Pu’er Coffee

 For many people, a rich, aromatic cup of coffee is an essential part of starting the day. Coffee certainly brings pleasure to your taste buds, but you might not realize that some foods can interfere with its benefits—or even put extra stress on your body—when consumed at the same time. Today, let’s take a look at six foods you should avoid pairing with coffee. 1. Black Fungus (Wood Ear Mushrooms) Black fungus is a popular health food, rich in iron and often referred to as “meat for vegetarians.” However, drinking coffee while eating black fungus can reduce iron absorption. The tannins in coffee bind with iron to form insoluble compounds, making it harder for your body to absorb this essential nutrient. For those with anemia or anyone needing extra iron, this is not ideal. It’s best to wait at least 2–3 hours after eating black fungus before drinking coffee. 2.

It’s the most widely consumed psychoactive substance in the world, with about 90% of adults taking it in one form or another. Caffeine can boost alertness, but it may also bring health risks. So how do we use this “double-edged sword” wisely? Let’s take a scientific look. What Exactly Is Caffeine? Caffeine is a natural alkaloid, chemically known as 1,3,7-trimethylxanthine , and it appears in over 60 plants including coffee beans, tea leaves, cocoa beans, and guarana berries. In nature, caffeine is a plant’s “secret weapon.” It can paralyze leaf-eating pests, protecting the plant, while its presence in nectar helps attract pollinator...

  Coffee is originally from Ethiopia, with its use documented only in the 15th century. It is said that Sufi monks in Yemen were the first to drink coffee, which helped them stay awake during their night prayers.   In the early 15th century, coffee spread to Mecca and subsequently throughout the Middle East. Travelers later brought coffee to Europe. In the early 17th century, some Catholics suspected coffee was the devil's drink and urged Pope Clement VIII to ban it. However, the Pope tasted the drink himself and, to their surprise, gave it his blessing. Coffee then gradually became popular in Europe.   In his book, *The Travels of Four Englishmen and a Preacher into Africa, Asia, Troy, Bythinia, Thracia, and to the Blacke Sea* (1612), William Biddulph described his first impression of tasting coffee in Turkey: "The most common drink is one called Coffa, a black drink made from a paste called Coaua, which resembles peas. The preparation involves grinding the beans and boi...
