When your body detects low food supply, it switches to a survival mode by using fructose to slow down your metabolism and store energy, so your brain gets more sugar.

Could Alzheimer's disease be a maladaptation of an evolutionary survival pathway mediated by intracerebral fructose and uric acid metabolism?

Narrative Review

2023 Mar

This study says that when your body processes fructose (a type of sugar), it acts like it’s in a famine — slowing down your metabolism, storing fat, and saving sugar for your brain. That’s exactly what the claim says, so the study supports it.

Similar Assertions

Eating fructose (like in sugary drinks) might be worse for your body than eating glucose (like in bread), because it can lead to more harmful fat buildup, insulin problems, and higher uric acid — all of which could increase your risk of heart disease.

Eating too much fructose, like the sugar in soda and candy, can mess up your liver’s ability to respond to insulin, make more fat in your liver, and raise fat levels in your blood, which can lead to bigger health problems like heart disease.

Eating too much fructose—like the sugar in soda and sweetened snacks—may slow down your liver’s ability to burn fat, which can lead to fat buildup and make your body less responsive to insulin.
