Chia seeds are the richest plant-based source of alpha-linolenic acid (ALA), a type of omega-3 fatty acid. Omega-3 fatty acids are known for their strong anti-inflammatory properties, and a number of studies have found that an increased intake of omega-3 fats can reduce joint pain and inflammation, as well as joint stiffness in people with rheumatoid arthritis.
I have been taking chia seeds since 2015 and I believe it keeps me healthy and helps me to go into remission too. Do Google the good and bad of its if you intend to try it. Also do check on how to eat it to avoid any side effects.
