每天喝咖啡，一定要知道的十个咖啡硬知识！每天喝咖啡，一定要知道的十个咖啡硬知识！

你每天下午手抖心慌还硬撑？

或者喝完咖啡反而更累更胖？

折腾半天发现这杯黑水白喝了。

我刚刷到一组2024年的新研究，整个人愣了下。

原来我们大多数人喝咖啡的方式，从时间到种类，全在踩坑。

那些说咖啡伤胃致癌的，和把咖啡当仙丹的，其实都离谱。

很多人栽在空腹灌黑咖上。

胃好的人觉得提神，胃弱的人当场反酸烧心。

很多人不知道，冷萃才是胃弱星人的救命稻草。

低温泡出来的咖啡，酸性物质少一大截，刺激性直接砍半。

别再去咖啡店点热美式折磨自己的胃黏膜了。

下午两点后还在喝？

咖啡因在体内要六个小时才代谢掉一半。

你晚上失眠真不怪压力大，是那杯拿铁在血管里蹦迪。

想睡个好觉，过了中午就得停。

速溶三合一更是重灾区。

植脂末和糖比咖啡粉还多，喝这个减肥等于吃饭配减肥药，白搭。

纯黑咖确实能提升代谢，但前提是你得受得了那个苦，而且得在运动前喝才管用。

真正让我意外的是今年的新发现。

去年有篇研究跟踪了几十万人十几年，发现每天喝三杯纯黑咖的人，比不喝的少死17%。

不是让你永生，是心脑血管确实受益。

但超过六杯反而心慌风险飙升，过犹不及。

糖尿病那边也有动静。2023年的大样本研究显示，三四杯无糖黑咖能让二型糖尿病风险降三成。

可你加两勺糖倒半杯奶，这保护效果直接归零。

为了健康喝咖啡，结果喝成糖水，图啥？

孕妇群体更得小心。

今年美国妇产科的新指南明确划了红线，每天咖啡因不能超过200毫克，大概就一到两杯。

超了和低出生体重有关，不是危言耸听。

备孕的和准妈妈们得把奶茶巧克力也算进这200毫克里。

还有帕金森和老年痴呆。

长期喝两杯以上的人，脑子退化的风险确实低一些。

浅烘豆里的绿原酸比深烘保留得多，提神成分也更多。

别迷信深度烘焙的焦香味，那是咖啡因被烤没了的安慰剂。

肠道这块也有新说法。

咖啡能让好细菌变多，降结肠癌风险。

但肠易激的人喝热咖啡会立刻跑厕所，改喝冷萃或者加点燕麦奶缓冲，舒服很多。

说到底，咖啡这玩意不是毒药也不是神药。

开封一个月的豆子已经氧化得差不多了，别舍不得扔。

浅烘或中烘，冷萃或手冲，早上或中午，纯黑无糖。

喝对了是护肝护心护脑子，喝错了就是胃酸失眠高血糖。

你的身体比你更知道哪杯该喝哪杯该倒。

Do you have trembling hands and palpitations every afternoon and still struggle?

Or is drinking coffee actually more tiring and overweight?

After struggling for a long time, I found that this cup of black water was just for nothing.

I just came across a set of new research for 2024, and I was stunned for a moment.

It turns out that the way most of us drink coffee, from time to variety, is all a trap.

Those who say coffee harms the stomach and causes cancer, and those who treat coffee as a elixir, are actually outrageous.

Many people fall for drinking black coffee on an empty stomach.

People with good stomachs feel refreshed, while those with weak stomachs experience acid reflux and heartburn on the spot.

Many people don't know that cold extraction is the life-saving straw for people with weak stomachs.

Coffee brewed at low temperatures has a significant reduction in acidic substances and half of its irritability.

Don't go to the coffee shop and order hot American style food to torture your stomach mucosa anymore.

Are you still drinking after 2pm?

Caffeine takes six hours in the body to be metabolized by half.

It's not surprising that you're under a lot of pressure at night, it's that latte bouncing in your veins.

If you want to have a good sleep, you have to stop after noon.

Instant three in one is even more severely affected.

Plant fat powder and sugar are more abundant than coffee powder, drinking this for weight loss is equivalent to taking weight loss pills with meals, it's useless.

Pure black coffee can indeed improve metabolism, but the prerequisite is that you can tolerate the pain and drink it before exercise to be effective.

What really surprised me was this year's new discovery.

Last year, a study tracked hundreds of thousands of people for over a decade and found that those who drank three cups of pure black coffee a day died 17% less than those who didn't.

It's not about making you immortal, it's the cardiovascular system that really benefits.

But after more than six cups, the risk of palpitations skyrocketed, too much is too much.

There are also some movements in diabetes. A large sample study in 2023 shows that three or four cups of sugar free black coffee can reduce the risk of type 2 diabetes by 30%.

But if you add two spoons of sugar and pour half a cup of milk, the protective effect will be reduced to zero directly.

Drinking coffee for health, but ended up drinking sugar water, what's the picture?

Pregnant women need to be more careful.

This year, the new guidelines for obstetrics and gynecology in the United States have clearly drawn a red line, stating that caffeine should not exceed 200 milligrams per day, approximately one to two cups.

Excess is related to low birth weight, not an exaggeration.

Pregnant women and expectant mothers need to include milk tea and chocolate in this 200 milligrams.

There are also Parkinson's and Alzheimer's disease.

People who drink two or more glasses over a long period of time do have a lower risk of brain degeneration.

Light baked beans retain much more chlorogenic acid and have more refreshing ingredients than deep baked beans.

Don't be superstitious about the burnt aroma of deep baking, it's a placebo for caffeine to be roasted away.

There is also a new theory regarding the gut.

Coffee can increase the number of good bacteria and reduce the risk of colon cancer.

But people with irritable intestines who drink hot coffee will immediately go to the bathroom and switch to cold brew or add some oat milk as a buffer, which is much more comfortable.

Ultimately, coffee is neither a poison nor a miracle drug.

The beans that have been in Kaifeng for a month have almost oxidized, don't be reluctant to throw them away.

Light or medium baking, cold extraction or hand wash, morning or noon, pure black without sugar.

Drinking the right drink can protect the liver, heart, and brain, while drinking the wrong drink can lead to stomach acid, insomnia, and high blood sugar.

Your body knows better than you which cup to drink and which cup to pour.
