Genetic Differences Found in People with Identical Diets

An Israeli research monitoring the levels of blood insulin in more than 800 people for several weeks indicated that when a group of individuals consumed the same foods, how they are assimilated differs from one subject to another. All results, released this week in medical journals, illustrate the importance of customized nutrition in assisting individuals to see which foods will help or restrict their own wellness objectives.

Blood sugar and insulin has a tight connection with health issues, such as diabetic complications and being overweight, and it is simple to measure it by using a consistent glucose tracker. A test developed many years ago, the glycemic index, is applied to position foods depending on how their ingredients influence blood sugar levels. This is an element used by physicians and dieticians to create healthy diet plans, but the program originated from analysis that average the way in which limited groups of individuals tolerate various foods.

This new research, led by Israeli scientists, discovered that the glycemic index of different foods are not set values, but rely upon the person that is tested. For all members, they gathered information through health surveys, body dimensions, blood tests, sugar monitoring, feces samples and mobile applications used to review lifestyle and individual diets. In addition, all volunteers obtained a few standard and similar foods for their meals.

As predicted, age and BMI were noticed to be linked to sugar levels after eating the scheduled meals, this result being identical to previous analyses performed on large groups of individuals. Besides this, the collected information also showed that different individuals have very different reactions to similar diets, even if their personal habits were not modified during the research.

Most nutritional suggestions met in the popular culture are depending on some of these rating systems, but what they do not emphasize or probably do not take completely into consideration is the important variations between people. In some instances, some subjects had opposite organic reactions to another person, and this represents a big gap in the literary works, according to the specialists who have conducted these tests.
