The Specific Carbohydrate Diet (SCD) is a restrictive, grain-free diet designed to help manage gastrointestinal conditions such as Crohn's disease, ulcerative colitis, and celiac disease. It allows easily digestible foods like fresh fruits, most vegetables, unprocessed meats, and homemade yogurt while banning grains, starches, processed foods, and lactose-heavy dairy. The diet aims to reduce harmful gut bacteria by removing hard-to-digest carbs, including disaccharides and polysaccharides. Fructooligosaccharides (FOS) are common dietary oligosaccharides that cannot be broken down by human enzymes and are found in onions, garlic, leeks, certain beans, and cashews. While it is surprising that several dietary sources of oligosaccharides are allowed on the SCD, it is important to note that the diet has had many modifications over the years and continues to be modified based on individual responses to different foods.
| Characteristics | Values |

Fructooligosaccharides are dietary oligosaccharides, which are allowed on the SCD diet
The Specific Carbohydrate Diet (SCD) is a restrictive, grain-free diet designed to help manage gastrointestinal conditions such as Crohn's disease, ulcerative colitis, and celiac disease. The diet allows easily digestible foods while banning grains, starches, processed foods, and lactose-heavy dairy. The goal is to eliminate hard-to-digest carbohydrates from the diet that can be fermented by microbes in the intestines, leading to intestinal injury and inflammation.
Fructooligosaccharides (FOS) are common dietary oligosaccharides that are allowed on the SCD. FOS are found in foods such as onions, garlic, leeks, certain beans, and cashews, which are permissible on the SCD. While FOS cannot be broken down by human enzymes, leading to malabsorption, they are allowed on the SCD because they are not hard-to-digest carbohydrates.
Oligosaccharides like FOS are highly fermentable fibres, which can lead to gas production, bloating, abdominal pain, and excessive flatulence in sensitive individuals. However, the SCD is designed to eliminate carbohydrates that are fermented by microbes in the intestines, not those that are fermented in the colon, like FOS.
The SCD allows monosaccharides, which are simple carbohydrates that are easily absorbed by the intestine wall. Monosaccharides include glucose, fructose, and galactose, which are found in fruits, vegetables, and some legumes. These foods are allowed on the SCD because they are easily digestible and do not promote the overgrowth of harmful bacteria in the intestines.
While FOS are allowed on the SCD, it is important to note that the diet restricts large groups of nutrient-dense foods, including whole grains, some legumes, and most dairy. As a result, eliminating these foods without replacing their key nutrients could lead to nutritional deficiencies. Therefore, it is recommended to consult with a registered dietitian or qualified healthcare professional before starting the SCD to ensure that nutritional needs are met.

Fructooligosaccharides are found in onions, garlic, leeks, beans and cashews
The Specific Carbohydrate Diet (SCD) eliminates hard-to-digest carbohydrates from a person's diet. This diet is intended to ease the symptoms of digestive disorders like inflammatory bowel disease (IBD). People who follow the SCD diet avoid grains and grain products, as well as foods containing disaccharides and polysaccharides. However, foods containing monosaccharides are allowed.
Fructooligosaccharides (FOS) are a form of carbohydrate called oligosaccharides. They are composed of short fructose chains and occur naturally in many plants, including onions, garlic, leeks, certain beans, and cashews. FOS are also found in other plants such as blue agave, yacon root, chicory root, Jerusalem artichokes, asparagus, bananas, and more.
FOS are subtly sweet and low-calorie, making them a popular alternative sweetener to sugar. They are non-digestible and do not affect blood sugar levels, which can help prevent weight gain. However, FOS can cause side effects such as cramps, nausea, and bloating, especially when overused.
While FOS are allowed on the SCD diet, they can lead to gas production, bloating, abdominal pain, and excessive flatulence in sensitive individuals. This is because FOS, like other oligosaccharides, cannot be broken down by human enzymes and are therefore malabsorbed.

The SCD diet is restrictive and grain-free, allowing some carbs and banning others
The Specific Carbohydrate Diet (SCD) is a restrictive, grain-free diet designed to help manage gastrointestinal conditions such as Crohn's disease, ulcerative colitis, and celiac disease. It is also known to be used by people with irritable bowel syndrome (IBS) and autism spectrum disorder (ASD). The diet allows some carbs and bans others based on how hard they are to digest. The SCD diet eliminates sugars and hard-to-digest carbohydrates like grains and grain products, including bread, pasta, and cereal. It is important to note that the diet may lead to malnutrition and unhealthy weight loss, so it is recommended to consult with a healthcare professional or dietitian before starting.
The SCD diet allows for easily digestible foods like fresh fruits, most vegetables, unprocessed meats, and homemade yogurt. It is important to note that only homemade yogurt that has been fermented for at least 24 hours is allowed on the SCD diet. This yogurt can be made from cow, goat, coconut, or nut milk. The diet also allows for all-natural peanut butter, although other natural nut butters may be better tolerated during the initial stages.
The SCD diet bans starches, grains, processed foods, and lactose-heavy dairy. It is important to note that the diet eliminates large groups of nutrient-dense foods, including whole grains, some legumes, and most dairy. As a result, it is crucial to ensure that key nutrients are replaced to avoid nutritional deficiencies. The diet also bans any food or additive containing two or more chemically linked sugar molecules, known as complex carbs. This includes disaccharides, oligosaccharides, and polysaccharides.
While the SCD diet is restrictive, it can be balanced, complete, and healthy when well planned. It is important to consult with a registered dietitian or qualified healthcare professional to ensure that nutritional needs are being met. The diet may be followed for life, or some people may reintroduce banned foods after a year or once symptoms subside. The decision to reintroduce certain foods should be made in consultation with a healthcare professional.

The diet eliminates sugars and hard-to-digest carbohydrates like grains and starches
The Specific Carbohydrate Diet (SCD) is a restrictive, grain-free diet. It was developed by US paediatrician Dr Sidney Haas in the 1920s to help children with celiac disease, a digestive and autoimmune disease that can cause diarrhoea, bloating, gas and weight loss. The diet has since been used to help people with other conditions, including Crohn's disease, ulcerative colitis, diverticulitis, cystic fibrosis, and chronic diarrhoea.
SCD eliminates sugars and hard-to-digest carbohydrates like grains and starches. It allows easily digestible foods like fresh fruits, most vegetables, unprocessed meats, and homemade yoghurt. The diet aims to reduce harmful gut bacteria by removing hard-to-digest carbs. Carbohydrates can be described by the complexity of their chemical structures – the number of connected "sugar" or starch units. Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. Disaccharides are slightly more complex, consisting of two sugar units chemically bound together. Polysaccharides are even more complex, with multiple sugar or starch units bound together. While monosaccharides are allowed on the SCD, not all are innocuous. Fructose is a monosaccharide found in many fruits, honey, and some vegetables, all of which are permissible on the SCD. However, when present in higher concentrations, fructose can cause an osmotic effect, drawing water into the bowels.
The diet is intended to be followed for one year during active disease flare-ups and another year once symptoms resolve. During the reintroduction phase, one "illegal" food per week can be tried. However, if symptoms occur, it is recommended to return to eating only from the "legal" food list.
The SCD may put people at risk for malnutrition and unhealthy weight loss, so it is important to consult a healthcare provider before starting this diet.

The diet is designed to help people with Crohn's disease, ulcerative colitis and celiac disease
The Specific Carbohydrate Diet (SCD) is a restrictive, grain-free diet designed to help manage gastrointestinal conditions such as Crohn's disease, ulcerative colitis, and celiac disease. The diet allows easily digestible foods like fresh fruits, most vegetables, unprocessed meats, and homemade yoghurt, while banning grains, starches, processed foods, and lactose-heavy dairy.
The SCD aims to reduce harmful gut bacteria by removing hard-to-digest carbs. It was originally created to manage celiac disease, limiting the use of complex carbohydrates (disaccharides and polysaccharides) while allowing monosaccharides. The diet is gluten-free since no grains are permitted.
SCD has been found to ease the symptoms of inflammatory bowel disease (IBD) and other digestive disorders. It eliminates sugars and hard-to-digest carbohydrates like grains and grain products, which can be challenging to cut out. The diet may also put individuals at risk of malnutrition and unhealthy weight loss, so it is important to consult a healthcare provider before starting.
Several small studies have shown that SCD can improve symptoms in children with IBD, and a 2017 review found preliminary evidence that it may help adults with IBD as well. The diet has also been advocated for treating Crohn's disease, with a 2017 review of research finding that it shows promise as a nutritional treatment for both adults and children.
