There, I said:
We need to be a bit sceptical about the science and the motivation and presuppostions of those who are writing.
This is a very well written article on the same topic by Gary Taubes: Do We Really Know What Makes Us Healthy?
There is a lot of dogma out there about health, fitness, diet and strength. Think carefully about all this stuff. Weigh up the arguments. Try to see if there is anyone making money out of you! Nothing against business but we need to be careful not to be sold dud information.
Anyway, a fascinating and instructive piece.
