Natick, Mass. -- Despite military chow's lousy reputation, many products that Northern California grocery shoppers buy every day have come from innovations created for the battlefield.

M&Ms were invented so World War II fighters could enjoy chocolate that didn't melt in the heat of the Pacific. Similarly, tins of processed Velveeta cheese and Spam became prominent parts of the American diet after thousands of World War II soldiers survived on the processed food.

Freeze-dried coffee and soup mixes, chopped and formed meat and lightweight backpacker entrees all have come from military needs. So did something called "retort packaging," a heat and water process much like canning that keeps plastic pouches of food shelf-stable for years. Even McDonald's boneless McRib sandwich came from technology developed by the Department of Defense's Combat Feeding Directorate.
