Probiotics and Gut Health: What You Should Know

Your gut is home to trillions of bacteria that influence digestion, immunity, and even mood. Here is what probiotics are and how they help keep that balance.

Check with a doctor before choosing a specific probiotic supplement

You have probably heard the term “gut health” a lot lately, and it is not just a passing trend. Your gut hosts trillions of bacteria, some helpful and some less so, and this delicate balance affects digestion, immunity, and nutrient absorption — and is increasingly linked to mood too, through what is known as the gut-brain axis.

What exactly are probiotics?

Probiotics are live, beneficial bacteria that, when consumed in sufficient amounts, help support a healthy balance in the gut. They differ from prebiotics, which are essentially fiber that feeds the beneficial bacteria already living in your body.

Natural food sources of probiotics

Yogurt labeled with “live and active cultures.”
Buttermilk and kefir.
Naturally fermented pickles like sauerkraut.
Kimchi and miso from Asian cuisine.

Do not forget prebiotics

Garlic, onions, bananas, and oats are fiber-rich foods that feed beneficial bacteria, so combining probiotic and prebiotic sources gives your gut a more balanced environment. If you are considering a probiotic supplement, check with your doctor to choose the right strain for your situation.
