What Can You Eat on the Specific Carbohydrate Diet (SCD)?

Specific Carbohydrate Diet
SCD includes easily processed carbohydrates and whole unprocessed foods.

The specific carbohydrate diet (SCD) is potentially useful in people with inflammatory bowel disease. SCD mainly focuses on the intake of simple carbohydrates and unprocessed foods.

Experts claim that SCD:

  • Favorably changes the gut microbiome
  • Reduces the inflammatory neuropeptide levels in the gut
  • Reduces the gut lining inflammation

SCD involves eating carbohydrates that are easy to digest and avoiding foods that have high fiber or protein content.

  • SCD reduces symptoms of intestinal distress such as cramps and bloating.
  • SCD mainly has monosaccharide carbohydrates that are made of a single molecule and do not require an enzyme to break down. They should be easily absorbed and digested.
  • Complex carbohydrates are restricted because they are harder to digest

What is the specific carbohydrate diet?

The specific carbohydrate diet (SCD) usually restricts certain carbs that can help people with gastrointestinal issues, such as:

SCD usually limits legumes, lactose, or sucrose because they are harder to digest than other carb types.

What are the side effects of undigested carbohydrates?

Pediatrician Sidney Valentine Haas, MD, and his research developed this SCD. They published the book Management of celiac disease in the year 1951. Undigested carbohydrates (especially complex carbs) can cause gas formation, bacterial overgrowth, and gases. 

Hass suggested that if you remove or restrict certain carbohydrates available to intestinal bacteria, there will be reduced opportunities for bacterial overgrowth and production of toxins. This will help reduce gastrointestinal issues.

What foods should you eat and avoid on the specific carbohydrate diet?

SCD includes easily processed carbohydrates and whole unprocessed foods.

Tips to prepare for SCD include:

  • Restrict certain carbohydrates that are never fully digested.
  • Only eat foods that you can easily digest.
  • This is not a short-term diet for weight loss.
  • This diet helps treat gastrointestinal diseases.

What are the pros of specific carbohydrate diet?

The efficacy of the specific carbohydrate diet (SCD) is quite limited. Studies suggest that restricting carbohydrates as a gastrointestinal treatment may help people with undiagnosed gastrointestinal distress and bloating.

Helps manage Crohn’s disease

In a study published in 2017 in the Journal of Pediatric Gastroentrology and Nutrition, researchers found that nutrient intake in people with pediatric inflammatory bowel diseases was adequate compared with that in a healthy population. Close monitoring with a multidisciplinary team for people using SCD as an alternative and adjunct therapy is recommended to ensure positive outcomes in the overall health of the people.

  • SCD is a complete diet with an appropriate intake of nutrients and micronutrients.
  • Vitamin D evaluation should be done on people with SCD.

Helps manage gastrointestinal symptoms

In a recent review article “Pediatric Inflammatory Bowel Disease” in the International Journal of Clinical Practice, researchers have found that SCD helps in flare-ups of Crohn’s disease and ulcerative colitis.

What are the cons of specific carbohydrate diet?

You should be aware of the disadvantages of the specific carbohydrate diet (SCD) and consult a registered healthcare professional and dietician before attempting it.

Restricts nutrients

SCD eliminates certain nutrient-dense foods that include grain-based flour, grains, bread, and starchy vegetables that provide valuable nutrition. This diet specifically reduces nutrients and minerals.

In a study published in 2017, researchers found that 100 percent of participants were below the level of recommended daily allowance for vitamin D; 75 percent of daily intake was less than what is recommended for calcium.

Requires work

SCD requires a multidisciplinary team approach and good patient compliance for best outcomes according to the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition.

No specific support

The North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition and few scientific centers support this diet as therapy.

Does specific carbohydrate diet a healthy choice?

Talk to your registered healthcare professional and dietician before going for a specific carbohydrate diet (SCD). They might recommend modifications to get proper nutrients and minerals.

Low-FODMAP diet works best to treat gastrointestinal issues; this is not a weight loss diet. This diet is used for the treatment of proper digestive health. 

The United States Department of Agriculture suggests eating plenty of legumes, whole grains, and dairy products. SCD eliminates many of these foods. SCD does not meet the current recommendations set by nutrition experts.

Exercise, sleep, and other lifestyle factors play a major role in overall well-being. The best diet should be balanced and fits your lifestyle.
