Recently, a weakly alkaline natural mineral water sold at Sam's Club was snapped up and went out of stock after rumors spread that "if the father drinks it, he can have a son," and the related topic topped Weibo's hot search list. This product, which meets the GB8537 standard and costs about one yuan on average, comes from Bama Longevity Mountain in Guangxi. It was originally just ordinary mineral water, but because of its "weakly alkaline" label, it was credited with effects such as neutralizing stomach acid, lowering uric acid, and even helping couples conceive a boy. Although the Shenzhen Health Commission long ago debunked the "acidic/alkaline constitution" as a pseudoscientific concept, and Sam's Club customer service also responded that there is no scientific basis for it, many netizens on social platforms still shared experiences of "it worked for me" and even summarized a "best drinking guide." This article will retrace the whole incident, explore the social psychology behind the rumor, and remind readers: whether a baby is a boy or a girl is random, and the baby's health is what matters most.

Whether tea is acidic is especially critical for people suffering from heartburn or acid reflux. The pH values of different types of tea vary significantly: black tea tends to be acidic, while green tea may be close to neutral or even alkaline. The factors affecting the acidity of brewed tea go far beyond the type of tea—the amount of leaves used, brewing temperature, steeping time, and whether tea bags are used all influence the final result. In addition, the caffeine in tea relaxes the esophageal sphincter, which may worsen reflux symptoms. If tooth pain occurs after drinking tea, it may also be related to acidity. This article systematically sorts out the relationship between tea and acidity, and includes recommendations for tart black teas, helping coffee and tea lovers enjoy flavor while also looking after their health.

The relationship between coffee and gout has always been a topic of concern for coffee lovers. In the past, people worried that caffeine metabolism would raise uric acid levels, but in recent years, multiple studies have pointed to the opposite conclusion. A large-scale study jointly conducted by the National Defense Medical College of Japan and Osaka University, involving more than 150,000 Japanese people, analyzed the association between the number of days per week of coffee consumption and uric acid levels and the incidence of gout. The results showed that for each additional day per week of coffee consumption, the risk of developing gout could be reduced by about 25%. This finding provides new data support for coffee's role in preventing gout and has also prompted further thinking about coffee components and the mechanisms of gout. This article will review the core conclusions of the study, previous research evidence, and expert opinions to help readers scientifically understand the relationship between coffee and gout.

Can you drink coffee after contracting COVID-19? This has been the most frequently asked question in our inbox recently. Based on the personal experiences of many coffee lovers, the answer is not absolute—it depends on individual constitution and specific symptoms. When experiencing heart discomfort, fever, severe sore throat, or right after taking medication, you need to be especially cautious or even temporarily stop drinking coffee; whereas with mild to moderate headaches, a moderate amount of coffee may actually help relieve them. If you really want to drink coffee, pour-over is a relatively safe choice since the paper filter makes the coffee cleaner. There's no need to feel it's a waste if you temporarily lose your sense of taste or smell—drink it if you want to, as it might even help promote the recovery of your senses. Freshly roasted beans only have a peak flavor window of 30-40 days, so don't let good beans sit around until they expire. [more…]
