Do you often have toast for breakfast? Every morning anxious to go out to work, class, many people will choose fast and convenient toasted toast as breakfast.

However, the recent network news said that toast toast for a long time will produce "monochloropropylene glycol" carcinogenic substances, children eat a daily, and adults are two slices may cause cancer.

To this, nephrologist also confirmed, toast had better not exceed this time.

The nephrologist shared a graph of the Pingtung University of Science and Technology study combined with similar studies abroad, which found that "monochloropropylene glycol" was produced when toast was baked.

In the study, white toast, whole wheat toast, Taiwan cream toast, etc., were compared before baking, after baking for 20 seconds, and after baking for 60 degrees.

It was found that there was almost no "monochlopropylene glycol" in the toast that had not been baked, but there were all baked.

The healthiest wholemeal toast was found to have the highest levels of monochloropropylene glycol after toasting, while the rest of the food had no detectable levels before or after toasting.

According to a large WHO study, "monochlorpropylene glycol" can cause cancer of the thyroid, liver, kidney, breast, testicular, etc..

And itself can cause liver, kidney and tongue toxicity.

In addition, in animal studies have also found that "monochloropropylene glycol" will make the tongue of the animal swelling, even the phenomenon of destruction, and the higher the dose, the more mice have cancer.

So many people have begun to pay attention to "monochloropropylene glycol" this carcinogen.

The "monochloropropylene glycol" produced by toasting in 20 seconds will be within the edible range.

However, some processed products in the modern diet, such as chemical soy sauce, contain an excessive amount of "monochloropropylene glycol".

If there are Chinese dishes containing soy sauce, such as dumplings, fish dumplings, Gong balls, and marinated eggs, every day, there is no way to eat more toast.

In addition, doctors also mentioned that a common bread, such as brioche bread, only needs 160 seconds to reach 679ppb.

So eating only two brioche buns would be too much for an adult, while whole-grain toast toasted for 160 seconds would reach 556ppb.

So eating two slices of wholemeal toast would reach an adult's daily dose.

You can't eat any food with chemical soy sauce that day.

The doctor also urged the public to eat less toasted toast.

"Until there are safer data on what can be done to detoxify, it seems safe to leave toast untoasted."
