Teresa, the worst oils for me personally are the polyunsaturated vegetable oils, such as corn, safflower, sesame, canola, etc. When I eat them, they increase my tinnitus and disequilibrium. I tolerate coconut oil and fish oils much better. Salmon and trout actually make me feel better, reducing my symptoms of dizzyness and tinnitus. I tolerate olive oil -- which is mono-unsaturated -- fairly well, but not as well as the coconut oil and especially the fish oil. But the most important thing I've noticed is that eating too much oil seems to be the biggest issue.
I'm not sure why this is, but I've got some theories. First, polyunsaturated vegetable oils are reputed to be highly unstable and become rancid very easily. When cooked, about 15% of the oil becomes transfat. The rancidity and transfat content generate free radicals in the body, which generally promote any disease condition. Also, excess dietary fat clogs the liver, which processes metabolic wastes in the body. A toxic body is one that also promotes disease conditions.
Of course, these are just theories. The most important thing is that I've noticed what foods make me feel better and which ones make me feel worse. It might not be the same for everyone. It's a personal observation that I mentioned on the chance it might be helpful to someone else as well.
Certain activities (or staying up too late at night) also make my symptoms worse. FlyersFan68 makes a good point about eyestrain from working at the computer too long without a break. That definitely makes my symptoms worse, too.
Getting a lot of sleep, not working too late/long, eating a clean and balanced diet, and exercising regularly seem to be the main keys to managing my symptoms. When I do all that, I actually feel fairly close to normal and have few limitations (like not being able to do technical rock-climbing anymore).
Hope that helps,
Tumbleweed
P.S. Please feel free to send me a PM when you have a question specifically for me. I don't read all the posts on this forum and I almost missed your question, Teresa. Best wishes.
