Health system Individualized diet
An individualized diet based on a person’s genetics, microbiome and lifestyle is more effective in controlling blood glucose (sugar) levels than one that considers only nutritional composition of food, researchers have confirmed. The research published on Feb. 8, demonstrates that each person’s body responds differently to similar foods, due to the unique composition of each person’s gut microbiome — the complex community of trillions of bacteria within the digestive tract. The study finds that an individualized approach taking into account each person’s gut microbiome, age, diet, physical activity and other factors more accurately predicts blood glucose levels than carbohydrates or calories of the food “The standard approach of counting carbohydrates and calories does not work as well because it considers only the characteristics of food. It fails to factor in the unique microbiome and lifestyle of each person,” says lead author on the study.. It sheds light on why some people can eat foods like fruit and feel energized, while others eat fruit and experience a blood sugar spike that eventually makes them feel tired. Glucose, which comes from the foods eaten, is the main source of energy for the body. Controlling blood glucose — the amount of sugar in the blood — is important to preventing disorders such as diabetes, heart disease, obesity, vision loss and kidney disease.
