How much do you know about caffeine

Caffeine belongs to purine alkaloids. At present, more than 60 kinds of plants are known to contain caffeine, such as coffee beans, tea, cocoa beans, Kola nut (once one of the raw materials for cola beverage extraction), Madai leaves, Guarana and so on. These edible natural raw materials themselves or their extracts are often used in beverage production. The use of caffeine compounds in the food industry is regarded as a flavoring agent in food additives and must comply with the norms for the use of food additives. at present, caffeine compounds can only be added to seasoned drinks in Taiwan. Caffeine intake will stimulate the human central nervous system, cardiovascular, respiratory system, gastrointestinal, muscle and so on, but also increase the speed of cell metabolism, diuresis and so on. For ordinary people, its action time can be up to 3-4 hours.

The "advantages" and "disadvantages" of caffeine on the health of ordinary people have been widely discussed in different literatures, including boosting spirit, increasing alertness, concentration and responsiveness, reducing cardiovascular and neurodegenerative diseases, and even longevity; "disadvantages" include palpitations, sleep disorders, anxiety, irritability, bone health and gastrointestinal function, and may affect fetal health in pregnant women. However, due to the different strength of the literature evidence, professionals are needed to evaluate the validity of these conclusions and their applicability to individuals. The health risk assessment information section of the Food and Drug Consumer knowledge Service Network of the Ministry of Health and Welfare also has a special chapter on caffeine.
