Pu’er Coffee

 According to a report by Russia’s RT, a long-term study spanning more than a decade and tracking thousands of older women has revealed a notable link between everyday beverages—tea and coffee—and bone health. The findings suggest that these common drinks may significantly influence bone mineral density and fracture risk. The study was published in the journal Nutrients . The research indicates that for women aged 65 and older, regular tea consumption may help maintain relatively higher bone density, while excessive coffee intake could serve as a warning sign for bone loss. This discovery carries important implications for osteoporosis prevention. After all, one in three women over the age of 50 suffers from osteoporosis, leading to millions of fractures worldwide each year. In the past, scientific opinions on the relationship between tea, coffee, and bone health have been mixed. This new study, however, stands out for its larger scale and longer follow-up period, involving nearly...

 We often hear that “a cup of coffee a day keeps the doctor away.” Indeed, moderate coffee consumption can boost alertness and is rich in antioxidants. But just like even the best ingredients aren’t suitable for everyone, coffee is not a “universal drink” that fits all. So which friends need to push that coffee cup a bit farther away? Let’s take a look. ♥ Friends with sensitive stomachs should be careful Some friends feel as if a rock concert has erupted in their stomach after drinking coffee, churning and rumbling nonstop. This is not a coincidence. The caffeine and various organic acids in coffee stimulate stomach acid secretion. For people with healthy gastric mucosa, this may not be a big issue. But if your digestive system is already sensitive, or you have conditions like acid reflux or gastric ulcers, this surge of “acidity” may worsen your discomfort. Studies have found that coffee can indeed relax the muscle connecting the esophagus and stomach, making stomach acid more...

 For many people, coffee has become a non-negotiable “life support elixir” in daily life. But have you ever wondered—if you drink it every day for an entire month, what exactly starts happening quietly inside your body? 1. Your Mental State In the beginning, drinking coffee every day might make you feel incredibly sharp, with your productivity shooting through the roof. Caffeine blocks certain chemicals in the brain that make you feel tired, essentially giving your neurons an “emergency recharge.” But after 30 days, your body begins adapting to this external boost. What used to keep you energized for four hours may only last two, and you might find your eyes glazing over again. It’s not that coffee has “stopped working”—it’s your nervous system recalibrating to restore balance. 2. Your Digestive System Many people experience this: shortly after finishing a cup of coffee, they feel a strong urge to run to the bathroom. Coffee does stimulate gastrointestinal movement, almost li...

 Today, friends, let’s talk about a “daily essential” — coffee. This little cup of “life-saving energy” that accompanies us every day — is it a health companion or a slow poison? Today, let’s cut through the fog and uncover some truths you might not know about coffee. 1. The secret behind why it makes you instantly energized Why do you feel “powered on” the moment you drink coffee? The credit goes to its main star — caffeine. Once it enters your body, it plays the role of an “impostor,” taking the place of adenosine, the molecule responsible for telling your brain “go to sleep.” Simply put, you’re tired, your brain is about to receive a “fatigue signal,” but caffeine sits on the receptor and blocks the entrance, refusing to let the signal in. As a result, your brain doesn’t receive the message, you no longer feel sleepy, and it feels like you can finish a full annual report in one go. Tip: This “deception” works well, but don’t drink coffee too late. Otherwise, once the blo...

 You chug a big cup of coffee in the morning, but still feel half-asleep. In the afternoon, you grab another cup hoping to power through work—yet somehow, your energy drops even lower. If that sounds familiar, the problem might not be the coffee itself… it might be the way you’re drinking it. Today, let’s talk about three common coffee mistakes that secretly drain your energy instead of boosting it. I’ve made all of these mistakes myself—so consider this your shortcut to staying alert without crashing. ☕ 1. Coffee + Sugar: Double the Pleasure or Double the Burnout? Many people add sugar or creamer to make their coffee taste smoother. But that sweetness can quietly sabotage the energizing effect of caffeine. Here’s why: when you consume a lot of sugar, your body releases insulin to bring down your blood sugar. That quick spike and crash can make you feel even more tired. The result? Caffeine’s boost gets canceled out by the drowsiness that follows a sugar crash. One of my ...

 “Every time I drink coffee, I have to run to the bathroom within half an hour—it’s like my body has an alarm clock.” “I drink two cups of coffee every day, but I often feel bloated and constipated. Sometimes I even wonder if I should just give up coffee.” On October 16, the hashtag “The first batch of coffee lovers has fallen victim” started trending online. Netizens shared their very different gut reactions to coffee—some experience diarrhea, while others get constipated. Caffeine’s Dual Effect: It Can Both Relieve and Cause Constipation Why can the same cup of coffee produce two completely opposite effects? According to Cui Jun, Chief Dietitian at Beijing Electric Power Hospital, coffee’s impact on digestion is the result of multiple factors—mainly caffeine stimulation and acidic compounds. Caffeine stimulates stomach acid secretion and speeds up intestinal movement. A single intake of 100 mg of caffeine (roughly one espresso) can increase intestinal motility by nearly 3...
