Question

Why is yoghurt a very important food material?

Answer 1

Hint: Yoghurt is a dairy product that results from the process of fermentation by certain bacteria. It is very essential for the body as it is very beneficial for the human digestive tract.

Step by step answer: Yoghurt is produced by the process of bacterial fermentation of milk. The group of bacteria which is involved in the preparation of yoghurt is known as yoghurt culture. The sugar present in the milk is fermented with the help of these bacteria produces lactic acid which is the chemical present in the yoghurt. The bacteria that helps in the production of yoghurt are Lactobacillus acidophilus. These organisms produce lactic acid. It is known as probiotic, since the live bacteria present in these substances, helps in maintaining the gut flora. It helps in keeping the appropriate conditions of the gut and aids in the proper process of digestion. It also consists of various essential compounds such as vitamin B and various other elements such as sodium, calcium, and magnesium. A prolonged time period of not taking materials such as yoghurt, in some individuals may cause an alteration in gut flora and may cause stomach problems such as diarrhoea and later, malabsorption. Therefore, consumption of yoghurt is essential in keeping the gut healthy, due to the bacteria present in it producing lactic acid.

Note: Live microorganisms like bacteria which provide health benefits are known as probiotics. During the consumption of certain antibiotics for a long period, it results in the loss of these bacteria, thereby leading to diarrhoea, therefore it is advised to take vitamin B supplements along with antibiotics during prolonged usage.
