Digestive health benefits explained -
While research into fermented foods is limited, the bacteria found in some fermented foods have been linked with digestive health and other benefits.
Breastfeeding helps an infant develop a healthy gut microbiome, which may help protect against certain health conditions later in life. Regular cardiovascular exercise such as walking and cycling can stimulate the muscles of the gut to move digestive contents through the body. Stress can impact your gut health.
Manage your stress levels by exercising regularly, getting enough sleep, socialising, using relaxation techniques and eating well. Not getting enough or sufficient quality of sleep may impact your gut microbiome and may contribute to digestive discomfort.
It is best to improve your gut health through food and other lifestyle factors rather than supplements. There are many nutrients in wholefoods that cannot be packaged into a single supplement. Nutrients in foods also interact with each other in a helpful way and this cannot be replicated in a pill.
Many people are interested in taking probiotic supplements. In some cases, there is research to support taking a probiotic, however just like medications, you need to take a specific probiotic for the health condition you are trying to manage.
While antibiotics can be very important and useful, they can also have a negative impact on your gut microbiome. Antibiotics aim to kill the harmful bacteria when you have an infection or illness, but in doing so they can remove some of the beneficial bacteria in your gut.

Gut Health is a popular term used by consumers, the food industry, and practitioners, but what does it mean? Five major criteria have been identified to define gut health from a healthcare perspective 1 :. Gut discomfort includes a variety of symptoms that may negatively impact the status of well-being.
Some of these symptoms are bloating, flatulence, abdominal pain, diarrhea, constipation, and borborygmi rumbling. Common disorders associated with these symptoms include lactose intolerance and irritable bowel syndrome IBS. Often dietary changes can help alleviate or help manage these disorders.
Food intolerances are not life-threatening, but intolerance to one or more foods can be life-altering; gut discomfort can often be so painful or debilitating that individuals can find it hard to focus on day-to-day activities. In addition, having to restrict food based on intolerance can be a daily frustration.
Gut microbiome refers to the microorganisms microbiota living in our intestines. Gut microbiota also play a role in gut health and management of several GI disorders. The composition of the gut microbiome is affected by dietary intake and can be changed by dietary carbohydrate, prebiotics, and probiotics.
Within our gut microbiome, there are types of bacteria that are helpful for our health. These bacteria have several beneficial functions:.
However, there are also bacteria which can live in our gut that can be harmful. Most recently, a gut microbiome-brain connection has been identified, meaning the different populations of bacteria in our gut can even impact how our brains work 2.
Foods that help create and nourish a healthy gut microbiome include prebiotics fibers that bacteria use for energy, e. garlic, onions, bananas, inulin , fermentable fibers e.
beans, legumes, fruits, and vegetables , and fermented foods or probiotics foods containing bacteria that survive the digestive process and take residence in our gut, e.
yogurt, kefir, kimchi. Lactose intolerance is the inability to digest lactose, a natural sugar in dairy, and it occurs when a person has either a limited amount of lactase enzyme that breaks down lactose available or their lactase enzyme is not as effective as it should be.
There, the bacteria of our microbiome can use the lactose for fuel, creating byproducts like gas. Lactose intolerant individuals may experience gas, bloating, nausea, abdominal cramps, or diarrhea when they consume significant amounts of lactose.
The current recommendation to deal with lactose intolerance is to reduce lactose intake, not exclude it entirely. Most people can tolerate at least 12 g lactose the amount of an 8 oz glass of milk without any symptoms or 18 g of lactose spread throughout the day Click here to view the lactose content of common foods.
Evidence suggests that probiotics may help reduce or eliminate the symptoms of lactose intolerance, specifically lactic acid bacteria that is found in yogurt, fermented milk and probiotic supplements Irritable bowel syndrome IBS is a functional bowel disorder, which means there are no structural abnormalities in the gut or laboratory tests to diagnose the disease.
The common complaints are abdominal pain, bloating, and altered bowel habits diarrhea and constipation. Enter FODMAP. What is FODMAP? FODMAP is an acronym that stands for fermentable F , oligosaccharides O , disaccharides D , monosaccharides M , and A , polyhydric alcohols P 7.
The oligosaccharides include fructoligosaccharides FOS , galactooligosaccharides GOS , fructans, raffinose, and inulin. The disaccharides include lactose and sucrose; monosaccharides refer to fructose. The polyhydric alcohols include sorbitol, mannitol, xylitol, and maltitol.
Although they sound complicated, the main message is that these carbohydrates can be fermented by bacteria in our gut, which produces by-products like gas and can create discomfort.
The FODMAP diet is relatively new, with most of the literature on its efficacy occurring over the past five years. Although earlier studies brought some skepticism, current publications shed a better light on FODMAP benefits. Most of the data indicate that it reduces functional symptoms of IBS based on findings from dietitians who use the diet with patients and clients The FODMAP diet involves two phases: elimination and reintroduction.
The elimination diet, avoidance of high FODMAP foods, should be followed for weeks. Once the person is symptom free, high FODMAP foods are added back into the diet, and tolerance is assessed.
Examples of high FODMAP foods can be found in the table below. Additional information about the diet and a list of low FODMAP and high FODMAP foods can be found here.

Many organs make up the digestive system. Digestion begins the moment food is chewed and travels from the mouth, down the esophagus, and into the stomach. Once in the stomach, food is mixed with digestive enzymes and then slowly emptied into the small intestine, which further breaks down food, absorbs nutrients, and sends them into the bloodstream.

Another notable benefit, often overlooked by those outside the medical field, is that fiber acts as fuel for your gut microbiome, that large collection of bacteria, viruses, fungi, and other microbes that live in your gastrointestinal tract.
These microbes exist symbiotically with the digestive system and, research shows, support energy harvesting, digestion, and immune defense. Read on to find out about good sources of fiber and if you are getting enough to fuel your microbiome. A study published in Medicine in Microecology reported that dietary fiber intake is substantially lower today than it was in ancestral populations, especially in high-income countries.
This is due in part to industrialization and the rise of a westernized diet that features high levels of processed foods, refined sugars, animal proteins, and saturated fats. The recommended daily fiber intake for women ages 19 to 50 is 25 grams g , while men of the same age are encouraged to get 38 g of fiber per day.
Women and men over 50 require less fiber in their diets but should still aim for 21 g and 30 g per day respectively. American adults, on average, eat 10—15 g of fiber per day, according to Harvard Health.
Quigley highlights that the long-term repercussions of a low-fiber diet on gut health can be significant, particularly if the pattern is established during childhood. The good news is that fiber is relatively easy to incorporate into your daily life, especially when you view it in the context of food, rather than focusing solely on the nutrient itself.
A simple shift in perspective might be the catalyst you need to kick-start your journey toward a fiber-rich diet. Kelly Kennedy, RDN , the manager of nutrition at Everyday Health, works with her patients to identify gradual strategies for including more nutrient-rich foods.
It has to be very personal. There are two main types of dietary fiber, soluble and insoluble, both of which should be part of your diet every day. Plant foods contain both soluble and insoluble fiber, but some are higher in one than the other.
Soluble fiber dissolves in water, per Mayo Clinic , and helps to lower cholesterol, stabilize blood sugar, and slow the absorption of carbohydrates from food. It also softens stool. Good sources of soluble fiber include:. Insoluble fiber attracts water to the intestine , which adds bulk to stool and promotes the movement of waste products through your digestive system.
It can be extremely beneficial for people who struggle with constipation and irregularity. Good sources of insoluble fiber include:. Here are some tips from Harvard T.
Chan School of Public Health for incorporating more fiber into your diet. It is understood that there are links between gut health and: the immune system mental health autoimmune diseases endocrine disorders — such as type 2 diabetes gastrointestinal disorders — such as irritable bowel syndrome and inflammatory bowel disease cardiovascular disease cancer sleep digestion.

Inflammation can allow an abscess a pocket of pus to develop. With UC, inflammation in the lining of the large intestine the colon causes ulcers. This can cause bleeding, diarrhea, weight loss, and fatigue.
Other symptoms can vary depending on the severity of the inflammation and where it occurs in the large intestine. They include:. Irritable bowel syndrome IBS. IBS is characterized by recurrent bouts of constipation or diarrhea or both , abdominal pain, bloating, and gas.
The severity and duration of symptoms vary. Some are mild and come and go, while others are severe and last several weeks. Some people can go months or years between episodes. Most people are never cured of IBS, but dietary changes, medication, and stress management can help manage the condition.
Gallstones are hardened bits of bile that form inside the gallbladder, a pear-shaped pouch that sits just below the liver. Bile makes it easier for the body to digest fat. Small stones can pass out of the body through the intestines. However, gallstones can cause symptoms if they get caught in the narrow outlet of the gallbladder or in the ducts that drain the gallbladder.
Symptoms include abdominal pain, usually high in the abdomen and often in the center or on the right side where the gallbladder is located , and can spread to the area of the right shoulder blade.
When symptoms recur or the gallbladder becomes inflamed, the gallbladder needs to be surgically removed. Thanks for visiting. Don't miss your FREE gift. The Best Diets for Cognitive Fitness , is yours absolutely FREE when you sign up to receive Health Alerts from Harvard Medical School.
