I haven't noticed that certain foods make my joints worse or better but what I have noticed is that eating a healthy diet that includes lots of fruit and vegetables, whole grains and foods that contain complex carbs makes me feel better overall. Along with that I've found that daily excercise makes me feel better too; sometimes I'm in so much pain that I can only walk a short distance but when I feel good I do yoga and I swim laps both of which I love.
Just wanted to clarify something Robert said in his post and I quote "Try to eat EVERYTHING FRESH. As much as possible without CHEMICALS.
Because the chemicals (colors, anti-oxidants, ....) are the devils."
Robert I totally agree with this advice with one exception. Anti-oxidants are not a man-made chemical and are not bad for you. On the contrary, anti-oxidants are a naturally occuring very good for you naturally occurring chemical. Anti-oxidants are a very important cancer fighter and can be found in many foods that are very good for you, example Broccoli is very high in anti-oxidants. You want to eat as many foods that are high in anti-oxidants as you can because they do not make joints worse - in fact there is some evidence that they may have anti-inflammatory properties. I hope you don't mind me making this comment - I do not mean to offend.
Another point I'd like to make is that a diet that is completely devoid of carbohydrates is not a good diet to be on because our bodies need "sugar" to run; it is the fuel our brains need to think and our physical body needs to operate. However,not all "sugars" are created equally; those that are naturally occurring in fruits and whole grains and beans/legumrd are sources of good sugars while those from processed foods and refined sugars are not good for our bodies. Basically the difference is that the sugars found naturally in food takes longer to break down and are therefore released more slowly into a person's blood stream. This prevents spikes in a person's blood sugar as well as spikes in insulin. When a person eats processed foods and foods that are high in sugar without fiber or protein in them, the sugars are released quickly into the blood stream causing blood sugar and insulin peaks. It's like all the work of digesting the carbohydrate is done for you before you eat what ever high sugar food it is. Insulin peaks and high insulin levels found in insulin resistance can have an inflammatory effect in the body and goodness knows we don't need any help in that area! So don't get rid of all sugars, just those that are in processed foods and those often found in large amounts in foods that are processed to be low fat. If the sugar you are eating also contains fiber and protein it will be digested and released slowly so these are the sugars you want to have to feed your body's need for fuel. This would be good advice for all people not just those of us with already diagnosed inflammatory arthritis.
