I'm not an expert on this, but in my experience, staying away from the major allergens (including cow milk, soy, corn, wheat, eggs, etc) is a good first step, along with avoiding processed foods. When I go to the grocery store, and if I'm buying something packaged, I try to make sure the list of ingredients is very small and that i can identify each of the ingredients. If I can't, it's too processed for me
Some people think meat is inflammatory, and goodness knows, our meat is fed with hormones anyway, and there was a recent study showing how any number of servings of meat a week correlated with increased risk of death, so it's probably a good idea to limit that too.
I am a firm believer that food is medicine, and that by eating well, we can do a lot to help our health. In my personal experience, a healthy diet is much more important than exercise, so really focus on it all that you can.
I'd also recommend you see an ophthalmologist about your eyes. It's probably nothing, but best to check it out. Good luck!
