Most of them involve animal products, so eating vegan would help. The first two would be more difficult to avoid. I think the first one can be avoided by buying organic corn. Avoiding rice fertilized with arsenic manure would be more difficult. You could try buying rice at a farmer's market and asking the seller what he fertilizes with. FWIW, I've been trying to eat vegan for a few months now and it's surprisingly difficult at first. A surprising number of the weird ingredients in everything are derived from eggs and dairy. I was vegetarian before, and I still had to make some big changes to my diet. I like that it's made me think about what I'm eating, though.
