Omega-3 fatty acids are considered a vital part of a person's overall well-being, including their brain health and heart health. Yet many people are still relatively unfamiliar with the benefits of these key nutrients.

Health authorities have been advising people for years to consume more omega-3s in order to avoid potential health complications. In fact, the American Heart Association says that people should eat at least two servings of oily fish – one of the best sources – per week in order to ensure they are getting enough.

Despite this, many Americans continue to eat unhealthy diets that have much higher levels of less healthy fats, while ignoring the importance of omega-3s.

In order to counteract this situation, individuals should make concerted efforts to get more omega-3s into their regular diet. Eating more fish is a great place to start. Walnuts are also an excellent source of the nutrients.

However, those who have consumed few omega-3-rich foods for many years may need more dietary help. These individuals may benefit from krill oil supplements, which are excellent sources of the critical nutrients.
