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…]

Naobaijin has once again made its presence felt in the coffee world. This time, it's not just a simple co-branded paper cup—they've actually added Naobaijin oral liquid to the coffee. On November 10, Naobaijin officially announced on Xiaohongshu the launch of a special coffee containing Naobaijin ingredients, which would be sold in limited quantities at a pop-up store on Double Eleven. As soon as the news broke, netizens were both curious and confused: Naobaijin is known for aiding sleep, while coffee is for waking up—what kind of combination is that? The official response stated that what was added was Naobaijin oral liquid, which has a bowel-lubricating and laxative function, not the sleep-aid capsules, and that the amount used per cup had been scientifically calibrated to avoid any functional conflict. So, how does this coffee taste? And what has Naobaijin's journey in the coffee arena been like? Let's take a look. [more…]

A seemingly ordinary lemonade actually claimed the life of a 21-year-old girl. In September 2023, University of Pennsylvania student Sarah Katz drank a beverage called "Charged Lemonade" while dining at Panera Bread, and just hours later, she tragically passed away from cardiac arrest. Her parents recently filed a lawsuit against Panera, alleging that the product contained an alarming amount of caffeine—260mg for a small cup and 390mg for a large cup, far exceeding the content of a can of Red Bull. What is even more concerning is that this drink was marketed as a "clean plant-based beverage," which led Sarah, who had a heart condition, to let her guard down. This incident has once again sounded the alarm about caffeine intake safety. [more…]

In recent years, a "raw coffee" launched by a coffee shop in Nagoya, Japan, has attracted the attention of health scholars and celebrity models. This drink, made by brewing raw coffee beans together with roasted coffee beans, is said to far outperform black coffee in terms of weight loss. A four-week experiment showed that participants who drank raw coffee lost significantly more weight than those who drank black coffee, and the key behind this lies in the abundant chlorogenic acid in raw coffee beans. Chlorogenic acid can improve insulin sensitivity and regulate glucose and lipid metabolism, and has preventive and therapeutic effects on obesity and metabolic syndrome. However, chlorogenic acid is sour and astringent and unpleasant to the taste, and is degraded after roasting. Raw coffee tastes light, with nutty and roasted barley tea flavors, but it still contains caffeine and should not be drunk in excess. This article will provide an in-depth analysis of the weight-loss principles of raw coffee, the mechanism of action of chlorogenic acid, and its essential differences from black coffee. [more…]

Recently, a red guava trend has swept through the tea beverage scene, with brands such as Heytea, Jasmine Milk White, LELECHA, Quchashan, and Grandma Handmade launching seasonal limited-edition guava drinks. Among them, Jasmine Milk White's "Jasmine Pink Guava" and "Matcha Pink Guava," made with fresh-squeezed red guava juice in specialty fruit milk, quickly went viral, with orders flooding in. However, behind these highly photogenic drinks, store employees are crying out in distress—unripe guava flesh is rock hard, and manually scooping out the core and seeds is time-consuming and labor-intensive, leaving many with hand cramps or even carpal tunnel syndrome. To deal with the rock-hard guavas, staff tried ripening methods such as sealing them in plastic bags and placing them alongside bananas, but demand still outstripped supply. Compared with Heytea's approach of blending the fruit directly into smoothies—skin and seeds included—Jasmine Milk White employees, while envious, would rather the brand just discontinue the new products. This article takes you behind the scenes of the guava craze to reveal the hardships of making these drinks and the voices of the employees. [more…]

After the holidays, many people rely on coffee to "stay alive," only to find they're still sleepy after drinking it.
