Pu’er Coffee

 One cup wakes you up. Two cups keep you going. The bitter, aromatic taste is hard to resist. Among all the things that stimulate the brain and create mild dependence, coffee is arguably one of the healthiest. A morning cup, an afternoon cup, one more before work begins—this is everyday life for countless coffee lovers. But what many people don’t realize is that choosing the wrong coffee—or brewing it the wrong way—can quietly work against your health . Certain types of coffee can actually raise total cholesterol and LDL cholesterol levels. The hidden culprit? Unfiltered coffee. Let’s start with a quick explanation of LDL cholesterol, often referred to as “bad cholesterol.” Unlike HDL (“good cholesterol”), which helps clear cholesterol from blood vessels, LDL transports cholesterol from the liver throughout the body. When LDL levels are too high, it can penetrate blood vessel walls, become oxidized, trigger inflammation, and gradually form plaques. These plaques narrow arteries ...

 Every morning, the elevators in office buildings are filled with the rich aroma of coffee. Sleepy office workers cling to their cups of “life support.” Some get headaches if they skip a day; others rely on coffee to survive endless nights of overtime. But the warnings never stop: “Coffee hurts your stomach,” “Coffee causes insomnia,” “Too much leads to osteoporosis.” So what’s the truth? What really happens to your body when you drink coffee for years? Let’s break it down — especially for three types of people who may need to rethink their relationship with coffee. 1. The “Sensitive Stomach” Crowd Do you feel acid rising in your stomach or even a dull ache after drinking coffee? You’re not being dramatic — your stomach is sending out an SOS. Caffeine and organic acids in coffee — such as chlorogenic acid — stimulate stomach acid secretion. For most people with healthy digestion, this is tolerable and may even help digestion. But if you already have acid reflux, ulcers, or c...

 If the first thing you do in the morning is make coffee, if you always keep a latte by your side while working, and if you rely on an afternoon Americano to stay alive—does that sound like you? The aroma of coffee is truly irresistible. It not only boosts alertness but has also become an essential part of our daily lives. But what you may not know is that for some people, this dark beverage may hide certain health risks. 1. Pregnant and breastfeeding women Expectant mothers need to pay special attention. Caffeine can pass through the placenta and enter the fetus’s body, and since the baby’s metabolic system is not fully developed, it may affect fetal health. During breastfeeding, caffeine can be transferred to the baby through breast milk, potentially causing irritability and poor sleep. Many soon-to-be moms find that after giving up coffee, not only does their own sleep quality improve, but their baby becomes calmer as well. 2. People with osteoporosis Once you reach your for...

 For many office workers, surviving the day often means running on caffeine. A cup of coffee in the morning, another after lunch, and maybe one more to power through overtime. Coffee truly helps you stay alert—but for some people, overdoing it could quietly harm your health. Let’s start with a real case: A 32-year-old office worker drank at least five cups of coffee every day to stay awake for overtime. One evening, she suddenly felt her heart racing, her hands shaking, and cold sweat pouring down. She was rushed to the hospital, where doctors diagnosed her with caffeine-induced arrhythmia. The doctor warned her seriously: “If you keep drinking coffee like this, your heart won’t be able to handle it.” Coffee can be wonderful, but it’s not for everyone. Here are eight groups of people who need to watch their caffeine intake carefully. 1. People with Heart Problems Caffeine stimulates the sympathetic nervous system, which can cause faster heartbeats and higher blood pressure. If...

 Coffee can be an amazing pick-me-up — a source of energy when fatigue hits. But here’s the thing: it’s not for everyone. For some people, that comforting cup of black coffee may be quietly draining their health instead of boosting it. Let’s take a closer look — are you one of them? 1. Those with Sensitive Stomachs Have you ever felt stomach discomfort after drinking coffee? That’s because several compounds in coffee can irritate the digestive system. Both caffeine and chlorogenic acid stimulate stomach acid production, which can worsen acid reflux or heartburn. The effect is especially strong when you drink coffee on an empty stomach — a common habit for many people rushing out the door in the morning. Over time, this can damage the stomach lining and even trigger gastritis or make existing problems worse. If you often feel bloated, nauseous, or experience stomach pain after coffee, it may be time to cut back — or take a break from caffeine altogether. 2. People at High R...

 For many modern people, coffee isn’t just a trendy beverage — it’s a daily survival tool. Especially for office workers grinding through long hours, that morning cup often feels like fuel for existence. While countless studies highlight the potential health benefits of coffee — boosting alertness, reducing fatigue, lowering the risk of type 2 diabetes, and even helping prevent certain cancers — it’s not a one-size-fits-all miracle drink. A recent study from Soochow University in China added an intriguing twist: coffee might actually counteract some of the negative effects of sitting for long periods. Researchers found that people who sat for six or more hours a day and didn’t drink coffee had a 1.58 times higher mortality risk than those who sat less and drank coffee regularly. In other words, among non-coffee drinkers, the longer they sat, the higher their overall risk of death. Still, coffee isn’t for everyone. Below are nine groups of people who should think twice before ...
