What Does Eating Coffee Grounds Do? Exploring the Benefits and Risks

I am sure that many coffee lovers out there have wondered about the possibilities of consuming coffee grounds. As a coffee enthusiast myself, I have also delved into this topic to understand the potential benefits and risks it may pose. In this article, I will be exploring what eating coffee grounds can do to our bodies, discussing both the advantages and challenges that come with this practice.

What are Coffee Grounds?

Coffee grounds are the leftover residue that remains after brewing coffee. When we make coffee, we add hot water to ground coffee beans, which extracts the flavor and aroma, leaving behind the grounds. Typically, coffee beans are ground to varying degrees of coarseness or fineness based on the brewing method. These grounds are commonly disposed of, but some individuals are beginning to view them as a possible nutritional boost or ingredient for different recipes.

The Nutritional Value of Coffee Grounds

At first glance, it may seem that coffee grounds have little to offer in terms of nutrition. However, upon closer examination, we can discover several elements that make coffee grounds potentially beneficial when consumed in moderation.

1. Fiber

One notable component of coffee grounds is fiber. A 2017 study published in the journal ‘Nature’ suggests that coffee grounds contain a significant amount of dietary fiber, precisely the water-insoluble fraction. Fiber is essential for maintaining healthy digestion and reducing the risk of numerous chronic diseases, such as heart disease and diabetes. Incorporating coffee grounds into your diet can be a natural way to increase your fiber intake.

2. Antioxidants

Coffee grounds are also rich in antioxidants, which play a crucial role in protecting our bodies from harmful molecules known as free radicals. Antioxidants have been linked to various health benefits, including reducing the risk of chronic conditions like cancer and heart disease. Some studies have even suggested that coffee is one of the primary sources of antioxidants in the Western diet. By consuming coffee grounds, you can potentially increase your antioxidant intake.

Possible Benefits of Eating Coffee Grounds

Now that we understand the nutritional value of coffee grounds let’s explore the possible benefits that consuming them can offer.

1. Improved Digestion

As mentioned earlier, coffee grounds contain dietary fiber, which promotes healthy digestion. Fiber adds bulk to our stool and helps prevent constipation by ensuring regular bowel movements. Incorporating coffee grounds into your diet, especially if you struggle with maintaining regularity, may help improve your digestive health.

2. Increased Antioxidant Intake

As coffee grounds pack a powerful antioxidant punch, consuming them can contribute to boosting your overall antioxidant intake. Antioxidants are known for their ability to reduce inflammation in the body, potentially benefiting general health and well-being.

3. Environmentally Friendly Option

One often overlooked benefit of eating coffee grounds is the positive environmental impact it can have. By repurposing the grounds, you are diverting waste from the landfill, reducing your ecological footprint. Choosing to consume coffee grounds instead of throwing them away is an eco-friendly choice that aligns well with sustainable living practices.

Risks and Considerations

While there are potential benefits to eating coffee grounds, it is crucial to be aware of the risks and considerations associated with this practice.

1. Pesticide Residue

Coffee beans are commonly treated with pesticides during cultivation to protect against pests and diseases. While the majority of pesticides are removed during the brewing process, some residue may remain in the grounds. Consuming coffee grounds exposes you to the risk of ingesting these residues, which can have adverse health effects. It is best to ensure that the coffee beans used to make the grounds are sourced from organic, pesticide-free farms.

2. Digestive Issues

While coffee grounds can provide additional fiber, consuming excessive amounts may lead to digestive issues such as bloating, gas, or even diarrhea. It is essential to moderate your intake and gradually introduce coffee grounds to your diet to avoid any discomfort.

3. Caffeine Overconsumption

Coffee grounds still contain caffeine, even after brewing. Consuming large quantities of coffee grounds could potentially result in consuming excessive amounts of caffeine, leading to side effects such as jitters, increased heart rate, or difficulty sleeping. It is crucial to be mindful of your overall caffeine consumption and consider the total intake from all sources, including brewed coffee and other caffeinated products.

Alternative Uses for Coffee Grounds

If consuming coffee grounds does not appeal to you or you are concerned about the potential risks, there are various alternative ways to put those grounds to good use.

1. Composting

Coffee grounds are an excellent addition to compost as they help enrich the soil with organic matter. The grounds’ high nitrogen content contributes to the decomposition process, providing vital nutrients to your plants. Instead of eating coffee grounds, consider composting them to promote sustainable gardening practices.

2. Body Scrub

Coffee grounds can be used as an exfoliating body scrub. The texture of the grounds helps remove dead skin cells, leaving your skin smoother and softer. By mixing used coffee grounds with some coconut oil or other carrier oils, you can create a rejuvenating scrub with a delicious coffee aroma.

3. Pest Deterrent

Coffee grounds can be a natural deterrent for pests such as slugs and snails. By sprinkling the grounds around your plants or garden, you can help protect them from these unwanted visitors. Coffee grounds also act as a barrier to ants, keeping them away from areas where they are not welcome.


To conclude, while there are potential benefits to consuming coffee grounds, it is vital to exercise caution and moderation. Coffee grounds can contribute to your daily fiber intake and provide a boost of antioxidants, benefiting your digestion and overall health. However, it is crucial to be aware of potential risks such as pesticide residue, digestive issues, and caffeine overconsumption. If you are uncertain or uncomfortable with eating coffee grounds, there are alternative uses that allow you to still benefit from their properties, such as composting or using them as a natural body scrub. Ultimately, it is essential to listen to your body and make informed choices that align with your individual health goals and preferences.
