One topic that was not mentioned in the article that I have found fascinating is that your gut microbiome can actually affect your cravings. (1) Your microbiome accomplishes this through a host of mechanisms including changing the expression of taste receptors, making certain foods taste better; they may release hunger-inducing hormones; or they may manipulate the vagus nerve (which connects the stomach to the brain)…
But i'm not saying that there is no such thing as the microbiome directly influencing your brain, bacteria produce a wide array of by-products. In which way these by-products affect our bodies is exactly the question. I just want to point out that there are types of dysbioses that can reduce the ability to absord certain nutrients and by that could exacerbate the problem of cravings.
