Changing a diet when having rheumatoid arthritis is a good idea. Eating junk food, a lot of meat and drinking alcohol will not help you. Smoking is bad for your health, as well as bad sleeping habits. If you found out recently that you suffer from rheumatoid arthritis, then you should react quickly and get yourself a good RA-friendly diet. Consult with your doctor and a nutritionist if you are not sure about certain ingredients, but eating fruits and veggies and drinking pure, fresh water can only affect your body in a positive way.
For lunch, you should not eat only meat, but also cereals, nuts and veggies. For example, you can make a pumpkin soup and spaghetti with broccoli. Add a salad which you have made with many ingredients like lettuce, onion, olive oil and lemon juice. That will be excellent and delicious lunch that will give you important nutrients. For a dinner, you can make eggs with whole wheat bread and tomatoes. Try to reduce the amount of dairy products.
