There are two types of arthritis.

Osteoarthritis – Osteoarthritis is a degenerative condition that often occurs with age. This causes stiffness and pain in the affected joints. Being overweight can sometimes worsen symptoms due to the greater load on the joints.

Rheumatoid arthritis – Rheumatoid arthritis is an inflammatory condition which involves multiple joints. The joints often swell and cause pain. Sometimes the sufferer (typically adult women) will go through periods of remission.

Nutrition to Relieve Arthritis Symptoms

Unfortunately there is conflicting advice regarding diet for arthritis. Despite some clinical trials taking place, many results are considered to be a placebo affect. However there are some guidelines that may help.

Oily fish such as cod liver oil supplements, tuna, salmon, and sardines.
Vitamin C - found in many foods such as kiwifruit, peaches, oranges.
Vitamin E - Unsalted nuts
Turmeric and ginger - anti-inflammatory foods (use in curries, soups, or stews).
Some report that a vegetarian or vegan diet has helped.

Foods That May Aggravate

Some report that vegetables from the solanum (or nightshade) family cause problems - potatoes, capsicums, eggplant, and tomatoes.
Foods high in saturated fat such as full-fat dairy, fatty meat, baked foods.
Dairy products

Finding What Helps You

The only method to find out if something is aggravating your arthritis is to constantly monitor your diet. Do this by keeping a record of what you have eaten, and what pain you experience. If you begin to notice any patterns (such as joint pain the day after eating a certain food), you will need to try and isolate the cause.

Take the food out of your diet for a week, and see if you experience the same arthritic symptoms. In order to make any correlation, you will need to do his 3 times.
