Organic is much higher quality than commercial, and contains more nutrition. By no means totally do away with acid fruits, as they can be very beneficial and nutritious. Just keep in mind that you can have problems with your teeth if you eat too many of them, or too often. There are many varieties of leafy greens and stalks which are mineral-rich and are a good source of many other nutrients. It can be a good idea to eat these green vegetables at the same time as sweet fruits.
Organic greens are good, but wild greens are the best.
