8. Avocado

Avocados are rich in healthy fats, mainly oleic acid, which helps fight inflammation naturally. They also contain essential vitamins like E and C, which protect joint tissues from wear and tear. Adding avocados to salads, sandwiches, or smoothies not only supports heart health but also keeps your joints lubricated and pain-free. Regular intake can help cushion your knees and reduce swelling, promoting long-term joint flexibility.
