Healthy eating is at its lowest level in 2016, with 63.2% of U.S. adults reporting eating healthy all day the previous day, down from a high of 67.7% in 2010, representing a decline of over 10 million American adults eating healthy on any given day since that year. 
 
 This report also explores the relationship between healthy eating and various chronic diseases - obesity, diabetes, heart disease, depression and stress - finding those who ate healthy all day the previous day had lower disease burden across conditions than those who did not. This research suggests that an emphasis on healthy eating and sensible food policies could have a positive impact on lowering disease burden within communities nationwide. 

 Few habits affect overall well-being more than a healthy diet, and the probability of eating well largely depends on one’s place of residence. The “2016 Community Rankings for Healthy Eating” report examines the wide range of eating habits across the nation. 
 
 According to the May 3rd report, published by Gallup-Sharecare, a partnership between the polling organization and the digital health company, 10 communities in California, four in Florida, and two each in Texas and Arizona have the healthiest eating habits in the nation. The Naples-Immokalee-Marco Island, Florida metropolitan area leads the nation, with more than 75% of residents reporting healthy eating. 
 
 24/7 Wall St. reviewed the 25 metro areas with the highest shares of residents reporting such healthy eating habits. We also examined several other factors research has shown to influence diet, as well as associated health outcomes.

 In its poll, Gallup asked metro area residents, “Did you eat healthy all day yesterday?” Dan Witters, research director of the Gallup-Sharecare Well-being Index, in an interview with 24/7 Wall St. noted that while health literacy can influence how people respond to this question, “most people have a pretty good idea of what it means to eat healthy or not.” 
 
 To a large extent, in other words, healthy eating decisions are conscious choices. Several key well-being metrics, including the presence of someone who encourages you to be healthy, and notably stress levels, support healthy diets. 
 
 Of the 25 cities where the largest share of residents eat healthy diets, only in nine did residents report above-average daily stress levels. Nationwide, 40% of adults reported daily stress. 
 
 In addition to strong relationships, income levels and money management are closely related to dietary decisions. The ability to pay for high quality food is often a limiting factor for low income families. Fruits, vegetables, and fresh produce — some of the most beneficial additions to a healthy diet — also often happen to be among the higher priced items at the grocery store. 
 
 The median household income in 16 of the 25 cities with the healthiest diets is higher than the national median of $55,775 annually. 
 
 While financial constraints can contribute to poor diets, Michael Acker, director of the Blue Zones Project at Sharecare, noted that healthy eating decisions are entirely possible on low incomes. Blue Zones projects — programs that implement features of long-living communities from around the world — and other community efforts like farm-to-table programs, food policy councils, and community gardens can contribute to healthy outcomes even in low-income communities. 
 
 For Acker, while individuals generally know whether they are eating healthy or not, they do not always understand the outcomes of particular eating habits. Especially in poorer, economically disadvantaged communities. Acker explained, “The common perception is that things like diabetes and heart attack in your family are primarily genetic, and we know this is simply not true for the most part.” By focusing on educating communities on the effects of lifestyle on health, community organizers and health advocates have had success improving diets across a population. 
 
 In the areas with the healthiest diets, adverse health outcomes are considerably less common than across populations reporting poor eating habits. The probability of being obese, for example, declines substantially for people who eat healthy. Only two of the 25 cities with the healthiest diets have an obesity rate greater than 30%. Only nine have obesity rates over 25%. 
 
 These are the 25 cities with the healthiest diets.
– All the hype about California healthy living appears to be well founded—at least when it comes to mealtime. A new report by Gallup and Sharecare, a digital health firm, looked at eating habits in 189 metropolitan areas across the US with one simple question: "Did you eat healthy all day yesterday?" The survey, which also looked at other factors such as stress levels and obesity rates, puts Florida's Naples-Immokalee-Marco Island area in the No. 1 spot, but the Golden State claimed four out of the top 10 rankings. Even if your paycheck doesn't put you in a high tax bracket, a healthy diet is within reach, especially if you live in an area that features community gardens or farm-to-table programs, a Sharecare expert tells 24/7 Wall St. The top 10 metro areas, plus the percentage of adults who eat healthy all day long in each area: Naples-Immokalee-Marco Island, Fla.; 75.3% Barnstable Town, Mass.; 75.1% Santa Cruz-Watsonville, Calif.; 74.2% Salinas, Calif.; 72.9% McAllen-Edinburg-Mission, Texas; 72.4% Santa Rosa, Calif.; 72.3% Hilton Head Island-Bluffton-Beaufort, SC; 72.0% San Luis Obispo-Paso Robles-Arroyo Grande, Calif.; 72.0% Lake Havasu City-Kingman, Ariz.; 71.0% El Paso, Texas; 70.9% See how other cities rank here.
