Dietary Guidelines can not fully believe

We all know that an ice cream sundae makes a significant rise in your blood sugar levels. But a potato or a piece of toast it? A new study found that different people on their response to food intake is completely different, this research could perhaps help physicians rethink "one size fits all" dietary advice they provide.
"Before we think of obesity and diabetes are popular because people do not follow us out of the dietary recommendations." From the Weizmann Institute of Science in Rehovot computational biologist Eran Segal said, "When you see these data Later, you might start to think that maybe the problem is that they follow our dietary recommendations. "
Current popular dietary guidelines are usually based on the most people the most healthy food to develop. "Glycemic index" is the person eating the average rise in blood sugar after a specific amount of food. Dietitians by restricting carbohydrate intake people or keep them away from high "glycemic index" foods to control diet. But carbohydrates and the glycemic index does not accurately reflect how much food for the people affected.
In order to have a better diet and metabolic understanding, Segal and his colleagues studied 800 individuals metabolism, respectively, their blood components collected, anthropometric, lifestyle and gut microbes and other information. Blood sugar fluctuations and examined participants eat meals provided by the researchers and do their own meals in a week time.
To the researchers' surprise, different people react to the same or different glucose foods are not the same, although in the same period of time the individual responses to different foods is the same. The results are published in today's Cell top. The researchers used machine learning algorithm analyzes the data, and then developed into a system to predict how people will react to different foods.
Segal and his team used these findings to develop a diet plan 26 people, these foods cause food choices are based on the minimum and maximum amount of blood sugar rises in the body. High blood sugar appreciation and many chronic diseases are related, including type 2 diabetes. The varied diet, for a person of "good" diet for another man may be "bad" diet. According to forecasts, the "good" diet can balance the body's blood sugar levels, while the "bad" diet is to make them worse.
Nobody does not realize the uniqueness of the individual metabolic systems, "we know that a few decades ago because of individual differences, people rise in blood sugar levels will be inconsistent." From Boston Children's Hospital endocrinologist and nutritionist, said David Ludwig, "This provides a quantitative data of individual differences, but the starting point is not innovative." He himself did not participate in this study.
From the University of Leeds, UK diabetes expert Eleanor Scott said she was confident this customized diet tool. And Ludwig is different, different people different her reaction to food phenomenon is not surprising, because in everyday practice, she must fight with this difference. He said the customized diet may allow patients to be more motivated to stick to it, the disease might have a huge help.
"We know that different individuals vary response to diet, we are currently in a very blunt way to deal with this issue." Scott said that through the use of physical indicators, behavior, intestinal bacteria to predict the course of people handling food, the future Doctors may have a more effective treatment of metabolic diseases.
