Wrong! The National Health Promotion Administration and many studies have pointed out that drinking flush indicates that the ALDH2 gene, essential for metabolizing toxic aldehydes generated from alcohol, is defective! Approximately 45% of Taiwanese carry this defective ALDH2 gene, ranking the highest carrier rate in the world. About 540 million people in East Asia (Korea, China, Japan, etc) carry this gene defective ALDH2. People carrying this defective ALDH2 drink alcohol will have facial flush, and the risk of oral or esophageal cancer will increase by 20 times. Therefore, no drinking is the best policy!
Not only oral and esophageal cancers, but people with this defective ALDH2 gene cannot metabolize many harmful aldehydes in the body. If they drink, the risk of other cancers, cardiovascular, metabolic, liver, and kidney diseases increases.
Several countries worldwide have recently revised their drinking guidelines, clarifying that there is no safe value for alcohol intake and drinking as little as possible.
