Our three year food supply comes with a balanced and nutritious variety of 3600 servings. We have studied and researched exactly what we feel will be needed in an emergency or disaster situation when stress levels could be running high and nutrition and food intake is of utmost importance. Our three year supply is measured out for one person for a thirty six month period of time. Like all Eat Tomorrow Foods, our three year supply has a 25 year shelf life and is GMO free.
