Is it true that popcorn contains lead?
It's true.
The raw material of popcorn is corn, which absorbs lead from the soil, so popcorn also contains lead. At present, the content of officially sold popcorn is less, which is within the national standard. However, the old street popcorn machine contains a lead sealing machine, which has good ductility. After heating at high temperature, lead will turn into lead vapor and mix into popcorn, which makes popcorn contain a lot of lead.
2. Effects of lead on human body
Popcorn contains a certain degree of lead, and the lead content below the national limit standard is safe. If the lead in popcorn exceeds the standard, lead poisoning may occur, with symptoms such as abdominal pain, vomiting, dizziness, irritability and anemia, which will seriously cause liver and kidney damage. Lead in popcorn can affect the nervous system and digestive system of the body. Lead can affect children's appetite, reduce the brain development of fetus or children, and affect the intelligence level; Severe lead exceeding the standard will also affect the premature delivery and abortion of pregnant women.

Fruits and vegetables rich in vitamin C, such as kiwi fruit, pomegranate and hawthorn; 2. Iron-rich foods such as spinach, lean meat and red dates; 3. Tea is a natural antioxidant, which can prevent lead precipitation.
4. Is microwave popcorn safe?
Although homemade popcorn in microwave oven can avoid lead pollution caused by the machine, the popcorn bag used has safety factors. That bag of popcorn contains diacetyl, which can cause cancer.
5. Can you eat more popcorn?
At present, the qualified popcorn sold in the market all uses stainless steel equipment to replace the traditional old popcorn machine, which reduces the secondary pollution. The lead content of ordinary popcorn is only about 0. 1 mg/kg, which is far below the national limit of 0.5 mg/kg. Therefore, there is no need to eliminate popcorn. But popcorn is high in calories and easy to get angry, so it is not recommended to eat more.
6. Safety reminder
Street-side converter-type explosion pot is relatively backward, and the pot contains lead. When heated at high pressure, a certain amount of lead in the popcorn explosion pot will melt, and some lead will become steam and lead smoke, which will pollute the raw materials. Especially at the last moment of "explosion", lead is more easily adsorbed on loose rice flowers. When lead is absorbed by human body, it will do harm to nervous system, hematopoietic system and digestive system. It is prone to chronic lead poisoning, which can lead to children's loss of appetite, diarrhea, irritability, purple gums, decreased resistance and slow growth and development. In addition, some popcorn also contains a lot of saccharin, which is not good for your health. So parents should not let their children eat this kind of popcorn often.
Now, in order to make the taste of popcorn more attractive, a lot of margarine is added, and some popcorn flavors are added. In order to make the popcorn more beautiful, some pigments were added. He was wearing a beautiful coat.
However, this margarine brings us extra energy and trans fatty acids. Extra energy will bring obesity closer to us. Trans fatty acids can reduce high density lipoprotein, increase low density lipoprotein, and increase the risk of cardiovascular and cerebrovascular diseases. Excessive intake of artificial pigments may lead to ADHD in children.
Of course, as long as we pay attention, additives can still bring us a lot of delicious and fun.
With the progress of science and technology, the popcorn machine has also been greatly improved. Now the popcorn machine made of stainless steel has gradually replaced the converter machine in the past; The popular aluminum popcorn machine in previous years was gradually replaced by stainless steel popcorn machine with people's understanding of the harm of aluminum tableware, and the pollution in production gradually disappeared.
Many high-grade popcorn are made of non-trans fats such as coconut oil and palm oil, and corn itself is nutritious, which can make popcorn delicious and nutritious, so it can also be very healthy!
