Ah supplements. So many opinions and everyone's an expert. This book is really good and could help be a reality check for lots of folks. People assume supplements are under the same sorts of rules as foods and drugs, but that is far from the truth. Everyone should read up on where and how that diverged.

Besides that, though, the story of discovering the deficiencies and vitamins are worth digging into. The stops and starts, false leads, drama, public opinion shifts - just regular science stuff. If you don't have a science background, I think this helps explain following all the leads, having hypotheses, being wrong a lot, one study doesn't prove it, and a lot of things that get lost in the usual day to day reporting on science. At one point other scientific discoveries like germ theory and antibiotics hold up the deitary deficiency theories. And with scientists popping poo pills and regurgitating meat - glad we don't do those experiments anymore - what more do you need? Read it.
