Specific Carbohydrate Diet

Specific Carbohydrate Diet

The Specific Carbohydrate Diet (SCD) is a specialized nutritional protocol designed to support digestive health by removing complex carbohydrates that can be difficult to break down. This rigorous grain-free, gluten-free, soy-free, and sugar-free plan focuses on "legal" monosaccharides—simple sugars found in fruits and honey—while eliminating "illegal" disaccharides and polysaccharides like lactose, sucrose, and starches. This approach is often utilized to help manage chronic digestive challenges by aiming to starve harmful gut bacteria and reduce intestinal inflammation. This framework may be particularly supportive if your PlexusDx report indicates variations in inflammation-regulating genes such as IL23R, TNF, or IL6, which can influence how your body manages immune responses in the gut. Furthermore, because this restrictive plan can impact nutrient intake, aligning your food choices with your genetic needs—such as those linked to MTHFR (folate metabolism) or BCO1 (vitamin A conversion)—can help you maintain nutritional balance while following the protocol.

This program is built on a foundation of scientific considerations for gut healing and nutrient density. Since the diet excludes many standard fiber sources like grains, it carefully integrates high-fiber fruits, vegetables, and nuts to support digestive regularity and microbiome health without feeding pathogenic bacteria. To counteract potential nutrient gaps common in restrictive diets, the meal plan emphasizes foods rich in essential vitamins and minerals often depleted in digestive conditions. Key evidence-backed recommendations for this plan include:

• Prioritize fiber-rich "legal" foods: Aim for approximately 39 grams of daily fiber through allowed fruits, vegetables, and nuts to support digestive health.
• Boost immune function with trace minerals: Incorporate zinc-rich foods like chicken, beef, and almonds, along with selenium sources such as eggs to support anti-inflammatory pathways.
• Support bone health: actively include calcium and phosphorus sources like aged cheeses, sardines, and almonds to protect bone density.
• Focus on antioxidant intake: Consume Vitamin A and C-rich foods such as bell peppers, squash, and citrus fruits to help reduce oxidative stress in gut tissues.
• Ensure adequate B vitamins: counteract potential deficiencies by including plenty of leafy greens, poultry, and beef to support energy metabolism.

1. Locate the meal you wish to change on your daily planner.
2. Click the three dots (…) in the top right corner of the meal card.
3. Select “Swap recipe” from the dropdown menu.
4. Choose “Swap” to change just that single meal, or “Swap all” to replace it for the entire duration of the plan.
5. Keep clicking “Swap” to browse through alternative recipes until you find one that matches your specific restrictions (e.g., GF, DF, or egg-free).

Frequently Asked Questions About The Specific Carbohydrate Diet

What is the Specific Carbohydrate Diet (SCD) and who is it for?

The Specific Carbohydrate Diet (SCD) is a grain-free, gluten-free, soy-free, and sugar-free nutrition protocol designed to support digestive health. It removes complex carbohydrates that can be harder to break down and focuses on “legal” monosaccharides (like those in fruits and honey) while eliminating “illegal” disaccharides and polysaccharides (such as lactose, sucrose, and starch). It’s often used for chronic digestive challenges, especially when your goal is to help reduce intestinal inflammation and potentially limit harmful gut bacteria.

How can my PlexusDx report guide an SCD meal plan for inflammation and gut immune responses?

Your PlexusDx report may highlight variations in inflammation-regulating genes such as IL23R, TNF, or IL6, which can influence how your immune system responds in the gut. If your results suggest an inflammatory predisposition, an SCD approach may be especially relevant because it targets carbohydrate types that can be difficult to digest and may help support gut healing goals. The plan can also be adjusted to support nutrient balance based on genetics related to folate metabolism (MTHFR) or vitamin A conversion (BCO1), since restrictive diets can sometimes create nutrient gaps.

What foods and nutrient targets are emphasized when following the SCD?

The SCD meal plan prioritizes fiber-rich “legal” foods by aiming for about 39 grams of daily fiber from allowed fruits, vegetables, and nuts to support regularity and microbiome health. It also emphasizes immune and anti-inflammatory support with trace minerals (like zinc from chicken, beef, and almonds, and selenium from eggs), bone support using calcium and phosphorus sources (such as aged cheeses, sardines, and almonds), antioxidant support through vitamin A and C-rich foods (bell peppers, squash, and citrus), and adequate B vitamins from leafy greens and poultry or beef to support energy metabolism.
