The second fruit — oranges
The cultivation of orange has a long history. The ancient people used orange peel as an aromatic substitute. The seeds of this genus were found in the tomb relics of western han dynasty unearthed in mawangdui, a suburb of changsha, hunan province.
Normal orange is very nutritious value, but afraid to meet the black heart business!
In order to make the surface of orange glossy to improve the unit price, some merchants will also use pigment on the skin of orange processing.
If the use of industrial dyes, heavy metal is likely to overspend, may lead to slow poisoning symptoms, affecting the function of internal organs.
Third fruit – rotten apples
Rotten apples are never eaten. When someone eats an apple, he will scratch out part of it and eat it.
In fact, even if the rotting parts are removed, the rest has been fed through juice into bacterial metabolites, and even microorganisms have begun to reproduce, during which mold can cause sudden changes in human cells leading to cancer.
