A good immune system is able to ward off common infections easily. To make sure we have a healthy immune system, it is important to have a balanced diet, good rest and frequent exercise. While all the vitamins and minerals are important for our body, new research has found that vitamin D and omega-3 supplements are able to reduce autoimmune disease risk. At the American College of Rheumatology’s ACR Convergence 2021, researchers have presented the results of the study which presented the importance of vitamin D, omega-3 and or both of them, in preventing autoimmune diseases. Human body produces vitamin D when exposed to sunlight, which improves teeth and bone density. Inflammatory bowel diseases, multiple sclerosis and type-2 diabetes are more prevalent at northern latitudes, where the exposure of sunlight is less. Another study has also pointed out that people with increased intake of fatty fish have lower rheumatoid arthritis risk. In the trial, run on men and women with an average age of 67, showed an improvement in the reduction of risk of developing autoimmune diseases by 25-30%. The research also found out that the best results were shown by vitamin D3 supplementation. Due to increased office hours, and less time outdoors more and more people are deficient in vitamin D. A brief exposure to sunlight (preferably morning) everyday, or a weekly supplementation of vitamin D, helps in reliving with the deficiency. Omega-3 supplements or foods such as flax seeds, chia seeds, walnuts soya bean oils are also naturally rich in omega-3. If you eat fish, fatty fish such as salmon, mackerel, sardines as well as oysters, shrimps are an excellent source of Omega-3.
