Rarely do I eat anything that is not organic, but especially not foods from the dirty dozen. If nothing else is available and I needed it then I would. The most common non-organic food's I buy are blackberries and bananas, because we love them and they are not available organic in our area. Our meat is not certified organic, but is from a farmer who we know and trust and have seen the animals on the green pasture and he believes just as we do that medications, hormones, etc are bad so he does not feed them these things.
We follow a traditional foods diet, lots of meat, some organ meats and fermented veggies, lots of veggies period, whole foods, no processed foods (once in awhile we will buy something organic that is processed like organic mac and cheese if I am sick and need a quick meal for the family), we try to stick to gluten free, very little added sugar, soaked grains like oatmeal, lots of eggs (from our own chickens). We have a big garden in the summer and this summer I am planning on fermenting lots of our veggies. We try to buy local whenever possible, to eliminate the environmental impact of manufacturing, shipping, packaging, and so we know how our food was raised/grown. For an adult I guess I would say yes its ok to eat non-organic things sometimes but for a young child who is developiing I would say no for the most part. I will never eat a doughnut for example, not only because of the disgusting unhealthy ingredients, but also because of the environmental impact of shipping, manufacturing, packaging and the environmental impact of the farming techniques used to grow the wheat, soy, corn, etc that is in it. Yuck!
If it is a whole food and its at someone else's house and they offer it to us, for example an orange, then I will say yes, but if they offered us a burger made from Walmart hamburger its a NO, a candy bar would be a NO, Wonderbread is no, etc.
