Disaccharides, a type of carbohydrate composed of two sugar molecules, are found in many foods. For individuals with certain health conditions or sensitivities, a low disaccharide diet can be a beneficial approach to managing symptoms and improving overall well-being. This article explores the importance of understanding disaccharides, the need for a low disaccharide diet, how to implement it successfully, meal planning, and potential challenges and solutions.
Understanding Disaccharides
Disaccharides are carbohydrates formed when two monosaccharides (simple sugars) join together. The primary disaccharides in our diet are sucrose, lactose, and maltose.
- Sucrose: Commonly known as table sugar, sucrose consists of one glucose molecule and one fructose molecule. It's prevalent in sweet foods and beverages like desserts, sodas, and candies.
- Lactose: Found in milk and dairy products, lactose comprises one glucose molecule and one galactose molecule. It's a crucial energy source for infants, but some individuals lack the enzyme lactase needed to break it down, leading to lactose intolerance.
- Maltose: Primarily derived from grains and cereals, maltose is formed during starch digestion and consists of two glucose molecules. It's present in foods like beer, malted beverages, and some sweeteners.
Disaccharides provide energy, but consuming them in moderation is key. Excessive intake, especially from added sugars, can contribute to weight gain and other health issues.
Sources of Disaccharides in Food
Disaccharides are present in various foods:
- Fruits: Apples (sucrose), oranges (sucrose and fructose). Note: even low-sucrose fruits need to be monitored. You may have a threshold of how much sucrose you can tolerate.
- Dairy: Milk and yogurt (lactose).
- Grains: Bread and pasta (maltose).
- Sweeteners: Table sugar (sucrose), honey (sucrose, fructose, and glucose).
The Need for a Low Disaccharide Diet
A low disaccharide diet may be necessary for individuals with health conditions or symptoms related to disaccharide intolerance. By limiting high-disaccharide foods, individuals can manage symptoms and improve their well-being.

Health Conditions Requiring a Low Disaccharide Diet
- Lactose Intolerance: Deficiency of the enzyme lactase, needed to break down lactose.
- Sucrose Intolerance: Deficiency of the enzyme sucrase, needed to break down sucrose (table sugar). New research finds that over a third of people with IBS and diarrhea may have sucrose intolerance. You do not have enough of the sucrase enzyme to digest sucrose in both congenital and acquired forms.
- Fructose Malabsorption: Inability to properly absorb fructose, a sugar found in fruits, honey, and some vegetables.
- Irritable Bowel Syndrome (IBS): A gastrointestinal disorder with symptoms like abdominal pain, bloating, diarrhea, and constipation. There is overlap between sucrose intolerance symptoms and other GI issues, including fructose malabsorption, lactose intolerance, and other digestive conditions.
Benefits of a Low Disaccharide Diet
- Reduced Digestive Symptoms: Less bloating, gas, diarrhea, and abdominal pain. The Sucrose Intolerance Diet may help relieve gut symptoms.
- Improved Energy Levels: Reduced fermentation in the gut, leading to less fatigue.
- Better Nutrient Absorption: Reduced interference with the absorption of vitamins and minerals.
- Weight Management: Controlled calorie intake by limiting sugary foods.
Implementing a Low Disaccharide Diet
Implementing a low disaccharide diet involves understanding which foods contain disaccharides and finding suitable alternatives. Working with a knowledgeable healthcare practitioner or registered dietitian can make the process easier.
Identifying High Disaccharide Foods to Avoid
Common disaccharides include lactose, sucrose, and maltose. Reading food labels helps identify hidden sources of disaccharides like added sugars or lactose in processed foods, sauces, and condiments. In addition to lactose, other disaccharide-containing foods to avoid or limit include high-fructose corn syrup, honey, agave nectar, and certain fruits such as mangoes and grapes.
Suggested Low Disaccharide Foods
- Lean Proteins: Chicken, fish, and tofu are low in carbohydrates and do not contain disaccharides.
- Non-Starchy Vegetables: Broccoli, spinach, bell peppers, and cauliflower provide vitamins, minerals, and fiber with minimal carbohydrates.
- Certain Grains (in moderation): Quinoa and buckwheat are low disaccharide grains.
- In general, you can consume most fats and oils, such as butter, margarine, olive oil, and vegetable oil, without restriction. In general, individuals with CSID can tolerate milk, water, diet soda, and homemade limeade or lemonade made with fresh juice and sweetened with fructose or dextrose. Some can tolerate regular, non-diet sodas that are sweetened with high fructose corn syrup. In general, most individuals with CSID tolerate salt. Some tolerate pepper and others do not since black pepper does have a small amount of sucrose and some starch. When starting a diet, it is recommended that you use few other spices or seasonings in order to more clearly determine your tolerance levels since many spices contain sugar or starch fillers.
Congenital Sucrase-Isomaltase Deficiency (CSID)
Dietary treatment for Congenital Sucrase-Isomaltase Deficiency (CSID) is based on restricting the consumption of sucrose, isomaltose, and maltose. The degree of restriction required to relieve gastrointestinal symptoms is specific to the individual. When you are figuring out a CSID diet, it’s imperative to keep a food log or food diary. Every item you eat or drink should be recorded, along with the time of ingestion. Recording serving size or weight can also be helpful. Also write down the timing of any gastrointestinal symptoms you experience, such as bloating, gas, diarrhea, or abdominal pain. To first determine your sucrose tolerance levels, it may be necessary to remove all sucrose-containing carbohydrates from your diet. Sucrose, a carbohydrate, is typically table sugar or white sugar, which can be an additive in many prepared foods. There are additional forms of sucrose, and sucrose also occurs naturally in some foods. Sucrose digestion is a problem for most individuals with CSID. You should consult with your physician and registered dietitian to discuss how much starch you can tolerate. If you know your disaccharidase assay results, the finding may be used as an initial indication of starch-digestion capacity, based on your level of maltase-glucoamylase activity.
Meal Planning and Recipes
Planning meals and having a variety of recipes that adhere to a low disaccharide diet is key to maintaining compliance and enjoying a flavorful diet. When following an elimination diet, it is vital to track meals, drinks, and symptoms. Reviewing the data: How are things going? How are you feeling? Have you had any sucrose during the trial? Sugar is added to many foods. If your symptoms are not improving, do a careful examination of the food and drink you are eating. Many people with sucrose intolerance can enjoy some sucrose without feeling symptomatic. They may have enough sucrase enzymes to digest small amounts. Everyone is different. You have to find your “sweet spot,” the amount you can eat without symptoms. Many people are busy and tend to multitask while eating. Slow down and thoroughly chew your food. Digestion starts in the mouth. Chewing and enzymes in your mouth begin the digestive process. If you tolerate starchy foods, focus on whole grains. The fiber slows down transit time and gives your body time to digest the starch.
Challenges and Solutions
Embarking on a low disaccharide diet may present some challenges, but with proper planning and knowledge, these can be overcome.

Overcoming Cravings for High Disaccharide Foods
Find satisfying alternatives like natural sweeteners (stevia) or consuming fruit in moderation. Experiment with different cooking methods and spices to enhance the flavors of low disaccharide meals.
Eating Out on a Low Disaccharide Diet
Communicate dietary needs to servers or hosts. Opt for dishes based on lean proteins and non-starchy vegetables.
Low-FODMAP Diet
FODMAP is an acronym for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. The low-FODMAP diet temporarily restricts these carbohydrates in order to relieve uncomfortable symptoms and give your digestive system a rest. Removing irritants gives your gut lining a chance to repair itself and can help restore a healthy balance of gut flora. If your symptoms improve, you can use the low-FODMAP diet to figure out which foods to limit in the future.
What are FODMAPs?
- Fermentable: Foods that gut bacteria feed on, converting them to gases.
- Oligosaccharides: Soluble plant fibers (prebiotics) that feed beneficial gut bacteria; includes onions, garlic, beans/lentils, and many wheat products.
- Disaccharides: Lactose, the sugar in dairy and breast milk. Lactose intolerance is one of the most common food intolerances worldwide.
- Monosaccharides: Fructose, the sugar in fruit, but only in certain quantities and proportions.
- Polyols: Sugar alcohols, commonly used as artificial sweeteners, also found naturally in some fruits.
Why are FODMAPs Difficult to Digest?
FODMAPs are short-chain carbohydrates that can't be broken down in the small intestine, drawing in extra water. In the large intestine, bacteria ferment them, producing gases and fatty acids.
Who Might Benefit from a Low-FODMAP Diet Plan?
The low-FODMAP diet is often prescribed for limited periods for people diagnosed with irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO). It can also be used as a short-term elimination diet for anyone who has digestive problems and wants to try and isolate the foods that are causing them.

What Does a Low-FODMAP Diet Consist Of?
The diet has three phases: an elimination phase, a reintroduction phase and a maintenance phase that’s customized to you. During the elimination phase, you'll avoid all of the high-FODMAP foods - a list of specific fruits, vegetables, dairy products and grains. After two to four weeks, you’ll begin the reintroduction phase, in which you systematically add foods back in. The third phase keeps what works for you and leaves out what doesn’t.
Foods to Avoid on a Low-FODMAP Diet
- Fruits: apples, applesauce, apricots, blackberries, blueberries, boysenberries, cherries, dates, figs, grapes, nectarines, peaches, pears, plums, raspberries, watermelon
- Sweeteners: agave nectar, fructose, high fructose corn syrup, honey, isomalt, malt extract, maltitol, mannitol, molasses, sorbitol, xylitol
- Vegetables: artichokes, asparagus, beetroot, broccoli, Brussels sprouts, butternut squash, cabbage, cauliflower, fennel, garlic, karela, leeks, mushrooms, okra, onions, peas, shallots
- Dairy products: ice cream, most yogurts, soft and fresh cheeses (cottage cheese, ricotta, etc.), sour cream, whey protein supplements
- Legumes: beans, baked beans, black-eyed peas, broad beans, chickpeas, fava beans, lentils, pinto beans, red kidney beans, soybeans, split peas
- Wheat: biscuits, bread, most breakfast cereals, crackers, pancakes, pasta, tortillas, waffles
- Other grains: amaranth, barley, rye
- Beverages: coconut water, fortified wines, fruit juices, kombucha, oat milk, rum, soft drinks with high fructose corn syrup, soy milk, tea (chai, chamomile, fennel)
Foods to Eat on a Low-FODMAP Diet
- Meats, fish and eggs: Unless they have added high FODMAP ingredients, like wheat or high fructose corn syrup.
- Nuts and seeds: Nuts and seeds that you can eat include peanuts, macadamia nuts, pine nuts, and sesame seeds but not pistachios, almonds, or cashews, which are high in FODMAPs.
- Fruits: Unripe bananas, Cantaloupe, Grapefruit, Kiwi, Lemons, Lime, Mandarins, Melons (except watermelon), Oranges, Passionfruit, Strawberries
- Vegetables: Alfalfa, Bell peppers, Bok choy, Carrots, Celery, Chives, Cucumbers, Eggplant, Ginger, Green beans, Kale, Lettuce, Olive, Parsnips, Potatoes, Radishes, Spinach, Spring onions (only green), Squash, Sweet potatoes, Tomatoes, Turnips, Water chestnuts, Yams, Zucchini
- Grains: Corn, Oats, Quinoa, Rice, Sorghum, Tapioca
- Other foods or ingredients: All fats and oils, Most herbs and spices, Sweeteners (maple syrup and stevia), Dairy products if they are lactose-free as well as hard cheeses and aged softer varieties (like Brie and Camembert)
- Beverages: Water, coffee, green, black, or white tea, etc
Risks of a Restricted Diet
Risks are primarily related to following a restricted diet. That isn’t easy and can create mental stress. Cutting out foods you like is hard. Fruits and vegetables are full of health-promoting vitamins, minerals, phytochemicals, and fibers. Limiting processed foods and drinks with added sugars is healthy. For the genetic form of sucrose intolerance, the diet is lifelong. If sucrose intolerance is due to underlying digestive problems, the underlying issue must be addressed first. Reintroduce one food at a time, slowly increasing the portion size. Make a note of any symptoms., Be sure to write things down so that you can refer back to the information.
