Hundreds of bacterial species live in the human gut, helping to digest food. The metabolic processes of these bacteria are not only tremendously important to human health – they are also tremendously complex. A research team at the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg has taken an important step in modelling the complexity of the human gut's bacterial communities – the microbiome – on the computer. The researchers gathered all known data on the metabolism of 773 bacterial strains – more than ever before. Working from this data, they developed a computer model for each bacterial strain. This collection, known as AGORA, can now be used on the computer to simulate metabolic processes taking place in the microbes and to investigate how they affect the metabolism of other microbes and that of the human host. The LCSB team publishes its results in the scientific journal Nature Biotechnology. The collection of predictive metabolic models is available to researchers via vmh.life.
The bacterial species living in the human gut not only help to digest food, but also produce valuable vitamins and even affect the way we metabolise drugs. The metabolic processes of these bacteria are crucial to health, and are highly complex: The bacteria are in constant contact with gut cells, and the different organisms continually influence one another. Thus, they play as important a role in health as they do in numerous diseases. Despite many advances in science, knowledge of these microbes is still limited. To improve understanding and to aid novel discoveries, the research team led by LCSB scientist Prof. Dr. Ines Thiele, head of the "Molecular Systems Physiology" group, has now created the most comprehensive collection of computational models for 773 different gut microbes, capturing their individual metabolisms, called AGORA. "AGORA is based on a new concept for the comparative reconstruction of bacterial metabolic models," says Ines Thiele: "It allows the analysis of a much greater number of bacterial strains than was ever possible before. With AGORA, and by including other datasets, we can systematically study the metabolic interactions within the gut microbiome and how these interactions are influenced by external factors, including the diet and host metabolism."
Thank goodness for AGORA. Eating a bad egg-salad sandwich didn't help.

That is absolutely correct. There are basically 2 kinds of studies:
A. "$FOOD_PRODUCT is a miracle that will help you lose weight, cure cancer, and be healthy forever without having to change behavior!" This is, of course, funded by the $FOOD_PRODUCT industry.
B. "$FOOD_PRODUCT is terrible for your health, leading to cancer and other terrible illnesses regardless of any other factor!" This is, of courses, funded by the industry that most heavily competes with $FOOD_PRODUCT.
Sometimes, you'll get both of these at the same time.
Understanding what is really going on would be fantastic. But nobody does, and the various $FOOD_PRODUCT industries take full advantage of that to fund studies that benefit themselves. And since nobody who isn't connected to the food industries has enough funding to conduct a study, this kind of nonsense is all we ever get.
