The explanation is that when our brain detects sugar, it will tell your body that you want more and more such foods, plus not to mention that you will soon be hungry again. Also, this is a marketing secret shared by most fast foods to make people like their food and buy a lot, because salt and sugar are the perfect taste combo.
According to a well-known pizza chain waitress, “we put sugar in our kids’ meals so kids will like them more. Seriously. We even put extra sugar in the dough for the kids’ pizzas.”
So, the next time when you want to take your kids with you when eating out, try to give them a salad instead.
