Natural Probiotics and their Benefits
What are Probiotics?
The term probiotic means 'pro-life' or ‘for life’ in Greek. Probiotics are live microorganisms which are present naturally in our surroundings, our skin, digestive tract, nasal tract, urinary tract, genital area, mouth, etc., Not all bacteria are harmful, some bacteria are not only beneficial but are needed for some of our body functions. Probiotics are the good microorganism that are beneficial to our heath and have suddenly become the rage. Natural probiotics are found in foods that are fermented. The use of fermented foods by man has been recorded since biblical times. Studies have shown that consumption of probiotic foods aids in digestion and assimilation of food. It also helps to maintain and establish the delicate balance of intestinal bacteria and health in general.
Probiotic Food - History
Fermentation has been a favourite method of processing and preserving food for centuries. It has been an effective way to preserve fruits and vegetables for longer periods. Grains and fruits have been brewed into beverages through the process of fermentation. People have been using different forms of yeasts for baking foods. Today a huge sector of the food industry, namely the beverage industry depends on the processes of fermentation for its product range. It has been known for centuries that fermented foods are good for health.
Bacteria and their action in our body
Our digestive tract contains trillions of bacteria, some of which are bad, while others are vital for the optimal functioning of the body. The good bacteria help to balance the action of the bad bacteria which cause infections and diseases. Good bacteria in the intestines could get killed or severely reduced due to various reasons like - taking antibiotics, aging, illnesses, food poisoning, excessive consumption of processed foods, consuming foods that are low in fibre, alcohol and drug abuse etc. People often suffer from diarrhoea and other illnesses when the good bacteria in the gut get depleted. Consumption of natural probiotics such as yoghurts, fermented milk drinks or other fermented foods helps restore the balance in the gut.
How do probiotics work?
- Probiotics inhibit the growth of bad bacteria in the body.When natural probiotics are consumed they colonize the gut and reduce the activity of the bad bacteria.
- They fight against bad bacteria. In other words they are anti microbial. They help increase our immunity and make our body more resistant to diseases and infections
- They improve the secretion of digestive enzymes. They help improve digestion.
- They increase the production of lactic acid and help regulate the pH balance in the intestines and other parts of the body.
- Probiotics in the gut can ferment fructooligosaccharides which results in a reduced pH balance.The reduction of pH balance increases acidity in the gut enabling better absorption of calcium and making it easy for the calcium to get into the blood stream.
- Consumption of probiotics promote favourable acidic pH which facilitates the absorption of protein and minerals like calcium, copper, magnesium, iron and manganese.
- They have been known to have anti inflammatory properties
Facts about Probiotics
The concept of probiotics evolved from a the hypotheses of Nobel Prize winning Russian scientist, Elie Metchnikoff (Metchnikoff 1908), who was then a professor with the Pasteur Institute, Paris. He suggested that the longevity of Bulgarian peasants was a result from their high consumption of probiotics which replaced the bad bacteria in their gut.

Natural Probiotic Foods
Studies have shown that probiotic supplements especially capsules and sachets do not necessarily contain the bacteria stated on the labels or they may not be active cultures. How then do you get dependable natural probiotics? You can make your own. You do not have to spend too much money on yoghurt or any of these probiotic foods.

Yogurt/curd is an excellent probiotic which has been known for its beneficial properties for centuries. People with lactose intolerance can usually tolerate the lactose from yogurt/curd better than from milk. Fermented lactose is much easier to digest
Making yogurt/curd at home is easy. Warm a bowl of pasteurised milk. It should be tepid. Add two tablespoons of organic unsweetened yogurt and leave it in a warm place. This is a live culture, which could be used to make fresh yogurt every day. You would never have to go back to the store to buy yogurt again.

This is a common drink during the hot summer season to prevent diarrhoea and other infections of the digestive system. A pinch of asafoetida, salt, curry leaves, etc., are added to make it more flavourful.
