Four theories why we consume sweet foods
and why it is so difficult for many people to live without sweets
Already our ancestors who lived as hunters and gatherer, included sweet berries and fruits in their daily diet. A good instinct was essential for survival following the general rule: „food that is sweet is not poisonous.” In addition, people who had access to energy-rich foods had a survival advantage over other people.
Fuel for our brain
Sugar is an important source of energy. Our brain needs a lot of energy because it is in a constant growth phase throughout life. Since carbohydrate stores are limited, concentration often deteriorates when blood sugar levels fall below a certain concentration. The uptake of energy in the form of sugar quickly helps to compensate this.
Sweets make you happy and lift the mood
With the uptake of sugar, tryptophan is transported into the brain. This amino acid is the precursor of the “happiness hormone” serotonin. It was verified, that the presence of this hormone-like messenger substance in our brain has a positive influence on our mood.
