10. Milk tea kills sperm, resulting in male infertility
Rumor content:
According to an article, milk tea is the killer of spermicidal, which not only causes the male to lose fertility, but also may induce other diseases. The reason is that milk tea usually contains flavors and pigments, and even contains a lot of trans fatty acids. These substances affect human reproductive health and even lead to infertility.
Truth:
"Milk tea kills delicate infertility" has been popular for many years, but it is exaggerated and misleading. 'pearl milk tea' and other drinks made with milk essence may contain trans fatty acids (this problem will not exist as long as avoiding the use of hydrogenated oil). Some epidemiological surveys show that the population with high intake of trans fatty acids has lower sperm quantity and vitality. However, this is only an epidemiological survey, indicating that the two are related, which does not prove whether the low sperm motility is caused by trans fatty acid or other characteristics of the population with high trans fatty acid intake.
