Question

Why do nutritionists and psychiatrists say sugar is poison for the brain & body? What does it do?

In: Biology

Answer 1

Sugar is fuel, not poison Each cell in our body uses sugar and oxygen to function. Plants make sugar from sun, water, and CO2.

Plants store sugar as sugar or as more stable carbs. Our body breaks down carbs into sugar, but we also get vitamins, minerals, protein, etc. from the food we eat. If you eat too much sugar and bypass the rest of the food, you get energy but not much else.
