What Happens If You Eat Too Many Cherries?

A 2019 review of studies published in the journal Nutrients noted that cherries are rich in anthocyanins and other polyphenols, which can reduce oxidative stress and inflammation. However, this fruit's otherwise healthy reputation can be tarnished by overconsumption, which can lead to negative side effects. This guide explains what happens if you eat too many cherries and the digestive and other health issues that can arise.

Quick Summary

Eating too many cherries can cause gastrointestinal discomfort, including bloating, cramps, gas, and diarrhea, primarily due to their fiber and natural sugar alcohol content. This is especially true for those with sensitive stomachs or IBS. While nutritious, overindulgence should be avoided.

Key Points

Digestive Issues: Overeating cherries can cause bloating, gas, and diarrhea due to their high fiber content and natural sugar alcohol (sorbitol).
FODMAP Sensitivity: For individuals with IBS or sensitive guts, large amounts of cherries, which are high in FODMAPs like fructose, can trigger discomfort.
Cherry Pit Safety: While swallowing an intact cherry pit is generally harmless, crushing or chewing it releases amygdalin, which can form toxic cyanide. Pits should always be removed, especially for children or when blending.
Moderate Portions Recommended: For most healthy adults, enjoying about one cup of pitted cherries a day is a healthy portion that provides benefits without adverse side effects.
Listen to Your Body: Individual tolerance to cherries varies. Start with smaller portions and monitor your body's reaction, especially if you have existing digestive issues.
Consider Sugar Content: Cherries contain natural sugar, and eating too many at once could cause a minor sugar spike. Diabetics should be particularly mindful of their intake.
Enjoy the Benefits Moderately: Cherries are rich in antioxidants and vitamins. Eating them in moderate amounts still delivers their anti-inflammatory and other health benefits.

Cherries are a celebrated seasonal fruit, packed with antioxidants and vitamins. However, even with all their health benefits, the phrase "too much of a good thing" applies. Overdoing it on this sweet snack can lead to some uncomfortable side effects, primarily affecting the digestive system. Understanding the reasons behind these issues can help you enjoy cherries in moderation without unwanted consequences.

The Digestive Toll of Too Many Cherries

The primary reason for discomfort after eating a large quantity of cherries is their effect on the digestive system. This is due to a combination of high fiber content, natural sugar alcohols, and other compounds.

Impact of Dietary Fiber

Cherries are a good source of fiber, which is generally beneficial for digestion. A single cup of cherries can contain around 3 grams of dietary fiber. For individuals who are not accustomed to a high-fiber diet, a sudden influx can overwhelm the digestive system. This can lead to:

Bloating and Gas: As the fiber ferments in the gut, it can produce excess gas, leading to a bloated feeling.
Diarrhea: The bulk and water-retaining properties of fiber can accelerate bowel movements, resulting in loose stools.

Effects of Sorbitol and FODMAPs

Cherries naturally contain sorbitol, a sugar alcohol that can act as a laxative. In sensitive individuals, particularly those with Irritable Bowel Syndrome (IBS), consuming large amounts of sorbitol can lead to significant digestive upset. Additionally, cherries contain fructose and are considered a high FODMAP food in larger servings, which can cause issues for people with fructose malabsorption or sensitive guts.

Other Potential Gastrointestinal Concerns

Beyond fiber and sorbitol, some people may have sensitivities to salicylates, naturally occurring chemicals also found in cherries. While not common, a salicylate sensitivity could contribute to stomach pain and other GI discomfort when overindulging in cherries.

Cyanide and Cherry Pits

One of the most concerning myths surrounding cherry overconsumption is the toxicity of the pits. It is crucial to understand the truth behind this risk.

The Toxic Compound: Cherry pits contain amygdalin, a compound that the body can convert into hydrogen cyanide when the pit is crushed or chewed.
Swallowing a Whole Pit: Swallowing a single, whole, intact cherry pit is generally not dangerous. The hard shell protects the inner kernel, and it will pass through the digestive system unchanged.
The Real Danger: The risk arises if the pit is chewed, crushed, or ground, which releases the amygdalin. This is why you should always remove pits before blending cherries into a smoothie.
Cyanide Poisoning Symptoms: While extremely rare from cherries, symptoms of cyanide poisoning can include headache, dizziness, nausea, vomiting, and difficulty breathing. If you or a child chews and ingests several pits and experiences symptoms, seek immediate medical help.

Navigating Cherry Overconsumption

To avoid the unpleasant side effects of eating too many cherries, moderation is key. For most healthy adults, a recommended portion is about 1 cup of pitted cherries a day. This amount can contribute beneficial nutrients without overwhelming the digestive system.

A Comparison of Cherry Consumption Scenarios


Feature	Moderate Consumption (Approx. 1 cup)	Excessive Consumption (Multiple cups)
Nutrient Benefit	High in antioxidants, fiber, Vitamin C, and potassium.	Nutrient benefits are overshadowed by adverse effects.
Digestive Impact	Fiber aids digestion and promotes regularity.	May cause bloating, gas, cramps, and diarrhea due to fiber and sorbitol.
Blood Sugar	Low glycemic index, promotes stable blood sugar levels.	High natural sugar intake could lead to a minor sugar headache or spike, especially for diabetics.
Pit Risk	Negligible risk if pits are removed; swallowing a whole one is usually harmless.	Increased risk of choking for children or potential cyanide release if pits are chewed/crushed.
Overall Effect	Contributes positively to overall health and wellness.	Can cause significant temporary discomfort and digestive distress.

Conclusion: Mindful Enjoyment is the Best Policy

Cherries are undoubtedly a nutritious and delicious fruit with many health benefits, from fighting inflammation to aiding sleep. However, like any food, they should be enjoyed in moderation. A standard serving of one cup is a great way to reap the rewards without experiencing negative gastrointestinal side effects. For those with sensitive digestive systems, particularly IBS, paying attention to portion sizes and listening to your body is essential. Always remember to remove the pits, especially when blending, to avoid the minuscule but present risk associated with their inner compounds. By being mindful of your intake, you can enjoy the peak season of this wonderful fruit without any regrets.

Frequently Asked Questions

Cherries are high in dietary fiber and contain sorbitol, a sugar alcohol. Both can lead to bloating and gas, especially when consumed in large quantities or by people unaccustomed to high-fiber diets.

Yes, excessive consumption of cherries can cause diarrhea. Their high fiber content acts as a laxative, and the sorbitol they contain can trigger a laxative effect in some people, particularly those with sensitive stomachs or IBS.

Cherry pits contain amygdalin, which can produce toxic hydrogen cyanide when crushed or chewed. However, swallowing a whole, intact pit is generally not dangerous, as the hard shell prevents the compound from being released. The danger is when the pit is broken open.

While individual tolerance varies, a standard healthy portion is typically around one cup of pitted cherries per day for most adults. Consuming multiple cups in one sitting can increase the likelihood of digestive discomfort.

People with Irritable Bowel Syndrome (IBS) should be cautious with their cherry intake. Cherries are considered a high FODMAP food in larger servings, and their sorbitol and fructose content can trigger digestive symptoms. Portion control is essential, and some may need to limit them.

If a child swallows an intact cherry pit, it will likely pass through their system without issue. The main risk is a choking hazard. If a child chews and ingests several pits or shows symptoms like nausea or headache, contact poison control or seek medical help.

Cherries contain natural sugars. While they have a low glycemic index and are fine in moderation, consuming a large quantity in one sitting could cause a temporary spike in blood sugar, which is particularly relevant for those managing diabetes.
