The average omega 3 - 6 balance score of typical US foods is about –6. This imbalance causes the average American to accumulate tissue proportions of n-3 and n-6 highly unsaturated fatty acids (HUFA) with about 77% n-6 in HUFA. This HUFA balance links to many chronic health conditions that are made worse by overabundant actions of food-based omega-6 HUFA. Americans currently spend more on treating food-based health conditions than they spend on food. Less medication is needed to treat signs and symptoms when a key dietary cause of the signs and symptoms is prevented. Informed food producers can readily prepare and market new food products with more n-3 and less n-6 nutrients to reverse the current national nutrient imbalance and help people attain and maintain a healthy HUFA balance. New functional foods and nutraceuticals will help consumers shift their financial resources from treating signs and symptoms caused by HUFA imbalance to preventing the nutrient imbalance that causes the need to treat.展开更多

It was determined recently that n-3 HUFA (es-pecially 22: 6(n-3) (DHA) and 20:5 (n-3) (EPA)) is essential for larval seafish growth. Thehigh content of DHA in seafish eggs and the low content of DHA in rotifers show that rotifersas live food cannot satisfy the n-3 HUFA requirement of larval seafish. Some scientists ob-展开更多
