“…Evaluating these considerations, advantages and nutritional benefits of a diet rich in fish or other seafood are particularly due to the content of high-quality protein and high concentrations of EPA and DHA in various marine species (45)(46)(47). The most appropriate fish choices for consumption, particularly with regard to the amount of O3-HUFAs, the predatory characteristics, and the concentrations of contaminants (e.g., methylmercury, polychlorinated biphenyls and dioxins), are anchovies, atlantic herring, salmon, trout, and sardines (27,(45)(46)(47)(48). For subjects who prefer a diet with safe concentrations of contaminants and would like to enjoy the benefits of O3-HUFAs, fish oil supplements or intake of foods such as walnuts or oils from flax, canola, or soybean, can be alternatively given (49,50).…”
