Grounds for Indigestion? The Risks and Rewards of Eating Coffee Grounds


Last Updated:

Who would have thought that coffee grounds, the leftover residue from your morning cup of coffee, could be edible? It may sound strange, but eating coffee grounds is actually a thing.

While some people may cringe at the thought of munching on coffee grounds, others are curious about whether or not it’s safe to do so.

Can you eat coffee grounds

So, can you eat coffee grounds? The short answer is yes, but there are some important things to keep in mind which are detailed below.

Can You Eat Coffee Grounds?

Overall, eating coffee grounds is safe, but it’s important to consume them in moderation.

According to Healthline coffee beans and grounds are safe to eat. In fact, they are considered to be a rich source of antioxidants, which have been shown to reduce the risk of cancer.

You can of course make them more palatable to eat than eating them on their own by adding them to other foods, as outlined below.

Why Would Anyone Want to Eat Coffee Grounds?

While it may seem strange to some (me included actually), there are several reasons why someone might want to eat coffee grounds. Here are a few:

  • Health Benefits: Coffee grounds are a rich source of antioxidants, which have been shown to reduce the risk of cancer. They also contain dietary fiber, which can help regulate digestion and prevent constipation.
  • Energy Boost: Coffee grounds contain caffeine, which is a stimulant that can help increase energy levels and improve mental alertness.
  • Weight Loss: Some studies have suggested that consuming small amounts of coffee grounds can help with weight loss by suppressing appetite and increasing metabolism.

Potential Health Benefits of Eating Coffee Grounds


Coffee grounds are high in antioxidants, which are compounds that help protect the body from damage caused by free radicals.

Free radicals are unstable molecules that can cause oxidative stress, which has been linked to a range of health problems, including cancer, heart disease, and Alzheimer’s disease.

Antioxidants help neutralize free radicals, reducing the risk of these health problems.


Coffee grounds are also a good source of dietary fiber, which is important for maintaining digestive health. Fiber helps regulate bowel movements, preventing constipation and other digestive problems.

It also helps lower cholesterol levels and control blood sugar levels, reducing the risk of heart disease and diabetes.

Energy Boost

Consuming coffee grounds can also provide an energy boost. Coffee contains caffeine, which is a stimulant that can help improve mental alertness and physical performance.

Eating coffee grounds can provide a more sustained release of caffeine compared to drinking coffee, as the caffeine is released more slowly into the bloodstream.

Risks: Is Eating Coffee Grounds Bad for You?

It’s essential to ensure that the coffee beans used to make the coffee grounds are organic and free from chemicals and pesticides.

Digestive Issues

Consuming coffee grounds can lead to various digestive issues, including nausea, heartburn, and abdominal pain. The high caffeine content in coffee can also increase acid production in the stomach, leading to acid reflux and other discomforts.

Additionally, coffee grounds can cause dehydration as they absorb water from the body. This can lead to constipation and other gastrointestinal problems.


While coffee grounds are generally safe to eat, not all coffee is safe to consume. Non-organic coffee beans may contain harmful chemicals and pesticides that can be harmful to the body when ingested.

Coffee grounds can potentially contain trace amounts of heavy metals, such as lead and cadmium, which can be harmful if consumed in large amounts.


Another potential risk of eating coffee grounds is the presence of oils that can raise cholesterol levels.

Two diterpenes called cafestol and kahweol are found in coffee beans, and they can elevate cholesterol levels when consumed. However, the amount of these compounds in coffee grounds is relatively low, so the risk is minimal.

Choking Hazard

Coffee grounds can also pose a choking hazard, especially when consumed in large quantities or when ingested by young children or elderly individuals with impaired swallowing abilities.

Ways to Eat Coffee Grounds

Brewed Coffee Grounds

After brewing coffee, the used coffee grounds can be dried out and used in baking or cooking. Drying out the grounds can be done by spreading them out on a baking sheet and leaving them in the oven at a low temperature for a few hours.

Once the coffee grounds are dry, they can be ground up into a fine powder using a coffee grinder or food processor. This powder can then be used in recipes such as cakes, cookies, and even steak rubs.

Another way to use brewed coffee grounds is to add them to smoothies or protein shakes. The coffee grounds can add a subtle coffee flavor and provide an energy boost.

Unbrewed Coffee Grounds

Unbrewed coffee grounds can also be used in cooking and baking. However, they should be used sparingly as they can be very bitter and overpowering.

One way to use unbrewed coffee grounds is to sprinkle them on top of oatmeal or yogurt for added texture and flavor. They can also be used as a dry rub for meat or added to marinades for a subtle coffee flavor.

Another way to use unbrewed coffee grounds is to mix them with spices and herbs to create a unique seasoning blend. This blend can be used on vegetables, meats, and even popcorn.

What can you use coffee grounds for?

What can you use coffee grounds for

Coffee grounds have more uses than just brewing a delicious cup of coffee, if, like me, you don’t feel like eating them.

In fact, there are many uses for coffee grounds around the home and garden. Here are a few ways you can use coffee grounds:

  • Fertilizer: Coffee grounds are rich in nitrogen and other nutrients that can help plants grow. They can be added to soil to provide plants with a boost of nutrients.
  • Compost: Coffee grounds can be added to compost to help break down organic matter and create nutrient-rich soil for plants.
  • Insect repellent: Certain compounds found in coffee, such as caffeine and diterpenes, can repel insects and pests. Coffee grounds can be sprinkled around plants to keep pests away.
  • Cleaning agent: Coffee grounds can be used as an abrasive cleaning agent for pots, pans, and other surfaces. They can help scrub away stubborn stains and grime.

Aside from their practical uses, coffee grounds can also be used in cooking and baking. They can add a rich, earthy flavor to dishes and desserts. Here are a few ways chefs and dietitians recommend using coffee grounds in cooking:

  • Brownies: Adding finely ground coffee grounds to brownie batter can enhance the chocolate flavor and make the brownies richer and more robust.
  • Steak rub: Mixing coffee grounds with spices and herbs can create a flavorful rub for steaks and other meats.
  • Smoothies: Adding a spoonful of coffee grounds to a smoothie can add a boost of caffeine and a rich, earthy flavor.

While coffee grounds can be used in a variety of ways, it’s important to note that they should not be consumed in large quantities. Eating too many coffee grounds can lead to digestive issues and caffeine overdose. However, when used in moderation, coffee grounds can be a versatile and useful addition to any home or garden.


So, can you eat coffee grounds? The answer is yes, but with some caveats. It is important to note that only organic coffee beans are safe to consume, as they are free from harmful chemicals and pesticides. Additionally, coffee grounds are a rich source of antioxidants, which can help reduce the risk of cancer.

While coffee grounds are safe to eat in small amounts, it is important not to overdo it. Consuming too much caffeine can lead to negative side effects, such as insomnia, anxiety, and jitteriness. It is also important to note that coffee grounds should not be used as a replacement for a balanced and healthy diet.

So go ahead and try eating coffee grounds if you’re curious, but be sure to do so safely and responsibly. And who knows, you may just discover a new favorite snack!
