Been there for 20+ years, and it is incredible for appetite they have for unhealthy food and snacks. Just like back where I come from (in the western world). When at markeds or outlets where they sell fresh food, you have to demand they not using sugar in mixed vegetables, or stir fried veggies as well. If not, they pour on the sugar and/or the MSG in most food items.
And sugar. The obsession with sugar in Thailand is crazy. Cant even get a vegetable dish without the sweet taste. I think Toothpaste is the only product still without sugar in it, in Thailand. And they are getting fatter and fatter.
