”I would rather have a shorter life with cigarettes than a longer life without. Well, that's addictive thinking. You see the dominance of the addictive brain cells in that line of reasoning. That's not frontal lobe dominance. That's the addicted brain cells. And that's why addictions are lethal.” No matter what your relationship to food is, we all live in a world manipulated by an addiction business model. We’re constantly confronted with ads for foods that have been designed to make us want more, and it began when the tobacco industry started buying up brands like Nabisco and...

As a person with diabetes, keeping your blood sugar levels within the range recommended by your doctor can be...
