Health, calcium and a vegan diet? No milk is needed for optimal health!

I don't have time to write a long reply now, but I will answer about calcium.

Milk doesen't give you stronger bones.
A recent metaanalysis published in the October 2006 issue of the British Medical Journal found, “The small effect of calcium supplementation on bone mineral density in the upper limb is unlikely to reduce the risk of fracture, either in childhood or later life, to a degree of major public health importance.”12 The authors state, “Our results do not support the premise that any type of supplementation is more effective than another.” Their findings mean dairy products are of no real-life bone-strengthening benefits. Even studies that used intakes of 1400 mg per day of calcium showed no benefit.

An editorial accompanying this metaanalysis pointed out, “Populations that consume the most cow's milk and other dairy products have among the highest rates of osteoporosis and hip fracture in later life.” 13 So does this mean consuming dairy products will hurt your bones?
