In the United States, a fascinating correlation exists between the affluence of a state and the prevalence of gluten-free searches online. This connection suggests that higher income levels may influence dietary choices, particularly the adoption of gluten-free products. Groundbreaking research has delved into the factors contributing to this trend, revealing that wealth, urbanization, and access to healthcare and education play significant roles in the rise of gluten-free living.
An original analysis by Gluten Free Pages highlighted a global pattern where countries with higher GDP per capita showed increased maturity and growth in the gluten-free market. This relationship appeared logarithmic, with a strong correlation for most countries. The hypothesis then extended to regions within countries, including states and cities.
Further investigation into the top ten wealthiest states in America, as measured by average income, revealed a pronounced interest in gluten-free products. However, the poorest states either lacked data or showed sporadic interest. The top ten average income states with notable gluten-free demand growth rates are:
Google's data on annual growth rates for gluten-free searches as of late December 2009 identified several states with significant increases. Notably, states like Colorado, Oregon, New Hampshire, Washington, Minnesota, Massachusetts, and Connecticut were among those with the highest gluten-free search rates, some of which also rank among the wealthiest.
However, not all wealthy states showed high gluten-free demand, suggesting that wealth distribution and demographic factors, such as ethnicity and genetic predisposition to celiac disease, also influence this trend. For instance, Caucasians have a higher rate of celiac disease, which could affect the level of gluten-free searches in a community.
The growth of gluten-free searches within states is often driven by specific cities. Urban areas with higher wealth and education levels contribute significantly to the state's overall interest in gluten-free products. For example, Littleton and Denver in Colorado, as well as Portland in Oregon, are among the top gluten-free growth cities in the U.S.
While wealth and education are precursors to effective celiac disease diagnosis, high growth in gluten-free searches does not always equate to market maturity. With celiac diagnosis rates in the U.S. below 10%, many states are still in the early stages of adopting gluten-free diets. The highest growth states, based on a two-year period, are likely the most mature in terms of gluten-free market development.
Despite weekly fluctuations in Google's growth rate data, the correlation between a state's wealth and its interest in gluten-free living persists. States with a few high-ranking cities or many moderately ranking cities in gluten-free searches tend to show overall high growth rates. With celiac diagnosis rates around 5% and a surge in online gluten-free searches, this report identifies the current hotspots for gluten-free interest across America.

The Evolutionary Journey of Domestic Dogs from Ancient Wolves
The domestication of dogs from wolves is a fascinating tale of evolution and human influence, leading to the diverse array of canine companions we cherish today. While the story of how wolves became dogs is widely known, the specifics of this transformation are often overlooked or misunderstood. A groundbreaking study in 2009 provided compelling evidence, using mitochondrial DNA analysis, to pinpoint the domestic dog's origins to a region in China between 10,000 to 16,000 years ago. This research not only sheds light on the domestic dog's genesis but also on the intricate relationship between humans and their four-legged friends.
