SUBANG JAYA, Malaysia, Feb. 2 (UPI) -- If you've ever had low-sodium soup out of a can, you can understand why scientists might be looking for a more flavorful way to reduce sodium levels.
Salt, of course, is the world's preeminent flavor enhancer. But too much sodium can lead to high blood pressure.
New research suggests fish sauce as a better low-sodium flavor booster.
Fish is a common condiment and ingredient used in Southeast Asian cooking made by fermenting sea salt and long-jawed black anchovies for several months. The resulting liquid is prized for its pungent umami flavor.
Researchers from Taylor's University in Malaysia used Vietnamese fish sauce in a number of sauce preparations common in restaurants and on grocery aisle shelves around the world -- chicken broth, tomato sauce and coconut curry. They found the fish sauce allowed chefs to reduce sodium levels without sacrificing flavor.
Taste testers confirmed that curry, broth and tomato sauce made using fish sauce as a partial salt substitute were more flavorful than low-sodium versions.
"These results may aid chefs and food manufacturers in creating foods lower in sodium content to better meet the needs and expectations of consumers, healthcare providers, governmental organizations, and consumer advocacy groups without compromising taste," researchers wrote.
"Consequently, using fish sauce as a partial replacement for salt in food preparations may be a delicious and creative alternative for many low sodium diets."
