Now I’m no nutritional biochemist but I think that diets which completely cut out so many food groups are bad for healthy, active individuals.
I have a couple of friends who swear by it, they claim that the food groups in their diet were the only ones which were eaten by our palaeolithic ancestors (since when did they have olive oil 40,000 years ago?).
Well our ancestors did many other things which would be considered nothing short of barbaric now. E.g. cannibalism, blood drinking and their omega-3 didn’t come from salmon or fish oil, no it involved cracking open animal skulls and sucking out the insides. They ate ANYTHING which was edible and didn’t eat them first.
Well these ‘experts’ also forgot to mention that these people also lived to a ripe old age of 35 (there would been many dangers, but surely diet played a part in deciding there lifespan).
I’m convinced that eating the right GI foods at certain times is very important but is it really wise to cut out wholegrains, dairy and even pulses(!) from the diet? completely?
