1. Cassava is not a sweet potato. Cassava is one of the three major tubers (sweet potatoes, potatoes, and cassava) in the world. In addition to being the main raw material for starch production and processing in industry, it is often used as a daily diet for low-income people in the tropics.

2. Both cassava and sweet potato are rhizome plants with high starch content and low protein content. The difference is that although the roots of cassava are rich in starch, all parts of the plant, including roots, stems, and leaves, contain toxic substances, and fresh roots are more toxic. Mild symptoms of food poisoning include nausea, vomiting, diarrhea, and dizziness; severe symptoms include difficulty breathing, rapid heartbeat, dilated pupils, and even coma, and finally convulsions, shock, and death due to respiratory failure. It can also cause chronic diseases such as goiter, fatty liver, and damage to the optic nerve and motor nerve.
