Ghee is a tradition here. Olive oil is a tradition in Europe. Soybean in china. All suitable for respective local environment. If you live in China, you should eat Soybean. But in India? Why? Food Tradition does not come up overnight from scientist’s lab like your Crosin tablet that works everywhere with same side effects 😀.
Traditions emerge from social labs, our homes, by live experiments over several generations, under the guidance of Rishi personalities (The one with sharp and blessed observation powers). Traditions exists because they have proved benefits to many. Fake traditions do not stand against the time. What is suitable here, may not work well in Canada. What is best in Canada, may not work here (For example Canola oil).
Trust and follow your local food habits passed to you by parents, and get benefited. Doubt and live in self-denial? Loss of all benefits. Pay the price.
Side note: One of the hidden benefits of respecting food traditions is reduced transport due to demand of exotic food. Think about it. You can make huge difference!
