Phytochemicals

They are neither vitamins nor minerals but occur naturally on plant foods.

They are not essential; the absence of them in the diet will not result in death. However, they are important to our body especially at a time when our exposure to free radicals producer has never been greater.

Many have been discovered these past few years. Tremendous studies are being done and scientific papers about them are proliferating. We have new information about them every day and it is hard to stay updated. Several hundred types of phytochemicals have already been found.

They have been proven to have powerful antioxidants.
