A VIRILE BOOST?
We’re not kidding when we say oysters are literally bursting with testosterone-boosting zinc – the shellfish contains up to 45mg of zinc per 100g serving, compared to 1.6mg for prawns and 2.1mg for mussels, says Alvin Wong, a dietitian at Changi General Hospital.
However, Wong stresses that zinc is useful only if the individual is deficient in it. “Although a lack of zinc can lower testosterone levels, over-supplementation will not increase testosterone levels if there is no deficiency,” he says. Sorry to burst that bubble, Romeo.
SLURP IT UP
Oysters shouldn’t be made famous (or infamous) only for their performance-boosting ability: They’re also high in protein as well as vitamins A, B1, B2, B3, C and D, says Rehana Wahid, a clinical dietitian at Gleneagles Hospital. In addition, she notes that four to five medium-sized oysters provide our recommended daily allowances of iron, copper, iodine, magnesium, calcium, manganese, phosphorus and, of course, zinc.
Oysters are also relatively lower in calories compared to other kinds of seafood, adds Wong. They typically contain around 60 calories per 100g. Their cholesterol content is also comparable to other kinds of molluscs, such as mussels and scallops. What’s more, their fat content is generally lower than that of meat, so you’ve got one healthy little bugger right there.
SHUCK AND SERVE
When you’re shopping around for fresh oysters, make sure you only get those that are still alive. A simple test: Tap their shells and they should clamp shut tightly, says Rehana.
If you need to store them, keep them in an open container and cover them with a damp cloth – do not freeze them because they will die, and well, taste bad. Squeeze over some lemon juice, because it can neutralise odours, thanks to its acidity and anti-microbial effect, says Wong.
