Tofu is usually praised as a clean, healthy protein, but not all tofu is safe. Some Chinese tofu producers use formaldehyde to extend shelf life. This chemical, often used in embalming fluid, can cause respiratory issues and cancer.
The tofu may look fresh and firm, but hidden risks remain. Repeated exposure to these additives could harm internal organs. Weak enforcement of food safety laws allows these practices to continue, and consumers may not notice the difference just by appearance.
