according to the sam's club e-commerce platform, the mineral water is called weak alkaline natural mineral water and comes from the longevity mountain in bama, guangxi. bama is recognized as a longevity town. as of september 2023, there are 6,455 people over 80 years old in the county, accounting for 2.73% of the total population, including 102 centenarians. the proportion of long-lived elderly people ranks first among the world's five major longevity towns.

drinking weak alkaline water is good for having children? experts: nonsense

in fact, the term "baby-giving water" is not something that has only recently appeared on the internet. reporters found that last year, a netizen posted that this weakly alkaline mineral water can change the acid-base constitution. if the man insists on drinking it for more than half a year, it can improve sperm activity, and an alkaline constitution can increase the probability of having a boy. the basis is that the y chromosome is believed to be more active in an alkaline environment, and the combination of an egg and a y-shaped sperm can give birth to a boy.

in the opinion of zhang fengbin, deputy chief physician of the andrology department of the obstetrics and gynecology hospital affiliated to zhejiang university, acid-base constitution is a pseudo-concept. the human body has a sophisticated acid-base balance mechanism, which can maintain the body's acid-base balance through regulation of the buffer system (bicarbonate, phosphate and protein), respiratory system and kidneys, so that the ph value of human blood is stabilized in the slightly alkaline range of 7.35-7.45. the body's acid-base level cannot be changed by eating or drinking certain foods or liquids.

"according to current research, there are some drugs, health products and foods that can help regulate sperm activity and improve fertility, but the effect of weak alkaline water in regulating and improving sperm quality is not obvious," said dr. zhang fengbin.

as for the statement that "the y chromosome is more active in an alkaline environment", there is no scientific basis for it.

doctor zhang fengbin mentioned that since human evolution, the gender ratio has reached a balanced state, which belongs to a stable ecological cycle. if this cycle is artificially broken, it will inevitably affect human development. therefore, it is recommended that you do not deliberately pursue the gender of the baby. both boys and girls are good. health is the most important thing.

as early as 2017, the shenzhen health commission's official wechat account announced that the acid-base constitution itself is a pseudo-concept that has nothing to do with the acid-base reaction of food and has nothing to do with whether the baby is a boy or a girl.

sam responded: there is no scientific basis for the online claims

on september 2, sam's club customer service responded to a media interview and said that the product was sam's own-brand product and was just ordinary mineral water. the claims circulating on the internet had no scientific basis. at the same time, the manufacturer also said that they did not spread such claims.

in addition, sam's customer service also responded to the media saying that "this product is just an ordinary commodity and does not have any health care, disease prevention or treatment functions." "this product is an ordinary food and does not involve any health care or disease prevention/treatment functions. please do not believe in rumors and consume rationally."
