How to Increase Intestinal Mucus

Your intestines have a layer of mucus that helps protect them from infections and inflammation. A deficiency in that mucus layer can increase your risk of bowel inflammation, upset stomach, diarrhea, and chronic conditions like colitis.^{[1]XResearch source} Naturally, you’ll want to support your intestinal mucus to improve your overall GI health. The best method is getting the recommended dosage of fiber, which you can do by following a healthy diet and taking supplements. In addition, follow some lifestyle tips to support your overall GI health.

1
Consume 25-38 g of fiber every day. Fiber is the main nutrient that helps maintain your intestinal mucus.^{[2]XResearch source} To keep your mucus layer healthy, consume the minimum recommended amount of fiber every day. That level is 25 g for women and 38 g for men. Try to get at least this amount from your diet or supplements.^{[3]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}
- Consult your doctor about developing the ideal plan for consuming more fiber if you have a deficiency.
- You can also work with a professional dietitian to design a proper high-fiber diet.
2
Eat fresh fruits, vegetables, and nuts for natural fiber. Instead of processed or prepared foods, choose fresh varieties of fruits and vegetables for the highest fiber dosage. Nuts like almonds, pistachios, and peanuts also contain high amounts of natural fiber. Include at least one serving of these foods in every meal to keep your fiber intake regulated.^{[4]XResearch source}
- The best vegetable sources for fiber are leafy greens like kale and spinach, beans, and peas.
- Berries, pears, apples, and ripe bananas are high-fiber fruits. Keep the skin on apples and pears for the highest dose of fiber.
- Frozen vegetables are also a good option for reaching your daily fiber level.

Switch to whole-grain products for an extra dose of fiber. White or enriched bread and pasta don’t contain as much fiber as whole-grain varieties. If you normally eat white bread products, switch to whole grain options for a boost in your fiber intake.^{[5]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}
- As a general rule, avoid white products. This usually means they’re bleached and enriched, which removes most of their natural nutrients.
- You can also incorporate more whole grains into your cooking. Quinoa, barley, oats, and brown rice are all high in fiber.
- Switch to whole-grain pasta as well. A serving of whole-grain spaghetti has about 6 g of fiber.
4
Use fiber-fortified cereals and bread. Some products have added fiber. Usually, these are grain products like cereals, bread, and oatmeal. Look for foods listed as “fiber-fortified” to get an extra boost.^{[6]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}
- Remember to still check the nutrition facts on these products. They may be listed as fiber-fortified, but have much less fiber than other natural products.
- Follow the serving recommendations for fortified products. They can cause an upset stomach or gas if you take too much.
5
Take fiber supplements if you don’t have enough in your normal diet. There are many supplements you can use to boost your fiber intake. Usually, they come in powder form. You mix the powder into a drink and swallow it all at once. Follow all the instructions on any product you use for the best results.
- Follow the dosing instructions on these products. Taking too much can cause gas and an upset stomach.
- Fiber supplements usually don’t interact with any medications but check with your doctor before you start using one just to make sure.
6
Consult a registered dietitian if your condition doesn’t improve. If you’ve made dietary changes and still don’t see the results you want, then you may be managing your diet incorrectly. Consult a dietitian for expert advice on designing and following a high-fiber diet. These professionals can help you achieve your nutrition goals.^{[7]XTrustworthy SourceMayo ClinicEducational website from one of the world's leading hospitalsGo to source}

1
Eat probiotic foods and supplements to keep your gut bacteria healthy. The good bacteria in your gut help keep harmful bacteria in check, preventing them from eroding your healthy mucus layer. Boost your number of healthy bacteria by eating probiotic-rich foods, or using probiotic supplements.^{[8]XResearch source}
- Probiotic-rich foods include Greek yogurt, kimchi, sauerkraut, miso, and tempeh.
- Make sure the supplements you take contain live cultures of bacteria. These are the most effective ones. Follow all dosing instructions on these products.
- You can also eat prebiotic foods, which feed the existing healthy bacteria in your gut. These include asparagus, whole wheat, artichokes, spinach, leeks, onions, and garlic.
2
Avoid foods high in saturated fats to prevent harmful bacteria growth. Just as probiotics help increase the good bacteria in your digestive system, saturated fats can increase your levels of harmful bacteria. Limit your intake of foods that are high in saturated fats to keep your gut bacteria balanced and healthy.^{[9]XResearch source}
- Red meats, processed foods, high-fat dairy products, cured meats, and poultry skin are all high in saturated fat.^{[10]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}

Exercise regularly to keep your GI tract healthy. Regular exercise helps move waste through your digestive system, maintains a healthy body weight, and increases the circulation to your digestive system. All of these keep your GI tract in good working order. Aim for at least 30 minutes of exercise 5 times per week to bring your intestines the nutrients they need to maintain a healthy level of mucus.^{[11]XTrustworthy SourceHarvard Medical SchoolHarvard Medical School's Educational Site for the PublicGo to source}
- Aerobic exercises like running, swimming, biking, and kickboxing classes are best for digestive health.
