Such anecdotes represent the significantly popular notion that we can heal our guts of whatever ails us by whittling down our diet plans to a bare minimum-- whether it's bone broth fasts, juice cleanses or plain elimination-type diets. Advocates of such programs declare that continuously processing "hard-to-digest" foods (frequently specified arbitrarily) trigger the gut to tiredness. As A Dietitian Is Not Impressed by J-Lo and A-Rod's 10-Day Diet Challenge , the gut requires time to rest and regrow. Another typical claim is that all sorts of health issues result from having too much "bad bacteria," and by starving them of carbohydrates, gluten or other dietary demons, the "excellent bacteria" can restore a grip and restore balance.
The Gut Microbiome
In fact, carbohydrate-containing foods that are challenging to digest for people are exactly what best fuel our gut's good bacteria. Similarly, by keeping carbs in general-- and fiber in particular-- we're most likely to starve the good germs than the bad ones.
In October 2018, I interviewed Daniel McDonald, Scientific Director of the American Gut Project at the University of California San Diego's School of Medicine. Based upon the lab's analysis of over 17,000 stool samples and the self-reported dietary routines of their donors, McDonald explained that the difference in the variety of the gut microbiome in between individuals who eat a great deal of individuals and plants who do not eat a lot of plants is higher than the distinction in between somebody who hasn't just recently taken antibiotics and someone who has.
Let that sink in: People who consume the fewest plant-based foods have actually such decreased variety and abundance of their gut microbiome compared to those who consume the most plant-based foods that the result of consuming a low-fiber diet plan is comparable to taking a round of antibiotics.
It makes good sense. Our gut germs feed on the complex carbohydrates we eat however can't digest, and various types of fiber and resistant starch feed different species and stress of these microbes. Foods that nurture helpful gut germs are called prebiotics. Far from taxing our intestinal tracts with too much digestive work, prebiotics really make our guts healthier and more durable by enriching the microbial community within.
