Soy food

Soy Food  is a low-fat, high-protein food made from processing the soy bean. In Deus Ex, Soy Food is a consumable item, much like candy bars and liquor, though soy heals the player by 5 points, opposed to the usual 2, and has no adverse effects on the player."Soy! - The complete snack! Engineered to provide maximum nutrition -- not a single molecule wasted on added flavor or texture."
