It is reported that the tomato contains nicotine, which caused many people to panic. Experts rumored that the nicotine content of the tomato is very small, and can not be compared with cigarettes. Let’s talk about nicotine in various foods.
Nicotine is a highly toxic ingredient. I have seen from a young age that a horse that is alive and kicking can be killed by intravenous injection of 8 drops of nicotine. The nicotine contained in a cigarette is extracted and injected into the mouse. . The taste of cigarettes can keep all kinds of animals and insects away because they instinctively know that tobacco is poisonous. However, nicotine is also a strong addictive ingredient, and smokers are so obsessed with smoke, mainly because of it. It is exciting and calm. It raises blood pressure and is harmful to the cardiovascular system.
In fact, in addition to tobacco, people have long discovered that other plantaceae also contain nicotine. Among the Solanaceae plants, many varieties are loved and cultivated by humans, such as delicious eggplant, tomato and sweet pepper, the darling pepper of the condiment, and the potato that is regarded as the staple food by Europeans.
Even if the nicotine content of these vegetables is extremely low, there are always people who are worried about “how to do if there is a small amount of toxic substances accumulated for a long time”. In fact, there is no need to worry, because the metabolism of nicotine in the human body is very fast. Otherwise, there is no way to understand why smokers inhale so much smoke every day. If the nicotine that is smoked every day is taken out for intravenous injection, the amount far exceeds the lethal dose and can survive for decades. Because nicotine is a small intake, and then quickly detoxification metabolism.
Recent studies have shown that some mushrooms contain higher levels of nicotine. Research data received by the European Food Safety Authority (EFSA) have shown that the concentration of nicotine in wild mushrooms such as boletus and truffles is as high as 0.5 mg/kg. However, further studies have found that nicotine is a natural metabolite of the fungus itself and is not a contaminated residue of nicotine pesticides. Given the small daily intake of fungi, nicotine is unlikely to pose a threat to human health.
