Tofu is a plant-based protein source made from soybeans, offering a comparable protein content to meat. While the exact protein levels vary, tofu generally provides a substantial amount of protein, making it a popular choice for vegetarians and those seeking alternative protein sources. It is also high in calcium, potassium, and iron.
Tofu vs. Meat: A Protein Content Comparison
| Food | Protein Content (per 100g) |
|---|---|
| Tofu | 6-8g |
| Beef | ~26g |
| Chicken Breast | ~30g |
While meat generally has a higher protein content per 100g than tofu, tofu offers other nutritional benefits and can be part of a balanced diet.
What are the nutritional benefits of tofu?
Tofu is not only a good source of protein but also provides essential nutrients like calcium, potassium, and iron. It is relatively flavourless, so it can be easily added to many dishes.
How does tofu production impact the environment compared to meat production?
The World Wildlife Fund (WWF) has found that producing soy-based proteins like tofu can, in some instances, contribute more to greenhouse gas emissions than locally produced meat. However, beef production is often the most efficient way to produce food for humans, especially considering that approximately 85 percent of U.S. grazing land is unsuitable for raising crops humans can eat.
How is tofu made?
Tofu is made from dried soybeans soaked in water, crushed, and boiled. The mixture is separated into solid pulp and soy milk. Salt coagulants are added to the soy milk to separate the curds from the whey. The soy milk is then poured into molds to allow the carbohydrate-laden whey to drain off.
