INCREDIBLY OFFENSIVE, SUGAR.
Some of the most obvious and recognizable signs of a sugar rich diet are our ubiquitous large paunches and the ever increasing number of obese people around us. The more covert effects of too large a consumption of sugar are a negative effect on our organs, minds, brain and psyche; damaging our nerves and thus impairing our cognitive function, memory and psychological well-being.
Why then, do we continue to swallow copious amounts of sugar laden foods? Those endless bouts of comforting chocolates, ice-creams and all the no-no foods doctors always warn us against.
Most tastes are accepted or rejected almost immediately on entering the mouth. Bitter, sour, salty, savory, spicy, all have receptors on the tongue alone. But sweet! We are not the only ones to favour sweet. Nature too gives it two sets of receptors instead of one.
UNLIKE WITH OTHER FOODS, sugar has special receptors in the stomach and the intestines which signal to the brain (stem & cerebral cortex) that one has eaten enough. These also inform the brain if the body needs further secretion of insulin.
The cerebral cortex processes the taste of the food and signals the brains reward system which informs the body whether it would like to repeat the experience. Sugar gives a good feeling; the body decides to repeat the experience.
In The brain there is dopamine, a neurotransmitter (chemical messenger). The main functions of Dopamine are in movement, memory and pleasurable rewards. It is also a precursor to substances like adrenalin. This dopamine spikes when we do things that we enjoy and can trigger addiction by causing our body to crave more.
The dopamine syndrome explains why we tire of good wholesome home cooked meals but can continue to eat that delightful chocolate cake and cheesy pizzas for weeks on end.
