Fermentation is an ancient technique for preserving food. Today, the process is still used to produce foods such as wine, sauerkraut, yogurt, and kombucha tea.
According to the health website Healthline (USA), fermented foods are rich in probiotics and have many health benefits, including better digestion and improved immunity.
Fermented foods may help boost the immune system
What are fermented foods?
Fermentation is a natural process in which microorganisms such as yeast and bacteria convert carbohydrates such as starch and sugar into alcohol or acid. The alcohol or acid then acts as a natural preservative, giving fermented foods their characteristic sour and tangy taste.
Fermentation also promotes the growth of beneficial bacteria. Probiotics help improve immune function, digestive health, and cardiovascular health. Therefore, adding fermented foods to your daily diet can help improve your health.
Benefits of fermented foods
1. Good for the digestive system
Probiotics produced during fermentation can help restore the balance of bacteria in the gut and may alleviate some digestive problems. According to studies, probiotics can reduce the uncomfortable symptoms of irritable bowel syndrome.
Furthermore, fermented foods may also reduce the severity of diarrhea, bloating, gas and constipation.
Fermentation also helps break down nutrients in foods, making them easier to digest than non-fermented foods.
2. Strengthen immune system health
In addition, the bacteria that live in the gut have a significant impact on the immune system. Due to their high probiotic content, fermented foods can help boost the immune system and reduce the risk of infections such as the common cold.
Additionally, consuming foods rich in probiotics can also help the body recover faster when sick. Many fermented foods are rich in vitamin C, iron, and zinc - ingredients that help strengthen the immune system, according to Healthline .
Many studies also show that fermented foods help reduce symptoms of anxiety and depression, aid weight loss and support heart health.
Notes when using fermented foods
Fermented foods are considered safe for most people. However, some people may experience side effects.
Due to the high probiotic content in fermented foods, some people may experience temporary gas and bloating when eating these foods.
Additionally, some products may contain high levels of sugar, salt, and fat. Therefore, consumers should carefully read the nutritional information before choosing to buy fermented products.
If fermenting at home, the processor needs to ensure strict adherence to the recipe, temperature, and fermentation time to ensure safety during consumption.
