What is the best way to improve gut health?

Eat the right foods.
“Americans’ fiber intake is 40 to 50 percent of what it should be,” Mullin says. A balanced diet rich in fruits and vegetables provides the fiber that builds good bacteria and gut health.

Other foods that build a healthy digestive system include kefir (a fermented milk drink that’s similar to yogurt and is rich in probiotics) and other fermented or pickled foods (such as kimchi, sauerkraut and pickled ginger).

Ask your health care provider about foods for specific problems such as constipation or bloating.

Get more sleep.
Not getting enough sleep is linked to a higher prevalence of obesity, which sets you up for digestive system disorders.

Move more.
As with other aspects of health, exercise is the best way to lose weight and maintain a healthy body weight to ward off digestive system problems.

Manage stress.
Reducing stress is fundamental to reducing heartburn, Mullin says. “There’s no magic diet that works.” Try relaxation therapies along with other distraction techniques.

Get help for issues like anxiety and depression.
Mood and digestive system health (especially disorders like irritable bowel syndrome) are closely linked via the brain-gut connection.
