In conclusion, these two outstanding studies support the fact that (1) it is not the quantity of calories per se that matters but the quality of the diet and (2) even in subjects of advanced age, adherence to a MedDiet is rapidly associated with different metabolic effects and reduced disease risk factors.
Mediterranean diet, gut microbiota and health: when age and calories do not add up!
According to Dr. Sadeghi, fiber-rich foods are generally enough to boost and maintain a healthy gut biome. While companies claim to have packaged the secret to digestion via fermented foods—such as yogurt, sauerkraut, kombucha, wine, and cheese—the truth is there is no recognized scientific evidence to support these claims. Dr. Sadeghi stated, “There are no studies which have actually looked at whether these probiotics get incorporated into the gut mucosa or get discarded into the stool. In fact, we don’t even know for sure they aren’t harmful. In a recent study published in Cell, researchers looked at whether probiotics get incorporated into the mucosa post antibiotic therapy to restore gut health. They did colonoscopies on two groups of individuals and samples their biome. Both groups received antibiotics. One group received probiotics and the other group did not receive probiotics. They wanted to know whether taking probiotics restored the health of the gut faster. To their surprise, the group that didn’t get probiotics recovered the biome faster!”
