At least once in your lifetime you’ve heard someone say that combining fish with milk is harmful and you should avoid it.

 

I’m pretty sure most of us heard it from our grandmothers.

 

To give the older generations some credit, I do admit that some of the sayings or the traditions we hear about happens to be eventually correct and real after some research and studies are done.

 

So is this one a myth or a real thing?

 

Let’s dive into science now.

 

Scientifically the only reason to avoid this kind of combination if you’re allergic to either of the products. No study has proven that this combination do side effects in the humans.

 

When searching for this correlation, you will find a lot of websites talking about the topic, but you will find no valid studies discussing this issue.

 

Most of the websites talk about the alternative medicine called Ayurveda, a comprehensive, natural health care system that originated in the ancient Vedic times of India (1).

 

Another theory I have in mind is that this saying was created across generations since our ancestors did not know how to cook fish and and de-contaminate milk. They ended up having undercooked or contaminated fish and milk.

 

It’s enough for a person to eat just one contaminated product and get hospitalized, so what do you think if a person ate spoiled fish and milk. I can imagine that this was a crisis back then when someone got sick and there were no medications except for some herbal products.

 

In conclusion, as there is no proof about the opposite, we can say that this combination is not toxic and for sure it will not kill you. It depends on your preference and if you like the products together. It’s preferable to avoid it if you have any known allergy to any of the products.
