So after the elimination phase I've slowly added back nuts of all kinds, some seeds, eggs, rice, peppers/tomatoes occasionally, potatoes occasionally, and vary rarely do I put any type of dairy into my body. I rarely treat myself to some mexican food and so that usually has some corn or beans in it but neither of those are staples in my diet eating, so a meal like that once a month hasn't caused a flare. If I eat at a restaurant I look for something simple like a steak with a side of veggies. If there's butter on either of them I don't get too stressed about it.
I still stay away from heavily processed food, gluten, industrial cooking oils like canola/rapeseed/cotton seed/sunflower/saffleflower/rice bran oil, oats, other various grains, grapefruit(potential interaction with my meds), peanuts, refined sugar, and soy.
So yes, lots of veggies, lots of fruit, lots of meat, fish, eggs, and some nuts make up the bulk of my diet. I supplement with Type II collagen which has shown to really modulate the inflammatory response your body has to arthritis and can halt osteoarthritis and rheumatoid arthritis in it's tracks.
So arthrosis is typically another term for osteoarthritis here in the states, however most just call it osteoarthritis if that's what is meant. Arthritis is a general umbrella term used here that many types of joint inflammation falls under. Septic arthritis, OA, RA, psoriatic arthritis, reactive arthritis.....all fit under a general description of arthritis but most people have no problem using the specific term that affects them. In arthritis the damage done to the cartilage/bone almost always has a component of inflammation with it so the term can be used interchangeably to describe both.
