Weizmann Scientists Can Use Data about How the Body Responds to Specific Foods to Create a Diet Tailored to You

The food we eat affects our health and well-being but how? One of the key ways is by changing our glucose levels. Glucose, commonly known as blood sugar, is the primary source of energy for the cells that make up our muscles and other tissues. In people who are overweight or obese, high blood sugar levels can cause a rise in insulin levels, leading to fat storage. High blood sugar levels are also associated with a number of serious health problems, such as diabetes, heart disease, stroke, and cancer.

However, people have different metabolic responses to the same or similar foods. For example, two teaspoons of sugar in your morning coffee could mean the same thing in metabolic terms fat storage as one teaspoon of sugar for your officemate. That's why a diet won't necessarily provide the same results for everyone who tries it, even if they are eating the same foods and exercising the same amount. Recent theories suggest that this variability across individuals may be explained, in part, by differences in their absorption and processing of different types of simple sugars. This absorption takes place mostly in the small intestine, thanks to the hard work of a vast array of microbes a group collectively referred to as microbiota.

At the Weizmann Institute of Science, Prof. Eran Segal of the Department of Computer Science and Applied Mathematics and the Department of Molecular Cell Biology and Dr. Eran Elinav of the Department of Immunology are launching a project that is expected to provide many insights about the function of the microbiota and their role in glucose absorption on a personal level. In the experiment, over the course of ten days, the scientists are monitoring the glucose intake and absorption of hundreds of subjects and the activity of their microbiota. They are collecting data using several methods, including a glucometer that is attached to the subjects' bodies. Subjects can see their own blood sugar levels rise and fall throughout the day in reaction to the foods they eat. Using that data, the scientists will develop algorithms to predict individuals' personal response to a wide variety of foods. Subjects will receive access to a web site with these predictions, a profile of their own gut microbes, an analysis of how the microbes affect blood sugar, and a nutritionally balanced diet tailored just for them.

Prof. Segal and Dr. Elinav each bring unique expertise to the study, known as the Personalized Nutrition Project. Prof. Segal, a mathematician and cell biologist, develops computational models aimed at understanding how molecular components interact to carry out complex biological functions. An immunologist and an MD, Dr. Elinav is focused on understanding inflammatory bowel disease and investigates the microbes of the gut.

They hope the Personalized Nutrition Project will provide the first-ever comprehensive profile of the small intestine's microbiota, as well as the first tool for predicting individualized glucose response to complex meals. It could pave the way for designing customized, balanced diets based on scientific data about each person's microbial makeup. "If successful, our study may allow us to move from empirically based to personally based nutrition, and thus to personally tailored medicine," says Prof. Segal.

This just might become the only diet that really works for people. The huge amounts of money people spend to lose or in some cases gain weight are generally very unsuccessful, but this is looking each individual and their sugar up take. That is a sound medical way to begin the process of losing weight. Thanks J L

I'm thinking it won't replace food allergy testing - but it may lead to more food allergy testing - if they get enough data and the data starts to show reactions to food that are strong enough to indicate possible allergies. Food allergies, if you have them, definitely play a role in weight; not only in sheer numbers but in what the weight is composed of (with food allergies it's often fluid).

You are welcome Kit. Thanks for the insights related to weight management Kit and for food allergies Joanne.
Star headed your way Joanne, I'm told it is too soon for you Kit.

It would be great if everyone could afford to get this done. There are way more reasons for people being over or under weight than the amount of foods or the calories they take in, and it all has to do with how your body metabolizes what you eat. As this says, no body will take in and utilize the same foods exactly the same. Thanks

For now, true Marianne. Once it is beyond the research phase, health professionals all around the world will be able to do for people. You cannot currently send a star to Marianne because you have done so within the last day.

This research sounds very promising, and also it's really interesting. The whole area of microbiota is a developing area of study, yielding fascinating and useful findings. Thanks J.L.
