How could this ruling come about?

Obesity experts appalled by EU move to approve health claim for fructose
But the EU has now ruled that food and drink manufacturers can claim their sweetened products are healthier if they replace more than 30% of the glucose and sucrose they contain with fructose

I read that a can of sugar sweetened soft drink has 39 g of sugar (sucrose). This is 19.5 g glucose, and 19.5 g fructose after ingestion. If a third of the sugar is replaced by fructose we get consumption of 13 g glucose and 26 g fructose. The guide for what fructose we can cope with each day is 15 to 25 g, so we are already over that limit with just one drink.

The suggestion is that this is healthier because whereas glucose raises the blood insulin level, fructose does not. Here is a good summary of the problem:

Sugar Is a Poison, Says UCSF Obesity Expert

You don’t fix a problem by switching off the warning light. People will be attracted to the “Contains healthy fruit sugar!” on the pack.

My prediction:
Fructose is processed by the liver to fat (triglyceride). There’s a host of bad consequences, but one I will single out. On a blood test the fructose drinkers will be told they have a bad lipid profile and will be put on statins. The statins will block the liver from making cholesterol, which is needed among other things as a component in the lipoproteins that transport fats to where they are needed or stored. Some fat from fructose will stay in the liver and the person will develop non-alcoholic fatty liver disease. If the fructose is added to alcoholic drinks that will be a double liver problem as alcohol follows the same pathway, but at least you know you drank it. In 10 years there will be a lot of people needing a liver transplant.

As in Alice in Wonderland, “When I use a word,”  Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.” So, healthy has just been redefined.
