Building new supermarkets in food deserts likely won't help as much as nutrition education in closing healthy-eating gaps.

In the 1980s, the Reagan administration stopped enforcing a law prohibiting discriminatory pricing, giving large chains an advantage and driving smaller stores out of business, which created modern food deserts.

See how food access varies across America with these interactive maps that show grocery store proximity.

With Americans increasingly concerned about high grocery prices, experts suggest meal planning and using apps like TooGoodToGo to keep household food costs down.

The health food industry grew significantly in the early 1990s

By 1996, there were over 6,000 health food stores in the US, which generated over $9B in sales. That was still a small number compared to traditional supermarkets, but it was a 17% improvement in annual growth over the previous five years, highlighting a rapidly growing industry.

Dollar stores are often found in rural, low-income areas of the US

Shoppers in these areas are increasingly turning to dollar stores for food.

Many issues facing urban environments cannot be solved by smart technologies

Although connecting systems to the Internet of Things can provide improved efficiency in municipal systems, problems such as limited affordable housing are driven by larger socioeconomic factors. Some experts suggest that local governments should focus resources on practical solutions to these issues rather than investing in smart technologies.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States. Ethnic foods with their (supposedly) hunger-triggering spices were vilified and considered “stimulants” along the lines of caffeine and so, in their stead came prune puddings, canned-meat stews, and dairy-heavy vegetable casseroles featuring America’s first fortified foods. Read more here.

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes.

Why grocery stores play music while you shop

Grocery stores don't play music just for the good vibes. Store soundtracks have been proven to increase spending and improve customer experiences, especially if the music is upbeat. If the tunes are nostalgic for the stores' key demographics, it can help develop a store’s desired brand identity. This article from Reader's Digest details the many reasons behind this strategy.

Over the years, the USDA has changed its definitions of healthy eating

The US Department of Agriculture began offering eating advice in 1894 and has updated its guidance as both science and politics have evolved. In the early 20th century, its guidance emphasized recommended minimum servings of important foods; in later decades, its visual guides became more nuanced, illustrating the composition of a healthy diet and encouraging exercise.

Critics argue social media made 'foodie' culture increasingly superficial

For 40 years, being a "foodie" meant possessing knowledge and expertise about ingredients, restaurants, and flavors. Now, the author argues, being a foodie has more to do with documenting aesthetically pleasing meals than critical consumption.
