25 Best Probiotic Foods for Better Gut Health

Probiotic foods help to repopulate your gut microflora. These are millions and billions of beneficial microorganisms that naturally reside in your intestine or gut. They protect us from many ailments and keep us healthy (1). 

Bestowed with numerous health benefits, probiotic foods are sure shot solutions to several problems that we face today. These good bacteria help maintain the integrity of your gut, keep your inflammation down and kill pathogens. They have antiviral properties as well. They help recycle and modify bile salts that protect you from bacterial infection.

Keeping all this in mind, we have listed the 25 best probiotic foods from all over the world. They are super healthy, affordable, and easily available.

What are probiotic foods?

Our body is home to both good and bad bacteria (pathogens). A delicate balance is always maintained amongst them that ensures we are healthy.

However, certain conditions such as prolonged illness, antibiotic consumption, and continuous intake of refined/processed foods, can jeopardize this balance. The good bacterias reduce in number while the colony of bad bacteria increases. This results in illness and bad health.

Probiotic foods help restore this balance. It fights off the bad microbes. These foods survive the harsh environment of the stomach and reach the intestine intact.

Probiotic food helps you make vitamins such as B-vitamins: B1, B6, and B12; biotin and vitamin K2. They support the absorption and metabolization of essential nutrients, help maintain your gut health, boost your immunity, keep your skin glowing and the list goes on. 

Therefore, if your body doesn’t contain sufficient amounts of these good bacteria, you can face massive nutritional deficiency in addition to other health-related problems.

The most common bacteria in probiotic food is Lactic acid bacteria (LAB) (2). The other common strains of probiotics are:

  • Bifidobacterium
  • Lactobacillus
  • Saccharomyces boulardii, which is a type of yeast
  • Enterococcus faecium

There is a wide range of probiotic foods that you can easily incorporate into your diet for a healthier option.
