Fermented preserved food

How’s your gastrointestinal system feeling these days? From the incredible science of the microbiome to general tummy troubles like gas, bloating, constipation, diarrhea and pain – the role and health of the ‘GI’ system is on everyone’s mind, especially during the eating-holidays of fall and winter. There are some common denominators to keeping the gut happy. Fiber, anti-inflammatory foods, and soothing substances top the list of 50 foods that support the GI system. Whether you’re feeding the gut with prebiotics, inoculating it with probiotics or simply feeding it to make it work smoothly, you should include these foods in your diet today.

Detox activated charcoal black chia lemon water

Charcoal is popping up in supplements and on menus because of its intriguing potential health benefits. Thought to bind with toxins in the gut, you should use caution with this one because, though there are some promising outcomes, it may possibly cause or worsen constipation and can also bind with nutrients your body needs. When using it as a targeted treatment, it can help soothe the gut, keeping it healthy when traveling.

Aloe Vera Leaves

A top gut soothing herb, aloe works on the digestive tract like it does on the skin for a sunburn. Its viscous fibers coat the gut and create a soothing barrier during times of irritation. Use caution because aloe can block the gut from absorbing the nutrients it needs in food so using it short term as needed is generally best.

Fresh homemade applesauce with apples

Ever heard of the “BRAT” diet for an upset stomach? Bananas, rice, applesauce and toast are bland foods that help heal the gut and return it to optimal health. Apples are a rich source of soluble fiber and in blended form, are generally very well tolerated, giving the gut a little rest. If you’ve got tummy troubles, reach for some unsweetened applesauce right away.

The leader of the “BRAT” protocol, bananas are another high fiber, soft, soothing food for the stomach during times of irritation. Bananas make a good binder and, though they can cause constipation for some people, they’re fantastic for treating diarrhea or loose stools. Bananas are a perfect grab-and-got snack and also contain electrolytes like potassium to keep your system running smoothly.

Fresh garden basil herbs in mortar

Herbs like basil are full of soothing antioxidants for the gut. Fresh or dried basil has been shown in animal and human studies to reduce gas, bloating, constipation and diarrhea. The reason basil helps the GI is likely because it decreases the production of stomach acid and calms histamine receptors.

Beans sometimes get a bad reputation for the gut – in some people they can cause gas and bloating. This is often because people aren’t used to the high amount of fiber that beans provide. Black, pinto, cannellini, kidney, chickpea and beyond, all beans are healthy for the gut and packed with vitamins, minerals, antioxidants and fiber to keep you regular. To increase the digestibility of beans, increase them slowly over time in the diet. Use a seaweed like kombu when cooking beans and always rinse of the liquid in canned beans.  

Oat bran

There’s a reason bran is considered a health food – including it in hot or cold cereal, blended into pancakes, waffles or muffins keeps the gut running smoothly. Bran is a whole grain high in fiber and nutrients. It keeps the digestive tract moving along smoothly for proper regular elimination and it also provides fuel for the good bacteria living in your colon. These bacteria make vitamins for our bodies and may even play a role in brain health, the immune system, weight and inflammation.

Halves of raw organic butternut squash with spices and ingredients for making

Squash is a high fiber vegetable full of water, vitamins, minerals and antioxidants that can be incorporated into your diet to support gut health. All varieties of squash contain a high content of antioxidants lutein and zeaxanthin which calm inflammation and irritation in the body and butternut squash in particular is packed with beta-carotene, commonly found in orange-colored veggies. Turn it into a stomach soothing soup by roasting then blending with broth and calming herbs and spices until smooth.

The orange color of this melon immediately tells you it contains carotenoids like vitamin A for anti-inflammatory support. It’s also full of vitamin C and fiber to decrease inflammation and support regularity and healthy elimination habits. Cantaloupe can help ease constipation.

Brown wooden spoonful of chia seeds

If you’re looking for fiber to support the gut, chia is where it’s at. Tiny chia seeds offer 5 grams of fiber per tablespoon. A chia pudding or smoothie can get you nearly half the fiber you need in a day if you add 2-3 servings. They also offer a source of protein and omega-3 fatty acids which offer anti-inflammatory properties to help soothe the gut.

Hot chocolate in the cup

11. COCOA 
While the fat and sugar in a chocolate treat can be irritating to the GI system, unsweetened cocoa powder can help it by calming inflammation. Cocoa contains more phenolic antioxidants than most foods. Flavonoids including catechin, epicatechin, and procyanidins are dense in this bitter powder. Get creative by adding cocoa to smoothies and low-sugar recipes where it’s natural bitterness and complexity shine through.

Freshly opened coconut drink with straw

If you’re experiencing fluid loss from diarrhea or vomiting, you need to get your hands on some coconut water. Rehydrate with the natural fluid content of coconut water plus electrolytes like sodium and potassium. Rather than added sugars, color and flavor in other sports rehydration beverages, coconut is all natural. Make sure to choose an unsweetened variety.

Cup of coffee with smoke and coffee beans on black background

Though the acidity in coffee can irritate conditions like gastritis or GERD/acid reflux, it can also help with healthy bowel movements in the morning. The caffeine combined with the warmth of the liquid helps stimulate elimination in the morning for many people. Coffee can be a great natural, no calorie, gut support. Just be sure not to load it up with cream and sugar which are both irritants.

Raw Organic Red Dandelion Greens

There’s one critical piece of digestion that must be supported; the liver and gallbladder. Without these working properly, the body can’t get bile into the stomach to digest food. If the gallbladder has been removed, the liver can pick up the slack, but if you have a gallbladder, you’ll want to support it with bitter greens like dandelion. The greens of this common flowering weed are known for enhancing detoxifying activity in the liver. If you can’t get your hands on the fresh greens, feel free to include dandelion tea in your diet for similar benefits.

raw organic fennel Seed

If you’ve got an upset stomach, make sure to immediately reach for fennel seeds. Proven to calm the upper GI system, these tiny seeds flavored like anise calm nausea and settle the stomach. They can make a wonderful end to a rich meal or can be used on their own in times of stomach troubles.

Ginger root and ginger powder in the bowl

A well-known root that calms the stomach and relieves nausea, ginger is a must-have for your medicine cabinet. It’s naturally spicy flavor can be used as a chew, infused into a beverage such as water or tea, or grated into a variety of recipes ranging from cereal and dessert to stir-fry, marinades and dressings. Sniff some ginger or chew on some to calm an upset stomach when ill, pregnant, traveling, or undergoing medical treatments that cause nausea or vomiting.

Green tea n the brown mat

The ultimate antioxidant beverage, green tea contains powerful compounds called catechins and amino acid L-theanine. These compounds target relaxation and the reduction in stress which can help support the GI system. Better yet, like coffee, unsweetened green tea can act as a stimulant in the morning to get the gut going and start the day off right with healthy elimination.

Honey in jar and bunch of dry lavender

This natural sweetener contains some gut soothing properties in addition to its wonderful flavor. There’s a reason that mixing honey into tea is comforting; raw honey is a source of prebiotics that help fuel the gut and feed the good bacteria that live there and help many systems in the body.

Turmeric Lassie Drink

Have you seen this fermented dairy beverage in your yogurt aisle? Luckily, kefir is gaining in popularity along with other fermented foods that are known to feed the good bacteria in the gut. Did you know that we have more bacteria living in our guts than there are human cells in the body? This massive system benefits from diversity of bacteria so when we introduce other good bacteria from fermented foods like kefir, it can be a big benefit. When looking for kefir, just like yogurt, make sure to choose a lower sugar variety.

The dried sea vegetable kombu should be in your kitchen cupboard for use in soup and bean dishes. Using even a small strip of kombu can increase the digestibility of bean dishes when used during cooking. It also infuses in a variety of vitamins and minerals to any dish it’s added to, so use this versatile seaweed to maximize nutrients and increase that umami flavor in soups and stews.

Group of fresh lemon on an old vintage wooden table

Not only is lemon a potent source of antioxidant vitamin C, it also stimulates the liver and gallbladder for proper function and digestion. If you need a boost in the morning that accompanies hydration, drink a cup of warm water with lemon added. You will ready your digestive system for the day and may even stimulate a morning elimination to keep you regular.

Production steps of licorice, roots, pure blocks and candy.

Deglycyrrhizinated licorice, called DGL, is used before meals to treat reflux and stomach upset. Some of the best evidence for using licorice is for conditions of the stomach and digestive system. It also has been shown to provide anti-ulcer and anti-viral support in studies. Next time you’re feeling stressed or have an upset stomach, licorice could be just the thing that helps.

Similar to other bitter greens like dandelion, mustard greens are packed with compounds that stimulate digestive enzymes and support the stomach.

Bitter compounds in food are stimulating to liver function and contain the nutrients needed for both phase 1 (activation) and phase 2 (elimination) detox.

Oats with ears of cereal

30. OATS
Oats are a whole grain that contain gut-supporting fiber. Another source of beta-glucans, like mushrooms, oats contain compounds that boost the immune system and ward off disease and illness.

One of the richest fruits in fiber, one medium-sized pear contains 6 grams. In comparison, a serving of Metamucil powder only contains 2.4 grams of fiber. Eating the skin of a pear is important because it contains a large amount of the fiber in this fruit. Swap out an apple or orange for a pear instead for an on-the-go snack that can help keep you regular.

tea with peppermint

A well-known digestive aid, peppermint oil and tea are regularly used to calm stomach muscles and improve the flow of bile from the liver to support digestion. Keep in mind that peppermint can actually worsen the symptoms of heart burn or gastric reflux so work with your doctor or dietitian to use this correctly.

Sweet potatoes

In studies, the starch in sweet potatoes has been proven as a slowly digestible fiber that supports gut health. Sweet potatoes contain calming vitamin A and lycopene for anti-inflammatory properties.
