How did Egyptians keep food cold?

“Egyptian, Roman, and Persian societies used the idea to store food by simply resting two terracotta pots, one over the other, and filling the space in-between with sand and water. As water evaporates from the sand, it removes the heat thus keeping the pot above, where food is kept, at cooler temperatures.”

Asia accounts for more than half of global food waste due to a lack of adequate infrastructure but a technique practiced by early Egyptians could help resolve the modern-day problem. The continent is home to the world's hungriest—a third of the extreme poor live in South Asia, according to the World Bank—but edible food still gets lost or wasted on a massive scale. Per capita food loss in South/Southeast Asia is around 120-170 kilograms a year, versus the region's total per capita food production of 460 kilograms a year, estimates the United Nations (UN). "Some of the causes for wastage include out-dated or bad agricultural practices, poor roads and infrastructure, including the lack of cold storage and refrigerated trucks," explained researchers Tamara Nair and Christopher Lim of Singapore's Nanyang Technological University in a new note. The bulk of food wasted is at the post-harvest, storage and transport stages, not at the consumption end, they observed, noting that India loses up to 40 percent of fruit and vegetable output because of poor refrigeration. Securing financial capital to install proper equipment can be tough for farmers in emerging economies so Nair and Lim recommended an answer that doesn't use electricity: Evaporative cooling. "Egyptian, Roman, and Persian societies used the idea to store food by simply resting two terracotta pots, one over the other, and filling the space in-between with sand and water. As water evaporates from the sand, it removes the heat thus keeping the pot above, where food is kept, at cooler temperatures." The contemporary equivalent of terracotta pots is the Evaptainer, a lightweight device made out of durable and easily available materials that uses evaporative cooling to store food. Developed by a team at the Massachusetts Institute of Technology, the box-like product can store fresh produce at 30 degrees Celsius below ambient temperatures using non-potable water. "Just add water and the Evaptainer does the rest," the start-up proclaims on its website. Evaptainer

Can your stomach shrink from not eating?

Myth or Fact: If you cut down on your food intake, you'll eventually shrink your stomach so you won't be as hungry. Answer: Myth. Once you are an adult, your stomach pretty much remains the same size -- unless you have surgery to intentionally make it smaller.

From those burning, churning feelings that erupt whenever we eat our favorite foods, to the bloating that keeps us from zipping up our jeans, to the gas that can make us the most unpopular person in the elevator, our stomach can be the cause of some major inconveniences, if not some outright health concerns. Still, experts say most folks know painfully little about how their stomach and their digestive tract operates -- one reason that solving tummy troubles can seem much harder than it has to be. "There are some very popular misconceptions concerning stomach health, most of which can really lead people astray on how to effectively deal with certain problems," says Mark Moyad, MD, director of preventive and alternative medicine at the University of Michigan Medical Center in Ann Arbor. David Greenwald, MD, agrees. "Sometimes what seems like a complex, difficult or even frightening problem really is a simple one, with a simple solution, if you can separate the myths from the facts," says Greenwald, an associate professor at the Albert Einstein College of Medicine and Montefiore Medical Center in New York City. To help set the record straight, Greenwald, Moyad, and NYU director of pediatric gastroenterology Joseph Levy, MD, helped WebMD prepare the following gut-busting challenge. Try to separate the myths from the facts to see how much you really know about how to keep your tummy healthy and happy.
