5. Salt

Excessive consumption of salt (or sodium) can lead to a multitude of health issues caused due to water retention and high blood pressure, including joint pain. Your body needs the right balance of fluid to lubricate and cushion the joints, but too much of it can cause bloating and inflammation. This will cause your joints to swell and put you in a lot of pain.

Since modern diets contain a lot of salt, it’s important to stay away from things like junk and fried foods. If you have arthritis and are already taking a corticosteroid, your doctor will recommend you reduce or even skip the salt completely, as the medication itself is notorious for causing salt retention.
