in that article at the bottom he essentially says "this test doesn't hold all the answers. HFCS may not be that much worse than sucrose, but you should still attempt to avoid sugars and refined carbs as much as possible"
also some of the comments and references in them are pretty good. for both arguments.
who knows, in 50 years we might learn that HFCS is absolutely 100% the cause of obesity and a huge cause of cancer. or we may find out that it really isnt.
what i do know is ive seen a lot more solid independent research pointing towards HFCS and sugars being absolutely terrible for us, and most of the counter arguments are trying to disprove the research, but rarely pointing towards sugars being good for us. and very little research going the other way.
like, heres all of the facts about this subject and why "we think thes facts mean A". you read more people arguing and reaching about minute points than you read people saying "these facts don't mean A, they mean B"
at the end of the day, nothing that any of us read or watch or hear should be taken as absolute fact but instead should be used as information to form our own opinions.
