"The non-stick pot is poisonous and can cause cancer!" Not quite

stir-fry sticky pot, is a very annoying thing, so, non-stick pot out of the sky undoubtedly for many housewives to solve this big problem. But now there are a lot of voices telling you, "The non-stick pot is poisonous and can cause cancer!" "For this kind of extreme title related to daily life, the editor always feel the need to examine, so, "West Lake Nutrition" small partner for you to consult the data, careful analysis, and then responsiblely tell you: non-stick pot surface coating does contain the likely cancer-causing ammonium perfluoroobonate (
PFOA
), but,
,
is often important!
as
as long as the correct use of non-stick pot, control the temperature, mainly do not use it to stir-fry vegetables, frying, is safe!

whatis a non-stick pot?know if a non-stick pot is toxic, you first need to know what it is.non-stick pot, that is, cooking stir-fry will not stick to the bottom of the pot pot, because the bottom of the pot is non-stick coating, the common non-stick coating has Teflon (
Teflon
) coating and ceramic coating. What we're going to talk about today is whether it's going to cause cancer, which is a non-stick pot coated with Teflon.Teflon, chemically famous Teflon (
PTFE
), Teflon itself is chemically stable. What raises questions about the safety of "non-stick pots" is another chemical used in the production of Teflon, called ammonium perfluorooxine (
PFOA
).
teflon
is a scapegoat, okay?
#Possible carcinogens: Ammonium perfluorooxine (
PFOA
)ammonium perfluorooltanoic acid (
PFOA
) is used to secure the Teflon coating firmly to the surface of the kitchenware. Laboratory data show that high doses
PFAA
exposure to cancer in animal models.
PFOA
also lead to elevated cholesterol levels, thyroid disease and infertility. To make matters worse,
PFAA
also found in blood samples and environments in the population., it must be noted that no studies have shown that the
PFOA
detected in the blood of the population originated from the use of Teflon kitchenware. Although
PFOA
can also be detected in some public water sources, scientists do not know how
PFOA
enters our environment. Because in addition to Teflon manufacturing,
PFOA
is also widely used in the manufacture of other products, including rain jackets, fabric protective layers, fire casings and sealing straps, so
PFOA
can enter our environment in a variety of ways., on the other hand, the vast majority of PFOA products in non-stick
have
destroyed. Therefore, in non-stick pot kitchenware finished products,
content
PFOA should be extremely small.Is it safe to use a non-stick pan on a daily basis?study, published in the journal
Food Additives and Contaminants
, tested
26,
different brands of non-stick pot kitchenware and found
At
degrees celsius
30
minute heating, all tested non-stick pan kitchenware showed no significant pyration and did not release any chemicals

.However, if not properly used non-stick pot kitchen utensils, such as Chinese special love and other oil burning smoke before the ingredients under the pot, this practice will lead to temperatures of more than
230
degrees Celsius, and the heating temperature is too high, it does bring the decomposition of the coating and the release of toxic gases. The non-stick pot coating produces
pyride
300 degrees Celsius, with no significant stimulation. Heating

4
hours above
400 degrees Celsius can produce hydrolysed fluorides such as hydrogen fluoride, which have a strong stimulating effect on the
lungs
so non-stick pots are not suitable for frying food, like rice cookers with non-stick pots is safe. Summary Non-stick pots coated with
Teflon
do contain substances that are likely to cause cancer, but current research data suggest that non-stick pot kitchenware has no significant adverse effects on human health as long as they are used properly. So ah, "non-stick pot toxic, will cause cancer" argument, is not completely correct! Precautions for safe use of non-stick pans -
Never place non-stick pans unattended on open flames or other heating equipment -
when cooking with non-stick kitchenware, the temperature must not exceed
230
degrees Celsius. If dry-burned, or fried at high oil temperatures, the temperature exceeds
230
degrees -
avoid scraping non-stick kitchen surfaces with metal appliances -
be careful to avoid wear when cleaning non-stick kitchenware (unusable wire ball cleaning non-stick pot)
