Nutrition

Calcium

NOTE: Nutrition cannot realistically be fragmented, or divided, into its individual nutrients (protein, fat, carbohydrates, vitamins, minerals, etc.). A whole food is exponentially superior to the sum of its measurable nutrients. In speaking of fragmented terms such as “protein,” “carbohydrate,” and “fat,” we must always remember that real food comes in a whole form.

Calcium

Cows are not the source of calcium.

What is Calcium?

Calcium is a mineral that, like all other minerals, is assimilated by plants into food. Calcium does not come from milk. The calcium in milk comes from the grass the cow eats. Likewise, we obtain plenty of calcium through whole plant foods. We all – man and animal alike – get our calcium from plants. 

Is Dairy Good for Bone Health?

Modern nutritional recommendations promote the idea of drinking animal milk for healthy bones. This is completely false, as evident by that fact that higher consumption of dairy consistently correlates with higher rates of osteoporosis and bone disease (Michaelsson, et al). For those who promote consumption of animal milk for bone health, it is a perplexing fact that populations that consume higher amounts of calcium – particularly through dairy products – have higher rates of fractures (Hegsted).

Our bones require a balance of minerals, specifically of magnesium and calcium, to develop and maintain proper structure. Animal milk (dairy) contains excessively high levels of calcium without the balance of magnesium, resulting in an imbalance of minerals and improper bone formation. Furthermore, milk – like other animal-based foods – puts the body in a state of metabolic acidosis, which the body corrects by pulling calcium out of the bones. Although we drink milk to get calcium, we might actually be causing our bones to lose calcium because animal foods, including milk, make the body acidic. Calcium is easily and best obtained through eating whole plant foods.

Conflict of Interest

It is common to see research promoting the consumption of dairy for health that is funded by the dairy industry (for example, see the Conflict of Interest Statement on this article). It may be worthwhile to consider that sales and funding can (and often do) have a very significant effect in determining the outcome of “research,” whether apparent or not.
