Diet books and diet gurus, they are all useless. Each organism reacts differently to food, so there is no general diet that is subject to a large study. Even twins do not enjoy the same diet.
"Everyone has a unique way of digesting food, which is one of the reasons that medium-based universal diets often miss a goal," said lead researcher Tim Spector, a professor of genetic epidemiology at King & Co. # 39; s. College London c. From Morgen.
He has just presented the first results of the most comprehensive survey on the subject. The researchers described the first results of their large study of 1,100 British and Americans, 60% identical twins, as "surprising and even shocking".
The team studied blood glucose, insulin, and blood fat levels after specific meals. The rhythm of sleep, physical activity, body fat and microbiome (the many microorganisms such as bacteria, viruses and yeasts in our intestines) have also been mapped with the help of tests, Samples and monitoring 24 hours a day.
People have a blood sugar spike after having, for example, eaten a muffin with a lot of sugar while others reacted to the same meal with a greater amount of fat in the blood. The first reaction was associated with an increased risk of weight gain and type 2 diabetes, the second with an increased risk of cardiovascular disease. Same food, different consequences.
"To our surprise, we saw this even with identical twins," says Spector. For example, one twin reacted after a sugary drink with a blood sugar spike two times higher than the other. And after a bag of fries, the researchers got a peak of triglycerides (fats in the blood) six times higher than in the other
. Researchers have a strong chance that environmental factors such as sleep, stress, exercise, and our hyperindividual microbiome will differ.
Lesson: If a diet works for your neighbor, it may be useless for you.
