Mechanisms underlying gut microbiota’s role in obesity

Energy absorption and short-chain fatty acids

Gut microbiota regulate energy metabolism through short-chain fatty acids (SCFAs) like acetate, butyrate, and propionate, which are products of fiber fermentation. While butyrate promotes insulin sensitivity and reduces inflammation, propionate may trigger overeating. Dysregulated SCFA production can contribute to obesity by enhancing energy absorption, disrupting appetite regulation, and promoting fat accumulation. Recent findings suggest that modulating SCFA production through dietary interventions can help regulate energy balance and improve metabolic health. Maintaining SCFA balance through diet or microbial modulation holds promise for obesity management.

It’s become increasingly clear that the gut microbiome can affect human health, including mental health. Which bacterial species influence the development of disease and how they do so, however, is only just starting to be unraveled.

For instance, some studies have found compelling links between one species of gut bacteria, Morganella morganii, and major depressive disorder. But until now, no one could tell whether this bacterium somehow helps drive the disorder, the disorder alters the microbiome, or something else is at play.

Harvard Medical School researchers have now pinpointed a biologic mechanism that strengthens the evidence that M. morganii influences brain health and provides a plausible explanation for how it does so.

“ tabindex=”0” acid UDCA can regulate tumor growth in mice with liver cancer. This discovery suggests that UDCA dietary supplements could offer a fast and effective way to improve outcomes for liver cancer patients.

Immunotherapy is an advanced cancer treatment that harnesses a patient’s immune system to target and destroy tumors. It has significantly improved outcomes for various cancers, including those of the lung, kidney, and bladder. However, its effectiveness against liver cancer has been notably limited—a concerning issue given that liver cancer rates have nearly tripled over the past 40 years.

The rising trend of early-onset cancers in adults under 50, particularly women, is alarming. Genetic, lifestyle, and environmental factors contribute to this increase. Maintaining a healthy weight, quitting tobacco, avoiding alcohol, consuming fiber-rich foods, using sunscreen, and regular physical activity are small lifestyle changes that can significantly reduce cancer risk.
