Understanding Tomatillo-Related Digestive Discomfort
While tomatillos are a staple in many cuisines and prized for their unique, tangy flavor, they are not without their potential to cause digestive distress in some people. For the majority, enjoying roasted tomatillos in a fresh salsa or other cooked dish is perfectly fine. However, certain attributes of this fruit, particularly when consumed in excess, raw, or by sensitive individuals, can lead to unpleasant side effects like diarrhea. It is important to understand the different reasons this may occur to minimize any risks.
High Fiber Content and Its Impact on Digestion
One of the most common reasons a person might experience diarrhea after eating tomatillos is their high dietary fiber content. Fiber is a crucial component of a healthy diet, aiding in regular bowel movements and promoting a healthy gut microbiome. However, a sudden or significant increase in fiber intake can overwhelm the digestive system, leading to a laxative effect. This is especially true for those with sensitive digestive systems or those who do not regularly consume a lot of fiber.
- How fiber works: Fiber adds bulk to stool by absorbing water in the colon. This makes it easier for food to pass through the digestive tract.
- The tipping point: When a large amount of fiber is consumed at once, this bulking effect can become too pronounced, speeding up bowel transit time and resulting in looser stools or diarrhea.
The Nightshade Connection: Alkaloids and Sensitivity
Tomatillos belong to the nightshade family of plants (Solanaceae), along with tomatoes, potatoes, and eggplant. This family contains naturally occurring compounds called alkaloids, which can sometimes trigger inflammatory reactions in susceptible individuals. The alkaloid present in tomatillos and other nightshades is tomatine. While the levels are generally low in ripe fruit, they are higher in unripe fruit, stems, and leaves.
For most people, the amount of tomatine in edible parts of the tomatillo is not a concern. However, some with a pre-existing intolerance or inflammatory conditions, such as arthritis, may be more sensitive to these compounds. Symptoms of sensitivity can include abdominal pain, gas, and, in some cases, diarrhea.
Allergic Reactions and Food Intolerances
A less common but more serious cause of digestive issues is a true food allergy or intolerance. A tomatillo allergy, while rare, can manifest with symptoms ranging from skin and eye itchiness to more severe gastrointestinal problems like vomiting, cramps, and diarrhea. A food intolerance, on the other hand, is a digestive system-based reaction rather than an immune response, and can be related to the fruit's FODMAP content.
Comparing Allergies vs. Intolerances
| Feature | Food Allergy | Food Intolerance |
|---|---|---|
| Cause | Immune system response to a protein | Digestive system difficulty breaking down a component, like a carbohydrate (FODMAP) |
| Severity | Can be mild to severe, potentially life-threatening | Generally less severe and not life-threatening |
| Symptoms | Itching, hives, swelling, vomiting, diarrhea | Diarrhea, gas, bloating, stomach pain |
| Onset | Can be immediate or within a few hours | Can be delayed, often dependent on quantity consumed |
The Significance of Ripeness and Preparation
The maturity of a tomatillo plays a significant role in its potential to cause digestive upset. Unripe, firm, bright green tomatillos have a higher concentration of the bitter alkaloid, tomatine, than ripe fruit. As the fruit ripens, the tomatine levels decrease, making the fruit generally safer to consume. This is why most recipes call for cooking tomatillos, as the heat helps further break down these compounds. Raw tomatillos in large quantities, especially when underripe, are more likely to cause issues.
The Importance of Proper Handling
Food contamination is another possible cause of diarrhea, and tomatillos are no exception. Bacteria like Salmonella can be transferred to the fruit during growth, harvesting, or preparation. To minimize this risk:
- Wash tomatillos thoroughly after removing the papery husk and before use.
- Use clean utensils and cutting boards.
- Cook tomatillos when possible, especially if you have concerns about raw consumption. Cooking helps kill potentially harmful bacteria.
Tips for Enjoying Tomatillos Safely
To minimize the risk of digestive issues, consider these practical tips:
- Choose Ripe Tomatillos: Look for firm fruits that have filled out their husks completely. The husks may even begin to split, revealing the fruit inside. Avoid those that are pale, white, or overly hard.
- Cook Your Tomatillos: Heating tomatillos in dishes like salsa verde or enchilada sauce helps break down alkaloids and softens the fiber, making them easier to digest.
- Start with Small Portions: If you are trying tomatillos for the first time or know you have a sensitive stomach, begin with a small amount to see how your body reacts. Monitor your response before increasing your intake.
- Listen to Your Body: If you experience persistent discomfort, bloating, or diarrhea after consuming tomatillos, it may be a sign of an intolerance or sensitivity. It's always best to consult a healthcare professional for personalized advice.

Conclusion
So, can tomatillos cause diarrhea? While it is not a widespread issue, the answer is yes, they can, particularly in individuals sensitive to nightshade alkaloids, those with food intolerances, or those who consume large quantities of high-fiber, underripe fruit. By selecting ripe tomatillos, cooking them properly, and starting with moderate portions, most people can enjoy this versatile ingredient without any negative digestive consequences. As with any dietary concern, understanding your own body's unique reactions is the best strategy for prevention.
