Exercise may improve more than just the look and diameter of your gut, according to a recent study. It may also increase the bacterial diversity within it, the study published in June in the journal Gut showed.
But is having more gut bacteria a good thing?
To give you an idea of the importance of your gut bacteria: At any given moment, you are housing more microbes than human cells. The largest populations of these microbes reside in the large intestine and the mouth, although you'll also find them elsewhere.
We begin collecting these microbes the moment we are born, and continue throughout our lives. In recent years, researchers have begun to pay more attention to these microbes and their impact on our health. [5 Ways Gut Bacteria Affect Your Health]
Here are just a few of the results showing the reasons why gut bacteria is good for more than just the gut.
1. Diabetes prevention: A daily dose of probiotics (good microbes) may help prevent weight gain and insulin resistance, according to a mouse study published in 2013 in the Journal of Biological Chemistry. Insulin resistance is a condition that can be a precursor to type 2 diabetes.
2. Improved urinary tract health: Probiotics may be beneficial in preventing urinary tract infections in women, according to a 2006 review of peer-reviewed studies published in the journal Drugs.
3. Allergy prevention or treatment: Women who take probiotics during pregnancy may reduce their child's chances of developing allergies, according to the evidence from available studies presented in a 2013 article in the journal Pediatrics.
4. Improved immunity: Probiotics may increase the activity of immune cells in the elderly, according to a study published earlier this year in the Journal of Nutritional Science.
5. Women's reproductive health: Five strains of Lactobacillius bacteria (a type of probiotics) may be effective in fighting overgrowths of Candida, a type of fungi that is often responsible for vaginal infections, according to a study published in February in the Journal of Applied Microbiology.
If you'd like to populate your gut with healthy probiotics, without taking a supplement, consider adding more of the following to your diet:
- Sauerkraut (from the refrigerated section)
- Miso
- Kimchi
- Pickles
- Tempeh
- Plain yogurt
