Top Probiotics Benefits That Are Worth Knowing
Published | 6 min read
Probiotics benefits, such as having an easier time going to the bathroom, are not limited to your gut. Read on to learn more about why adding good bacteria to your diet can be beneficial for other areas of your body, too.
Probiotics benefits may start with your digestive tract, but they expand well beyond this area of your body. In fact, your gut is so important for overall health that it’s been referred to as the “second brain” by scientists.
Benefits of probiotic bacteria include brain and immune support. They may even help improve blood sugar levels. But does that mean you should start taking a daily probiotic supplement?
In this guide, our experts break down the top probiotic benefits for your health, how to get more in your diet, and what your gut says about your overall health.
What Are Probiotics?
The human body is a wondrous thing. It’s made up of billions of tiny elements that keep us alive, for example, cells, tissues and microbiome, among others. The microbiome itself consists of trillions of microbiota, such as viruses, fungi and bacteria. While they exist throughout the body, many of them live in the intestines.
We’re used to associating bacteria with a kind of infection that makes us feel ill, but this is not entirely correct. There are about 50 trillion intestinal or gut bacteria, and not all are bad. In fact, we need some of them to be healthy.
Generally, there are two kinds of gut bacteria. They can be either bad (pathogenic) or friendly (symbiotic). When a person is born, the kinds of microbiota in their body, including their gut bacteria, are determined by their genes. But as they grow older, it can change according to their environment, medication use, exercise and diet.
Probiotic Benefits For General Health
The health benefits of friendly gut bacteria are:
1. Breaking down toxic food compounds
2. Synthesizing amino acids and vitamins, like vitamins B and K
3. Protecting the body from harmful pathogens in contaminated drinks or foods
4. Boosting the immune system
As mentioned above, our gut bacteria changes as we get older. While doing so, they affect our bodies in several ways. For example, there is evidence that the shifts in gut bacteria’s structure can accelerate ageing.
Furthermore, studies have found that gut bacteria can impact our hearts and brain. Not only does our gut stimulate the immune system, but it also interacts with the two vital organs. This is why our gut can control our physiology, from our blood pressure, metabolism and mood. It has also been linked to cardiovascular diseases and type 2 diabetes. Additionally, one study discovered that gut bacteria can also affect our depressive tendencies.
Prebiotics And Probiotics Benefits
We know now that friendly gut bacteria are beneficial for our health in more ways than one. Therefore, it’s essential to help them combat bad gut bacteria by feeding them the right kind of food.
All in all, avoiding processed foods and choosing a balanced diet featuring fruits and vegetables are good for our body, so the same principle should apply to our gut. At times, though, we need prebiotics and probiotics.
Prebiotics Benefits
Prebiotics are defined as a group of nutrients that feed the gut bacteria. Once digested by the gut bacteria, their by-products become short-chain fatty acids (SCFA) that lower the pH of the large intestine. A lower pH will then help prevent the bad bacteria from growing.
Prebiotics can be found in:
1. Carbohydrates
2. Inulin (fibre in plant-based foods, like agave, wheat, onion, garlic, asparagus)
3. Oligosaccharides (garlic, onion, wheat, legumes)
4. Resistant starch (chilled potatoes, beans, legumes, green bananas, fried rice, oats, barley)
5. Pectic Oligosaccharide or POS (sugar beet pulp, apple pomace, olive, passion fruit peels, citrus)
6. Cocoa-derived flavanols
7. Human’s and cow’s milk
8. Seaweeds and microalgae
Probiotics Benefits
Probiotics are live bacteria and yeasts found in some foods. When consumed, they can help the good gut bacteria to grow.
Probiotics can be found in:
1. Yoghurt
2. Probiotic supplements
3. Fermented foods (tempeh, kimchi, miso)
Probiotics aren’t created equal; different strains have different effects on the body. Even so, probiotics have the potential to reduce symptoms of the following conditions or diseases:
1. Diarrhea: Research has shown that probiotics may relieve diarrhea faster.
2. Irritable bowel syndrome (IBS): Probiotics proves to be effective and safe to treat symptoms of IBS.
3. Ulcerative colitis (chronic IBS): There is evidence that probiotics can improve the symptoms of ulcerative colitis, but the research is still limited.
4. H. pylori infection: The infection is usually treated using antibiotics, and probiotic supplements can enhance their effectiveness and reduce the severity of the side effects. The study also concluded that probiotics can also maintain friendly gut bacteria.
5. Urinary tract infections: Probiotic Lactobacillus is considered part of natural support for symptoms of urinary tract infections.
6. Recurrence of bladder cancer: One study suggests that probiotics can act as a biomarker and provide a therapeutic effect in bladder cancer.
7. Side effect of colon removal surgery (pouchitis): While more evidence is needed, probiotics may help prevent pouchitis.
More than improving digestion, gut bacteria also affects the heart and mind. This knowledge adds weight to the saying that goes, “You are what you eat.” Improving the friendly gut bacteria, which is one of the benefits of probiotics, is a way to reach overall health and well-being.
You can get more probiotics into your diet by eating more yogurt or yogurt powder, taking a probiotic supplement, and eating more fiber.
Probiotics Benefits, From A TCM Perspective
In Traditional Chinese Medicine (TCM), good gut health is vital as our food intake is ultimately converted to ‘qi’ (vital energy) and blood elements that are crucial for the nourishment of the mind and body. From TCM’s perspective, the primary organ responsible for maintaining a healthy and functioning digestive system is the spleen.
Besides digesting food, the spleen and stomach also take on the combined role of breaking down food into nutrients and subsequently converting them into the vital ‘qi’ and blood elements. It is essential to maintain a healthy spleen – the source of ‘acquired constitution‘ so that our body has the energy needed to carry out daily activities.
An unhealthy, disrupted gut often presents with gastrointestinal conditions, such as diarrhea, constipation, bloating and gas, which are symptoms similar to patients with an unhealthy spleen. In TCM, this is explained by the deficiency of the spleen ‘qi’.
Depending on the individual’s body constitution, this ‘qi‘ deficiency can manifest as different symptoms in any organ. That can result in the stagnation of the flow of ‘qi’ and blood, also known as stasis. In the spleen, stasis can result in symptoms such as bloating, gas and constipation. A prolonged stagnation of the spleen ‘qi’ often results in an accumulation of internal dampness resulting in diarrhea and a feeling of general lethargy.
Individuals should consult a TCM physician to better understand their body constitution and receive personalized treatments for their ailments. With the right diagnosis and treatment, TCM can repair and restore the gut environment to maintain a healthy and active gut bacteria colony and improve overall gastrointestinal function.
