Spicy foods may curb salt cravings, according to a recent Chinese study. It seems that two of our five tastes, salty and spicy, might have more to do with each other that we previously thought. Just this week, a study from the Third Military Medical University in Chongqing, China, drew a link between the two flavors. After analyzing the diets of 606 Chinese adults, researchers concluded those with high tolerances—and appetites—for spice tended to veer away from saltier foods and, in turn, had lower blood pressures.
This inverse relationship might be due to the presence of capsaicin, the chemical that gives chili peppers their kick. According to Zhiming Zhu, M.D., the study’s senior author, capsaicin “enhanced the perception of food being salty.” Thus, people who ate spicy foods more often developed a sensitivity to salt.
Researchers also looked at brain scans of regions that detect taste. The two sections of the brain involved in tasting salt—the insula and orbitofrontal cortex—overlap with the areas of the brain that register spice.
The connections between the two appear more than evident, but is eating more spicy food the key to heart health? I’m not sure. Personally, my spice tolerance is aggressively low, so this study doesn’t bode well particularly for me.
