Thanks for your concern regarding my health issues. I am also trying to stop consuming unhealthy foods currently and reduce my weight gain. But it is difficult for me to cook on a regular basis due to my tight schedule. Yeah, the food in the Indian subcontinent can be life-threatening if you are not careful before buying street food as a foreigner. But native people are okay with these foods as a habit, most of the time. Halal foods are same like normal foods, only requirement for meat as we can not eat those animals meat which are sacrificed for other gods except Allah as in Hinduism. But all meats are halal from the Christian and Jewish shop, as our God is the same Allah. If you don't know, you can read some articles, and as far as I remember, I have told you on this point earlier. Halal foods are not different; all fish and vegetables are halal from anywhere. Only animals should be sacrifice in the name of Allah for making it Halal, and some other meat like pork, carnivorous animals, and blood are not halal.
