Bones contain calcium, potassium, manganese, magnesium, silica, iron, zinc, selenium, boron, phosphorus, sulfur, chromium, and more – but the dairy industry tries to tell us all we need for strong bones is calcium?

Cows eat nothing but grass – and we can’t compare with their bone strength (granted, they have different stomachs than we have – but I also haven’t asked you to eat grass…).

Vegetables contain enough calcium for strong bones. Plus they contain all the other minerals healthy bones require. We don’t need fortified, adulterated, hormone-injected dairy products for our bones. Also, the daily requirements for calcium seem to be put artificially high: In one study in Africa, women took in about only half the recommended dose and maintained excellent bone health.

Nuts are also full with all the different minerals we need. The problem with nuts of course, are allergies and reactions to lectins. So, if nuts don’t agree with you, don’t push them! And beware of rancid/roasted nuts! Their bad fats do more harm than good whereas fresh nuts contain beneficial omega-3’s.

Another problem with dairy is that it provides protein – and the Standard American Diet (SAD) contains too much protein as it is. We are omnivores by nature – once in a while a piece of meat (not deli!) between our teeth provides us with essential nutrients like vitamin B12 that are hard to come by otherwise – just not every day. But too much protein leaches out calcium from the bone – at least that is one theory. It says that the metabolic products of protein digestion are acidic, and need alkaline buffering for buffering, and so calcium is leached out of the bones. Regardless if this hypothesis is true, high protein (meats and dairy) diets have been linked to osteoporosis.

Lists of calcium contents, comparing dairy with vegetables, often show higher values for dairy products. What these lists don’t tell you is that calcium from dairy is not as easily absorbed as from vegetal matters (fruit, vegetables, grains, legumes, nuts – everything that has really grown) because high protein hinders calcium absorption.

Don’t think you get much benefit from a calcium supplement! Number one, the calcium without the other minerals will not do you much good. Number two, as a physician I am all too familiar with that oblong white spot on an x-ray of the bowels – the not-absorbed calcium pill. You better put your money into fresh produce!

Did I mention movement for bone health? I should.
