What is curd?

Curd, or dahi, is produced by bacterial fermentation of boiled milk. The bacteria used to make dahi are known as ‘dahi cultures’. The quality of dahi depends on the culture used as well as the initial quality of milk and other ingredients added. In other words, curd is milk that has been acted upon by a particular kind of healthy bacteria. It improves the balance of healthy bacteria in the gut.

What is yoghurt?

Yoghurt is similar to curd but is made using a different strain of bacteria called Lactobacillus bulgaricus and Streptococcus thermophilus. Other strains of lactic acid bacteria (LAB) may also be added in addition to these in the yoghurt.

What are probiotics?

Probiotics are ‘live microorganisms which when administered in adequate amounts confer a health benefit on the host.’ Lactic acid bacteria and bifido bacteria are the most common types of microbes used as probiotics; certain yeasts and bacilli may also be used. Probiotics are commonly consumed as part of fermented foods with specially added active live cultures, such as in dahi or as dietary supplements.
