amounts of milk in meals.) Vegan women also had low protein intakes averaging around 35 grams per day compared to more moderate […]

Vegan Calcium is the Best Calcium

A friend asked me today whether I worry, as a vegan, about calcium. Well, I do worry about it, but not because I’m vegan. Calcium is an issue for all women. No matter what type of diet you follow, it’s important to identify good sources of this mineral.

Plant foods that are good sources of calcium include many leafy greens, like kale, collards, and mustard greens; broccoli; some legumes like black beans and vegetarian baked beans; blackstrap molasses (but not regular molasses); fortified soyfoods; fortified juices; and tofu if it is has calcium listed as an ingredient.

Be An Effective Vegan Advocate: Take a Calcium Supplement

Some recent research has shown that vegans have lower calcium intakes than omnivores and that they have a higher risk for bone fractures.

That’s bad news for vegans. It’s also bad news for farm animals. Anything that makes a vegan diet look inferior is likely to convince more people to eat animal foods.

So what can you do about that? Some vegans choose denial. They say a vegan diet is better for bone health and they cite old—usually outdated—research to prove it. Many vegans cling to the unproven belief that those who eat plant diets need […]
