Is Coffee High In Copper? (The Truth)


Your body needs copper in trace amounts to maintain good health. Copper is used to form red blood cells, bone, connective tissue, and some essential enzymes. Copper is also involved in cholesterol processing, immune system function, growth, and development of babies in the womb.

Though only in trace amounts, it is an essential mineral, which means you must obtain it through your diet because your body produces it on its own.

Copper is present in 1% of a single-serving cup of regular coffee. But I know you’re still curious about how much copper you consume with each cup of coffee. Here’s everything I discovered for you.

Does Coffee Interfere With Copper Absorption?

Adults should consume 900 mcg of copper per day. If you’re pregnant or breastfeeding, however, you should get slightly more, 1 mg or 1.3 mg daily.

Caffeine may interfere with the absorption of manganese, zinc, and copper. It also increases magnesium, potassium, sodium, and phosphate mineral excretion. Caffeine may also interfere with vitamin A action, according to research. Tea and coffee frequently contain caffeine.

Is Coffee Copper-Rich?

No, coffee contains only trace amounts of copper. The concentration of copper, on the other hand, may vary depending on the type of coffee. But, thankfully, none of them contain enough copper to be toxic.

The caffeine in coffee helps to reduce copper toxicity in the body. Copper-binding ligands in the drink are responsible for removing traces of copper toxicity from the body.

What Causes An Increase In Copper Levels In The Body?

Copper levels in the blood can be raised by pregnancy, birth control pills, infection, inflammation, and stress. Corticosteroids and corticotropin can lower your copper levels.

Here’s a video that explains the effects of copper on the human body:

How Much Is Copper in Coffee?

Coffee comes in a variety of varieties with nearly identical copper levels. 100g of coffee, on the other hand, contains about 0.05 mg of copper. The most copper we can find in 240g of brewed coffee is 0.1 mg (6%).

What Are The Most Important Health Advantages Of Drinking Coffee?

Other than boosting energy, your beverage has other advantages.

You Could Live A Longer Life

Drinkers of coffee are less likely to pass away from some of the leading causes of death in women, including stroke, diabetes, and kidney disease.

Glucose (or sugar) is processed by your body more quickly. Studies show that those who consume more coffee have a lower risk of type 2 diabetes. You are less likely to experience heart failure. One to two cups of coffee daily could help stop heart failure.

Your DNA Will Be More Powerful.

Dark roast coffee reduces DNA strand breakage, which happens naturally, but if your cells are not repaired, it could cause cancer or tumors.

You will have a significantly lower risk of getting colon cancer. Out of every 23 women, one will develop colon cancer. However, decaf or regular coffee drinkers were found to have a 26% lower risk of developing colorectal cancer.

Women make up almost two-thirds of Alzheimer’s patients in the United States. Two cups of coffee, however, might provide much protection against the condition’s onset, thanks to their caffeine content. Researchers discovered that women aged 65 had a lower risk of dementia if they drank two to three cups of coffee daily.

How Can You Naturally Lower Copper Levels?

You can reduce your copper levels by achieving nutritional balance in your diet. However, it is strongly advised to consult a physician for better diet recommendations. If you are a vegetarian, you may consume protein from foods high in copper levels.

Nuts, lamb, pork, salmon, vegetable juice cocktails, avocado, dried peas, sweet potatoes, white germ, and barley are all recommended for high copper levels.

If your copper level is not too high, you can consume cream, butter, margarine, rice, eggs, beef, and coffee.

What Time of Day Should You Drink Coffee?

Tea and coffee frequently contain caffeine.

When your stress hormone cortisol is at its lowest, this is the best time to drink coffee. That is, it is usually a few hours after you awaken. To be precise, early afternoon or mid-morning.

According to recent research, cortisol hormone levels are highest in two-time slots. The first time slot is 8 a.m. to 1 p.m.and the second time slot is 5:30 p.m. to 6:30 p.m. As a result, in the rest of the free slot between the two, we can finally appreciate the energizing effects of coffee.

It is also suggested that one experiment with drinking coffee at various times to determine which time is best for them. It’s usually a rule of thumb: “the closer you are to consumption, the more alert and focused you will feel.” Caffeinated drinks, on the other hand, should be avoided after 2:00 p.m. The worst times to drink coffee are before bed or after dinner.

Copper-Rich Foods

Here are some foods which are high in copper;


Oysters are a type of shellfish that is frequently considered a delicacy. Depending on your preferences, they can be served cooked or raw.

This seafood is low in calories while high in many essential nutrients such as zinc, selenium, and vitamin B12. Furthermore, oysters are a good source of copper, with 7.6 mg per 3.5 ounces (100 grams) or 844% of the RDI.

Because of their high cholesterol content, oysters and other shellfish may cause concern. Unless you have a genetic condition, dietary cholesterol found in foods like oysters is unlikely to significantly raise your blood cholesterol levels.

It should be noted that a high zinc intake can interfere with copper absorption, and because oysters contain 154mg of zinc per 100g. Also, raw oysters can cause food poisoning, in people with compromised immune systems.

Potassium244 mg6%

Nuts and Seeds

Small but mighty nutritional powerhouses, nuts, and seeds. They are a great source of fiber, protein, good fats, and a wide range of other nutrients.

Even though the nutrients in nuts and seeds vary, many have high copper content. For instance, one ounce (28 grams) of almond flour or cashews contains 33% and 67% of the RDI.

Furthermore, a tablespoon (9 grams) of sesame seeds contains 44% of the RDI. Nuts and seeds can be eaten as a snack, atop a salad, or baked into bread or casserole.

Dark Chocolate

Dark chocolate contains more cocoa solids than regular chocolate and less milk and sugar.

Dark chocolate contains antioxidants, fiber, and a variety of nutrients. For instance, a 3.5-ounce (100-gram) dark chocolate bar has 11 grams of fiber, 98% of the recommended daily intake of manganese, and 67% of the recommended daily intake of iron.

The same bar also has a whopping 200% RDI for copper. In addition, consuming dark chocolate as part of a healthy diet has been connected to improvements in several risk factors for heart disease. However, avoid overeating dark chocolate. It’s still a high-calorie food high in fat and possibly sugar.

Final Thoughts

  • Copper, essential for your health, can be found in various foods, from meat to vegetables.
  • Oysters, nuts, seeds, shitake mushrooms, lobster, liver, leafy greens, and dark chocolate are all excellent sources. Include a variety of these sources in your diet to avoid deficiency.
  • Coffee is the ideal combination of flavor and health benefits.
  • It has a low copper content, which aids in the removal of copper toxicity from the body. Not only that, but if consumed in moderation, the beverage can help reduce the risk of many life-threatening diseases.
  • However, we must remember that excessive coffee consumption can result in stomach upset, nervousness, insomnia, decreased heartbeat, and other adverse effects.
