Can You Safely Drink Coffee During Pregnancy? New Research Provides Genetic Evidence and Advice on Moderate Consumption

Whether coffee can be consumed during pregnancy has long been a subject of debate.

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…]

Luckin Store Manager Accused of Emotional Involvement with 17-Year-Old Part-Time Girl, Girl's Death from Medication Sparks Concern

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.

A bubble tea franchise store in Wuxi appears to run community group buys and membership top-ups on the surface, but behind the scenes it is suspected of large-scale fraud.

Sam's weakly alkaline mineral water rumored to help conceive boys, triggering panic buying—another clash between science and rumor

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.

What affects the size of the bloom dome in pour-over coffee? An in-depth analysis of freshness, roast level, and extraction efficiency

During the bloom phase of pour-over coffee, whether the coffee bed puffs up into a large dome or stays relatively flat actually hides quite a bit of information.

This time, Front Street Coffee will help everyone understand: why do some beans puff up like a balloon during the bloom while others stay flat and collapsed? What role does carbon dioxide play in this? Why do dark roasts and fresh beans puff up more? How do extraction parameters influence the degree of doming?

Key details in the milk-pouring and integration stage of latte art: how flow rate, pouring distance, and milk volume affect the final result

When making an espresso latte, the success of the latte art pattern often depends on whether the integration step is done properly. When integrated well, the pattern background is clean and the coffee flavor is unified; when integrated poorly, not only does the image look messy, but the mouthfeel also feels disjointed. Front Street Coffee points out that there are three easily overlooked details in the integration stage: the flow rate of the milk being poured, the distance between the milk pitcher and the liquid surface (the pouring distance), and the amount of milk used for integration. This article will break down these three key points one by one, explaining why a low flow rate combined with a high pouring distance is more conducive to integration, as well as the specific requirements for integration milk volume for different latte art patterns, helping you make latte coffee with consistent flavor and a clean image at home.

Analysis of Four Common Mistakes in the Coffee Latte Art Pouring Phase: How Flow Distance, Flow Rate, and Crema Condition Affect the Pattern

When creating latte art, integration is a preparatory step just as important as the bloom in pour-over coffee.
