What is the nutritional value of oysters?

Oysters provide the highest concentration of zinc of any food, more than 33 mg per serving, and are also an exceptionally good source of vitamin B12 and the trace minerals copper, iron, and selenium. A 31/2-oz (100 g) serving contains approximately 137 calories, 14 g of protein, 105 mg of cholesterol, and 4.9 g of fat, with 536 mg of EPA and 584 mg of DHA, both of which are omega-3 fatty acids.

One of the storied historical uses of oysters is as an aphrodisiac. This effect, if in fact true, could be due to oysters' high zinc content. Zinc is essential for the proper action of testosterone and is a key nutrient in sperm production.
