Humans consume grains and cereals, and while the intake of food provides the body with nutrients, it also accumulates a significant amount of toxins. Pears are a fruit loved by many; they are not only fresh, tender, and juicy but also rich in vitamins, dietary fiber, and trace elements such as calcium, phosphorus, iron, and iodine. Eating pears regularly can not only prevent constipation but also promote the excretion of carcinogenic substances from the body.
Researchers conducted an experiment on smokers, having them consume 750 grams of pears daily for four consecutive days, and measured the levels of 1-hydroxypyrene, a metabolite of polycyclic aromatic hydrocarbons, in their urine before and after the pear consumption. The results showed that when pears were eaten 6 hours after smoking, a large amount of 1-hydroxypyrene in the blood was excreted through the urine; without eating pears, very little 1-hydroxypyrene was excreted. Furthermore, heated pear juice contains a large amount of polyphenols, which are anti-cancer substances. When mice injected with carcinogens were given this pear juice, a large amount of the 1-hydroxypyrene toxin was excreted in their urine, effectively preventing cancer. In particular, eating a pear after consuming fried or grilled foods and fast food is a healthy lifestyle choice.
