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.
For individuals with digestive and other health issues, could resistant starch provide health benefits?
Resistant Starch
Typical starchy foods are simple starches that are rapidly digested. This sends their sugars into the bloodstream, contributing to weight gain and increasing the risk of diabetes and heart disease. (Erik E. J. G. Aller, et al., 2011) Resistant starch is a food component that is a type resistant to digestion. This means that it passes into the large intestine and interacts with the gut flora. Foods that contain resistant starch pass through the stomach and small intestine without being absorbed. In the large intestine, they are fermented by the gut bacteria which releases substances that are beneficial to health.
Health Benefits
Studies on the health benefits are ongoing. Scientists are researching how it can help with weight management and colon health:
Weight Management
Research is beginning to show indications that foods with resistant starch can help with weight loss and the ability to help offset the diseases associated with weight gain that include: (Janine A. Higgins. 2014)
High cholesterol
Diabetes
Metabolic syndrome
Cardiovascular disease
Colon Health
In addition, researchers are finding preliminary evidence indicating that resistant starch might possibly help with: (Diane F. Birt, et al., 2013)
A prebiotic that encourages a healthy balance of gut flora.
Inflammatory bowel disease symptom improvement.
Prevention of colon cancer.
Protection against diverticulitis.
However, more research is needed.
Consumption Amount
Estimates on how much should be consumed range from a minimum of 6 grams to a maximum of 30 grams. It is estimated that most individuals consume less than 5 grams per day, (Mary M. Murphy, et al., 2008). As individuals increase their intake, it is recommended to do so slowly, to minimize unwanted gas and bloating.
Bananas
Bananas are a healthy source of resistant starch.
They have the maximum amount when they are unripe.
The resistant starch content reduces as the banana ripens.
If green/unripe bananas are not appealing, making a smoothie can help with the taste.
Potatoes
Potatoes have their highest level of resistant starch when raw.
However, individuals can maximize their intake by allowing the potatoes to cool before eating.
Rice
Levels of resistant starch depend on whether the rice is white or brown.
Similar to potatoes, intake can be maximized from rice by allowing the rice to cool.
Oats
Cooking oats in water, as most are accustomed to making oatmeal, diminishes the resistant starch content.
Rolled or steel-cut oats are recommended as dependable sources of resistant starch.
Chickpeas
Chickpeas, also known as garbanzo beans, are nutritional powerhouses.
They are a healthy source of dietary fiber, along with many vitamins and minerals, and resistant starch.
Cooked and/or canned chickpeas contain high levels of resistant starch.
They go with salads or as a side dish or snack.
For individuals with IBS, well-rinsed canned chickpeas are considered to be low in FODMAPs or carbohydrates that can contribute to symptoms. (Anamaria Cozma-Petruţ, et al., 2017)
It is recommended to keep the serving size to a 1/4 cup.
Lentils
Lentils serve as a healthy source of plant-based protein.
Cooked they can provide resistant starch.
They can be prepared in soups or side dishes.
From a can, they can be IBS-friendly by being well-rinsed and limited to a 1/2 cup serving.
Bread
Various breads offer varying levels of resistant starch.
Pumpernickel bread contains high levels.
Breadsticks and pizza crusts have high levels.
Individuals with IBS may be reactive to the FODMAP fructan or the gluten protein.
Other recommended high-resistant starch options are corn tortillas or artisanal sourdough bread that is traditionally prepared.
Green Peas
Green peas, even when cooked, are a healthy source of resistant starch.
They can be prepared in soups or as a side dish.
However, green peas have been found to be high in the FODMAP GOS and could be problematic for individuals with IBS. (Anamaria Cozma-Petruţ, et al., 2017)
Beans
Most types of cooked and/or canned beans are recommended sources of resistant starch.
The highest levels are found in white and kidney beans.
They can be served in soups, as a side dish, or mixed with rice.
Beans are a high-FODMAP food and could contribute to digestive symptoms in individuals with IBS.

Individuals need to eat more fiber for optimal gut health. Can adding avocado to their diet help improve the gut microbe diversity?
Avocado Gut Support
A diverse gut microbiome is beneficial to overall health. According to a recent study, eating one avocado a day can help maintain the gut microbes healthy, diverse, and balanced. (Sharon V. Thompson, et al., 2021) The researchers observed positive changes in gut bacteria and increased bacterial diversity in individuals who consumed an avocado every day for 12 weeks. (Susanne M Henning, et al., 2019)
Gut Diversity
The gut microbiome refers to the microorganisms living in the intestines. There are around 100 trillion microorganisms, including bacteria, viruses, fungi, and more, exist in the gastrointestinal tract. (Ana M. Valdes, et al., 2018) Having a diverse microbiome means that the body has a range of different organisms that offer various health benefits. Not having enough bacterial diversity has been linked to: (Ana M. Valdes, et al., 2018)
Arthritis
Obesity
Type 1 diabetes
Type 2 diabetes
Inflammatory bowel disease
Celiac disease
Arterial stiffness
Atopic eczema
Why Avocados?
The Institute of Medicine recommends a daily fiber intake ranging from 19 grams to 38 grams per day, depending on various factors like age. (Diane Quagliani, Patricia Felt-Gunderson. 2016)
Including foods like avocados in a healthy diet can help meet daily fiber requirements.
Fruit fiber like pectin, has been shown to promote a healthy gut microbiome as well. (Beukema M, et al., 2020)
Researchers suggest this could be because of pectin’s positive effect on beneficial probiotics.(Nadja Larsen, et al., 2018)
Although further research is needed fiber is believed to help protect the lining of the colon by increasing the bulk and weight of stool and expediting elimination.
Fiber also adds bulk to an individual’s diet and slows the speed of digestion, which makes the body feel fuller longer.
Improved Gut
Individuals can support a healthy microbiota by making small adjustments in their diet, including:
Eating a variety of fruits and vegetables with the skin, as this is where a majority of the nutrition is.
Fermented foods like yogurt, kombucha, sauerkraut, kimchi, and kefir.
Limiting consumption of processed foods, sugar, and artificial sweeteners.
If there are more avocados that can be eaten before they overripen, they can be frozen.
Peel and slice them first, then place them in freezer bags to have year-round.
They are rich in healthy fat, however, in moderation, they are not likely to contribute to weight gain.
Individuals can work toward having a diverse gut microbiome by paying attention to the foods they eat. Specific foods and dietary patterns can influence the different types of bacterial diversity which can support health.

For individuals with stomach issues, can maintaining gut flora balance promote and improve gut health?
Gut Flora Balance
Maintaining gut flora balance is part of optimal digestive health. Gut microbiota, gut microbiome, or gut flora, are the microorganisms, including bacteria, archaea, fungi, and viruses that live in the digestive tract. The type and amount of bacteria present depend on their location in the body which could be the small intestine and colon. This is the storage housing for waste/stool, and the colon comprises hundreds of different types of bacteria, which have specific jobs and functions.
Unhealthy Flora
The more common pathogens are bacteria that can cause illness if left unchecked, including germs like streptococcus/strep throat or E. coli/urinary tract infections and diarrhea. Other common germs found in the colon include: (Elizabeth Thursby, Nathalie Juge. 2017)
Clostridioides Difficile
C. diff overgrowth can cause watery foul-smelling stools daily, and abdominal pain and tenderness.
Enterococcus Faecalis
Enterococcus faecalis is a cause of post-surgical abdominal and urinary tract infections.
Escherichia Coli
E. coli is the most common cause of diarrhea in adults.
This bacteria is present in almost every healthy adult’s colon.
Klebsiella
Klebsiella overgrowth is associated with a Western diet that consists of various meat and animal products.
Bacteroides
Bacteroide overgrowth is associated with colitis, which causes painful inflammation of the colon.
Healthy Flora
Healthy bacteria like Bifidobacteria and Lactobacillus, help maintain gut flora balance and keep the unhealthy bacteria in check. Without healthy flora, the entire colon can become overrun by bad flora, which can result in symptoms like diarrhea and/or illness. (Yu-Jie Zhang, et al., 2015) These protective, microscopic germs have important functions that include:
Assisting with vitamin synthesis – vitamins B and K in the small intestine.
Increases immune system function.
Maintaining regular bowel movements.
Maintaining a clean colon naturally without the need for colon cleansers.
Destroying the unhealthy bacteria.
Preventing unhealthy bacteria overgrowth.
Breaking up gas bubbles from food fermentation.
Bacterial Dismantling
Whether labeled as healthy bacteria or unhealthy, they are both single-celled organisms that can be destroyed quite easily. Sometimes, it is necessary, like when having to take antibiotics to kill a strep throat infection. However, the antibiotics also kill the beneficial bacteria, which can lead to compounding problems that can include: (Mi Young Yoon, Sang Sun Yoon. 2018)
Bowel irregularity – diarrhea and constipation.
Yeast overgrowth – can cause itching, burning around the anus and lead to vaginal and oral yeast infections.
Dysbiosis – the technical name for a lack of healthy bacteria or a bacterial imbalance.
Complications for individuals suffering from irritable bowel syndrome.
There are different ways to destroy bacteria including.
Prolonged diarrhea – can flush out the bad and good bacteria.
Stress
Completing a bowel prep, like those required for a colonoscopy.
Diagnosing Gut Flora Issues
Many times, problems with gut flora will correct themselves, and no action is required. However, individuals facing chronic bowel problems, like colitis or inflammatory bowel disease, may require medical intervention of their colon’s bacteria.
Comprehensive Digestive Stool Analysis/CDSA is a stool test that checks what type and amount of bacteria are present, nutrient absorption rates/digestion speed, and how well food is digested.
If there is a significant difference in the proportion of unhealthy versus beneficial bacteria, a healthcare provider may suggest taking a probiotic or a live microbial supplement to help repopulate and maintain gut flora balance.

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.
