When i can prove somebody wrong. And today, ShadowAdler, its your turn. A response to ' RDA for actual thought'. Now much as i initially wanted the government to be wrong (ever anti establishment), we do actually need calcium. And cavemen did get it.
Hit the jump to find out why..perhaps our collective learning will justify how long this took me.
Calcium can be found in the following things:
turnip greens, okra, brussel sprouts, sesame seeds, white beans, bok choy, almonds, broccoli, salmon, rhubarb, collard greens, spinach (or any leafy greens), and peas. Furthermore, there is enough Calcium in leafy greens to make up your RDA, and there was probably not a shortage of veg.
Calcium is regulated in the body by vitamin D, and can help to retain a lot of it..much like when you intake vitamin C with iron to help absorption. There was definatly no shortage of sunlight.
So if you are intaking enough vegetables (and appararently salmon...), and getting enough sunlight, you will retain enough calcium. A recent NHS study also concluded that halving your calcium intake to 350mg only led to problems with osteoporosis in old age...and cavemen didn't live long enough to suffer that.
And, who would question a few creaky bones in the older members of the pack? I certainly don't on my grandma, and i am way past the 'ug' stages.
