Tag: Salty vs sweet

According to research, humans are biologically hardwired to crave salt because it was a scarce and necessary nutrient for our survival in the wild. Today, if you find yourself asking, 'Why do I crave salty instead of sweet?', the reasons are more complex and often tied to underlying physiological and psychological factors.

According to research published in the journal *Twin Research and Human Genetics*, genetic factors are responsible for about 30% of the variation in sweet taste perception among people. This science helps explain the meaning of "do not have a sweet tooth," an idiom referring to a lack of fondness for sugary foods, which is rooted in a fascinating mix of biology and personal history.
