The Secret Connection Between Probiotics and Gut Health
Probiotics have been touted as a cure-all for everything from digestive upset to colds and flu. But what are they, really? And how do they work?
What are probiotics?
Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. They are often called “good” or “friendly” bacteria because they help keep your gut healthy.
Probiotics are found naturally in some foods, such as yogurt, kefir, sauerkraut, and kimchi. They can also be taken as supplements, either in pill or powder form.
How do probiotics work?
Probiotics work by restoring the natural balance of bacteria in your gut. Your gut is home to trillions of bacteria, both good and bad. When the balance of these bacteria is disrupted – by antibiotics, illness, or poor diet – it can lead to digestive problems, such as diarrhea, bloating, and constipation. Probiotics help to replenish the good bacteria and keep the bad bacteria in check, which can lead to improved digestion and overall health.
But it’s not just your gut that benefits from probiotics. There is evidence that probiotics may also boost your immune system, improve skin health, and even help with weight loss.
What are the best sources of probiotics?
The best sources of probiotics are naturally fermented foods, such as yogurt, kefir, sauerkraut, and kimchi. When looking for probiotic-containing foods, it’s important to read the label and make sure they contain live and active cultures.
If you prefer to take probiotics as supplements, there are many different types and strains available. Look for supplements that contain a variety of strains, as different strains may have different benefits.
Can probiotics improve gut health in people with digestive disorders?
There is evidence that probiotics can help improve the symptoms of certain digestive disorders, such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). For example, a 2014 review of 35 studies found that probiotics may help alleviate symptoms of IBS, such as bloating, gas, and abdominal pain. And a 2015 study found that a specific strain of probiotics helped reduce inflammation in people with ulcerative colitis, a form of IBD.
However, it’s important to note that probiotics are not a cure-all for digestive disorders, and should not be used as a replacement for medical treatment.
Are there any risks to taking probiotics?
For most people, probiotics are safe and well-tolerated. However, in some cases, they can cause mild side effects, such as gas and bloating. In rare cases, probiotics can lead to more serious infections, particularly in people with weakened immune systems.
If you are considering taking probiotics, it’s always a good idea to talk to your doctor first, especially if you have a medical condition or are taking medications.
The Bottom Line
Probiotics can be a valuable addition to a healthy diet and lifestyle. They work by restoring the natural balance of bacteria in your gut, which can lead to improved digestion and overall health. However, it’s important to choose probiotic-containing foods and supplements carefully, and to talk to your doctor before taking probiotics if you have a medical condition or are taking medications.
