Coffee has become a beverage with enormous global consumption, and its market in China continues to expand. More and more research has focused on coffee's effects on health, but previous studies have often overlooked the distinction between whether sugar is added or not. In 2022, a team from Southern Medical University published a paper in the Annals of Internal Medicine, using data from more than 170,000 people in the UK Biobank to analyze the relationship between unsweetened, sugar-sweetened, and artificially sweetened coffee and mortality risk. The results showed that moderate consumption of both unsweetened and sugar-sweetened coffee was associated with a lower mortality risk, but the amount of sugar added to sugar-sweetened coffee was far lower than that in commercially available fancy coffee drinks. This article interprets the core findings of that study and reminds consumers who like high-sugar coffee to pay attention to the difference. [more…]

Drinking coffee and tea not only boosts alertness but may also protect our brains. A new study from Tianjin Medical University, published in PLOS Medicine, based on long-term tracking data from more than 360,000 people in the UK Biobank, has for the first time revealed the link between coffee and tea intake and the risk of stroke and dementia. The study found that moderate daily consumption of coffee or tea, or a combination of both, can reduce the probability of stroke and dementia to the lowest level. However, excessive coffee consumption may instead increase the risk of dementia. So how much is best to drink each day? And how do coffee and tea exert their protective effects? This article will explain in detail the key findings of this study. [more…]

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.

Coffee is a commodity with global trade volume second only to crude oil, and its consumption growth in the East is particularly rapid, which is why scientific research surrounding it and human health has continued to deepen. Interestingly, the conclusions of related studies are not consistent: some have found that drinking coffee can slow cognitive decline, while others suggest that excessive consumption may shrink brain volume and increase dementia risk. This article reviews several representative cohort studies from around 2021, involving findings from Edith Cowan University in Australia, Tianjin Medical University, and the University of South Australia, attempting to clarify the complex associations between coffee intake and Alzheimer's disease and stroke, and to explore the relationship between the number of cups consumed daily and the safe upper limit of caffeine.

Prolonged sitting has become an unavoidable part of modern life, and its health risks are drawing increasing attention. Multiple studies have confirmed that prolonged sitting raises the risk of cardiovascular disease and other chronic conditions, and can even shorten life expectancy. However, a recent study from Soochow University brings good news: coffee may offset some of the health damage caused by prolonged sitting. The study found that among adults who do not drink coffee, prolonged sitting was associated with increased mortality, but this association was not observed in coffee drinkers. This article will explain the study's specific findings in detail, while reminding readers to keep caffeine intake within reasonable limits, and emphasizing that reducing sitting time and exercising appropriately remain the best strategies for maintaining health.

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…]

Ceylon black tea, as a world-renowned tea, has its place of origin and health benefits widely followed. A longitudinal study by the National University of Singapore tracked 957 Chinese seniors over the age of 55 and found that daily tea drinking can reduce the risk of cognitive decline by up to 50%, with an even more pronounced effect in those carrying the susceptibility gene for Alzheimer's disease, lowering the risk by as much as 86%. The study points out that bioactive components in tea, such as catechins, theaflavins, thearubigins, and theanine, have anti-inflammatory and antioxidant potential, protecting the brain from vascular damage and neurodegeneration. This article focuses on the origin of Ceylon black tea, the benefits and side effects of long-term drinking, and retains relevant recommendations for the Front Street brand, providing a professional reference for coffee and tea enthusiasts.

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…]

When milk tea cup sleeves at Fudan University Medical School are printed with drug instructions, when Beijing University of Chinese Medicine adds ginger, cinnamon, dried tangerine peel, red dates, and goji berries to milk tea, and when Shanghai's time-honored Chinese medicine brand Tong Han Chun Tang uses "medicine and food homology" as a selling point to launch ginseng and peach gum milk tea, the milk tea category is undergoing a transformation attempt from "junk food" to "health drink." University cafeterias, Chinese medicine shops, and time-honored brands are all crossing over into the market, trying to reshape the image of milk tea with the concept of health. At the same time, milk tea brands are also making changes on the ingredient side, with fresh fruit and fresh milk replacing non-dairy creamer as selling points. However, news about milk tea on trending searches is repeatedly linked to food safety issues, and the road to transformation is not smooth. [more…]

Luckin Coffee recently relaunched last year's hit Coconut Cold Brew, and has announced that in May it will bring back popular products such as Orange Golden Sparkling Americano in phases. However, the reformulated zero-sugar version has sparked polarized reviews among consumers—some complain it's like "waiting for a cheating scumbag to change," with a taste vastly different from what they remember, while others question the medicinal taste brought by artificial sweeteners. From packaging updates to health controversies, this round of comebacks reflects the brand's difficult balancing act between the sugar-reduction trend and faithful flavor reproduction. This article sorts through the details of the product iterations and genuine feedback from netizens, and cites a University of Southern California study on how artificial sweeteners affect appetite, to explore whether zero-sugar drinks are truly healthier.

For a long time, caffeine has often been seen as the culprit behind coffee's unhealthy reputation, leading many people to switch to decaf. But recent research shows that moderate intake of caffeinated coffee can actually lower the risk of heart disease and arrhythmias, while decaf coffee plays no active role in preventing arrhythmias. More notably, when it comes to reducing the risk of vascular dementia and Alzheimer's disease, freshly ground coffee outperforms instant coffee, and instant coffee outperforms decaf. Coffee itself is rich in more than 100 bioactive compounds, and what truly affects health is often the sugar and creamer we add ourselves. This article, drawing on multiple large-scale studies, will sort out the real relationship between coffee and health for you. [more…]

Besides waking you up, coffee may also bring unexpected benefits for muscle health. A latest study jointly conducted by research institutions in Switzerland, Singapore, the United Kingdom and other countries shows that trigonelline, a natural plant alkaloid in coffee, can boost NAD⁺ levels in the body and improve mitochondrial function, thereby helping to maintain muscle strength and slow age-related muscle degeneration. Published in a Nature sub-journal, the study offers coffee lovers a new health perspective. However, the researchers also caution that coffee is only a supplementary aid—balanced nutrition and regular exercise are fundamental to keeping muscles strong. [more…]

Recently, a "medical record card milk tea" launched by the School of Medicine at Fudan University has continued to spark heated discussion online. Its packaging design mimics prescription slips and medical record cards, printed with phrases such as "oral miracle cure" and "miraculous healing," and the straws even reproduce street signs from around the medical school, making it full of fun.

On the list of troubles faced by today's young people, hair loss probably ranks near the top. Losing handfuls of hair at a young age, and watching their hairline recede day by day, many people have tried all kinds of anti-hair-loss methods, but the results vary from person to person. Besides genetic and disease factors, eating habits may also be quietly increasing the risk of hair loss. Recently, a study published by researchers from Tsinghua University in the nutrition journal Nutrients offered a new idea for young people troubled by hair loss—quitting sugar to prevent baldness. The study surveyed 1,028 participants across 31 provinces nationwide and found a significant association between sugar-sweetened beverage intake and the risk of hair loss in men. Men who drank more than one 500-milliliter sugar-sweetened beverage per day had a 253% higher incidence of hair loss. How exactly was this study designed? Which sugar-sweetened beverages carry the highest risk? Let's take a closer look. [more…]

This article will revisit the unique features of this store, present the real reactions of customers, and sort out the possible reasons for its closure. [more…]

In recent years, zero-calorie sugar substitute products have been marketed with a health halo, becoming highly sought after by consumers who want sweetness without the calories. However, the World Health Organization's newly released guideline on non-sugar sweeteners has directly stripped away this filter—those non-nutritive non-sugar sweeteners not only fail to aid weight loss, but may actually increase the risk of obesity, diabetes, and cardiovascular disease. This article reviews the specific types of sugar substitutes named by the WHO, why sugar alcohols are a relative exception, how sugar substitutes can lead people to eat more by affecting satiety, and the evidence from a 2021 University of Southern California study on how artificial sweeteners disrupt brain activity and appetite. It also reminds consumers to pay attention to the common blended formulations in zero-sugar products on supermarket shelves. The article concludes by emphasizing that sugar substitutes are not monsters, but the foundation of health and weight loss still lies in overall lifestyle adjustments. [more…]
