A team led by neuroscientist Fernando Gomez Pinilla of the Los Angeles campus in California designed an experiment that took 5 days to train mice through the maze, feeding only water and regular bait; then within 6 weeks, A 15% fructose solution was used instead of water, and half of the mice were fed a mixture of linseed oil and fish oil. Pinilla explained that carbonated beverages generally contain 12% sugar, so the fructose solution fed to mice is equivalent to carbonated beverages; OMEGA-3 fatty acids rich in linseed oil and fish oil have the function of maintaining synapses in the brain.
The results of the experiment showed that all mice passed the labyrinth at a slower rate, and the half of the mice fed the mixed oil passed faster than the other half.
After dissecting the mouse’s brain, the researchers found that the high concentration of fructose that the mice ingested during the experiment inhibited the plasticity of the brain’s synapses, and the insulin function in the hippocampus of the mouse brain. The disorder, and insulin has the effect of adjusting sugar.
According to Pinilla, the destructive effect of fructose on the brain of mice is likely to also occur in humans. Therefore, he suggested not to take too much sugar in the diet, but also to eat more foods and edible oils rich in OMEGA-3, such as salmon, tuna, walnuts, olive oil and so on.
