Study of the Universidade Estadual Paulista (UNESP) showed that genes influence metabolism have the feeding behavior of adolescents.

The research evaluated the effect of the combination of these polymorphisms, or variations, with the lifestyle and examined the influence of this association with risk of chronic diseases such as diabetes, obesity, hypertension and high cholesterol.

According Emilia Alonso Baltazar, author of the study, the group of young people with polymorphisms in the genes studied, around 30% had abnormal levels of lipids or fats in the blood called dyslipidemia.

From the epidemiological point of view, this work explains why some groups are more susceptible to environmental factors. For example: A skinny teen may have high cholesterol, indeed unthinkable to lay, or the fact that some young people do not respond well to treatment based on diet or physical activity.

According to the author, the warning for the existence of genetic metabolic disorders in adolescents occurred in his Masters, completed in 2008, when it was found a large number of adolescents with abnormal lipid profile, not explainable by environmental and physiological factors. For this reason, we have assumed that there could be other variables influencing these changes, such as genetic, explains.

She made a biochemical analysis in insulin, glucose, triglycerides, total cholesterol and fractions, and apolipoprotein APOA1 related to polymorphisms linked to the development of cardiovascular disease. Blood samples were collected from 214 children in Piracicaba (SP), including rural residents, aged around 11 years.

Coupled with biochemical sampling, the researcher also sought to identify possible changes in the chain of genes involved in lipid metabolism, responsible for the processing of fat that circulates in the body.

Dysfunctions in metabolism can result in cardiovascular disease, obesity, hypertension and diabetes.

The researcher suggests diets and physical activity practices directed to the genetic profile of adolescents to prevent the development of metabolic risk factors and the onset of chronic diseases in adulthood. But a diet to prevent or combat chronic diseases can not be generalized.
