You Will NEVER EAT Sugar Again After WATCHING THIS! | Dr. David Perlmutter

Eating sugar gives your brain a huge surge of a feel-good chemical called dopamine. That explains why you’re more likely to crave a candy bar at 3 p.m. than an apple or a carrot.
Because whole foods like fruits and veggies don’t cause the brain to release as much dopamine, your brain starts to need more and more sugar to get that same feeling of pleasure. This causes those “gotta-have-it” feelings for your after-dinner ice cream that are so hard to tame.
Your Mood
The occasional candy or cookie can give you a quick burst of energy (or “sugar high”) by raising your blood sugar levels fast. When your levels drop as your cells absorb the sugar, you may feel jittery and anxious (a.k.a. the dreaded “sugar crash”).
