The temptation to resist the sweets is no longer the fault of the girl. The British “Daily Mail” published today that the new study found a scientific basis for girls who love sweets. Their behavior was caused by a special gene.
The Michael Minni team at McGill University in Montreal tested more than 150 children and their mothers. Canadian researchers have found that obesity is the result of a combination of genetic defects, environmental stress, and mental health.
Helping girls control the genes released by dopamine, making them unable to resist the temptation of sweets. The number of dopamine receptors is related to human genetics, lifestyle, and external stimuli. The dorsal striatum of the brain releases the neurotransmitter dopamine as a response to eating, and the amount of dopamine released corresponds to the degree of pleasure that food brings.
In obese girls, the dopamine response appears to be slower due to fewer dopamine receptors in the body, causing them to eat too much to compensate for the decline in pleasure. According to brain imaging technology, the dorsal pattern of obese girls is less active. Those who carry the A1 striatum dopamine D2 receptor gene are the slowest to respond to sweets such as milkshakes.
Professor Minnie added that during the large number of snacks test, the study also found that genetic and mental health is also the reason for people to increase their appetite and ultimately lead to obesity. Therefore, the next step is to identify girls with such problems in anticipation of early prevention and intervention in obesity.
