A new study published in JAMA has discovered that eating more fructose may be a contributing factor to the trend in obesity. The reason for this finding may be attributed to the slower rate at which fructose is metabolized within the body compared to glucose. The hypothalamus, the gland within the brain which controls appetite, does not respond very well to the signals of satiation when eating fructose. As a result, it stays active and hunger is not readily abated. In other words, eating fructose does NOT seem to reduce appetite as much as eating glucose.
The theory of why eating fructose, or fruit sugar, does not reduce appetite may be due to it being a more nutritious source of calories than other sugars. Thus, eating fruit sugar does not make us feel full as quickly because the body needs the nutrients and calories to survive. This makes sense for cavemen of yesteryear, but for humans today eating lots of fructose along with other sugars may be overloading our bodies with excessive calories. The result: increased fat storage! It doesn't help matters that fructose is cheaper than other sugars like glucose. This is why food manufacturers prefer to use this form of sugar as a sweetener.
