Doctors Highlight Diet, Stress Links to Gut Health

Research suggests gut health is connected to broader health: the gut microbiome can influence nutrient absorption, inflammation and metabolism, while muscles also send signals that affect the gut. A review highlights fermented foods such as kefir and yogurt as a possible way to support both gut and muscle health, though the evidence does not establish them as a guaranteed benefit. Gastroenterologists also recommend everyday habits such as eating more fiber and a variety of plant foods. Because stress can affect digestion and bowel habits, one gastroenterologist suggests physiological sighs, muscle tensing and release, and humming-based breathing as practical stress-management techniques. Separately, studies have linked higher ultra-processed-food consumption with increased colorectal cancer risk, underscoring the potential importance of diet quality.
