What is the downside of farro? Understanding its limitations

4 min read

While farro is celebrated as a nutritious ancient grain rich in fiber and protein, it's crucial to understand the potential downsides of farro before making it a dietary staple. These considerations range from its gluten content and impact on digestion to nutrient absorption and cooking requirements.

Quick Summary

Farro's drawbacks include its high gluten content, making it unsuitable for those with celiac disease or gluten sensitivity. Other issues are potential digestive discomfort from its high fiber and the presence of phytic acid, which can inhibit mineral absorption.

Key Points

  • Contains Gluten: Farro is a type of wheat and is not safe for individuals with celiac disease, gluten sensitivity, or a wheat allergy.

  • Causes Digestive Issues: The high fiber content can lead to gas, bloating, and discomfort, especially if not introduced gradually into a diet.

  • Inhibits Mineral Absorption: Phytic acid in farro's bran can hinder the absorption of essential minerals like iron, zinc, and magnesium.

  • Requires Proper Cooking: Achieving the desired chewy texture can be challenging, as overcooking leads to mushiness and undercooking results in toughness.

  • Moderation for Carb Management: Like other grains, farro is carb-heavy, and portion control is important for those managing blood sugar levels or watching caloric intake.

  • Not a Complete Protein: Unlike quinoa, farro lacks all nine essential amino acids, meaning it should be paired with other protein sources for vegans and vegetarians.

  • Preparation is Key: Soaking farro is recommended to improve digestibility and reduce phytic acid, making nutrients more bioavailable.

Farro, a type of ancient wheat, is often praised for its hearty texture and nutritional profile, but it comes with several notable downsides that consumers should be aware of. Understanding these limitations is key to incorporating farro safely and effectively into a diet, especially for those with specific health concerns.

Farro is Not Gluten-Free

One of the most significant downsides of farro is that, as a form of wheat, it contains gluten. This makes it an inappropriate choice for anyone with celiac disease, non-celiac gluten sensitivity, or a wheat allergy. While some people with mild intolerances may find ancient wheats like farro easier to digest than modern wheat, it is never a safe option for those who must follow a strict gluten-free diet. For these individuals, consuming farro can trigger an immune response that harms the small intestine and leads to various digestive and systemic symptoms, from bloating and gas to long-term intestinal damage. For those who need to avoid gluten, alternatives such as quinoa, amaranth, or brown rice are much safer and equally nutritious choices.

Potential for Digestive Discomfort

Another major concern, especially for those new to high-fiber diets, is the risk of digestive issues. Farro is exceptionally high in fiber, which is typically a positive attribute. However, introducing too much fiber too quickly can overwhelm the digestive system, leading to uncomfortable side effects such as:

  • Bloating
  • Gas
  • Stomach cramps
  • Constipation or diarrhea

To mitigate these symptoms, it's recommended to increase farro intake gradually and ensure you drink plenty of water. Proper hydration is essential for fiber to move through the digestive system smoothly. While the fiber in farro can improve gut health over time by feeding beneficial bacteria, an abrupt dietary change can cause temporary distress.

Phytic Acid Affects Mineral Absorption

Like many whole grains, farro contains phytic acid, an antinutrient found in the outer bran layer. Phytic acid can bind to important minerals like iron, zinc, magnesium, and calcium, forming compounds that inhibit their absorption in the body. This is particularly relevant for those with existing mineral deficiencies. However, the mineral-binding effects of phytic acid can be reduced with proper preparation. Cooking alone helps, but processes like soaking the grains for several hours or overnight, sprouting, or fermentation are more effective. Soaking also has the added benefit of reducing cooking time.

Cooking Can Be Tricky

Preparing farro to achieve the ideal texture can be a learning process. The cooking time and water absorption vary depending on the type of farro used (pearled, semi-pearled, or whole).

  • Pearled farro, with the bran removed, cooks the fastest but has less fiber and nutrients.
  • Whole farro, retaining the bran, is the most nutritious but takes the longest to cook and often requires soaking.
  • Semi-pearled farro is a compromise, offering a balance of cooking time and nutritional content.

Overcooking can result in a soft, mushy texture, while undercooking leaves the grains unpleasantly tough. Unlike rice, farro doesn't absorb all the cooking liquid, so it's best to cook it like pasta in a large pot of boiling water and drain the excess.

Nutritional Considerations and Comparison to Quinoa

Despite its health benefits, farro is still relatively high in carbohydrates, making portion control important, especially for those watching their calorie intake or managing blood sugar levels. While farro is a nutritious choice, it's worth comparing it to other whole grain alternatives like quinoa, which offer different profiles. Notably, quinoa is a complete protein, containing all nine essential amino acids, whereas farro is not.

Feature Farro Quinoa
Gluten Contains Gluten Gluten-Free
Protein Good Source, Not Complete Excellent Source, Complete
Fiber Very High Good Source
Essential Minerals Good Source (Zinc, Magnesium, Niacin) Good Source (Magnesium, Manganese, Phosphorus)
Phytic Acid Present (requires soaking for best absorption) Present (requires rinsing to remove saponin)
Nutrient Absorption Can inhibit absorption if not prepared properly Minimal concerns

Additional Considerations

Beyond the main issues, some individuals may need to consider other factors:

  1. Oxalates: Some sources note that farro is high in oxalates, which could be problematic for those prone to kidney stones.
  2. Wheat Allergy: In addition to celiac disease, a full-blown wheat allergy makes farro unsuitable due to its wheat content.
  3. Histamine Intolerance: Some people with this sensitivity might react to farro, though it's considered moderately low in histamines.

Conclusion

While farro offers a fantastic array of nutrients, its main downsides center around its gluten content, potential for digestive discomfort due to high fiber, and the presence of phytic acid that can hinder mineral absorption. Proper preparation, such as soaking, can mitigate the phytic acid issue, and a gradual increase in portion size helps the digestive system adjust to the high fiber. For those with celiac disease, a gluten sensitivity, or wheat allergy, however, farro must be avoided entirely. By understanding these limitations, you can make an informed decision about whether farro is the right fit for your dietary needs and health conditions.

Frequently Asked Questions

No, farro is not suitable for people with celiac disease. It is a form of wheat and contains gluten, which can cause a harmful immune reaction in individuals with this condition.

Yes, farro's high fiber content can cause bloating, gas, and other digestive discomfort, particularly if you are not accustomed to eating a high-fiber diet.

You can reduce phytic acid by soaking the farro in water for several hours or overnight before cooking. Adding a splash of lemon juice or vinegar to the soaking water can further enhance the effect.

Pearled farro has the outer bran layer completely removed, resulting in a quicker cooking time but fewer nutrients. Whole farro retains the bran, offering more fiber and nutrients but requiring longer cooking and often soaking.

No, farro is not a low-carb grain. Like most grains, it is relatively high in carbohydrates, so moderation is key, especially if you are on a low-carb diet or managing blood sugar.

Yes, the phytic acid present in whole farro can bind to and reduce the absorption of certain minerals like iron, zinc, and magnesium. Soaking and proper preparation can help to minimize this effect.

Yes, excellent gluten-free alternatives include quinoa, brown rice, millet, and amaranth. Quinoa is an especially good substitute as it is also a complete protein.

No, people with a wheat allergy should not eat farro, as it is a type of wheat.
