But there is a huge distinction between HFCS (High Fructose Corn Syrup) and the fructose contained within fruits.
For example: apples and other fruits are considered to be healthy because of the antioxidant flavonoids they contain. However, these flavonoids are poorly absorbed into the bloodstream. The fructose within apples stimulates the production of uric acid in the body, which in turn provides much greater plasma antioxidant capacity which results in much greater antioxidant protection.
It isn't by accident that Dr Max Gerson used the juice of apples (high fructose) with the juice of carrots in his successful anti-cancer protocol.
Mercola should definitely be more careful when he labels all fructose as deriving from the same stable, and being detrimental to health.
