Whether coffee can be consumed during pregnancy has long been a subject of debate. A team from the Institute for Molecular Bioscience at the University of Queensland published a Mendelian randomization study in the International Journal of Epidemiology, using genetic data to explore the causal relationship between coffee consumption during pregnancy and adverse pregnancy outcomes such as miscarriage, stillbirth, preterm birth, and low infant birth weight. The results suggest that, provided the body's condition allows it, moderate coffee consumption during pregnancy does not necessarily lead to adverse outcomes, but caffeine may still affect fetal development. This article will review the key findings of the study and offer practical advice on coffee consumption and caffeine intake during pregnancy, helping coffee lovers make safer choices. [more…]

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.

Over a thousand local people have fallen victim, with transaction flows of nearly 200 million yuan, and even people in Shanghai, Zhejiang, Anhui and other places have been caught up in it.

Recently, news about a Luckin Coffee store manager who had an emotional dispute with a 17-year-old part-time female employee, which ultimately led the girl to take medication and commit suicide, sparked heated discussion on social media. The girl's family knelt in front of the store to protest, claiming that the store manager used his position to deceive their underage daughter and is suspected of forcing her into a relationship that led to pregnancy, causing enormous psychological pressure on the girl. After investigation, police determined that the girl purchased the medication herself to commit suicide, that the case did not constitute a criminal case, and that it would not be filed. The judicial authorities organized two mediations, but the man said he was unable to pay compensation. After the incident was exposed, the store manager involved had resigned, and Luckin officially responded that it had not received any relevant notice.

Many coffee enthusiasts are in the habit of tapping the dripper during pour-over to level the coffee bed, believing this promotes more even extraction. But you may not know that frequent or forceful tapping can actually trigger the "Brazil nut effect," causing fine particles to sink to the bottom and coarse particles to float up, leading to two negative outcomes: first, during blooming, hot water struggles to evenly saturate all the coffee grounds, and the fine particles at the bottom stay dry, resulting in under-extraction; second, the fine particles clog the pores of the filter paper, prolonging the extraction time and causing over-extraction. Through repeated testing, Front Street Coffee has found that when using a conical dripper and denser coffee grounds, digging into the bed after multiple taps often reveals dry clumps at the bottom. So how should an uneven coffee bed be handled? And what should you watch out for when tapping? This article will break it down for you in detail. [more…]

PFAS, a chemical commonly found in takeout containers, effectively repels oil and water but poses a serious threat to the environment and human health because it is difficult to degrade. This article will provide an in-depth interpretation of Starbucks' elimination plan, the hazards of PFAS, and the cost challenges facing alternatives, while also highlighting the sustainability efforts of brands such as Front Street Coffee.

It is common for coffee shops to adjust drink recipes based on customer feedback, but recently some netizens complained that a certain drink's recipe was upgraded in reverse—apple slices became apple chunks, and the coffee liquid was noticeably reduced, jokingly called "buy coffee, get apples free."

With the same coffee beans, switching to a different dripper can result in a completely different flavor in the cup. The shape of the dripper determines the distribution of the coffee bed, while the design of the ribs affects the flow rate and the contact time between water and coffee grounds.
