No Sign That Ethnic Groups Genes Cause Diabetes

“A study by U.S. and Australian researchers is helping dispel the 40-year-old “thrifty genotype theory,” which purports that certain minority groups are genetically prone to diabetes.

The study, co-authored by UC Irvine anthropologist Michael Montoya, along with an epidemiologist and population geneticist, analyzed existing genetic studies published across a variety of disciplines. The team found no evidence to support the widely held thrifty genotype theory, which suggests that cycles of feast and famine early in human history created a gene that helps the body use scarce nutrients – a gene that leads to obesity and diabetes in comfortable, sedentary modern lifestyles.”
