<-- see Help:Writing Fact Sheets and the articles in Fact Sheets Listing
Note that we want only enough information to convincingly support the assertion and counter inaccurate information. When making a point, it is important to find those sources that will result in the most convincing arguments, and to summarize findings in the most convincing manner, all without misrepresenting or exaggerating those sources.
Places to start for research:
Is there research showing that vegans are generally not deficient in calcium, or that non-vegans are?
-->
Fact Sheet
Summary
- Heavy advertising and public relation campaigns by the dairy industry have perpetuated the myth that cow's milk is essential for bone health and is a superior source of calcium.[1] <-- rewritten, old: Because milk and other dairy products contain calcium, Americans have been encouraged for decades to consume dairy as a way to strengthen their bones and fight against ???issues??? like osteoporosis. -->
- While it is true that calcium is essential for bone health and other physiological functions.[2], it does not follow that dairy is the healthiest source for calcium. Instead, getting calcium from dairy comes with risks not associated with plant sources (shown below
Evidence
- <-- rewritten. now this is a strong statement -->Harvard’s School of Public Health, the number one medical research school in the United States[3] says that milk is not the best source of calcium, and encourages people to look beyond the dairy aisle.[4]
- According to a study from the China Health and Nutrition Survey, a plant-based diet may actually be associated with a lower calcium requirement for bone health.[5]To reach the daily recommended amount of calcium, which ranges between 1,000 milligrams to 1,200 milligrams per day depending on one's age and gender[6], a person would have to consume large amounts of dairy, calcium-fortified foods, or supplements. However, due to dairy’s links to heart disease, type 2 diabetes, and other conditions, animal-derived calcium sources like dairy can cause plenty of health problems that non-animal sources do not.
- Despite often being touted as being healthy due to its calcium content, there are plenty of health concerns that outweigh the calcium benefits. The Physicians Committee for Responsible Medicine has noted that dairy can be the cause of some serious health issues, including heart disease, type 2 diabetes, and even Alzheimer's diseases.[7]

- In a 2003 study, researchers found that calcium balance is not affected significantly when calcium is provided by plant foods compared a diet that includes dairy products, concluding that a vegan diet is sufficient in calcium. [9]
Conflicting Claims
- In a 2009 study by Robert P. Heaney, known for his work with the Institute of Medicine to determine a recommended daily dose of calcium[10], the researcher concluded that without three servings of dairy per day, it would be difficult to be bone healthy.[11] Not only was Heaney a member of the National Fluid Milk Processor Promotion board[12], which was responsible for milk advertisements, but his research has been proven wrong: there are plenty of non-dairy sources of calcium, protein, and potassium making the consumption of dairy unnecessary.[13]

Focusing on 18-64 year-olds in 15 different provinces, the researchers found that vegetables, legumes, and cereals were the main sources of dietary calcium in its participants, and they concluded that Chinese adults are "severely insufficient in calcium and urging China to increase its milk and dairy consumption.[14]. This study is problematic, as it was funded by China's Ministry of Finance[15], and Chinese leaders have frequently championed the consumption of milk[16]. These findings have also been contradicted by other Chinese studies that show that a plant-based diet with its calcium sources did not show an increased rate of bone fractures.[17] In fact, vegan sources of calcium have other health benefits[18] that dairy sources don't.
Sources of Calcium
- The National Health Service (NHS) of the United Kingdom asserts that you can easily get enough calcium from just plant-based sources, such as green, leafy vegetables and dried fruits, in addition to fortified non-dairy milks.[19]
- Soy milk, such as Silk's brand, contains 50% more calcium than the average dairy milk, and Califa Farms' almond milk has 120 grams of calcium more.[20]
- One serving of fortified orange juice contains 500 mg of calcium, which is 50% of the Recommended Daily Allowance of calcium, and half a cup of tofu can have up to 860 mg, or 86% of the RDA.[21] One cup of cow's milk accounts for only 276-352 mg of calcium, thus requiring more servings than plant-based sources.[22]
Dietary Guidelines
- The amount of calcium necessary differs depending on one's age and gender.
- For women between the ages 18 and 50 and men between the ages of 18 and 70, the Recommended Daily Allowance is 1,000 mg of calcium.[23]
- Women who are over the age of 50 and men over the age of 70 require more calcium to maintain bone health. The RDA for this demographic is 1,200 mg of calcium.[24]
