How To Ferment Vegetables

In this article, we are sharing how to ferment vegetables and the benefits that are included when adding fermented foods to your plant-based diet. 

Many of our favourite plant-based foods are fermented, such as cashew cheeses, sourdough bread, vegan kimchi, sauerkraut, sour pickles and tangy fermented vegetables. Fermented food complements a variety of our favourite dishes and are a delicious garnish as well!

Fermenting is surprisingly simple when it comes to vegetables. Still, you can surely find the more complex fermenting processes when it comes to a bold fermented cashew cheese recipe or tedious sourdoughs.

The fermenting process is unique and will quickly become a household favourite as a topping, garnish or delicious addition to many plant-based meals. 

Fermented foods have health benefits! The benefits include being an amazing source of healthy probiotics and prebiotic bacteria, eases digestion and allows nutrients to become more bioavailable. A healthy microbiome helps keep your gut bacteria balanced and protects against pathogenic bacteria. With that being said, fermented food is good for the gut! 

What are Prebiotics?

Prebiotics are the fermentable fibre that is naturally available in vegetables and fruits. For example, onion, bananas, artichokes, asparagus and onions. Prebiotics are important for nourishing the gut with beneficial bacteria. 

What are Probiotics? 

Probiotics are live bacteria that are full of health benefits when consumed. They are helpful to have in your diet to promote a healthy microbiome and are encouraged for people that experience digestion issues.

How to Ferment Vegetables

Lacto Fermentation is lactobacillus, which is healthy bacteria and has nothing to do with dairy! We are talking about lactic acid, and it prevents unhealthy bacteria from growing and preserves your vegetables. It is also what gives your delicious fermented veggies an excellent tangy and sour taste! Traditionally fermenting vegetables were done seasonally to keep preserved when a vegetable was out of season. 

In true Plant You fashion, lacto-fermented vegetables are simple to make right at home.
