New Delhi, Nov 3 (ANI): Omega-3 fatty acids, which are normally found in fish, if taken in excess could have unintended health consequences in certain situations, a new study has suggested. Omega-3 fatty acids have anti-inflammatory properties, which is one of the reasons they can be beneficial to heart health and inflammatory issues. However, the researchers said excess amounts of omega-3 fatty acids can alter immune function sometimes in ways that may lead to a dysfunctional immune response to a viral or bacterial infection.
