Growing up, you may remember learning about the four tastes that our tongues can detect: sweet, sour, bitter, and salty. But it’s now generally recognized that there is a fifth taste, a taste that’s prevalent in such foods as mushrooms, parmesan cheese, miso, tomatoes, and meat—“umami.” And this umami taste, a recent study published in The American Journal of Clinical Nutrition has found, can actually have an effect on our appetite.

Umami was first recognized in 1908 by a Tokyo researcher, Dr. Kikunae Ikeda, who postulated that there exists in many foods a savory, meaty taste that does not really fit into the categorizations of sweet, sour, bitter, or salty. He found that ground zero of this flavor is a compound called glutamate, or glutamic acid, which occurs naturally in the umami-rich foods. His work went mainstream only in the 1980s, and is now lovingly paid homage to by chefs worldwide as well as by the wildly popular burger chain known as Umami Burger (the burgers contain such toppings as truffle cheese, shiitake mushrooms, and roasted tomatoes).

Interestingly, two University of Sussex researchers found that when given umami-rich soup, their study participants initially felt an increase in their appetite as they ate, but eventually experienced greater satiety after the meal compared to the control group. This increased satiety, of course, can lead to eating less later in the day. Helpful if you’re looking to lose weight!

Given that umami flavors are generally delicious, why not seek them out then? Other foods that are considered umami-rich are seaweed, green tea, eggs, shellfish, soybeans, asparagus, and carrots.
