What are fermented foods?

We often hear about fresh foods being the best for us (and rightly so). But these days, we’re hearing more and more about the health benefits of fermented foods. Examples of fermented foods are:

  • sauerkraut
  • kimchi
  • pickles
  • yogurt
  • tempeh
  • and miso

What is lacto fermentation?

Lacto-fermentation of foods is an ancient art. It’s been practiced for thousands of years as a way to preserve different foods. The process breaks down many vitamins and other nutrients into more easily digestible forms. Additionally, lacto-fermentation might increase the palatability and nutritional quality of food.

The majority of lacto-fermented foods are produced from raw veggies without the use of heat. Lacto-fermentation may appear complicated and perplexing to those who are unfamiliar with it. It’s really not! And no, it has nothing to do with dairy.

Lactic acid is the acid produced by lactic bacteria. On the surface of all fruits and vegetables, there are good bacteria such as Lactobacillus. These bacteria convert the sugars in food into lactic acid in an anaerobic (oxygen-free) environment.

It’s this compound that inhibits harmful germs while also acting as a preservative, which protects the vegetables from spoilage. In other words, lacto fermentation is the culturing of foods with lactic acid bacteria.

Health benefits of fermented foods

More than 1012 microorganisms dwell in the human digestive system. This complex ecosystem protects against infections, absorbs nutrients from meals, and controls the immune system.

The gut microbiota is also highly resilient; however, several factors such as antibiotics, stress, and illness may disrupt it, resulting in dysbiosis. The capacity of food and dietary components to modify the gut microbiome, redress dysbiosis, and enhance human health is now well-established

Dysbiosis generally means “disbalance” of the commensal microbiota (bacterial community). This usually implies a shift in the relative abundance of specific bacterial species within the digestive system. Disruption in the bacterial community is often associated with illness, specifically autoimmune conditions and metabolic diseases like diabetes, multiple sclerosis, and inflammatory bowel disease.

Many things can influence the types of bacteria in your gut. Fibres and prebiotics that are fermented can help certain types of bacteria grow. You can also change the types of bacteria in your gut by taking probiotics.

Probiotics, however, are short-term dwellers in the microbiome. Therefore, you need to be taking them frequently to reap the benefits.

Lacto fermented vegetables involve a process that’s thought to help increase the bioavailability of certain nutrients. This means they are more easily taken up in our bodies.

The process also destroys some anti-nutrient components of certain raw foods, such as oxalates and phytic acids. Antinutrients have been shown to reduce the body’s ability to absorb essential nutrients.

Are fermented foods good for gut health?

Fermented foods are thought to be good for gut health.

Scientists believe that the possible health benefits of fermented foods are because they are a source of probiotics; which might support gut health.

Recent studies suggest that microbes in our gut play a role in diabetes, heart disease, and immune function.

While there is compelling evidence from test tube studies that fermented foods are helpful for disease prevention, there aren’t enough clinical studies showing that fermented foods are good for gut health.

How to ferment veggies

Using raw vegetables as the starting ingredient increases the vitamin and mineral content of fermented vegetables.

Fermented vegetables made with raw veggies have a higher vitamin and mineral content than those prepared in other ways. Grating, shredding, chopping, slicing, or leaving whole are just a few methods to prepare the ingredients for fermentation. It’s entirely up to you. Carrots, radishes, and beets are dense vegetables, and lactic acid can penetrate these veggies more easily when chopped.

I picked some of my favourite colourful ingredients for this fermented veggies recipe to get a range of nutrients. Some I chopped, while others I left whole.

Preparing salt water and vegetables:

An empty mason jar with vegetables in a tray in the background.
Step 1: Start with a clean, dry 2-quart glass jar. Wash the jar and lid in warm soapy water.

Step 2: Prepare salt water by combining sea salt with water. Use spring, distilled, or filtered water if you can as most tap water contains chlorine to kill bacteria.

Step 3: Stir the salt and water, ensuring the salt granules are fully dissolved.

Step 4: Prepare the vegetables by washing them in cold un-chlorinated water. Remove any visible dirt and debris. Add the chopped vegetables to the jar.

Setting up for fermentation:

Step 5: Pour salt water into the jar until it is full. Ensure the vegetables are submerged in the brine. If necessary, you can top up with more water and stir. Place the lid firmly on top.

Step 6: Remember to label the jar with the date you started the fermentation to prevent confusion. It’s important not to wing it and guess. A simple post-it note does the trick.

How do I know fermentation is complete?

I leave my jar out on the counter for 2-3 days (around 72 degrees Fahrenheit), then transfer it to the fridge. The following signs will tell you whether your veggies have fermented successfully:

Step 7: Look for bubbles. The lactic acid fermentation process produces bacteria that release gases when they feast on vegetables. These gases are often visible as bubbles after a few days at room temperature. Plus, it’s time to trust your nose; a sour, vinegary odour is released when the jar is opened after a few days.

Step 8: Taste the tanginess! Tasting your veggies will also confirm if they are ready to be moved to the fridge. They should taste tangy and delicious!


To store lacto fermented vegetables, you need a cool and dark place. The ideal temperature is between 35 and 40 degrees Fahrenheit. You can either use a refrigerator or a root cellar. Fermented foods need to be kept in a dark place because light will deteriorate the nutrients in your veggies.

Tips for novice fermenters

  1. Use salt that is free of iodine and/or anti-caking agents, which can inhibit fermentation.
  2. In the summer, the veggies will ferment faster than in the winter, which might take up to 7 days.

Food safe storage and handling

Ensure proper hygiene by using clean hands when reaching into the jar to prevent the introduction of contaminants. Remember, the top of your vegetables (in the jar) is exposed to oxygen, which can promote the growth of yeast and mould – but everything below the brine should be fine because of an oxygen-free environment.

Therefore, regularly inspect the fermented vegetables for any indications of spoilage, such as unusual odours, mould development, or changes in color. If any issues are observed, promptly discard the affected portion.

Similarly, use a clean spoon when serving the fermented vegetables rather than consuming directly from the jar.

Once stored in the refrigerator, these will keep for a couple of months.

Which vegetables can be fermented?

The veggies that can be fermented are primarily vegetables with a high water content like cucumbers, carrots, zucchini, and green peppers. These types of veggies are the most readily fermented as their sugars will readily dissolve in the brine. It is possible to ferment other vegetables, but this process takes longer and results in a more sour-tasting result.

Top Tips For Making Easy Fermented Vegetables

  1. Rinse the vegetables in un-chlorinated water rather than tap water.
    Use salt that is free of iodine and/or anti-caking agents, which can inhibit fermentation. Chlorinated water can inhibit fermentation, so use spring, distilled, or filtered water if you can.
  2. Wash your vegetables thoroughly under cold water
  3. Use a 2 quart jar that’s clean and dry
  4. Salt type is important. Don’t use salt with iodine – iodine can inhibit fermentation
  5. Ensure that all the vegetables are fully submerged in the salt water. You can add some more on top to cover the vegetables completely (yes, I will add more!)
  6. Label the jar with the date when you started fermentation. That way, you’re not left to guess
  7. In the Summer, the vegetables will ferment faster versus the Winter – which could take up to 7 days
  8. Remember, the top of your vegetables (in the jar) are exposed to oxygen, which can promote growth of yeast and mold – but everything below the brine should be fine because of an oxygen-free environment. If you notice any mould, discard the layer.
  9. Always use a clean spoon when serving, versus eating out of the jar. You want to avoid contaminating the entire batch with germs from your mouth
  10. Once in the fridge, these will keep for several month. Enjoy
