High doses of fructose in the diet negatively affect the immune system, Nature reported referring to a study of the Swansea University, University of Bristol, and the Francis Crick Institute.
The authors of the study examined the effects of this type of sugar on mice. Glucose triggered glutaminolysis and oxidative metabolism in their bodies – processes that increase the level of inflammatory cytokines.
Research has shown that inflammatory responses of the immune system caused by excessive consumption of fructose lead to organ dysfunction as well as damage to cells and tissues.
In turn, scientists at the University of Colorado in the United States found that fructose, which together with glucose is part of sugar, as well as uric acid, which is formed during glucose metabolism, increases the risk of behavioral disorders such as attention deficit hyperactivity disorder.
Researchers have found that fructose stimulates impulsivity, novelty, quick decision-making, and aggressiveness.
