Should we start talking about “Low Fructose” instead of “Low Carb”……

There is no good research backing up the concept of "5 a day",

I believe it was a number plucked out of the air by the American powers that be after being lobbied by the Californian fruit and veg growers.

@CherryAA You seem to be a bit mixed up, but with the correct recommended actions...

Firstly our body can't make fructose, and does not need fructose. But our body was designed to use fructose to quickly build up fat so we could cope with little food in winter.

When we eat table sugar, it is broken down into fructose and glucose before it enters our blood. Pure fructose as in fruit comes into our blood as floccose. Fiber slows down the process, so giving our body longer to cope with the fructose.

ONLY our liver can use fructose, if the insulin level is low, the lever converts fructose into glucose, if the insulin level is high, the fructose is converted into triglycerides. If the insulin level is VERY low, the liver can convert triglycerides into glucose.

If the rate the liver makes triglycerides is faster than they can be used by the rest of the body, then they build up as fat in the liver cells.

Thank you for your comment, but I don't think I am mixed up, in so far as what I have written is consistent with the theory proposed in the video. Watch the video at 24 minutes citing the polyol pathway and a study done in 1984. The theory is put forward by Dr Gary Fettke and talks about endogenous fructose production. Whilst his theory may be bunkum, so may many other theories, this particular theory makes a lot of sense to me where he talks about a tenfold increase of the conversion of glucose to fructose in the presence of high insulin. There has to be some reason why carbohydrates are fine for some people and toxic to others - the concept that that is some function of some metabolic disordering within the body - if only we knew which makes sense to me. The concept that that would be insulin in the context of hyperinsulinaemia ( high levels of insulin ) being implicated in dozens of diseases makes that the most likely candidate. He views the study cited as indicative of that - I guess we won't know if he is right until other studies are done on the subject. For now my money is on him proving to be right.

The fact are known: in an healthy diet is useful to avoid foods with added sugar and fructose is a sugar. So HFCS and table fructoses being added sugar should be avoided.

And there's a paper from Diabetes Care stating that fruit juices increase the risk of diabete insurgence, but not whole fruits.
