A recent report from the University of Dundee, Great Britain, which conducted a power test to 100 school-aged children aged 4 to 10 years, concludes that the appeal of foods with higher fat and sugar is genetic.
The results were overwhelming: children who have the "obesity gene" consume 100 extra calories in one meal.
They prefer foods with fat and sugar, instead of other healthier options.
According to researchers, the obesity gene is present in 62% of the population.
Beyond what the British researchers discovered, other factors also influence the type of foods we are attracted to, foods high in fat causes a great sense of delight in the mouth and hold the taste of food.
When you stop eating fat, in a sense you have lost that good feeling, and unless you replace other foods that have a interesting taste, the food will never taste the same.
Moreover, the meal that contains fat has a high level of satiety (the body takes longer to digest than protein or carbohydrates).
Not all people quench their desire for "something good" with foods high in fat or sugar.
Some people are satisfied with a pineapple, which is very sweet, or a banana.
However, many people associate "sweet" with baked goods or candy, because the palate is adapted to the sweetness that comes from added sugar.
It's conditional and may change with constant effort, but it will not be easy.
There are people who crave a fruit or a vegetable for moisture, texture and flavor.
If one intends to eat more and more of this kind of food instead of less healthy food choices, little by little, it too will become unhealthy.
High-calorie carbohydrates promote the production of serotonin in the brain.
Serotonin is the neurotransmitter of feeling that makes you "feel good".
This sends a chemical messenger of satisfaction and calms the brain.
This process is triggered when you eat high-fat carbohydrates.
It does not work the same way with fruits and vegetables.
