Nutrition guidelines are handed to us by government departments and most of us will blindly assume that the guidelines are both accurate and up to date.
The truth of the matter is that much of the guidelines you see are heavily lobbied for by industry and don’t represent a true unbiased scientific opinion of what is the truth.
Government mandated guidelines and marketing health claims are usually only an interpretation of some of the science available and should never be taken as a fact that can be applied to all people.
When it comes right down to it, your body and your health is your responsibility and requires you to do some digging to find out if the guidelines you’re told and the claims you read are even worth the paper they are written on.
In just about every case the claim or guidelines you’ve read have much more than just your best interest at hand.
