Eat a custom fiber plate.\u003C\u002Fstrong> Dietary fiber is the microbiome's food. Healthy adults should aim for \u003Cstrong>25–30 grams of fiber daily\u003C\u002Fstrong> — roughly 500 g of vegetables, 200 g of fruit, and 50 g of whole grains — with dark-colored vegetables preferred. Raw bananas and refrigerated cooked potatoes are rich in resistant starch; konjac flour and inulin act as prebiotics. Diabetics can add konjac, oats, and other low-glycemic foods to stabilize blood sugar and suppress harmful bacteria. Note: people with liver disease, chronic diarrhea, the elderly, and children should avoid high-fiber diets. Also avoid high sugar, fat, and salt, and quit smoking and alcohol.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cimg src=\"\u002Fattachment\u002F20261005\u002F0791d7b6e2e44bfa846ed22b59937d37.webp\" alt=\"img_04.webp\">\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>2. Move to activate.\u003C\u002Fstrong> Exercise promotes gut motility and keeps the gut environment \"clean and comfortable.\" Aim for \u003Cstrong>150 minutes per week\u003C\u002Fstrong> of moderate-intensity activity like running or brisk walking; cut sitting time, and stand up for 5 minutes for every hour seated.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>3. Keep a regular schedule.\u003C\u002Fstrong> Gut motility and its microbes have developed their own biological clock through long coexistence with the body. Irregular sleep and chronic late nights disrupt the flora and gut function — the most obvious signs: bad breath and constipation in many night owls. Sleep before 11 p.m., fast for 1 hour before bed, and keep meals regular within a half-hour window.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>4. Don't let negative emotions pile up.\u003C\u002Fstrong> Prolonged stress, anxiety, depression, and other negative states easily disturb gut function. The gut, in turn, impairs cognition and sleep, worsening the mood problem. Learn to decompress: stay in good spirits and take time for meditation.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>5. Get daylight.\u003C\u002Fstrong> Sunlight boosts serotonin synthesis, with an immediate effect on mood.
