Nutrition plays a significant role in impacting physical function and body metabolism. Recent human studies also show the importance of n-3 PUFAs on exercise, metabolic response, and functional improvement during exercise training. Their anti-inflammatory and antioxidant properties further contribute to potential health benefits and enhanced performance, particularly in individuals engaged in physical activity. There are three types of omega-3 fatty acids: α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
ALA is primarily found in plant sources such as flaxseeds, chia seeds, walnuts, and canola oil. It is considered an essential fatty acid because our bodies cannot produce it and must obtain it from dietary sources.
EPA and DHA are commonly found in fatty fish and fish oils, such as salmon, mackerel, and sardines. These omega-3 fatty acids are readily utilized by the body. They are known for their important roles in supporting brain and cardiovascular health.
Dietary Recommendations for Omega-3 Fatty Acids and their Sources
American Heart Association (AHA) suggests that adults should consume a minimum of two servings of fatty fish per week, such as salmon, tuna, mackerel, herring, and sardines, which are rich sources of omega-3 fatty acids. Additionally, alpha-linolenic acid (ALA) food such as flaxseeds, chia seeds, and walnuts are also recommended by AHA. It is crucial to note that excessive consumption of omega-3 or omega-6 fatty acids can have adverse health effects. Health organizations typically advise a daily intake of at least 250 mg and up to 4,000 mg (but not exceeding 5,000 mg) of EPA and DHA combined.
