A varied diet generally provides the amino acids required for tissue maintenance.
### Eat Plenty of Fruits and Vegetables
Oranges and strawberries are useful, but they are not the only sources of vitamin C.
Other excellent options include:
* Kiwi
* Bell peppers
* Broccoli
* Citrus fruits
* Tomatoes
* Brussels sprouts
Variety provides a broader range of nutrients than relying heavily on one or two foods.
## Is “Inflammation” Always the Cause of Joint Pain?
No.
Joint pain can result from:
* Osteoarthritis
* Rheumatoid arthritis
* Injury
* Tendon problems
* Bursitis
* Gout
* Infection
* Referred pain from another area
That is why describing every joint symptom as “inflammation” can be misleading.
Persistent or unexplained pain deserves proper evaluation.
## When Should Knee Pain Be Checked?

* Difficulty bearing weight
* Reduced range of motion
