Americans are eating healthier and paying more attention to food than they have in a decade.

They aren’t the only ones to benefit from advances in agriculture and farming. U.S. innovation is helping reduce hunger and malnutrition around the globe.

More needs to be done. By 2050, the world will have another 2 billion mouths to feed. How can we produce enough food — and do it sustainably?

That question is at the heart of the 2015 World Expo in Milan, taking place from May 1 to October 31. The USA Pavilion, titled “American Food 2.0: United to Feed the Planet,” showcases the United States as a food innovator.

Interactive exhibits highlight how U.S. farmers, scientists, businesses and government agencies are working to find ways to feed the world’s growing population.

That spirit of innovation is built into the USA Pavilion itself, which was designed to include technology currently in use to create more sustainable, accessible food ecosystems.

It features the world’s largest vertical farm, where 42 varieties of fruits, vegetables, grains and herbs are being grown in containers made from recycled plastic bottles.

Sustainable technology isn’t the only American innovation on display. At the Food Truck Nation exhibit, visitors can try the culinary traditions and regional products that have transformed the U.S. food landscape into one of the most diverse — and delicious — in the world.

The Feeding the Accelerator project is another highlight of the USA Pavilion. In addition to workshops and demonstrations, the program brings entrepreneurs, chefs and researchers to Milan to collaborate on groundbreaking solutions to global food challenges.
