Tofu

Tofu or bean curd is a food prepared by pressing the curds of coagulated soy milk into solid white blocks of varying softness: 'silken', 'soft', 'firm', and 'extra (or super) firm'. It originated in China and has been consumed for over 2,000 years. Tofu is a traditional component of many East Asian and Southeast Asian cuisines; in modern Western cooking, it is commonly used as a meat substitute. Nutritionally, tofu is low in calories, while providing a rich source of protein. Cultivation of soybeans has one of the lowest needs for land use (1.3 m2/ 1000 kcal) and emits some of the lowest amounts of greenhouse gas emissions per gram of edible protein of any food (1.6 kg CO2/ 100 g protein).
