Based on the massive amount of evidence linking 'chemicals from plants' (polyphenols, glycosinolates and others) with (in the main) markedly positive effects on human biochemistry & physiology, this appears to be a very good idea.

It's noteworthy that the 'five (vegetables/fruit) a day' mantra is a familiar one in the UK and I guess elsewhere. But rarely does anyone explain precisely why this is a recommendation given that it's quite possible to supply the required fat, protein, carbohydrate, vitamins and minerals without consuming significant amounts of fresh fruit and vegetables (using supplements).
