What Beans Are Allowed on the Specific Carbohydrate Diet?

4 min read

Developed in the 1920s, the Specific Carbohydrate Diet (SCD) is a grain-free, lactose-free nutritional plan that has been used to manage symptoms of certain digestive disorders. When following the SCD, not all beans are created equal, and proper preparation is key to making them digestible and safe for consumption.

Quick Summary

The Specific Carbohydrate Diet permits certain dried beans and legumes only after a healing period and requires specific soaking and cooking methods. Legumes like navy, lima, and black beans are allowed, while garbanzo and pinto beans are prohibited. The strict preparation helps break down complex starches that can be difficult for compromised digestive systems to process.

Key Points

  • Legumes are a later addition: Allowed beans and legumes should only be introduced into the SCD after digestive symptoms have improved, typically after a few months.

  • Proper preparation is mandatory: All beans must be purchased dried and undergo a strict process of soaking, draining, and prolonged boiling to remove indigestible starches.

  • Specific varieties are allowed: Legal beans include navy, lima, lentils, split peas, black beans, and kidney beans, provided they are prepared correctly.

  • Many common beans are prohibited: Illegal legumes include chickpeas, pinto beans, soybeans, cannellini beans, and fava beans, among others.

  • Canned beans are never allowed: All commercially canned beans are prohibited on the SCD due to additives and inconsistent processing.

  • Salt is added at the end: To ensure proper softening, salt should only be added to cooked beans after the boiling and simmering process is complete.

  • Recipes must be adapted carefully: When cooking with legal beans, use only SCD-compliant ingredients and follow the strict preparation methods.

Understanding the Role of Beans on the SCD

The Specific Carbohydrate Diet (SCD) is designed to alleviate digestive distress by removing complex carbohydrates, which are believed to feed harmful gut bacteria. Legumes contain a type of complex carbohydrate that can be particularly difficult for individuals with compromised digestion to break down. For this reason, the SCD strictly limits which beans are permitted and requires a precise preparation method to remove these indigestible compounds. Introducing beans is typically a later stage addition to the diet, recommended only after significant symptom improvement has been observed for at least three months.

Allowed Beans on the SCD

For those who have reached a stage of the diet where legumes can be tolerated, several types of dried beans are considered 'legal'. These must be purchased dry, as all canned beans are prohibited due to potential additives and the inability to control the preparation process.

  • Navy Beans: A versatile white bean that is commonly allowed. It works well in soups and purees.
  • Lima Beans: These large, flat beans are an acceptable option for adding variety to meals.
  • Black Beans: Often introduced later in the healing process, black beans can be added once the gut is more healed.
  • Kidney Beans: Red kidney beans are permitted, but again, only after the initial healing phase.
  • Split Peas: A good source of protein and fiber that is allowed on the diet.
  • Lentils: Both red and green lentils are acceptable, but must be properly soaked and cooked.
  • Adzuki Beans: These smaller beans are also on the list of approved legumes.

Legumes to Avoid on the SCD

Many common beans and legumes are strictly forbidden on the SCD because their carbohydrate structures are not compatible with the diet's principles. These include:

  • Chickpeas (Garbanzo Beans): A common legume that is explicitly listed as illegal.
  • Pinto Beans: These are not allowed on the diet.
  • Soybeans and Soy Products: All soy, including tofu and soy milk, is prohibited.
  • Fava Beans: Also known as broad beans, these are not permitted.
  • Cannellini Beans: Another variety of white bean that is considered illegal.
  • Mung Beans: This type of legume is also on the list of foods to avoid.

The Importance of Proper Preparation

Successful incorporation of beans into the SCD depends heavily on a specific, time-intensive preparation process. This method helps to remove the indigestible starches and compounds that can cause inflammation and digestive upset.

  1. Initial Sorting: First, pick through your dried beans to remove any small stones or debris.
  2. Overnight Soak: Place the beans in a large bowl and cover with water (using a ratio of 4 parts water to 1 part beans). Let them soak for 10-12 hours at room temperature.
  3. Rinse and Discard Water: After soaking, drain the water completely and rinse the beans thoroughly under cold running water. The soaking water, which contains the indigestible sugars, must be discarded.
  4. Boil and Skim: Place the rinsed beans in a pot with fresh, clean water. Bring the water to a hard boil, and as it boils, use a spoon to skim off any foam that rises to the surface. This step is critical for removing difficult starches and shouldn't be skipped.
  5. Long Simmer: After the initial hard boil, reduce the heat to a low simmer. Cover the pot and cook for at least two hours, or until the beans are completely soft and mash easily. The goal is to overcook them slightly to ensure all starches are broken down.
  6. Add Salt Last: Do not add salt until the beans are fully cooked, as salt can prevent the skins from softening and make them harder to digest.

Comparison of SCD Legal and Illegal Beans

Feature SCD Legal Dried Beans SCD Illegal Legumes
Carbohydrate Type Easily digestible monosaccharides post-preparation Complex polysaccharides (difficult to digest)
Examples Navy, Lima, Black, Kidney, Lentils, Split Peas, Adzuki Chickpeas, Pinto, Fava, Soybeans, Mung Beans, Cannellini
Preparation Requires extensive soaking, draining, and prolonged cooking None (most are inherently illegal)
Available Format Must be purchased dry and prepared at home All canned versions are prohibited
Dietary Stage Added later, after symptoms have improved Excluded from all stages

SCD-Friendly Bean Recipes

Once you are ready to introduce legal beans, they can be a great addition to your diet. Consider experimenting with these simple, compliant recipes:

Navy Bean Puree: Prepare a batch of navy beans following the strict SCD soaking and cooking instructions. Once fully cooked and soft, mash them with a potato masher or blend in a food processor with a little bit of the cooking liquid, some olive oil, and a touch of salt. This puree can serve as a soup thickener or an extender for baked goods using nut flours.

Simple Lentil Soup: Start with a base of compliant homemade broth. Add properly soaked and cooked lentils, diced carrots, and chopped celery. Simmer until all vegetables are tender. Season with legal herbs and spices like parsley and thyme.

SCD Black Bean Patties: For those who can tolerate black beans, prepare and mash them thoroughly. Mix with compliant seasonings like cumin and paprika, along with some SCD-legal nut flour as a binder. Form into patties and pan-fry in coconut oil until golden brown.

Conclusion

While the Specific Carbohydrate Diet can feel restrictive, it is possible to incorporate certain beans and legumes with careful attention to detail. The list of allowed beans, including navy, lima, and black beans, provides valuable sources of protein and fiber for those who have passed the initial healing phases. The key to success is adhering to the strict soaking and cooking protocol, which breaks down complex starches and makes these legumes digestible. By following these guidelines, individuals on the SCD can safely expand their culinary horizons and add nutrient-dense options back into their diets.

Frequently Asked Questions

No, all commercially canned beans are prohibited on the SCD. This is because they contain preservatives and additives, and the cooking process cannot be guaranteed to remove the indigestible starches required by the diet.

Legumes should only be added after symptoms have improved consistently for at least three months. This allows the gut to heal sufficiently before introducing these more complex foods.

The long soaking process is crucial for removing the complex indigestible sugars that can exacerbate digestive issues. Soaking for 10-12 hours helps dissolve a significant portion of these troublesome carbohydrates.

No, chickpeas and garbanzo beans are explicitly listed as illegal legumes and should be avoided on the Specific Carbohydrate Diet.

The beans are ready when they are completely soft and mash easily between your fingers. A long, slow simmer after an initial hard boil is necessary to ensure the starches are fully broken down.

Yes, a pressure cooker can be used. Many find it shortens the cooking time significantly after the initial overnight soak and rinse are completed. Ensure the beans are fully tender before eating.

The 'gas-free soak' involves bringing beans to a boil for 2-3 minutes, then covering and setting them aside overnight. The soaking water is then discarded and the beans are thoroughly rinsed before cooking to remove indigestible sugars.
