Even nutritious things cannot be gluttonous
In the past, dad always liked to say, "Your grandmother loved to eat apricots when she was alive, and now she can't eat such delicious apricots anymore"!
The apricot is round like a ping-pong ball, it not only has a beautiful appearance of yellow tenderness, but also tastes very good.
In the past, Grandma once picked a lot of apricots back, some apricots are not yet ripe, not fully ripe amygdal acid with sweetness, that time gluttonous, eat too much, teeth become sour and soft, even for several days the teeth are sour and soft, even the tofu can not bite.
Mom said: "Gluttony is not good, apricots can not eat more", I was very strange at the time, why can't sour apricots eat more?
I found white rice vinegar, a clear glass cup, and an egg. I poured the white rice vinegar into the glass about two-thirds of the way through. Then soak the eggs completely in white rice vinegar and let stand for a while. After some time, a closer look reveals a layer of small bubbles on the eggshell.
Half a day later, the egg was taken out and gently pressed with his finger on the egg shell, and the egg shell turned soft!
It turns out that the eggshell contains calcium carbonate, vinegar is an acidic substance, and the two produce a chemical reaction together, and the eggshell becomes soft. In the same way, apricots are more acidic, if we eat more, the acidic components contained in apricots will corrode the teeth, make the teeth bad, and the calcium, phosphorus and protein in the human body will also be decomposed by it, which is very unfavorable to teenagers who are in the physical development period.
Lying in bed at night, I thought about looking at my teeth with a small mirror and found that there were some "little black holes" on my teeth, and I thought who "dug" the little black holes on our teeth? Dad said, "Peach, plum, apricot, spinach, these can not eat more Oh!" ”
I asked "Huh?" Why? ”
Father said that peaches are rich in nutrients, especially high in iron content, and if they are eaten often, they can play a role in preventing and treating anemia. However, even nutritious food can not eat too much, if you eat peach as rice, it is easy to catch fire. The strong acidity in fresh apricots will cause the acid in the stomach to surge, causing stomach problems. And plums belong to cold food, more food will make people phlegm, make the gastrointestinal vigorous peristalsis, spleen and stomach weakness and gastrointestinal indigestion people should eat less. Spinach contains a lot of oxalic acid, oxalic acid in the human body encounters calcium and zinc to form calcium oxalate and zinc oxalate, resulting in the body is not easy to absorb calcium and zinc, resulting in the lack of calcium and zinc in the human body.
That's why, even nutritious food can't be gluttonous!
