Sweet Tooth or Salt Tooth?

According to an article written for Live Science, some people may carry a gene that instead of a sweet tooth gives them a Salt tooth. During tests performed it was found that a gene called TAS2R48 had a higher taste for salt and was more likely to make someone consume more salt daily. Those who did not have this gene were less likely to over consume sodium daily leading to a lower risk of heart disease. A theory along with the research is that TAS2R48 enhances bitterness; explaining why people expressing this gene seem to avoid green leafy foods. This leads people to lean towards salty less bitter foods increasing sodium intake and increasing risk of heart attack.  The hope of researchers at the University of Kentucky college of Nursing is to identify which gene variant people have and hopefully be able to help them make better food choices seriously for them.


I think this research gives an amazing stride to the fight of obesity in America. With this research, people can find out why they crave some foods over other foods. Hopefully, with this knowledge people can become more aware if they are prone to a higher consumption of salty food and be more aware of diet that would be healthier for them.  


  1. I think this is a great start into the study of improving the health of all humans. The relation of sugar to obesity is scary. This research can provide more information for people who are concerned with their health allowing them to prepare meals and other ways to help with their cravings.

  2. definitely interesting. I'm a sweet tooth myself and often wonder about my health because of it. hopefully this knowledge will help us combat childhood obesity and other diseases.

  3. This is very interesting, I didn't know that there was a gene that made us this way, I thought it was just a preference really. I don't have a sweet tooth or a salty tooth, but multiple people in my family put mountains of salt onto everything they intake. I'll have to let them know it is a gene making them that way.
