What Are Probiotics?

According to the World Health Organization, probiotics are living microorganisms that when consumed in sufficient numbers can provide excellent health benefits that go beyond basic nutrition. Probiotics are cultures that have been shown to provide specific health benefits such as supporting digestive and immune health and contributing to the maintenance of a balanced gut microbiota, which is important for the proper functioning of the digestive system and the entire body.

Top 5 Benefits of Probiotics

 

Probiotics are live bacteria (found in foods like kefir, yogurt, and kombucha) are essential for good gut health. And if you consider that your microbiome (all of the bacteria in your body) is a mix of good and bad bacteria (like the kind that makes you sick), it’s important to have enough of the good bacteria so your body will function properly.

Probiotics do much more than alleviate stomach problems. While most people just thought of probiotics as beneficial for digestive health, your gut is connected to your entire body.

As a result? Emerging research suggests they help prevent a wide range of conditions, starting with these five.

1. Weight Loss

Taking a probiotic can lower your body weight and body mass index, Probiotics can also improve your blood sugar control and affect sensitivity to leptin (a hormone that helps regulate appetite.) This is key for anyone struggling with type 2 diabetes.

2. Skin Conditions

Skin conditions like psoriasis, eczema, and rosacea can be troublesome, to say the least, but some studies suggest that the right strains of probiotics can help. It reverts to the whole idea of inflammation. And since some skin conditions, like other health issues, stem from inflammation, minimizing it can be a skin savior.

3. Immune Health

Tired of feeling sick and run down? Research has shown less of an occurrence of upper respiratory infection after the use of probiotics,” And it makes sense why: Probiotics are a better type of bacteria, they can help prevent infection. Making sure you have a better balance of bacteria can also ward off issues like the cold and flu.”

4. Allergies

A study published in the European Journal of Clinical Nutrition found that allergy sufferers who took a supplement of a probiotic called B. lactis once a day for 8 weeks were far less sniffly two months down the road than those who didn’t. People who took probiotics also had decreased levels of pro-inflammatory markers, the researchers say. That could be because probiotics alter the permeability of the intestinal wall, and help to keep pro-inflammatory compounds from entering the bloodstream, says nutritionist Molly Kimball, R.D.

5. Mood Disorders

In a study of 40 people without mood disorders, those who took a probiotic supplement every night for 30 days felt happier and reported feeling generally happier and less bothered by life’s problems than those who took a placebo. Other research suggests that probiotics can help lower levels of depression, stress, and anxiety.
