Is Instant Coffee Bad For You? A Comprehensive Guide

Instant coffee has become a popular beverage choice for many individuals due to its convenience and quick preparation time. However, there has been debate about whether or not it is a healthy choice.

In this article, we will explore the ingredients of instant coffee, the potential health benefits, as well as any potential negative effects. We will also examine what experts have to say about the consumption of instant coffee and ultimately determine whether or not it is bad for you.

What is Instant Coffee?

Instant coffee, also known as soluble coffee, is a type of coffee that is made from brewed coffee beans which have been dried and processed into a powder or granules. 

When mixed with hot water, the powder or granules dissolve, creating a cup of coffee. Instant coffee is often used as a quick and convenient alternative to brewed coffee.

Nutrition Facts of Instant Coffee

Instant coffee is a low-calorie beverage that provides a burst of energy due to its caffeine content. The nutritional facts of instant coffee can vary depending on the brand and serving size, but typically include:

  • Calories: 1-3 per serving
  • Protein: 0g
  • Fat: 0g
  • Carbohydrates: 0-1g

The main ingredient in instant coffee is, of course, coffee beans. However, during the production process, the beans undergo several treatments that can alter their nutritional content. 

Some brands may add other ingredients such as sugar, creamer, or flavorings to their instant coffee products, which can increase their calorie count and alter their nutritional profile. It is important to read the labels carefully and be aware of any added ingredients.

Pros and Cons

Here are some pros and cons of instant coffee:


  • Convenience. Instant coffee is very easy to make and can be prepared quickly, making it a popular choice for people who are always on-the-go.
  • Longer shelf life. Instant coffee can last for months or even years, making it more convenient than regular coffee that needs to be used within a few weeks.
  • Lower cost. Instant coffee is generally less expensive than regular coffee, making it an affordable choice for people on a tight budget.


  • Less flavor. Instant coffee often has a less complex flavor profile compared to regular coffee due to the manufacturing process.
  • May contain additives. Some instant coffee brands may contain additives such as sugar or artificial flavorings, which can be unhealthy if consumed in excess.
  • May not be as fresh. Since instant coffee is made from pre-brewed coffee that has been dehydrated, it may not be as fresh as regular coffee that is brewed from fresh beans.

Overall, instant coffee can be a convenient and affordable option for those who need their coffee fix quickly, but may not offer the same quality and flavor as regular coffee.

Health Benefits of Instant Coffee

Instant coffee has been shown to have several potential health benefits when consumed in moderation. Here are a few:

  1. May lower risk of type 2 diabetes: According to a study individuals who drank 3-4 cups of coffee per day had a lower risk of developing type 2 diabetes compared to those who didn’t drink coffee.
  2. May protect against liver disease. A study published in 2016 found that coffee consumption was associated with a lower risk of developing liver disease, including liver cancer and cirrhosis.
  3. May improve cognitive function. According to a 2020 study, consuming caffeine from coffee or other sources may help improve cognitive function, particularly in older adults.
  4. May reduce risk of depression. A 2018 study found that individuals who consumed 3-4 cups of coffee per day had a lower risk of developing depression compared to those who consumed less or no coffee.

It’s worth noting that these studies show a correlation between coffee consumption and potential health benefits, and more research is needed to fully understand the mechanisms behind these benefits

Scientific Studies on Instant Coffee

Here are 5 studies on the health effects of instant coffee:

  1. A study published in the European Journal of Epidemiology found that regular consumption of instant coffee was associated with a lower risk of liver cancer in both men and women.
  2. A review of studies published in the American Journal of Clinical Nutrition found that instant coffee consumption was associated with a lower risk of type 2 diabetes
  3. A study published in the Journal of Nutrition found that instant coffee consumption was associated with a reduced risk of cardiovascular disease
  4. A study published in the International Journal of Cancer found that regular consumption of instant coffee was associated with a lower risk of colorectal cancer.
  5. A study published in the Journal of Alzheimer’s Disease found that caffeine consumption, including from instant coffee, was associated with a lower risk of cognitive decline in older adults

It’s important to note that while these studies suggest potential health benefits of instant coffee, more research is needed to confirm these findings and to determine the optimal amount of consumption for these benefits.

What do Health experts say about Instant Coffee?

There is limited research specifically on the health effects of instant coffee, but many health experts agree that it can have some potential benefits. 

Registered dietitian and nutritionist, Lauren Manaker, says that instant coffee can be a good source of antioxidants and may have benefits for liver health.

In an interview with Healthline, Manaker stated, “Instant coffee has slightly less antioxidants than freshly brewed coffee, but it still contains some. 

Additionally, studies have linked regular coffee consumption to a lower risk of liver disease and cancer, and it’s thought that instant coffee could have similar effects.”

However, it’s important to note that instant coffee may contain added sugars or artificial flavors, which can be detrimental to health if consumed in excess. It’s also important to pay attention to the caffeine content in instant coffee and consume it in moderation.

Who Should Avoid Instant Coffee?

While instant coffee is generally safe for most people to consume, there are some individuals who should avoid it or limit their consumption due to certain health conditions. These include:

  1. People with acid reflux or GERD. Instant coffee is more acidic than regular coffee, which can aggravate symptoms of acid reflux or gastroesophageal reflux disease (GERD) in some individuals. It is recommended that those with these conditions limit or avoid consumption of instant coffee.
  2. People with anxiety or sleep disorders. Instant coffee contains caffeine, which can exacerbate symptoms of anxiety and interfere with sleep in some individuals. Those with anxiety or sleep disorders may want to limit their intake of instant coffee or avoid it altogether.
  3. Pregnant women. While moderate caffeine intake is generally considered safe during pregnancy, high caffeine intake (more than 200-300 mg per day) has been associated with an increased risk of miscarriage, low birth weight, and preterm birth. It is recommended that pregnant women limit their caffeine intake, including instant coffee.

Alternatives to Instant Coffee

Here are three alternatives to instant coffee:

  1. Pour-over coffee: This method involves pouring hot water over coffee grounds that have been placed in a filter. It allows for more control over the brewing process and can result in a better-tasting cup of coffee.
  2. French press coffee: French press coffee is made by steeping coffee grounds in hot water and then pressing them through a mesh filter. This method allows for a full-bodied cup of coffee and can be a good alternative for those who prefer a stronger taste.
  3. Cold brew coffee: Cold brew coffee involves steeping coffee grounds in cold water for an extended period of time, usually 12-24 hours. This method produces a smoother and less acidic cup of coffee, making it a popular alternative for those who experience stomach discomfort after drinking regular coffee.

Conclusion: Is Instant Coffee bad for you?

Like most foods and drinks, the answer to whether instant coffee is bad for you or not is not black and white.

While it has some health benefits, such as reducing the risk of certain diseases and improving brain function, it also has some downsides, such as potential exposure to acrylamide and caffeine-related side effects.

It’s important to consume instant coffee in moderation, especially if you’re pregnant, have certain health conditions, or are sensitive to caffeine. As with anything, it’s always a good idea to consult with your healthcare provider to determine what’s best for your individual health.
