The flesh of red heart pitaya is not like ordinary pitaya, but presents bright red color. So red heart pitaya is dyed? Red heart pitaya eat more harmful to the body? Let's get to know.
Is red heart pitaya a dyed fruit
Recently, many netizens reported that after eating the red heart pitaya, they found that the urine color was red, and they were worried about whether they were 'poisoned' & hellip; & hellip;
Experts in related fields say that this is a normal phenomenon, which is caused by some natural pigments in fruits that are not decomposed and absorbed, which is harmless to human body.
It is also understood that this year is the first year for the large-scale listing of red heart pitaya in Shanghai. The fruit has a high nutritional value, but it cannot be overeated at one time.
Red heart pitaya should not be eaten too much at a time:
According to Huang Weida, Professor of life science at Shanghai Institute of higher research, Chinese Academy of Sciences, the excretion of red heart pitaya appears red after eating, because the content of natural pigments in this kind of fruit is very high, some natural pigments are not absorbed and decomposed, and these pigments are highly water-soluble, so the excretion of urine and feces will be dyed red.
According to Huang Weida, the purplish red natural pigment in red heart pitaya fruit is not harmful to the health of adults and children, but also has the effect of improving immunity for children. Taking some other colored food will temporarily change the excreta such as urine, which is normal. When you stop taking it, this phenomenon will disappear.
Then, why do you eat the same amount of red heart pitaya fruit? Some people's urine turns red and some people don't change color? This is mainly due to the physical differences of people. For example, the absorption and catabolic capacity of a to this natural pigment is stronger than that of B. after eating the same amount of red heart pitaya fruit, the urine of a may not change color obviously than that of B.
Reminder: 'red heart' has higher nutritional value, but eating more will cause diarrhea
Red heart pitaya is more expensive than white heart in the market, which is the general impression of consumers. In addition to yield and market factors, there are also factors of fruit value. Generally speaking, red heart has higher nutritional value than white heart in some aspects.
According to Huang Weida, red heart pitaya is indeed more nutritious and sweet than ordinary white heart pitaya. Its anthocyanin content is higher than that of pitaya, but its sweetness has little to do with the anthocyanin content. Anthocyanins are not only helpful to eyesight, but also have anti-oxidation, anti-aging and anti-cancer effects.
It is worth mentioning that pitaya has the function of lubricating intestines. Eating too much at a time may cause diarrhea. It is suggested that 'no more than 1000 grams per day' should be used.
