Whenever we want to go out and have something outside as we feel bored of eating the same food, you'll feel that our favorite food or any food that matters has the same common ingredient. That is "Maida".
Maida is a refined wheat flour, which is used for bakery items, Parotta, pizzas, burgers, buns and almost every snacks has maida in it.
In those days before 1990's, people used to have maida, and it doesn't have any side effects. My mom told me that she used to have those maida food products that doesn't have food adulteration but since her grandparents warned her not to eat it, she stopped eating it.
Even one of my school teachers told me that, having two parotta take 6 months to digest in your stomach.
But what is the situation right now? We still eat those foods, including myself. I am aware of what are the ingredients which is present in that food, but for my happiness, of eating that food, knowing that It will have side effects.
In the end, be aware of what you are eating and have control of eating it regularly instead have it occasionally or rarely. But before advising others, I should follow the rules.
