What probiotic strains help with the digestion of proteins?

Quite possibly, none. Protein digestion begins in the stomach, with acidic hydrolysis (breaking apart by water) and enzymatic cleavage of protein peptide backbones. Protein-degrading enzymes are also abundant in the upper small intestine, which has a relatively low level of bacteria. By the time proteins get to the large intestine, where most of our bacteria Read More …

Isn’t the whole reason for cooking our meat to kill bacteria? Shouldn’t washing it before cooking eliminate bacteria?

Cooking is an old and universal practice. It certainly is much older than germ theory (which was developed in the 1870s), so for most of the history of cooking, the rationale could not have been to kill germs. Fresh meat, particularly wild game, will not have much of a bacterial load, and cooking it would Read More …

How far are we from having our bacteria engineered to reduce obesity?

Not far at all. The principal barriers to implementation are regulatory rather than technical. But prepare to be underwhelmed by the results. Most of the action in applying the insights of microbiomics to obesity and related metabolic disorders has come in the form of probiotic (“good” bacteria) or prebiotic (compounds that favor the growth of Read More …
