Health Benefits of Fermented Foods

Fermented foods have been part of traditional diets for generations. They can provide nutrients, flavour, and living cultures, depending on how they are prepared and stored.

This guide explores what fermented foods may offer, what research is still examining, and how they can fit into a balanced diet.

Nutritional Value

Fermented vegetables can retain many of the nutrients found in fresh vegetables. Their nutritional value depends on the ingredients, fermentation method, storage, and serving size.

Living Cultures

Some fermented foods contain live microorganisms when they have not been heat-treated after fermentation. The amount and type can vary from one food and batch to another.

Probiotics and the Gut

Some live microorganisms in fermented foods may support the gut microbiome, but effects can differ between foods and from one person to another. Research continues to study which strains and serving amounts are most helpful. Regardless, the fermented foods will generally support the gut microbiome.

Digestibility

Fermentation changes some natural compounds in food and may make certain foods easier for some people to digest. Individual responses vary, especially with salty, acidic, or high-fibre foods.

Salt and Serving Size

Fermented vegetables can contain a significant amount of salt. Enjoy them in portions that fit your overall diet, especially if you are limiting sodium.
