Including omega-3-rich foods in meals is vital, as unlike other types of fats, the human body cannot make them. Omega-3 fatty acids are essential nutrients that build cell membranes and help reduce inflammation. Most fatty fish, nuts, and seeds are excellent sources of this nutrient. However, those who don’t eat fish or are allergic to nuts can opt for fish oil supplements, which offer many health benefits, as mentioned below: 1. Lower inflammation Low inflammation levels are necessary to avoid the risk of diabetes and numerous other health concerns. People who are at a higher risk of diabetes have higher levels of inflammation in the body and, thereby, elevated cortisol levels and decreased brain function. Having fish oil supplements improves cognitive well-being and reduces inflammation. It can also improve the chances of avoiding conditions like cancer, arthritis, brain disorders, and heart diseases. Optimum levels of omega-3 fatty acids in the body help reduce the risk of heart attacks by up to 9%. It also helps reduce triglyceride levels, which can help with plaque buildup in the heart vessels. 2. Improve cognition Those who take fish oil show improved mental capability. Omega-3 fatty acids are known to benefit brain and heart health.
