What is claimed is: 1. A composition, comprising an edible product and an antioxidant polymer that includes repeat units represented by one or both of Structural Formulas (I) and (II): wherein: R is —H or a substituted or unsubstituted alkyl, acyl or aryl group; Ring A is substituted with at least one tert-butyl or substituted or unsubstituted n-alkoxycarbonyl group, and optionally one or more groups selected from the group consisting of —OH, —NH, —SH, a substituted or unsubstituted alkyl or aryl group, and a substituted or unsubstituted alkoxycarbonyl group; and Ring B is substituted with at least one —H and at least one tert-butyl or substituted or unsubstituted n-alkoxycarbonyl group, and optionally one or more groups selected from the group consisting of —OH, —NH, —SH, a substituted or unsubstituted alkyl or aryl group, and a substituted or unsubstituted alkoxycarbonyl group; n is an integer equal to or greater than 2; and p is an integer equal to or greater than 0. 2. The composition of claim 1, wherein the edible product is an oil or contains an oil. 3. The composition of claim 2, wherein the oil is canola oil or corn oil. 4. The composition of claim 1, wherein the composition is margarine. 5. The composition of claim 1, wherein the antioxidant polymer includes at least one repeat unit selected from the group consisting of: 6. The composition of claim 2, wherein the oil is selected from the group consisting of cottonseed oil, linseed oil, olive oil, palm oil, corn oil, peanut oil, soybean oil, castor oil, coconut oil, safflower oil, sunflower oil, canola oil and sesame oil. 7. The composition of claim 6, wherein the oil is soybean oil. 8. The composition of claim 1, wherein the edible product is vegetable shortening. 9. The composition of claim 1, wherein the edible product is selected from the group consisting of meat products, dairy products and cereals. 10. The composition of claim 1, wherein the antioxidant polymer is a homopolymer. 11. The composition of claim 1, wherein the antioxidant polymer is a copolymer. 12. The composition of claim 11, wherein the copolymer further comprises one or more synthetic or natural antioxidants as repeat units.
