Buttermilk (“छाछ” in Hindi) is enjoyed in many homes across India. If you’ve grown up in an environment that believes in some common myths regarding food, there’s a good chance that you are aware of the phrase that restricts you from mixing fish and dairy in your diet. Some common phrases used as warnings are “Don’t consume milk after eating fish” and “Do not drink dairy after eating fish.”

So do these old-fashioned rules regarding food really have a valid meaning to them, or are they just continued to be passed down from generation to generation without any valid evidence proving they are harmful? This will be discussed in more detail in the following blog provided by Dietitian Shubhra, and let us understand what happens in our bodies when we mix and consume fish and buttermilk or any other dairy product.
Centuries of disagreement on the combination of fish and dairy continue today, particularly in the world of Ayurveda, where foods are classified by how hot or cold they are. Fish has been classified as warming or heating “virya”, while dairy products such as milk and buttermilk have a cooling “virya.”
When combining foods with opposite “virya”, there is said to be an excess of digestive fire (Agni) resulting from this combination of foods disrupting the body’s internal balance.
