That should be one of the basics in medical school. But, they medical staff really do not know shit about nutrition. I had a bone density test done. On the questionnaire they only asked about cows milk and cheese. No other forms of calcium. If I wanted to I would have had taught her basic nutrition and how a cow gets the calcium and how many more foods have calcium and many of them have way more than cows milk. She thought that one could only do dairy or take a supplement. I do take a supplement but I also eat calcium rich foods as well ask goats milk, soy milk and rice milk.
