It's like the sugar tariff in the US. Just a complete garbage policy that imposes a small individual cost on everyone who buys sugar but benefits like 4 companies with massive profits who lavishly lobby to keep the price floor in place.
The sugar tariff is indirectly responsible for the deaths of many Americans because high fructose corn syrup is used in lieu of regular sugar in many foods and beverages instead. Fructose is extremely damaging to the body because the liver can barely metabolize it and most of the excess goes to liponeogenesis which ultimately manifests itself in tremendous buildup of visceral fat, with all the implications that carries. Meanwhile glucose is typically mostly stored alongside muscles as glycogen, and the human body can store far more glucose effectively than fructose.
The most common forms of high fructose corn syrup are HFCS-42 and HFCS-55. HFCS-42 has 42 percent fructose and HFCS-55 has 55 percent fructose, with the remaining sugars being primarily glucose. As a comparison, common table sugar (sucrose) is 50% fructose and 50% glucose. While there are public health problems caused by over consumption of sugar, simply switching to sucrose is not really a solution.
They are all bad when consumed in large quantities because the human body can only metabolize a small amount of fructose per day. One fruit contains little total sugar and also contains fiber which is an important fermentation substrate which aids in reducing the quantity of fructose entering the body.
