Probiotics: What you need to know, plus 2 probiotic-boosting recipes

Probiotics: What you need to know, plus 2 probiotic-boosting recipes

Ask the experts

We usually think of bacteria as something that causes disease. But your body is full of bacteria – both good and bad. Probiotics are micro-organisms, such as bacteria and yeast, that have health benefits for the body. Probiotics, often called ‘good’ bacteria, are found in the intestines, where they help to balance the amount of good and bad bacteria, not only helping our digestive systems to function properly but also boosting our immune systems –  Lerato Radebe, dietitian and host of the new DSTV show Food Police and a spokesperson for the Association for Dietetics in South Africa (ADSA), gets to grips with the good guys.

Top of the crop

There are many types of bacteria classified as probiotics. They all have different benefits, but most of them can be categorised into two groups. Ask your doc about which might best help you:
Lactobacillus: Probably the most common probiotic, this is the one you’ll find in yoghurt and other fermented food. Different strains can treat diarrhoea and may help people who can’t digest lactose (the form of sugar in milk). In the human body, it lives in the intestines and the vagina.
Bifidobacterium: You will also find this probiotic in some dairy products. It may help alleviate the symptoms of IBS (irritable bowel syndrome).

Prebiotics vs probiotics

Probiotics are the actual live bacteria, whereas prebiotics are the non-digestible fibre in food that makes it conducive for the probiotics in your gut to grow. Sources of prebiotics include oats and bran; garlic, leeks and onions; legumes; artichokes; asparagus; and bananas.

Why is gut health so important?

Your intestinal tract is home to a diverse and complex microbial community and contains about 1 000 different bacterial species. This lively system plays a central role in your health and well-being, impacting your nutrition, bowel movements, immune system and metabolism.

A system off balance

When your gut microbiota is disrupted, it could potentially contribute to conditions such as obesity or malnutrition and IBS, as well as inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis. Immune-related conditions (such as eczema, allergies and the common cold) and general vaginal, urinary and oral health are connected to an imbalance of these important bacteria.

Signs of poor gut health

If you experience digestive discomfort frequently, you may have a problem with the balance of good and bad bacteria in your gut. Stomach pain, gas, bloating and diarrhoea are the common symptoms, but even conditions such as hormonal imbalances and anxiety have been linked to poor gut health.

Happy fermenting

Why is fermented food good for your tummy? In an oxygen-free environment, the Lactobacillus bacteria in vegetables and milk digest the natural sugars in these foods, creating their own acid, which then preserves the food. This is called lacto-fermentation. The lactic acid also kills off bad bacteria and feeds good bacteria in your gut.
