Yeah, it's called "faith in a cause".

One interesting thing about the nutrition supplied to the common soldiers; they may not have had much, or sometimes even any, food, but they had barrels of apple-cider vinegar. The nutritional benefits of vinegar date back to the ancient Greeks (though they had wine vinegar). Apple cider vinegar is rich in enzymes & potassium, a natural antibiotic germ fighter, fights E Coli and other bacteria, helps control and normalize weight, helps improve digestion assimilation, helps relieve arthritis stiffness, helps relieve dry sore throats, helps remove body sludge toxins.

Of course they didn't itemize or even talk about the exact nutritional benefits of apple cider vinegar but they did know it was good for them in times of little or no food.
