Back Clinic Gut and Intestinal Health. The health of an individual’s gut determines what nutrients are absorbed along with what toxins, allergens, and microbes are kept out. It is directly linked to the health of the whole body. Intestinal health could be defined as optimal digestion, absorption, and assimilation of food. But this is a job that depends on many other factors. More than 100 million Americans have digestive problems. Two of the top-selling drugs in America are for digestive problems, and they run in the billions. There are more than 200 over-the-counter (OTC) remedies for digestive disorders. And these can and do create additional digestive problems.
If an individual’s digestion is not working properly, the first thing is to understand what is sending the gut out-of-balance in the first place.
A low-fiber, high-sugar, processed, nutrient-poor, high-calorie diet causes all the wrong bacteria and yeast to grow in the gut and damages the delicate ecosystem in your intestines.
Overuse of medications that damage the gut or block normal digestive function, i.e., acid blockers (Prilosec, Nexium, etc.), anti-inflammatory medication (aspirin, Advil, and Aleve), antibiotics, steroids, and hormones.
Undetected gluten intolerance, celiac disease, or low-grade food allergies to foods such as dairy, eggs, or corn.
Chronic low-grade infections or gut imbalances with overgrowth of bacteria in the small intestine, yeast overgrowth, parasites.
Toxins like mercury and mold toxins damage the gut.
Lack of adequate digestive enzyme function from acid-blocking medications or zinc deficiency.
Stress can alter the gut’s nervous system, cause a leaky gut, and change the normal bacteria.
Visits for intestinal disorders are among the most common trips to primary care doctors. Unfortunately, most, which also includes most doctors, do not recognize or know that digestive problems wreak havoc in the entire body. This leads to allergies, arthritis, autoimmune disease, rashes, acne, chronic fatigue, mood disorders, autism, dementia, cancer, and more. Having proper gut and intestinal health is absolutely central to your health. It is connected to everything that happens in the body.
Should individuals with existing gastrointestinal problems eat bananas?
Bananas
Bananas can be easy to digest and are often recommended for nausea and diarrhea, however, not everyone can tolerate them. (MedlinePlus. 2021)
Bananas are high in fructose, sorbitol, and soluble fiber, which makes them a common trigger for gastrointestinal problems.
Additionally, individuals not used to eating a high-fiber diet may find it helpful to gradually increase fiber and drink more water to alleviate unpleasant symptoms.
If there is a suspicion of intolerance, IBS, or malabsorption, it is recommended to speak with a healthcare provider for an evaluation.
Bananas can make the stomach hurt due to:
Irritable bowel syndrome (IBS)
Cramping
Gas
Bloating
Other gastrointestinal (GI) problems.
Individuals can experience stomach discomfort if there is a fructose intolerance or a rare banana allergy.
Stomach Pain
Bananas are used to replenish potassium and other essential nutrients lost from vomiting or diarrhea.
Some individuals can experience bloating and gas after eating them.
One reason is because of their soluble fiber content.
Soluble fiber dissolves in water and is more readily fermented in the colon than insoluble fiber.
Bananas also contain sorbitol – a naturally occurring sugar that acts as a laxative and can cause gas, bloating, and diarrhea when consumed in large amounts. (U.S. Food and Drug Administration. 2023)
Irritable Bowel Syndrome – IBS
Bananas can be a common trigger food for individuals with IBS.
Bananas are also high in fructose/simple sugar especially when they have overripened.
Individuals who have IBS are advised to avoid bananas because they can trigger many of the same side effects as undigested lactose/sugar in milk. (Johns Hopkins Medicine. 2023)
Ripe bananas are considered to be high in FODMAPS – fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.
Individuals following a low FODMAP diet to manage IBS may want to avoid or limit consumption.
Fructose malabsorption is when the body cannot digest or absorb fructose correctly. This causes bloating gas and abdominal discomfort.
Hereditary fructose intolerance is very rare. It happens when the liver cannot assist in the breakdown of fructose.
This condition often causes more severe symptoms and requires additional treatment besides removing fructose from an individual’s diet. (UW School of Medicine and Public Health. 2019)
Most can tolerate small amounts of fructose found in fruits like bananas.
If you’re eating bananas that are too green or unripe, you may also experience stomach discomfort.
Unripened bananas contain high amounts of resistant starch. In large quantities, this can cause mild symptoms like gas and bloating. (Jennifer M Erickson, et al., 2018)

The Johns Hopkins Guide to Diabetes. What is resistant starch?
The digestive system breaks down the foods eaten so the body can absorb the nutrients. During digestion, the unnecessary parts of these foods are turned into waste/stool, which is evacuated during a bowel movement. When the digestive system stops functioning properly due to factors such as diet change, eating unhealthy foods, lack of physical activity/exercise, medications, and certain health conditions, can cause constipation. Constipation occurs when the body cannot have a regular bowel movement. The distention, gas, bloating and not being able to have a bowel movement cause irritability and stress, which can worsen constipation. Incorporating recommended nutrition can help restore regular bowel movements and gut function.
Recommended Nutrition For Constipation
Symptoms like abdominal pain, bloating, and difficult bowel movements are common. Diet and proper hydration have a significant role in digestive health, especially in relieving and preventing constipation. High-fiber foods, prebiotics, and adequate hydration from foods and beverages are essential for healthy bowel movements.
Fiber is found in whole grains, starches, fruits, and vegetables.
Soluble and insoluble fiber are important for digestive health.
Focusing on incorporating high-fiber fruits, vegetables, and whole grains.
Foods rich in prebiotics like fermented foods are recommended when constipated.
The recommended nutrition for constipation, according to a dietitian includes.
Avocados
Avocados can be paired with just about anything and are full of nutrients and fiber.
One avocado contains around 13.5 grams of fiber.
One avocado will provide almost half daily fiber needs.
Other high-fiber fruits: pomegranates, guava, raspberries, blackberries, and passionfruit.
Figs
Figs can be eaten fresh and dried.
Figs are considered a laxative and have been shown to treat and reduce constipation.
They contain antioxidants, polyphenols, polyunsaturated fatty acids, and vitamins.
Other fruits similar to a fig: dried apricots, prunes, and plums.
Plums
Plums, prunes dried plums are packed with fiber and prebiotics that have a natural laxative effect.
The added H2O makes the stools softer and easier to pass.
Natural fruit juices, like pear, apple, or prune are often prescribed for constipation.
Other fruits that aid in bowel movements: peaches, pears, and apples.
Kefir
Fermented foods like kefir are rich in beneficial bacteria that work to maintain digestive system health.
It can be consumed on its own or used in smoothies, cooking, and baking recipes.
Other fermented foods: kombucha, yogurt, sauerkraut, kimchi, miso, and tempeh.
Oat Bran
Oat bran is oatmeal that has not had the bran removed.
The bran contains beneficial nutrients including fiber, antioxidants, vitamins, and minerals.
Oat bran contains soluble and insoluble fiber, as well as beta-glucan/non-starchy polysaccharides.
All improve the composition of gut bacteria and promote healthy bowel movements.
Other beneficial grains: oatmeal, wheat bran, rye, and barley.
Incorporating Gut-Beneficial Foods
How to incorporate recommended nutrition gut-beneficial foods into a regular menu:
Smoothie
Use kefir or yogurt as a base then balance it out with fiber-rich fruits like mango, blueberries, and kiwi.
Snacks
Diversify snacks with a plate of fiber and prebiotics.
Nuts, cheese, crackers, fruit, and a yogurt or avocado dip.
Oatmeal
Try oat bran to increase fiber.
Sprinkle a serving of flaxseeds, chia seeds, or hemp seeds for added fiber and healthy fats.
Parfait
Yogurt parfaits can maximize nutrients, flavor, and textures in a bowl.
Layer up on a favorite yogurt with granola, nuts, fruit, and seeds.
Grain Bowl
Fiber found in whole grains and seeds like barley, farro, and quinoa, helps promote healthy digestion.
Make a bowl with a grain base, then top with a protein, fresh or grilled veggies, avocado, and dressing.
Talk with a registered nutritionist or other healthcare provider to discuss recommended nutrition plan options.

Pesto is a sauce that is made with garlic, pine nuts, basil, cheese, and olive oil, which creates a strong, rich flavor. It is used as a marinade, dip, salad dressing, sandwich spread, and a topping for dishes like pasta and pizza. It can be homemade or bought premade, including vegan varieties. It is made with nutritious ingredients and can be consumed as part of a balanced diet. The sauces can vary in nutrition, but in general, it is a rich source of healthy fats and is also part of the Mediterranean Diet.
Pesto
Carbohydrates
The sauce is not a significant source of complex carbohydrates, dietary fiber, or sugar.
A spoonful contains under 1 gram of carbohydrates.
It is often paired with foods rich in carbohydrates, like sandwiches, pizza, and pasta.
Fats
Nearly 60% of the calories in pesto come from fats, provided by the olive oil, cheese, and pine nuts.
There are 9.47 grams of fats per spoonful, which includes:
5.63 grams of monounsaturated fatty acids.
1.53 grams of saturated fatty acids.
1.68 grams of polyunsaturated fatty acids.
It also contains 2.56mg of cholesterol.
According to U.S. Dietary Guidelines for Americans, 20% to 35% of daily calories should come from fat.
Protein
The sauce is not a protein-rich food with only 1.38 grams of protein per tablespoon.
It is often used as a condiment, it can add flavor to other foods higher in protein.
Vitamins and Minerals
Pesto contains:
33.1mg of calcium.
36.8mg of phosphorus.
31.8mg of potassium.
9.76mg of magnesium.
Health Benefits
Some of the potential health benefits of pesto.
Antioxidant Properties
Garlic, pine nuts, olive oil, and basil are rich sources of antioxidants.
Antioxidants have an essential role in defending the body against free radical damage, which can lead to disease.
Diets high in antioxidants reduce the risk of various diseases, like heart disease and cancer.
Consuming antioxidant-rich foods like pesto on a regular basis can increase antioxidant levels.
Cardiovascular Benefits
Olive oil health benefits include the reduced risk of heart disease.
Substituting other high-fat foods like margarine, butter, and mayonnaise with olive oil can help lower the risk of heart disease and stroke.
Help Lower Cholesterol
Four different types of fats – saturated, trans, monounsaturated, and polyunsaturated fats.
Saturated fats can raise LDL/unhealthy cholesterol levels.
Foods rich in monounsaturated and polyunsaturated fats like pesto can help lower LDL cholesterol levels in the blood and support HDL/healthy cholesterol levels.
Weight Management
Pesto is commonly consumed on the Mediterranean diet and can be part of a nutritious lifestyle that supports a healthy weight.
Research has shown that following a Mediterranean diet can lead to and maintain long-term changes in weight management.
Store-bought pesto can contain a large amount of sodium.
Individuals following a low-sodium diet or taking heart medications should check with their doctor before consuming these products.
To control the amount of sodium, consider making a homemade recipe that uses less salt and aligns with individual dietary preferences.
Basil is the main ingredient but some varieties are made with other herbs.
Pesto traditionally contains parmesan cheese/milk products and pine nuts/tree nuts which are common food allergens.
The sauce is a vegetarian-friendly sauce, but vegans can look for cheese and dairy-free versions.
It is possible that an allergic reaction can occur in individuals allergic to dairy products and nuts.
Individuals allergic to nuts can choose nut-free varieties.

Before the body can benefit from consumed nutrients, the gastrointestinal tract has to digest and absorb the foods. Before eating, the body needs to feel hungry. However, hunger is not the same as appetite. Hunger is a physical reaction caused by hormonal and chemical changes in the body when fuel is needed. Appetite is more of a desire to eat and can be a learned response. It is one reason why individuals can eat when they are not hungry. The body comprises different hormones that regulate hunger, digestion, and appetite.
Hunger Digestion Regulating Hormones
Hunger Hormones
Hunger is the feeling when the body needs food. When the body has enough, hunger should subside. That’s because various hormones regulate hunger.
Leptin
Leptin is a hormone secreted by adipose tissue/fat into the bloodstream.
The more fat in the body, the higher the blood levels of leptin.
Leptin level also increases with food intake and is higher in females than males, but overall, it lowers with age.
Increased leptin levels trigger the hypothalamus to reduce hunger.
Ghrelin
Ghrelin is a hormone produced by the stomach and small intestine when the stomach is empty.
Like leptin, it also works with the hypothalamus.
However, instead of suppressing hunger, it increases hunger.
Insulin
The pancreas produces this hormone.
It is mostly known for regulating blood sugar levels.
It also suppresses hunger.
Adiponectin
Adiponectin is a hormone secreted by fat cells.
As body fat levels go down, this hormone goes up.
If fat levels go up, adiponectin levels go down.
Cholecystokinin
Cholecystokinin is a hormone produced in the small intestine during and after a meal.
It triggers the release of bile and digestive enzymes into the small intestine.
These suppress hunger and make the body feel full.
Peptide YY
This hormone suppresses appetite for about 12 hours after eating.
Made by both the large and small intestines after eating.
Glucocorticoids
Adrenal glands make these hormones, and their primary function is to regulate inflammation and other processes, but they also impact hunger.
A cortisol deficiency reduces appetite, but excessive amounts of glucocorticoids increase hunger.
Digestion Hormones
Digestion is coordinated and regulated by hormones.
Gastrin
Gastrin is a hormone the stomach and the small intestine release when eating.
Gastrin stimulates the release of hydrochloric acid and pepsinogen in the stomach to speed up digestion.
Gastrin stimulates glucagon, which works with insulin to regulate blood sugar.
Secretin
Secretin is a hormone made by the small intestine.
It is secreted into the bloodstream when the acidic chyme from the stomach enters the small intestine.
Secretin stimulates the pancreas to release bicarbonate digestive liquids into the small intestine.
The bicarbonate neutralizes the acidity.
Secretin acts on the stomach to trigger the production of pepsinogen to help break down proteins.
Cholecystokinin – CCK
The small intestine makes and releases CCK into the bloodstream.
Essential fat digestion stimulates the gallbladder to release bile into the small intestine.
It also triggers the pancreas to release various digestive enzymes so they can break down fats, carbohydrates, and proteins.
It stimulates the pancreas to release insulin and slows down stomach digestive activity.
Peptide YY and Enterogastrone
Released by the small intestine, two more hormones slow digestion down and decrease the production of digestive secretions.

Regular exercise and physical activity help with cardiovascular health, improved mood, better management of chronic conditions, and can help digestion. For individuals with any GI distress or inflammatory bowel disease that has caused digestive enzyme deficiencies, exercise, and physical movement have been found to provide digestive aid. Here we look at activities to help digestion.
Exercises To Help Digestion
When exercising the body, the cardiac output/volume of blood the heart pumps every minute increases as the demand for oxygenated blood throughout the body increases, particularly in the working muscles. During exercise, the same increase in blood circulation happens within the digestive system’s muscle groups. The blood flow to digestive organs causes peristalsis, which is involuntary constriction and relaxation of the muscles in the digestive tract. This process helps move food efficiently through the gastrointestinal tract. Exercise supports the growth of beneficial gut bacteria to maintain a healthy digestive system.
Exercise helps relieves stress which means lower amounts of cortisol.
Research has found that elevated cortisol levels are associated with compromised digestive function.
Tai chi has been shown to improve immune function and inflammation of the gut and is a helpful tool for maintaining homeostasis/gut balance.
This is a form of moderate-intensity exercise and meditative practice.
The emphasis is on slow controlled movements and deep breathing.
This makes it recommended for individuals looking to improve digestion and those with gastrointestinal conditions.
Pilates
Pilates is the practice that targets abdominal muscles and utilizes diaphragmatic breathing to help individuals perform a series of movements to strengthen and elongate the body’s muscles.
Individuals who perform this exercise often report relief from bloating and gas.
Whether new to exercise or returning, a plan can help you get there. Meeting with a fitness trainer or sports chiropractor is a great place to begin if you have limited knowledge about what works best for your body and schedule.
A certified trainer can help guide you toward an achievable program that focuses on gut health.
Individuals with a GI disorder should talk with their doctors before starting a new exercise plan.
This does not mean you can’t do intense exercises like running; you’ll want to work with a doctor to set up a program that doesn’t cause flare-ups.
Aim for roughly three hours of moderate-intensity weekly exercise to support a healthy digestive system.
Sit less and move more.
Do at least two or more muscle-strengthening activities of moderate intensity every week.

The human body is about 60% to 75% water. Adequate hydration is necessary to flush toxins from the body, is essential for cognition, prevents dehydration, and provides energy. It can reduce headache onset and aid in weight management. With the summer heat kicking in, it is imperative to replenish the body’s systems from lost sources with water, other rehydrating beverages, and fruits and vegetables. It can be difficult for individuals to drink enough water, making it feel like a chore. Drinking lime water by adding a slice of lime or lime juice can add flavor with beneficial properties for everyday health, nutritional properties, and only a trace amount of sugar.
Lime Water
Citrus fruits offer anti-oxidative and anti-inflammatory effects and can help protect the cardiovascular system. Limes can provide a sour boost and a refreshing twist to a cold glass of water.
Lime Nutrition
Limes provide an excellent source of antioxidants that protect the body by preventing or stopping cell damage caused by free radicals or chemicals. Limes contain:
Calcium
Potassium
Magnesium
Vitamins A, B, C, and D
Digestion and Gut Health
Drinking lime water improves digestion.
The acidic nature of limes causes salivation, which is good for breaking down food for better digestion.
Flavonoids in limes stimulate the secretion of digestive juices to regulate different gut physiology in the gastrointestinal tract. They also stimulate the secretion of:
Gut hormones
Digestive juices
Gut microbiota
These play an important role in immune function to fight the growth of certain harmful bacteria that can lead to infection.
The acidity of limes can clear the excretory system and stimulate bowel activity for individuals experiencing constipation.
For individuals with frequent heartburn or acid reflux, drinking a glass of warm water with two teaspoons of lime juice 30 minutes before meals can help prevent reflux symptoms.
Fight Infections
The body’s risk of infection is higher during cold and flu season.
Vitamin C and antioxidants can strengthen the immune system to help the body fight off infections like the cold and flu virus.
Individuals who take vitamin C regularly may see milder symptoms and shorten the duration of a cold.
Improve Cardiovascular Health
Limes are a good source of magnesium and potassium for heart health.
Potassium can naturally lower blood pressure and improve blood circulation, which reduces the risk of a heart attack and stroke.
Research is ongoing on lime compounds called limonins that could help reduce cholesterol levels.
Lower Blood Sugar
Limes can be helpful for individuals with diabetes.
Limes have a low glycemic index.
They help regulate how the body absorbs sugar into the blood.
As a result, individuals may experience fewer spikes.
Reduce Inflammation
Arthritis, gout, and other joint problems are caused by inflammation.
Vitamin C can reduce inflammation to help relieve symptoms of arthritis and similar conditions that cause joint pain and stiffness.
To start the day and increase metabolism, drink a glass of lime water in the morning or have the juice of a lime wedge before meals.

Not getting enough fiber in one’s diet can lead to fiber deficiency. Fiber helps support gut and microbiome health. Individuals not getting enough fiber may experience irregular bowel movements, constipation, blood sugar fluctuations, not feeling full/satisfied after eating, or rising cholesterol levels. About 100 trillion microorganisms in the gut are integral to maintaining a healthy immune system. Fiber is the food these microorganisms eat that helps them to do their job. Without the proper amount, the immune system’s health may also be compromised.
Fiber and Gut Health
Fiber and gut health benefits include regulating the body’s sugars, helping to keep hunger and blood sugar in check, helping to maintain a healthy weight, its ability to prevent or relieve constipation, reduce the risk of diabetes, heart disease, and certain types of cancer.
Dietary fiber, or roughage, is the part of plant foods the body can’t digest or absorb.
It passes through the stomach, small intestine, and colon and out of the body.
It is found mainly in fruits, vegetables, whole grains, and legumes.
Soluble and insoluble forms are important to overall health.
Types
Soluble Fiber
This type dissolves in water to form a gel-like substance.
It can help lower blood cholesterol and glucose levels.
It is found in oats, peas, beans, apples, citrus fruits, carrots, and barley.
Insoluble Fiber
This type of fiber promotes the movement of material through the digestive system.
It increases stool bulk, benefiting individuals who struggle with constipation or irregular stools.
Whole-wheat flour, wheat bran, nuts, beans, and vegetables, such as cauliflower, green beans, and potatoes, are good sources.
Benefits
Healthy Bowel Movements
Dietary fiber increases stool weight and thickness and makes it soft.
Fiber helps to solidify the stool by absorbing water and adding bulk.
A thicker stool is easier to pass, decreasing the potential for constipation and other problems.
Maintains Bowel Health
A high-fiber diet can lower the risk of developing hemorrhoids and small pouches in the colon/diverticular disease.
Studies have also found that a high-fiber diet can help lower the risk of colorectal cancer.
Some fiber gets fermented in the colon.
Researchers are looking at how this can help prevent diseases of the colon.
Lowers Cholesterol
Soluble fiber found in beans, oats, flaxseed, and oat bran can help lower blood cholesterol levels by lowering low-density lipoprotein or unhealthy cholesterol levels.
Studies also have shown that high-fiber foods can help reduce blood pressure and inflammation.
Regulates Blood Sugar Levels
In individuals with diabetes, fiber, particularly soluble fiber, can slow the absorption of sugar and improve blood sugar levels.
A healthy nutrition plan that includes insoluble fiber can help reduce the risk of developing type 2 diabetes.
Helps Achieve Healthy Weight
High-fiber foods can be more filling than low-fiber foods, helping individuals eat less and stay satisfied.
High-fiber foods can also take longer to eat and are less energy dense, meaning they have fewer calories.
Getting More Fiber
Ideas for adding more fiber to meals and snacks:
Fiber to Start The Day
Choose a high-fiber breakfast cereal with five or more grams of fiber per serving.
Choose cereals with whole grain, bran, or fiber in the name.
Add a few tablespoons of unprocessed wheat bran to the cereal.
Add Whole Grains
Try to make at least half of the grains eaten whole grains.
Look for bread that lists whole wheat, whole-wheat flour, or another whole grain as the first ingredient, with at least 2 grams of dietary fiber per serving.
Experiment with whole-wheat pasta, brown rice, wild rice, barley, and bulgur wheat.
Baked Foods
Substitute whole-grain flour for half or all white flour when baking.
Add crushed bran cereal, unprocessed wheat bran, or uncooked oatmeal to muffins, cakes, and cookies.
Legumes
Beans, peas, and lentils are recommended sources.
Add kidney beans to soups or salads.
Make nachos with refried black beans, fresh vegetables, whole-wheat tortilla chips, and healthy salsa.
Fruit and Vegetables
Fruits and vegetables are rich in fiber and vitamins and minerals.
Try to eat a favorite fruit daily.
Healthy Snacks
Fresh fruits, raw vegetables, low-fat popcorn, and whole-grain crackers are healthy choices.
Try for a handful of nuts or dried fruits; however, be aware that nuts and dried fruits can be high in calories.
Moderation
High-fiber foods are beneficial for the body’s health.
Adding too much fiber can promote intestinal gas, abdominal bloating, and cramping.
Increase fiber gradually over a few weeks.
This allows the natural bacteria in the digestive system to make adjustments.
Maintain hydration, as fiber works best when it absorbs water.
Individuals not sure how to incorporate more fiber can consult a nutritionist and health coach to help begin the process.
