The Salt Lake Tribune has an interesting story titled “Meat Eaters Try Martian Fare and Learn to Like Lentil Loaf,” which discusses a Cornell University experiment where researchers were looking to create a diet for the first human inhabitants of Mars. The diet was dairy and meat free (and presumably egg-free as well), consisting largely of beans, grains, and setian. All of the participants were omnivores who lost weight, but steadied at their new weight, on their new vegetarian diet. Not surprisingly, they returned to their previous weight when they returned to their normal diet.
Though the article doesn’t really present anything we didn’t already know about vegetarianism’s health benefits, it takes a look at the issue from a unique perspective.
