6 Foods You Should Never Eat with 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. Alcoholic Beverages
Both caffeine and alcohol affect the nervous system. Some people believe coffee can “sobering up” after drinking, but caffeine only masks the symptoms temporarily—it doesn’t speed up alcohol metabolism. In fact, it can make you overestimate your alertness, increasing the risk of drinking too much. Consuming coffee and alcohol together also puts extra strain on your heart and liver, which may pose long-term health risks.

3. High-Calcium Foods
Dairy products like milk and cheese are common coffee companions, but heavy coffee consumption can interfere with calcium absorption. Caffeine acts as a diuretic, increasing calcium excretion through urine, while tannins bind to calcium and reduce its bioavailability. If you’re focusing on calcium intake or bone health, it’s best to separate the timing of coffee and high-calcium foods.

4. Seafood
Seafood is rich in high-quality protein and minerals like zinc, making it a favorite for many. However, tannins in coffee can bind with proteins in seafood, forming compounds that are hard to digest. This not only reduces nutrient absorption but may also cause stomach discomfort. If you’re enjoying a seafood meal, wait a while after eating before sipping your coffee.

5. Spicy Foods
Chili peppers, mustard, and other spicy foods naturally stimulate the stomach lining, while caffeine promotes gastric acid secretion. The combination can irritate your stomach even more. Regularly pairing spicy food with coffee may lead to discomfort and, over time, could increase the risk of gastritis. If you have a sensitive stomach, this is a combination to avoid.

6. Certain Medications
Many people take medications with coffee, but this habit can be risky. Caffeine can interact with certain drugs, such as reducing the absorption of antibiotics or intensifying the effects of stimulants. The safest option is always to take medication with plain water.

Knowing which foods don’t pair well with coffee can help you enjoy your cup even more. A simple rule of thumb: drink coffee on its own, at least an hour apart from meals. This not only avoids nutrient conflicts but also lets you fully savor the rich, unique flavor of your coffee.

Guangxi Coffee Explained: China’s Emerging High-Altitude Coffee Origin Beyond Yunnan

图片
 Not long ago, while scrolling through Weibo, I came across a post saying that Guangxi has started growing its own coffee . That immediately caught my attention and genuinely surprised me. Curious, I decided to dig deeper and share what I found with you. From a coffee perspective, China is actually a rather unique country. It has a complete coffee supply chain —from cultivation and roasting to distribution and consumption. China is both a coffee-producing nation and a coffee-consuming one. When people talk about Chinese coffee, Yunnan naturally comes to mind as the most well-known producing region. Over the past few years, we’ve all witnessed the remarkable transformation of Yunnan coffee. It has moved from being primarily bulk-purchased for instant coffee to embracing a mature specialty coffee path. Today, even traditionally processed Yunnan Catimor can offer a clean and pleasant cup profile, and varieties like Yunnan Geisha have also emerged, bringing greater diversity. These...

Why Water Quality Matters in Pour-Over Coffee (Alkalinity, Hardness & Flavor Explained)

图片
 The coffee we drink is, at its core, water that has dissolved the flavorful compounds inside coffee grounds. In fact, more than 98% of a cup of pour-over coffee is water. We spend so much time chasing the best origins and growing regions, the most suitable processing methods, the perfect roast profiles, and the most precise brewing techniques—yet all of these efforts ultimately rely on water to carry the coffee’s flavor. If we overlook the foundational role of water, everything else can easily fall apart. **No.1 Water Plays Two Core Roles in Coffee Brewing: Extraction and Flavor** Water is responsible for extracting soluble flavor compounds from coffee grounds, and it also makes up the body of the final beverage itself. The chemical composition of the water directly influences what ends up in your cup. **No.2 The Soluble Compounds in Water: Alkalinity and Hardness** Water contains both negatively charged ions and positively charged ions. The concentration of negatively ...

Would You Drink Coffee Made from Food Waste? The Rise of Beanless Coffee Explained

图片
 Every single second, the world consumes about 26,000 cups of coffee . On Shanghai’s Huaihai Road alone—less than two kilometers long—you can find nearly 50 cafés , each with its own style. Coffee has long since become a nationwide obsession. Enthusiasts eagerly debate bean origins, processing methods, and flavor notes, yet few stop to ask a deeper question: What hidden burden does this beloved drink place on the planet? From a food-industry carbon-emissions perspective, coffee ranks just behind beef, lamb, cheese, and chocolate . Data shows that producing a single cup of coffee consumes roughly 140 liters of water , while growing and processing one kilogram of coffee beans generates about 17 kilograms of CO₂ . Viewed through the lens of Western environmental narratives, this kind of data practically screams: ban it . How could such an “unethical” product escape scrutiny in one of the world’s environmental flag-bearers—the UK? British research has already sounded the alarm: by 20...
