I saw a short article on Love Shanghai Forum: "Potato Roast Beef is Toxic", which also pointed out: "Because the concentration of gastric acid required by potatoes and beef during digestion is different, it is bound to prolong the residence time of food in the stomach, which will lead to the prolonged digestion and absorption time of gastrointestinal tract, which will inevitably lead to the disorder of gastrointestinal function over time."
There is also such a scary article in Xici: "Twelve poisonous dishes! Potato roast beef ranks first! " The statement is in line with the previous one, word for word: "Because the concentration of gastric acid required for digestion of potatoes and beef is different, it is bound to prolong the residence time of food in the stomach, thus prolonging the digestion and absorption time of gastrointestinal tract. Over time, it will inevitably lead to gastrointestinal dysfunction. " More articles about the "toxicity" of roast beef with potatoes are also explained in this way, which seems to be "quoting" each other.
"Potatoes and roast beef are poisonous", which expert said it, I can't find it; It is not clear where the "poison" of roast beef with potatoes is. Are you bluffing again?
The netizen exclaimed: I can't eat anything! It is really "talking about color change"! Fortunately, the situation is far from so bad! You can rest assured to eat potatoes and roast beef.
Set things right: experts refute the theory that home cooking is poisonous;
Have you ever thought that fragrant potatoes, roast beef and shallots mixed with tofu will be labeled as "toxic" one day? Recently, a number of print media published the article "Beware of Twelve Kinds of Poisonous Home Cooking", and a life program of Beijing TV also broadcast a feature film with this theme, with the network-related reprints exceeding100000 times, which caused great repercussions among the people.
However, Fan Zhihong, an associate professor at the College of Food Science of China Agricultural University, told the reporter of Life Times that from a professional point of view, most of the statements are ridiculous, and these dishes are not "toxic" at all. Let's ask her to comment on them one by one. The following is Dr. Fan's comments on roast beef with potatoes:
Cause of poisoning: Because the concentration of gastric acid required for the digestion of potatoes and beef is different, it is bound to prolong the retention time of food in the stomach, thus prolonging the digestion and absorption time and leading to gastrointestinal dysfunction.
Comment: Starch cannot be digested in the stomach at all, but only in the small intestine. And because beef contains protein, it can delay the speed of starch entering the small intestine and prevent the blood sugar from rising too fast. If eating starch containing protein is harmful to health, then rice, steamed bread and noodles can't be eaten with fish, meat and eggs. Aren't human eating habits going to be completely subverted?
