Omega-3 Fatty Acids & Human Health
Chronic diseases like cancer, cardiovascular disease, type 2 diabetes, degenerative diseases, and others often lead to poor quality of life and high health care costs. Adequate amounts of omega-3 fatty acids—found in plant, algal, fungal, and fish oils—as part of a nutritious diet could help prevent or treat these diseases and reduce their economic impacts. However, the different forms of omega-3 fatty acids have distinct effects on human health, and some health benefits—and the recommended daily intake to achieve these benefits—are controversial. Current recommendations made by medical professionals and public health authorities are not always consistent or up-to-date, leading many consumers to be confused about how much or what kinds of omega-3 fatty acids to include in their diets.
