How Sensitive to Sweet Are You? New Taste Study Says Your Ability to Decipher ‘Sweet’ Relies Heavily on Two Letters in Your Genetic Code

If you’re someone who likes to load up on sugar during your mid-morning coffee, 3:00 p.m. work break, and late-night snack, your genes might be trying to tell you something. You may be less sensitive to the taste of sweet than other people. New research published in Current Biology has found that our ability to detect sweetness not only depends on the taste receptors occupying our taste buds, but it also has a lot to do with two small bits of DNA hiding in our genetic code that regulate sweet taste receptor levels. This research was funded and conducted by the NIDCD along with researchers from Givaudan Flavors Corporation, Cincinnati, and the University of Virginia, Charlottesville. Read the announcement on the NIDCD Web site, or read the abstract on PubMed.gov.
