I don't like the way they mention 'super foods'. I think often it's what you take out (e.g. wheat, grains, starch) that works but I can't see that being recommended.

My prediction? The participants will eat 'healthy wholegrain' low fat diet with superfood added. They will not heal and therefore medics will claim that diet does not improve health, so carry on eating a 'balanced' diet and take the drugs.
