Specific Carbohydrate (SCD) Diet vs Low Fermentation Diet

When it comes to gut health, there are a lot of different diets out there that claim to help. Two diets that are often compared are the Specific Carbohydrate Diet (SCD) and the Low Fermentation Diet. In this article, we'll take a deep dive into both diets, so you can decide which one is right for you.

What is the Specific Carbohydrate Diet (SCD)?

The Specific Carbohydrate Diet (SCD) was originally developed by Dr. Sidney Haas in the 1920s as a treatment for inflammatory bowel disease (IBD). The idea behind the diet is that by removing complex carbohydrates, which are difficult to digest, from the diet, the gut can heal and inflammation can be reduced.

The SCD is a strict diet that eliminates all grains, processed foods, refined sugars, and most dairy products. It allows only certain fruits, vegetables, and meats, as well as some dairy products that are low in lactose. The goal is to starve harmful bacteria in the gut, which can thrive on these complex carbohydrates.

Research has shown that the SCD can be effective in reducing symptoms of IBD, such as abdominal pain, diarrhea, and bloating. In addition, some people with other digestive disorders, such as celiac disease and irritable bowel syndrome (IBS), have also reported improvement in their symptoms on the SCD.

What is a Low Fermentation Diet?

A Low Fermentation Diet is based on the idea that certain foods are more likely to cause gas and bloating in the gut, due to their fermentation properties. The diet aims to reduce these symptoms by eliminating or limiting foods that are high in FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols), which are types of short-chain carbohydrates that can be difficult to digest.

The Low Fermentation Diet typically involves eliminating or limiting certain fruits, vegetables, and grains that are high in FODMAPs, as well as dairy products that are high in lactose. It also recommends eating smaller, more frequent meals to help reduce digestive symptoms.

Research has shown that a Low Fermentation Diet can be effective in reducing symptoms of irritable bowel syndrome (IBS), such as abdominal pain, bloating, and diarrhea. In fact, a study published in the Journal of Gastroenterology and Hepatology found that 76% of participants with IBS who followed a Low Fermentation Diet experienced significant improvement in their symptoms.

The Science Behind SCD and Low Fermentation Diets

There is some scientific evidence to support the use of both SCD and Low Fermentation diets for gut health. Studies have shown that SCD may be effective in reducing symptoms of IBD, such as abdominal pain and diarrhea. It may also be effective in reducing inflammation in the gut.

Low Fermentation diets have been shown to be effective in reducing symptoms of irritable bowel syndrome (IBS), such as bloating and gas. They may also be helpful for people with other digestive disorders, such as inflammatory bowel disease and celiac disease.

Additionally, SCD and Low Fermentation diets may also have benefits for mental health. Research has suggested that the gut-brain axis, which is the connection between the gut and the brain, plays a role in mental health. By improving gut health through these diets, it may also have a positive impact on mental health conditions such as anxiety and depression.

Furthermore, these diets may also have potential benefits for weight management. SCD and Low Fermentation diets are typically low in processed foods and high in whole, nutrient-dense foods. This can lead to improved satiety and reduced calorie intake, which may result in weight loss or weight maintenance.

How do SCD and Low Fermentation Diets differ?

While both diets aim to improve gut health, they differ in their approach. SCD focuses on removing complex carbohydrates from the diet, while Low Fermentation diets focus on reducing foods that are high in FODMAPs and can cause gas and bloating.

SCD is also a more restrictive diet than Low Fermentation, as it eliminates grains and most dairy products, while Low Fermentation allows some grains and low-lactose dairy products.

Another key difference between SCD and Low Fermentation diets is their recommended duration. SCD is typically followed for a longer period of time, often up to two years, while Low Fermentation is usually followed for a shorter period of time, around six to eight weeks. Additionally, SCD is often recommended for individuals with more severe digestive issues, such as Crohn's disease or ulcerative colitis, while Low Fermentation may be recommended for individuals with milder digestive issues or those looking to improve overall gut health.

Benefits and drawbacks of the Specific Carbohydrate Diet

The benefits of the SCD include improved gut health, reduced inflammation, and relief from symptoms of IBD. However, the diet can be difficult to follow and may lead to nutrient deficiencies if not done properly. It can also be socially isolating, as many foods are off-limits.

Another potential drawback of the SCD is that it may not work for everyone. While some people with IBD may see significant improvements in their symptoms, others may not experience any noticeable changes. Additionally, the diet may not be sustainable in the long-term for some individuals, as it requires strict adherence and may limit food choices.

Benefits and drawbacks of the Low Fermentation Diet

The benefits of the Low Fermentation Diet include reduced symptoms of IBS, improved gut health, and a more balanced microbiome. However, the diet can also be restrictive and may lead to nutrient deficiencies if not done properly. It can also be difficult to follow when eating out or traveling.

Another benefit of the Low Fermentation Diet is that it can help reduce inflammation in the body. This is because the diet eliminates foods that can trigger inflammation, such as processed foods and sugar. By reducing inflammation, the diet may also help improve symptoms of other inflammatory conditions, such as arthritis and eczema.

On the other hand, one of the drawbacks of the Low Fermentation Diet is that it can be challenging to maintain in the long term. The diet requires a significant amount of planning and preparation, as many foods need to be eliminated or limited. Additionally, some people may find the diet too restrictive, which can lead to feelings of deprivation and ultimately make it harder to stick to.

SCD vs Low Fermentation Diet: Which is better for gut health?

Both SCD and Low Fermentation diets have been shown to be effective in improving gut health, but the choice between them depends on your individual needs and preferences. SCD may be more effective for people with IBD, while Low Fermentation diets may be more helpful for people with IBS or other digestive disorders.

It is important to note that both diets require strict adherence and may be difficult to follow for some individuals. SCD involves eliminating all grains, dairy, and processed foods, while Low Fermentation diets limit high FODMAP foods such as garlic, onions, and certain fruits and vegetables. It is recommended to work with a healthcare professional or registered dietitian to determine which diet may be best for you and to ensure proper nutrient intake while following the diet.

How to start implementing the Specific Carbohydrate Diet

If you're interested in trying the SCD, it's important to do your research and work with a registered dietitian to ensure that you're getting all of the nutrients you need. Some tips for getting started include familiarizing yourself with the allowed foods, meal planning and prep, and finding support from others who have tried the diet.

It's also important to note that the SCD can be a difficult diet to follow, especially in the beginning. You may experience symptoms such as bloating, gas, and diarrhea as your body adjusts to the new way of eating. It's important to stick with it and give your body time to adapt. Keeping a food diary can also be helpful in identifying trigger foods and tracking your progress.

How to start implementing the Low Fermentation Diet

If you're interested in trying the Low Fermentation Diet, it's important to work with a registered dietitian to ensure that you're getting all of the nutrients you need. Some tips for getting started include familiarizing yourself with the high-FODMAP foods to avoid, meal planning and prep, and finding support from others who have tried the diet.

It's also important to keep in mind that the Low Fermentation Diet is not a one-size-fits-all approach. Everyone's digestive system is different, so it's important to listen to your body and make adjustments as needed. Additionally, it's important to be patient and give the diet time to work. It may take a few weeks to see improvements in your symptoms.
