Do You Eat Native?

So many people are eating foods that are not native to their own countries. The likes of Gillian McKeith tells us to be eating foods like Quinoa and Sweet Potato but these foods have to come a long way to get to thir destination. Also, if they are grown in Africa, we might be adding to the problems of food that Africa is experiencing. Africa has a problem feeding its own people let alone us too and there is also problems with water. This is one of the reasons that Lake Chad is getting smaller and smaller. What do you do in the name of healthy nutrition?
