7-Eleven didn't make a big deal about it, but Hampton Creek, the makers of Just Mayo announced via Twitter that the convenience store chain is switching to the mayo substitute for the foods it makes. Just Mayo is an eggless mayonnaise made from pea protein.
When my family taste tested Just Mayo, we were impressed. It tasted very good and we would have never guessed it was made differently — and more sustainably — than traditional mayonnaise. We even used it in vegan cupcakes, and according to my teenage son, they were the best cupcakes he'd ever had.
Ecorazzi interviewed Hampton Creek CEO Josh Tetrick about the switch, which should be in effect at all 7-Eleven stores by now. The estimated environmental and health benefits of the switch are impressive. By switching from mayonnaise made with eggs to the plant-based Just Mayo, Tetrick estimates "each year will save over 81 million gallons of water, preserve over 4 million square feet of land, and prevent 191 million grams of CO2 emission. For the body, 1.5 billion milligrams of sodium, 304 million milligrams of cholesterol, and 30 million grams of saturated fat would be avoided annually."
When Fortune contacted the company for a statement, it was told "the company has not issued any information on this topic." Fortune speculates it could be because of the high price of eggs. The cost of eggs has risen due to a shortage caused by an outbreak of avian flu that has infected more than 48 million chickens this year.
Whatever the reason, there doesn't seem to be a downside to this switch. Just Mayo tastes good, is healthier than traditional mayonnaise, and its production takes less of a toll on the environment. Wikipedia reports that as of 2013, 7-Eleven had 8,144 franchises across the United States so the benefits are going to add up.
