Not all food is fresher, the better

　　Eat raw egg
　　
Some people believe that eating raw eggs can moisturize the lungs and throat. In fact, raw eggs contain "avidin" and "antitrypsin". The former can affect the body's absorption and utilization of protein, and the latter can destroy the body's digestive function, so eggs should be cooked and eaten.

　Undercooked vegetables to eat raw

Many people also like to eat half-cooked vegetables, thinking they are tender and delicious. In fact, such vegetables may contain toxins. For example, immature green tomatoes contain a large amount of alkaloids, and eating too much will cause poisoning symptoms such as nausea and vomiting. Fresh kidney beans (also known as green beans and sword beans) contain saponins and hemagglutinin. Those who eat them raw or undercooked are susceptible to poisoning.

Autumn lentils, especially fresh lentils that have been frosted, contain a large amount of saponins and hemagglutinin. Before eating, it should be blanched in boiling water or fried in hot oil until it changes color and is cooked through. Fresh day lilies contain a toxic substance called colchicine. Adults can be poisoned if they eat 50 to 100 grams of untreated fresh day lilies at one time. However, colchicine is easily soluble in water and decomposes easily when exposed to heat, so blanch it in boiling water before eating and soak it in clean water for 1 to 2 hours to detoxify. Dried daylily is non-toxic and can be eaten with confidence.
