Sugar inhibits your brain’s ability to learn, but omega-3 fatty acids can prevent the damage.
A UCLA study published in the Journal of Physiology indicated that a long-term diet high in fructose adversely affects the brain’s ability to learn and store information. Fructose is a naturally occurring fruit sugar, but it’s also an omnipresent food additive. The average American consumes 47 pounds of cane sugar a year and 35 pounds of high-fructose corn syrup (which is part glucose and part fructose). Researchers fed two groups of rats a fructose solution instead of water for six weeks. One group was also fed omega-3 fatty acids (partially from flaxseed oil). Both groups were trained to run a maze, but after six weeks, the omega-3 group was able to remember the route far better; the group that received only sugar and no omega-3s showed a decline in brain activity and had become more resistant to insulin.
