10 Ways to Improve Your Gut Bacteria, Based on Science
Collectively, they are known as your gut microbiota, and they are hugely important for your health. However, certain types of bacteria in your intestines can also contribute to many diseases. Interestingly, the food that you eat greatly affects the types of bacteria that live inside you. Here are 10 science-based ways to improve your gut bacteria. There are hundreds of species of bacteria in your intestines.
Each species plays a different role in your health and requires different nutrients for growth. Generally speaking, a diverse microbiota is considered to be a healthy one. This is because the more species of bacteria you have, the greater number of health benefits they may be able to contribute to 1 , 2 , 3 , 4.
A diet consisting of different food types can lead to a diverse microbiota 5 , 6 , 7. Unfortunately, the Western diet is not very diverse and is rich in fat and sugar. A few studies have shown that gut microbiota diversity is much greater in people from rural regions of Africa and South America than those from Europe or the US 8 , 9. Fruits and vegetables are the best sources of nutrients for a healthy microbiota.
They are high in fiber , which can't be digested by your body. However, fiber can be digested by certain bacteria in your gut, which stimulates their growth. Some high-fiber foods that are good for your gut bacteria include :. One study found that following a diet high in fruits and vegetables prevented the growth of some disease-causing bacteria Apples, artichokes, blueberries, almonds and pistachios have all been shown to increase Bifidobacteria in humans 11 , 12 , 13 , Bifidobacteria are considered beneficial bacteria, as they can help prevent intestinal inflammation and enhance gut health Fermented foods are foods altered by microbes.
The process of fermenting usually involves bacteria or yeasts converting the sugars in food to organic acids or alcohol. Examples of fermented foods include:.
Many of these foods are rich in lactobacilli , a type of bacteria that can benefit your health. People who eat a lot of yogurt appear to have more lactobacilli in their intestines. These people also have fewer Enterobacteriaceae , a bacteria associated with inflammation and a number of chronic diseases Similarly, a number of studies have shown that yogurt consumption can beneficially modify intestinal bacteria and improve symptoms of lactose intolerance in both infants and adults 17 , 18 , Certain yogurt products may also reduce the abundance of certain disease-causing bacteria in people with irritable bowel syndrome.
Two studies showed that yogurt also enhanced the function and composition of the microbiota However, it is important to note that many yogurts, especially flavored yogurts, contain high levels of sugar.
Therefore, the best yogurt to consume is plain, natural yogurt. This kind of yogurt is made only of milk and bacteria mixtures, which are sometimes referred to as "starter cultures. Furthermore, fermented soybean milk may promote the growth of beneficial bacteria, such as Bifidobacteria and lactobacilli , while decreasing quantities of some other disease-causing bacteria.
Kimchi may also benefit the gut flora 21 , Artificial sweeteners are widely used as replacements for sugar. However, some studies have shown that they can negatively affect the gut microbiota.
One study in rats showed that aspartame , an artificial sweetener , reduced weight gain, but it also increased blood sugar and impaired insulin response The rats fed aspartame also had higher Clostridium and Enterobacteriaceae in their intestines, both of which are associated with disease when present in very high numbers.
Another study found similar results in mice and humans. It showed changes in the microbiota made artificial sweeteners have negative effects on blood sugar levels Prebiotics are foods that promote the growth of beneficial microbes in the gut.
They are mainly fiber or complex carbs that can't be digested by human cells. Instead, certain species of bacteria break them down and use them for fuel. Many fruits, vegetables and whole grains contain prebiotics, but they can also be found on their own. Resistant starch can also be prebiotic. This type of starch is not absorbed in the small intestine. Rather, it passes into the large intestine where it is broken down by the microbiota.
Many studies have shown that prebiotics can promote the growth of many healthy bacteria, including Bifidobacteria. Many of these studies were conducted in healthy people, but some studies have shown that prebiotics can be beneficial for those with certain diseases.
For example, certain prebiotics can reduce insulin, triglycerides and cholesterol levels in people who are obese 25 , 26 , 27 , 28 , 29 , 30 , These results suggest that prebiotics may reduce the risk factors for many diseases associated with obesity, including heart disease and diabetes. A baby's microbiota begins to properly develop at birth. However, some recent studies suggest that babies may be exposed to some bacteria before birth During the first two years of life, an infant's microbiota is continuously developing and rich in beneficial Bifidobacteria , which can digest the sugars in breast milk Many studies have shown that infants who are formula fed have an altered microbiota that has fewer Bifidobacteria than infants who are breastfed 33 , 34 , Breastfeeding is also associated with lower rates of allergies, obesity and other diseases that may be due to differences in the gut microbiota Whole grains contain lots of fiber and non-digestible carbs , such as beta-glucan.
These carbs are not absorbed in the small intestine and instead make their way to the large intestine. In the large intestine, they are broken down by the microbiota and promote the growth of certain beneficial bacteria.
Whole grains can promote the growth of Bifidobacteria , lactobacilli and Bacteroidetes in humans 37 , 38 , 39 , 40 , In these studies, whole grains also increased feelings of fullness and reduced inflammation and heart disease risk factors. Diets containing animal-based foods promote the growth of different types of intestinal bacteria than plant-based diets do 42 , A number of studies have shown that vegetarian diets may benefit the gut microbiota.
This may be due to their higher fiber contents. One small study found that a vegetarian diet led to reduced levels of disease-causing bacteria in obese people, as well as reduced weight, inflammation and cholesterol levels Another study found that a vegetarian diet significantly decreased disease-causing bacteria, such as E. However, it is unclear if the benefits of a vegetarian diet on the gut microbiota are simply due to a lack of meat intake.
Also, vegetarians tend to lead healthier lifestyles than omnivores. Polyphenols are plant compounds that have many health benefits, including reductions in blood pressure, inflammation, cholesterol levels and oxidative stress Polyphenols can't always be digested by human cells. Given that they aren't absorbed efficiently, most make their way to the colon, where they can be digested by gut bacteria 47 , Polyphenols from cocoa can increase the quantity of Bifidobacteria and lactobacilli in humans, as well as reduce the quantity of Clostridia.
Furthermore, these changes in the microbiota are associated with lower levels of triglycerides and C-reactive protein, a marker of inflammation The polyphenols in red wine have similar effects Probiotics are live microorganisms, usually bacteria, which exert a specific health benefit when consumed. Probiotics don't permanently colonize the intestines in most cases. However, they may benefit your health by changing the overall composition of the microbiota and supporting your metabolism A review of seven studies found that probiotics have little effect on the gut microbiota composition of healthy people.
However, there is some evidence to suggest that probiotics may improve the gut microbiota in certain diseases A review of 63 studies found mixed evidence regarding the efficacy of probiotics in altering the microbiota.
However, their strongest effects appeared to be restoring the microbiota to a healthy state after being compromised Some other studies have also shown that probiotics don't have a big effect on the overall balance of bacteria in the intestines of healthy people. Nevertheless, some studies have shown that probiotics can improve how certain gut bacteria function, as well as the types of chemicals they produce The best way to maintain a healthy microbiota is to eat a range of fresh, whole foods, mainly from plant sources like fruits, veggies, legumes, beans and whole grains.
Prebiotics are types of fiber that feed your friendly gut bacteria, leading to all sorts of benefits. Here are 19 healthy foods rich in prebiotics. Having healthy gut bacteria is important for your health. However, many diet, lifestyle and other factors can negatively affect the health of your gut.
Kombucha is a type of fermented tea that has many health benefits. Here are 8 ways that kombucha can improve your health, backed by science. Resistant starches are starch molecules that resist digestion, functioning kind of like fiber. Studies show that they have many health benefits. Both probiotics and prebiotics help keep your gut bacteria healthy, but serve different functions. This article explains the difference.
A probiotic is a live microorganism that provides health benefits when consumed. This article explains everything you need to know about probiotics. Impaired gut health may cause unwanted substances to "leak" into the bloodstream.
This causes inflammation, which may be driving chronic metabolic…. Fiber is indigestible material found in foods. Studies show that fiber has various health benefits, including weight loss and improved digestive…. Artificial sweeteners may provide sugar and calorie-free sweetness, but their health effects are controversial.
What should I eat for a healthy gut?
K imchi, kombucha, sauerkraut, miso and kefir — all fermented foods and drinks — have been around for centuries, but suddenly they are all the rage. The reason? They are supposedly packed full of gut-healthy microorganisms, and we are finally waking up to just how much the trillions of microorganisms that live in our guts AKA the gut microbiome contribute to our mental and physical health.
How do you know if you have poor gut health? Diondra Atoyebi, D. A healthy gut means you have a good balance of bacteria, or microbes, in your gastrointestinal tract. These microbes help the body:.

Gut-related messages are everywhere, both in popular media and in science too. Here we provide a back-to-basics introduction on the gut microbiome, and why it is important to your health. These microorganisms, mainly comprising bacteria, are involved in functions critical to your health and wellbeing. These bacteria live in your digestive system and they play a key role in digesting food you eat, and they help with absorbing and synthesising nutrients too. Gut bugs are involved in many other important processes that extend beyond your gut, including your metabolism, body weight, and immune regulation, as well as your brain functions and mood. Your gut began to populate with bacteria very early in life. Indeed, some research suggests that this begins while we are still in the womb.
Magical microbes – how to feed your gut
Collectively, they are known as your gut microbiota, and they are hugely important for your health. However, certain types of bacteria in your intestines can also contribute to many diseases. Interestingly, the food that you eat greatly affects the types of bacteria that live inside you. Here are 10 science-based ways to improve your gut bacteria.
But we are by no means permanently attached to a diagnosis of Major Depression Disorder if that is what Mom and Dad kindly handed down. Each of us also has a complex collection of bacteria living in our guts — our distinct microbiome — that also has genes. Since there is much we can do to shape the environment within our guts, we have control over our microbiota and can compensate for the lack of control we have over our human genome.
Gut Food - 15 Foods For Good Gut Health
As many countries urge populations to stay at home, many of us are paying more attention to our diets and how the food we eat can support our health. To help sort out the fact from the fiction, BBC Future is updating some of our most popular nutrition stories from our archive. Our colleagues at BBC Good Food are focusing on practical solutions for ingredient swaps, nutritious storecupboard recipes and all aspects of cooking and eating during lockdown. But the science has a way to go before we know exactly what nutrition is best for your gut.
Confused about what to eat and what not to eat? Live yoghurt is an excellent source of so-called friendly bacteria, also known as probiotics. Look out for sugar-free, full-fat versions and add your own fruit for a tasty breakfast. Yoghurt drinks can contain high numbers of bacteria that are good for the gut, far more than you would find in a normal yoghurt. Do be mindful though as they can have a high sugar content. This probiotic yoghurt drink is made by fermenting milk and is packed with good bacteria.
What’s an Unhealthy Gut? How Gut Health Affects You
In many ways, your gut bacteria are as vast and mysterious as the Milky Way. About trillion bacteria, both good and bad, live inside your digestive system. Collectively, they're known as the gut microbiota. Science has begun to look more closely at how this enormous system of organisms influences—and even improves—health conditions, from heart disease to arthritis to cancer. But understanding how the gut microbiota works, and how you may benefit, can be daunting. Elizabeth Hohmann of the infectious diseases division at Harvard-affiliated Massachusetts General Hospital.
The microbes in your gut can help you to get thinner, be happier and live longer. By Prof Tim Spector. Your gut microbiome is a vast community of trillions of bacteria and fungi that inhabit every nook and cranny of your gastrointestinal tract, and have a major influence on your metabolism, body weight, propensity to illness, immune system, appetite and mood.
What is the Gut Microbiome?
By: Alison Moodie March 23, Are you feeling down? Are you dealing with skin problems?
The incredible complexity of the gut and its importance to our overall health is a topic of increasing research in the medical community. Numerous studies in the past two decades have demonstrated links between gut health and the immune system, mood, mental health, autoimmune diseases , endocrine disorders, skin conditions, and cancer. A person has about to different species of bacteria in their digestive tract. While some microorganisms are harmful to our health, many are incredibly beneficial and even necessary to a healthy body.
