Pu’er Coffee

 Here’s what happened. A while ago, while I was scrolling through short-form videos, I came across a piece of medical-related news about coffee. It said that drinking coffee made without a filtration step—such as coffee brewed with a moka pot or a French press—may raise cholesterol levels in the body, thereby increasing the risk of cardiovascular and cerebrovascular diseases. I don’t claim any authority when it comes to medical science, but this still made me curious enough to dig a little deeper and see what was really going on. So today, I’d like to talk about this topic with you. The reason behind this has to do with two natural oils found in coffee: cafestol and kahweol . Cafestol is a diterpene compound extracted from coffee beans and is structurally similar to kahweol. Research suggests that cafestol may increase cholesterol levels. Kahweol, also a natural diterpene compound from coffee beans, has been shown to have anti-inflammatory, anti-angiogenic, and anti-cancer prope...

 The moment you open your eyes in the morning, you might not even head to the bathroom first—you head straight to the kitchen for a cup of coffee. Sounds familiar, right? But standing in front of your coffee shelf, you might suddenly freeze: pour-over feels ceremonial, instant is super convenient, and drip bags strike a nice balance. But after drinking them long enough, that nagging thought pops up: Which of these is actually the worst for your health? 1. The Three Coffee Brothers — Which One Do You Pick? Let’s meet the “three brothers” of the coffee world: pour-over, instant, and drip bags. Same family, totally different personalities. Pour-over coffee is like the picky eldest brother. You need gear—dripper, kettle, fresh beans. Grind, pour, wait. The aroma is beautiful, the flavor is layered, but the process takes patience. Perfect for slow mornings. Instant coffee is the impulsive middle child. Scoop, hot water, boom—done in 3 seconds. It’s made by extracting and dryin...

 For many people, that first cup of coffee in the morning is the switch that turns the brain on. But more and more coffee lovers are noticing a frustrating change: You used to handle three or even four cups a day without breaking a sweat. Now? Half a cup and your heart is pounding, your chest feels fluttery, and you start wondering: “Is something wrong with my heart?” “Am I really just getting old?” The good news: you don’t need to panic. Coffee-induced heart flutters are usually not a sign of disease. They come from how your body interacts with caffeine. Today, let’s break it all down clearly—so you can keep enjoying your coffee with peace of mind. 1. Heart palpitations after coffee = caffeine doing its job First, let’s get one thing straight: feeling a bit jittery or noticing a faster heartbeat after drinking coffee doesn’t usually mean something is wrong. It’s simply caffeine doing what caffeine does. The main effect of caffeine is activating your sympathetic nervous s...

 The morning sun slips through the curtains, and for many people, the very first thing they do after waking up is make a cup of coffee. The rich aroma fills the air, instantly awakening the sleepy soul. But what you may not realize is — this daily ritual might be quietly harming your stomach. Think about it: after a night of rest, your stomach is completely empty. Then, suddenly, a cup of coffee rushes in. The caffeine in it directly stimulates the stomach lining, triggering an excessive secretion of stomach acid. With no food to digest, the extra acid ends up “corroding” the stomach walls themselves. Over time, this can lead to discomfort such as stomach pain, acid reflux, or heartburn. For many people, chronic gastritis actually begins with small, repeated habits like this. These Three Groups Should Be Especially Careful 1. People who already have stomach issues If you often experience stomach pain, bloating, or have been diagnosed with gastritis or ulcers, drinking coff...

 In summer, we grab an iced Americano to cut the grease; in winter, we wrap our hands around a hot latte to stay warm. It’s a daily ritual for many office workers. But when the topic #ColdCoffeeAndHotCoffeeAren’tJustAboutTemperature started trending online, people were confused: "Wait—so I’ve been drinking it wrong this whole time? No wonder iced coffee keeps me up at night and hot coffee hurts my stomach!" The truth is, the difference between hot and cold coffee goes far beyond “temperature.” From how it’s brewed to how your body reacts to it, there’s a lot going on behind each sip. Let’s break it all down — so next time you order, you won’t regret your choice. A lot of people assume that iced coffee is just hot coffee with ice tossed in . Not quite. It’s like reheating a cup that’s gone cold — it’ll never taste like fresh hot coffee again. The real difference lies in how the coffee is extracted — the temperature and time used to pull flavor from the beans. Cold brew ...
