There have been no new articles in over a week during my absence; which is a shocker, because it makes me surprised that no one here came out with any decent articles at all. But that's about to change because I have a wonderful article, and there will be another new article on Monday.
I am sure you have all heard of a sweet tooth, it gives you that craving and taste for sweet delicacies. A recent study conducted has found that meat-eating mammals do not have a sweet-tooth. According to the study, animals that lack sugar in their diet may lose the ability to taste it. When Gary Beauchamp and his co-workers from the Monell Chemical Senses Center in Philadelphia began looking at DNA samples, they were not sure what they were looking for in the animals' receptor genes.
In an interview with the team they said, "At the time, the feeling was that the cat was a very unusual anomaly among mammals in that it didn't respond to sweets. But we wondered if the cat represented something that had happened many times." The majority of the DNA samples were provided by the San Diego Zoo, and it was found that sea lions and hyenas were among the most affected by the non-functioning Tas1r2 receptor. This study demonstrated the effect on an animal based on its diet.
This shows that it is possible for any mammal to lose some sort of taste over a very long period of time. Although this generally means that humans have a slight chance of loosing the taste of sugar over time, this would be highly unlikely because there is a trace of sugar in almost everything we eat. At the time I first learned this I was shocked because of the joyful taste of sugar we experience is not felt by the carnivores in the animal kingdom.
