The lowdown on fermented foods

There’s no denying that considering one’s gut health is highly important when it comes to healthy eating. Many everyday day foods are good for gut health. These foods include vegetables, fruits, whole grains, nuts, seeds, fish and extra virgin olive. However, there is another category of foods that can promote gut health: fermented foods. 

Humans have enjoyed fermented foods—from wine, beer, and vinegar to pickles, olives, yoghurt, and cheese—for millennia. Before using fridges, people used fermenting to preserve foods. But can fermented foods make your gut healthier? The short answer is yes. In this blog, I will break down the evidence to support this theory. 

What are fermented foods?

Fermented foods go through a process called “Lacto fermentation”, where natural bacteria feeds on the starches and sugars in the food to create lactic acid. 

For vegetables, they soak in their own juice or saltwater, allowing bacteria to grow. This bacteria eats the sugar in the vegetables, creating lactic acid. The end result is a fermented product that has a tart and slightly acidic taste. The fermentation process preserves the food and its nutrients. It also creates beneficial enzymes, b-vitamins, Omega-3 fatty acids, and various strains of probiotics.

Types of fermented foods

Kimchi

Kimchi is a popular dish in Korea, which is essentially fermented cabbage. Some people also make kimchi from other vegetables, such as radishes.

Tempeh

Tempeh is made from fermenting soybeans. The soybeans are then pressed into a compact cake. It is a high-protein meat substitute that is firm, but chewy. You can bake it, steam or sauté it before adding it to dishes.

Natto

Natto is a staple probiotic in traditional Japanese cuisine. Like tempeh, it uses fermented soybeans. It has a very strong flavour and slippery texture.

Kombucha

Kombucha is a fermented tea that’s tart, fizzy, and flavourful. It contains either black or green tea and contains potent health-promoting properties.

Miso

Miso is a common seasoning used in Japanese cuisine. It is made by fermenting soybeans with salt and koji, a type of fungus.

Sauerkraut

Sauerkraut is a popular condiment that consists of shredded cabbage fermented by lactic acid bacteria. It’s low in calories and contains plenty of vitamin C, vitamin K and fibre, and vitamin K. 

Probiotic yoghurt

Probiotic yoghurt is made by fermenting milk with lactic acid bacteria. It’s high in many important nutrients, including calcium, potassium, phosphorus, riboflavin, and vitamin B12. 

Kefir

Kefir is a milk drink that you make with yeast fermentation and bacteria. Also, the beverage is tangy and thick and tastes like yoghurt.

The Benefits of fermented foods

Fermented foods contain probiotics for better gut health

Fermented foods can improve gut health due to the beneficial bacteria they contain. Kefir and Kombucha, in particular, helps balance out the good and bad bacteria in your digestive system and can aid digestion.

Boosts Your Immune System

The bacteria found in your gut have a significant impact on your immune system. Due to their high probiotic content, fermented foods can boost your immune system and reduce your risk of infections like the common cold. 

Absorbs food better

The improved balance of gut bacteria and digestive enzymes ensure you’re absorbing as many nutrients as possible. Eating a varied diet and absorbing key nutrients properly will be a great boost for your overall gut health.

Preserves food easily

As hard as we might try, we all end up finding some rotten vegetables in our fridge every so often. Luckily, fermented foods last much longer, since the fermentation process prevents foods from going off. This means you can store foods for much longer without losing any nutrients. 

Where to find fermented foods

I get most of my fermented food products from Jacksons Real Food Market and Eatery in Bryanston. Their Kimchi is my favourite! Also, check out your local supermarkets and health stores for fermented products.
