A nutrition researcher says human diet needs more shellfish because it has some of the most important essential nutrients humans need.

Professor Baukje de Roos, deputy director of the Rowett Institute at the University of Aberdeen in Scotland, discussed the major health benefits of seafood and highlighted the contribution of shellfish to a healthy diet at the conference of the Association of Scottish Shellfish Growers in Oban, Scotland.

Mussels, oysters, and king scallop roe contain Omega-3 levels between 1.1 and 2.4 grams per 100 grams of flesh, similar to oily fish such as mackerel, herring, and salmon, de Roos was reported as saying by Seafoodsource. Omega-3 fatty acids help to protect against stroke and lower the risk of mortality from coronary heart disease.

“Micronutrients such as selenium, iodine, and zinc are also found in abundance in shellfish and all have important functions,” de Roos said. “Oysters in particular are high in zinc and would be a good addition to the diet of anyone aware that they have a deficiency.”

Two trace elements commonly found in shellfish--cadmium and lead--were also found in increased levels in humans following increased consumption of mussels, but these were well below hazardous levels, even with three portions per week, said the report.
