(Natural News) Researchers from King Abdulaziz University in Saudi Arabia have found that aspartame, a common artificial sweetener, has a damaging effect on the brain. More specifically, they found that the long-term consumption of aspartame increases oxidative stress in brain tissue and disrupts neurotransmitters, which harms physiological functions.

  • For the study, the researchers assessed the effect of aspartame consumption on neurotransmitters and oxidative stress in the brain of rats.
  • Aspartame has been used as an alternative sweetener among people with diabetes and for weight management.
  • They randomly divided the rats into four groups: one group served as the control group, while the remaining groups were given aspartame at a dose of 50, 75, and 125 milligrams per kilogram (mg/kg) body weight per day, respectively.
  • The treatment period lasted for 40 days.
  • The researchers then collected blood and brain samples after 10, 20, 30, and 40 days from the start of the experiment for biochemical analysis.
  • The results showed that aspartame consumption reduced the antioxidant activities of glutathione and superoxide dismutase, while elevating the amount of oxidative stress by increasing malondialdehyde levels.
  • Aspartame intake also significantly reduced the levels of the brain neurotransmitters serotonin, GABA, and dopamine and increased the level of acetylcholine and norepinephrine.
  • The effect of aspartame is dose-dependent.
  • The findings of the study were published in the African Journal of Traditional, Complementary and Alternative Medicines.

In conclusion, these findings suggest that long-term aspartame consumption increased oxidative stress in brain tissue and disrupt neurotransmitters.
