I know, we´re so used to fast food, artificial flavorings and mostly, tag products are incomprehensible! Just follow these fours steps if you want to really care about what you put on your body (Hippocrates said already that, "let food be your medicine", and not the other way):
*Care for the Portugal flag. Because in it, there´s red and green...so in your dish! Go buy fresh, natural groceries and make them the half of your dish!
*Eat consciously. Taste food. Think food. Feel the food. That would make your bites get slower. Yes, I know it´s difficult, but hey, why not try?
*Do something physical. Just walk 10-15 minutes after each food, around the hood, around the house. That´ll pump your digestion!
*Drink water. I know it´s difficult to change habits, but believe me, if you get a big bottle of water always with you, and you have it handy, you´ll just drink water all day long!
