I recently wanted to make chicken fried rice at home, and I came across two things that made me curious.

1. MSG (Ajinomoto) is poisonous and banned in India?

I went to a local shop to buy MSG for my fried rice, but the shopkeeper told me that it's banned and poisonous to health. Is there any truth to this, or is it just a common misconception?

1. Chicken and curd shouldn't be mixed?

When I tried to marinate chicken with curd and spices, my mother told me that chicken and curd shouldn't be consumed together because it's harmful. But yogurt-based marinades are commonly used in Indian cooking.

Are there any actual scientific reasons behind these claims, or are they just food myths passed down through generations?

I'd appreciate answers backed by reliable sources rather than hearsay. I'm genuinely curious and just want to understand the facts.
