Researchers find that the Genetics links behind food intake, obesity, and diabetes could lead to improved prevention and treatment. The study examined how Genetics factors affect a person’s food choices and consumption, researchers have identified more than two dozen regions of sequences that may affect individuals’ food intake. The study was published in
Chloé Sarnowski, who was a biostatistician at Boston University while conducting the study and is now a faculty associate at the University of Texas Health Science Center at Houston said that the average daily intake of nutrients and foods, a major contributor of obesity, is partly influenced by our Genetics. Researchers say the brain is influenced by various signals that affect people’s eating behaviours and regulate their bodies’ energy balance. Those signals, for example, control appetite and energy expenditure in response to blood levels of key metabolic hormones and nutrients.
From that data, the team identified 26 Genetics regions associated with an increased preference for foods containing more fat, protein, or carbohydrate. In the brain, those genes influence specialized areas of brain cells, distributed across the central nervous system, that are responsive to proteins, fats, or carbohydrates. The discovery of these variants could be used in future research to determine whether diet composition is causally related to type 2 diabetes, obesity, and other diseases. The findings underscore why food consumption behaviour differs among individuals.
