This is not the 1st time sugar has been connected to declines in brain function. In the year 2012, researchers inquired the impacts of high-fructose syrup, similar to high-fructose corn syrup (HFCS), a very cheap sweetener 6 times sweeter in comparison to the cane sugar, which is utilized in several soft drinks, processed foods, condiments, and even few baby foods.
The team sought to investigate the impacts of a gradual intake of this super-processed, concentrated type of fructose. They fed rats a fructose solution as consuming water for 6 weeks, and then tested their capability to remember their way out of a maze.
The rats fed fructose syrup indicated important impairment in their cognitive capabilities—they attempted to remember their way out of the maze. They were very slower, and their brains demonstrated a decline in synaptic activity. Their brain cells had confusion signaling each other, troubling the rats’ capability to think clearly and recall the route they had learned 6 weeks initially.
Furthermore, the fructose-fed rats indicated symptoms of resistance to insulin, a hormone that controls and manages your blood sugar and synaptic function in your brain. Because insulin is capable to pass through your blood-brain hurdle, it can trigger neurological procedures that are significant for learning and memory.
Eating large amounts of fructose might block insulin’s capability to regulate how your brain cells store and utilize sugar for the energy required to fuel thoughts and emotions.
In this situation, a 2nd group of rats was provided omega-3 fats in the type of flaxseed oil and DHA (docosahexaenoic acid), in addition to the high-fructose diet. After 6 weeks, this group of rats was capable to navigate the maze better and faster in comparison to the rats in the non-DHA group.
The researchers summarized that DHA is protective against fructose’s harmful impacts on your brain. DHA is necessary for synaptic function—it assists your brain cells transmit signals to one another, which is the mechanism that makes learning and memory possible.
Your body cannot produce that much DHA, so it must be supplemented through your diet or meal in wild-caught seafood or a supplement such as krill oil. Various Americans are critically deficient in omega-3 fats, which mean they may be particularly susceptible to the harmful impacts of the excess fructose.
