Coffee is not just a pick-me-up beverage—in recent years, research has also found that it has potential benefits for the digestive system. A 2023 systematic review and meta-analysis published in the journal Nutrients, which included more than 430,000 participants, explored the association between coffee intake and the risk of irritable bowel syndrome (IBS). The results showed that, compared with non-coffee drinkers, people who drank coffee had a 16% lower risk of developing IBS. This protective effect may be related to the antioxidant and anti-inflammatory properties of components in coffee such as caffeine, polyphenols, diterpenes, and trigonelline. However, the effect of coffee on relieving IBS symptoms varies from person to person, and the study itself has observational limitations. This article will provide a detailed interpretation of this study and explore the possible effects of coffee on gut health. [more…]

In recent years, coffee enemas have attracted attention online as a so-called detox therapy, even appearing in product sales. This article traces the historical origins of this therapy, sorts out its claimed benefits, and, drawing on medical perspectives, points out that coffee enemas lack supporting research evidence and that long-term practice may disrupt gut flora and cause serious consequences such as burns or perforation. At the same time, drinking coffee itself can gently promote bowel movements, so there is no need to risk enemas. At the end of the article, Front Street Coffee's professional information channels are also retained for enthusiasts to communicate. [more…]

Around 2.25 billion cups of coffee are consumed worldwide every day, and with that comes a massive amount of spent coffee grounds. Traditional recycling methods—such as deodorizing, exfoliating, or making furniture—often require drying, which actually releases carbon dioxide. Japanese scientist Tetsuji Ishigaki has taken a different approach: using Aspergillus to ferment spent coffee grounds into a paste, then adding cocoa butter to solidify it, creating a ready-to-eat spent-coffee-ground chocolate. This product, called COLEHA, not only contains three times the amino acids of green coffee beans, but its polyphenols and antioxidants also reach 1.6 times those of regular coffee, and it is rich in insoluble fiber that promotes gut health. COLEHA is currently available in limited quantities, with sugar content offered in three versions—0%, 10%, and 40%—each with its own distinctive taste. This article introduces this eco-friendly and innovative spent-coffee-ground utilization technology, along with the flavor and health secrets behind it. [more…]

Black tea, one of the most widely consumed types of tea in the world, traces its origin to an accidental oxidation event in Fujian, China, in the 17th century.

After Luckin Coffee launched its Prune Latte, social media platforms saw a surge of discussions about gastrointestinal reactions after drinking it, even jokingly dubbed the "suppository of the coffee world."

Guming obtained approval for a Hong Kong listing filing, becoming the first company to receive the green light amid the new tea beverage IPO wave. Meanwhile, its winter new product "Dark Chocolate Mocha" has drawn attention for its rich cocoa flavor, but has also been jokingly called a "great gut cleanser" due to a large number of consumers reporting diarrhea after drinking it.

Bulletproof coffee has become a hot topic in fat-loss circles in recent years.

Luckin Coffee once brought back several classic drinks due to popular demand from netizens, and now the much-anticipated Heart Stealer Prune Latte is also set to return next week. However, while unpacking the new product materials, employees unexpectedly discovered that in addition to the usual paper bags and cup sleeves, there was also a pack of tissues printed with the word "prune." This thoughtful yet slightly humorous move quickly sparked discussions among netizens: some joked that the company was worried consumers would frequently run to the toilet after drinking it, while others speculated that the recipe might have been adjusted. The prune latte became famous back in the day for its "smooth movement" effect and was jokingly called "the coffee world's suppository."

This new addition to their tea-coffee series, which uses Wuyi Mountain Da Hong Pao as its tea base and offers an optional oat milk version, quickly sparked discussions among netizens after its launch. Apart from its taste being compared to Assam milk tea, what drew even more attention was its post-consumption "smooth" effect—a large number of consumers on social media reported feeling the urge to use the restroom shortly after drinking it, with some making multiple trips in a single day, jokingly dubbing it the "new toilet-busting divine water." Some speculate this is related to the thick milk component in the drink and lactose intolerance. Although the effect varies from person to person, this unintended function has actually tempted many netizens who were previously uninterested to give it a try. [more…]

How many times can Zhengshan Xiaozhong Gongfu black tea actually be re-steeped? And for two people, how many grams of tea leaves should be weighed out? The answer lies in the water used, the tea-to-water ratio, and the rhythm of pouring. This article begins with water treatment, explaining why mineral water or mountain spring water is preferable, why tap water must be boiled to remove chlorine, and how scale and frequent water changes affect the taste of the tea; it then gives the general ratio of 40 milliliters of water to 1 gram of tea, and demonstrates the steps of warming the vessel, adding the tea, and a one-minute first steep. The key point is that after the second steep, almost no covered steeping is needed—simply letting boiling water skim over the leaves is enough, and only in this way can six consecutive steeps still carry flavor. The same principle applies to Front Street black tea. [more…]

Bulletproof coffee has spread from Western entertainment circles to fitness circles and weight-loss forums in recent years, becoming a beverage that attracts considerable attention.
