yes, definitely. They are also finding too much calcium in one go isn't great. I guess with all the small bony fish, you get a lot of calcium at once, which actually has a negative effect because your body eliminates more than it saves. You also need D to absorb the calcium correctly. BUT...I was thinking with your cold icy weather, people probably fall more frequently leading to more hip fractures.

I am very interested in how different diets effect health issues. It's quite amazing.
Like CE's area has one of the lower rates of OP, even though it's a high rate of animal protein consumption. I was thinking that it's warmer there, more vit D and less falling?

I don't know...but the studies are on spread sheets, and cool spreadsheets with lots of data give me a high.
