Most people know that sugar is not good for them, but the risk is less known.
Sugar is just as much of a silent killer as salt. Excess fructose consumption was linked to leptin resistance, a hormone that tells you when you've had enough food. It all happens without symptoms or warning bells.
When glucose is present in the body, the pancreas releases insulin, causing the cells of the body to absorb sugar from the bloodstream. Through this absorption, the molecule tryptophan, the sleep-inducing culprit of Thanksgiving dinner, is converted into serotonin, the “happiness molecule.” It’s only in severe cases when the bloodstream is completely overloaded with glucose that insulin works too quickly and results in a sugar low, [ hypoglycemia]. Quite the opposite of a sugar high, hypoglycemia will leave you feeling sad, fatigued and in some cases depressed.
Too many calories from any source will be stored as fat if not burned, but the lack of other nutrients in sugar makes it much easier to eat gobs of it with no physical effects to warn of the danger that lurks. That's why you can have an entire king-size bag of licorice at the movies and come out ready to go for dinner. Foods rich in fiber, fat and protein all have been associated with increased fullness
Simple sugars coming from fruit are less concerning given their high amounts of disease-fighting compounds and fiber. Just a thought.
