Fructose doesn’t just enter your body through the consumption of fruit juices, cookies, and chocolate. Scientists from Yale University (USA) claim in recent research that the brain also produces it. The organ would convert its own energy source into sugar, which is known to have deadly effects on the body. And it would support the fact that people who have fatty or excessively sugary diets would be more at risk of diabetesheart disease andobesity.
Transformation of glucose into fructose in the brain
The researchers scanned the brains of eight healthy people as they received glucose intravenously. Using a special type of imaging, they were able to measure sugar concentrations in their brains. After just 10 minutes, they noted an increase in brain glucose levels. After an hour and a half, fructose levels also increased slightly.
They think the fructose concentration is due to reactions in the brain known as the polyol pathway. This turns glucose, the body’s energy source, into another sugar known as sorbitol. It is then converted into fructose. Blood samples were also taken to measure sugar concentration for the study published in the JCI Insight review.
Fructose produced in the brain
“In this study, we show for the first time that fructose can be produced in the human brain,” said lead research author Dr. Janice Hwang. By showing that fructose in the brain is not simply due to food consumption, we have shown that it can be generated from any sugar you eat. This adds another dimension to understanding the effects of fructose on the brain.
Fructose is unhealthy when artificial
the fructose is a commonly used sugar in the food industry. It is present artificially in sugary drinks, syrups, honey, juices and desserts in supermarkets. Fructose is found naturally in fruits, but their fiber significantly slows sugar absorption and neutralizes damage to the body, according to recent Spanish research.
