Sugar makes our brain smaller! People who eat a lot of sugary and refined foods tend to lose brain volume over time. Other effects: brain fog, fatigue, increased excitability, decreased cognitive skills. And dementia. To avoid these troubles, you need to reorient yourself to other food in time. But how? Sweet addiction is comparable to drug addiction. In his book, Mike Dow, an expert on brain health, helps to properly assess the effect of sugar on the production of hormones in the body and suggests replacement therapy with other products to get out of the sugar addiction zone.
