The fabled Patagonia region of Argentina beckons visitors seeking adventure and the mystique of a place that is now emblazoned on the logo of a brand-name clothing outfitter.

But for Jane Teas of Columbia, South Carolina, a December 2009 trip to Argentina was a chance to learn more about seaweed harvesting.

Guests at restaurants in Argentina's Buenos Aires province must say good-bye to the salt shaker.

In an effort to combat hypertension, which affects some 3.7 million residents in the province – nearly a quarter of the population, the health department reached an agreement with the hotel and restaurant federation to remove salt shakers from the tables at their eateries.

"On average, each Argentinian consumes 13 grams of salt daily, while according to the World Health Organization, you should consume less than five," Health Minister Alejandro Collia said when he announced the change last month.

The measure is not as extreme as it sounds. Salt will be available by request, but only after the patrons have tasted their food.
