I don't do this at home but at work, I have at least a pound of condiments hoarded from many take-out lunches as well as a lot of napkins and plastic cutlery.
I've never considered the nutrition of these but now that you think about it, the mind boggles at the possibilities
- Honey - Sweetener/First Aid
- Ketchup - Sugar/Salt/Calories (though not as many as you'd think)
- Soya Sauce - Salt/Electrolytes
- Hot Sauce - Flavor (most hot sauces don't have much of any nutritional value)
- BBQ Sauce - Sugar/Calories
- Mustard - Fiber/Vitamins
Unfortunately you'd need to eat a lot if you happened to be trapped in your office with nothing but a big bag of Arby's Sauce packets. They're only 15 calories each and really have no nutritional value beyond containing Iron. The thought of downing 100-150 a day to meet my BMR makes me feel ill.
