Symptoms of a Coffee Allergy

Symptoms of a Coffee Allergy

Many people drink a cup of coffee in the morning to help them wake up. Caffeine, a natural drug contained in coffee, stimulates the central nervous system. But what effect can caffeine have on the body if a person is allergic to it? This article explores the symptoms of coffee a allergy, what causes it, and how it may be treated.

Caffeine is found in a range of plants including coffee beans, tea leaves, and cacao pods. It is consumed all over the world in coffee, tea, and chocolate. Approximately 90 percent of people in North America consume caffeine every day. While caffeine is safe for most people, some people have a caffeine intolerance or allergy.

Caffeine and its effects

Caffeine is a stimulant that makes people feel more awake and focused. However, it may cause a number of symptoms, including an allergic reaction in some people.

Drinking coffee and other caffeinated drinks is a cultural norm in the United States and many other countries.

Caffeine is a natural stimulant that affects the brain and central nervous system, making people feel more alert and focused. Many drink coffee during their working day, as they believe it makes them more productive.

Most people can safely drink up to 400 milligrams (mg) of caffeine a day, the equivalent of around four cups. However, some people are sensitive to caffeine and experience the following when they consume it:

People who experience these symptoms may have a non-allergic food intolerance to caffeine.

Intolerance is different from having a caffeine allergy. Caffeine allergies are rare, and the symptoms of a caffeine allergy are more serious than those of an intolerance.

Symptoms of coffee a allergy

The symptoms of a coffee allergy include:

  • hives, an itchy rash made up of many red bumps
  • swelling of the lips and tongue
  • itchy mouth, lips, and tongue

If a person has a caffeine allergy, these symptoms may occur within an hour of consuming caffeine.

Some people may experience a severe allergic reaction in response to caffeine called an anaphylactic shock, as this 2015 study reports. It is important to note that this is very rare.

The symptoms of an anaphylactic shock may include:

  • severe facial swelling, including eyes, lips, face, and tongue
  • trouble breathing due to facial swelling
  • trouble speaking
  • wheezing
  • coughing
  • nausea, abdominal pain, or vomiting
  • rapid heartbeat
  • dizziness

Symptoms of a coffee allergy and intolerance

While some people who experience symptoms when drinking caffeine are allergic to it, others will have a non-allergic intolerance.

Caffeine affects different people in different ways. The effects that caffeine has on the body of someone who is allergic to it are not the same as for someone who is caffeine intolerant.

When a person consumes caffeine, it is absorbed into their bloodstream from their gut. It can then affect how different organs work.

In the brain, caffeine blocks the effects of chemical messengers that normally make a person sleepy. It may also increase levels of adrenaline in the blood, which makes the brain and body more alert.

For people who have a non-allergic caffeine intolerance, the rush of adrenaline from caffeine may cause them to experience symptoms.

In contrast, a person with a caffeine allergy has symptoms that are caused by an allergic reaction.

Treatments for caffeine allergy

If a person experiences an allergic reaction after consuming caffeine, then over-the-counter antihistamines may help reduce any itching, swelling, or hives.

In very rare cases, a caffeine allergy may cause anaphylactic shock. This can be treated with an injection of epinephrine. People with severe allergies often carry a special pen to administer this.

If a person is showing signs of an anaphylactic shock, contact emergency services immediately.

Caffeine in Tea Vs Coffee

Caffeine in Tea vs Coffee is unparalleled.

It’s found in over 60 plant species and enjoyed across the globe, especially in coffee, chocolate, and tea.

The caffeine content in a beverage varies depending on the ingredients and how the drink is prepared.

While caffeine is considered safe, drinking too much may raise some concerns.

This article compares the caffeine contents of a variety of teas and coffees and explores which drink you should choose.

Why is caffeine a concern?

An estimated 80% of the world’s population enjoys a caffeinated product daily.

Both the U.S. Department of Agriculture (USDA) and European Food Safety Authority (EFSA) define a safe caffeine intake and caffeine in tea vs coffee is up to 400 mg per day, 200 mg per single dose, or 1.4 mg per pound (3 mg per kg) of body weight (1Trusted Source2Trusted Source3).

Due to its stimulating effects, caffeine has been linked to health benefits like enhanced alertness, improved athletic performance, elevated mood, and increased metabolism (4Trusted Source5Trusted Source6Trusted Source7Trusted Source).

That said, consuming high amounts — such as single doses over 500 mg — may raise some concerns (2Trusted Source3).

In large doses, caffeine has been associated with anxiety, restlessness, and difficulty sleeping. In addition, some studies suggest that drinking it regularly, even in moderate amounts, can cause chronic headaches and migraines (8Trusted Source9Trusted Source10Trusted Source).

Furthermore, caffeine is considered mildly addictive, and some people may be more susceptible to developing a dependence (9Trusted Source).


Caffeine content varies by beverage type and preparation

The amount of caffeine in tea or coffee can vary significantly depending on the origin, type, and preparation of the drink (11Trusted Source).

Tea leaves contain 3.5% caffeine, while coffee beans have 1.1–2.2%. However, the coffee brewing process uses hotter water, which extracts more of the caffeine from the beans. Typically, you also use more coffee beans than you’d use tea leaves for a drink (12).

Therefore, 1 cup (237 ml) of brewed coffee generally has more caffeine than a cup of tea.

Tea varieties

Black, green, and white teas are prepared from leaves of the same plant, Camellia sinensis. What sets them apart is the time of harvest and level of oxidation of the leaves (4Trusted Source).

Black tea leaves are oxidized, while white and green tea leaves are not. This gives black tea a characteristic bold and sharp flavor and increases the extent to which caffeine from the leaves infuses hot water (4Trusted Source).

An average cup (237 ml) of black tea packs 47 mg of caffeine but can contain as much as 90 mg. For comparison, green teas contain 20–45 mg, while white teas deliver 6–60 mg per cup (237 ml) (1213Trusted Source14).

Matcha green tea is another high-caffeine tea. It usually comes in powdered form and packs 35 mg of caffeine per half-teaspoon (1-gram) serving (4Trusted Source).

Similarly, yerba mate, a tea traditionally enjoyed in South America that’s made by steeping the twigs and leaves of the Ilex paraguariensis plant, usually contains 85 mg of caffeine per cup (237 ml) (12).

It’s also important to note that although herbal teas are marketed as caffeine-free, one mug of these may still deliver up to 12 mg of caffeine. That said, this is considered a negligible amount (4Trusted Source).

Tea preparation

The preparation method greatly impacts the caffeine content of tea. Teas that steep for longer and in hotter water tend to produce a more potent cup (4Trusted Source).

For example, a mug of Tazo Earl Grey contains 40 mg of caffeine after 1 minute of steeping in 6 ounces (177 ml) of water heated to 194–203°F (90–95°C). This amount rises to 59 mg after 3 minutes (4Trusted Source).

For comparison, Stash Green Tea has 16 mg of caffeine after 1 minute of steeping under the same conditions. After 3 minutes of steeping, this more than doubles to 36 mg (4Trusted Source).

Coffee varieties

An average 8-ounce (237-ml) cup of coffee contains 95 mg of caffeine (2Trusted Source).

It’s a common belief that coffee made from dark-roasted beans has more caffeine than coffee from light-roasted beans. However, since caffeine isn’t affected much by roasting, this may not be the case (15).

That said, since dark roast coffees are less dense than light roast ones, you may use greater amounts of beans or grounds when brewing this type, yielding more caffeine per cup (15).

Espresso is a more concentrated source of caffeine (1516Trusted Source).

For example, a “single” espresso from Starbucks has about 58 mg of caffeine per 1-ounce (30-ml) shot. Most specialty coffee drinks, such as lattes and cappuccinos, are made with a double shot of espresso, containing 116 mg of caffeine (16Trusted Source).

Among decaffeinated beverages and caffeine in tea vs coffee, decaf espresso tends to have the most caffeine with 3–16 mg per 16-ounce (473-ml) serving, whereas decaf coffee typically provides less than 3 mg per 8-ounce (237-ml) cup. Decaffeinated teas fall in between these two types of coffee (4Trusted Source16Trusted Source17).
