), Wang, L.H., Hartman, P.A. Lactose intolerance can usually be diagnosed with a careful history supported by dietary challenge. Gastroenterology. This type of deficiency cannot be prevented. 2010. pp. In experimentally induced diarrhea a fecal pH of <5.3 indicates carbohydrate malabsorption is the major cause of diarrhea. Typically these cases will manifest symptoms of pain or diarrhea during the test but are without a rise in breath hydrogen or methane levels. The presence of abdominal pain or diarrhea during the test is supportive evidence for a positive test. Gradual reintroduction of disaccharides, one by one, should determine exactly which disaccharide is not tolerated. If so, which ones? This is called a primary deficiency. Table sugar (white sugar, demarara sugar, brown sugar, icing sugart, etc.) vol. 0000028403 00000 n A coordinator will follow up to see if Mayo Clinic is right for you. Primary causes of disaccharidase deficiencies cannot be prevented. The Meta- bolic Basis of Inherited Disease. Your use of this website constitutes acceptance of Haymarket Medias Privacy Policy and Terms & Conditions. The important thing is to determine a persons capacity to handle the sugar. First, chew foods containing starch for a long period of time. A registered dietitian can assist you in using a food log and determining food tolerances. Yogurt may be tolerated by lactase-deficient individuals and provides a good source of calcium. Of all the disaccharidases measured . He was started on Prednisone 40 mg (20mg BID) and Apriso on Tuesday (they had him take the first does of Prednisone Monday eve) and Wednesday he started feeling so much better. They are hoping to keep him on Prednisone for a while and then taper off of it, then hopefully the Apriso is able to maintain the inflammation. These individuals would most likely have normal levels of maltase and isomaltase (palatinase) activity. Watery diarrhoea or loose stool results from this increase in fluid in the bowel.3 Gases are produced as a result of an increase in microbial growth and fermentation. Begin with a complete diary elimination diet that will help you avoid lactose, the sugar and also whey and casein the proteins. The genetically programmed down-regulation of lactase in children. Diarrhea may be severe enough to purge other nutrients before they can be absorbed. Symptoms and signs of carbohydrate intolerance are similar in all disaccharidase deficiencies. What caused this disease to develop at this time? Starches are typically found in grains such as wheat, potatoes, corn, and rice. Implementation of a lactose-free diet with lactose-free formula or lactase-treated breastmilk leads to rapid recovery. The diet should include salmon, baked beans, spinach, leafy vegetables, shrimp, green peas, oysters, broccoli and fresh fruits. In addition, complete elimination of lactose products can lead to inadequate calcium intake. Infant formulas that are lactose free and sucrose free can be given to a disaccharidase-deficient infant. Classic disaccharidases small bowel biopsy results associated with congenital sucrase-isomaltase deficiency (CSID) are as follows: Your or your childs levels of enzyme activity may differ from the list above, since there are individual differences in the severity of CSID and the degree to which each individual has problems digesting starches. Most affected patients have an increase in expired hydrogen of > 20 parts per million over baseline. Nuts and nut butters can be a great source of calories for you. Carbohydrate malabsorption occurs when the main dietary carbohydrates, sugars and starches, are not absorbed from the gastrointestinal (GI) tract. Sweetened sodas should only be tried under the advice of a registered dietitian or physician. All labs and stool samples came back normal. His lactase is now zero, all of the other ones are very low as well. Other acquired diseases are rotavirus enteritis, giardia infestation, eosinophilic gastroenteritis, Crohns disease, small intestinal bacterial overgrowth, tropical sprue, post-infectious gastroenteropathy, autoimmune enteropathy and pancreatic insufficiency. Irritable Bowel Syndrome and Gastrointestinal Function. Lindquist B, Meeuwisse G. Diets in disaccharidase deficiency and defective monosaccharide absorption. Has he started being treated for Crohns as well? The condition is very rare, with 42 cases of CLD reported between 1966 and 1998 in Finland8. If the deficiency is a result of an inherited tendency, it is likely that the intolerance will be lifelong. Congenital lactase deficiency is extremely rare I will look into the things you mentioned, I appreciate your help. ), (Genetically programmed down-regulation of the lactase gene is detectable in children from the second year of life, although the onset and extent are somewhat variable. (The molecular difference between lactase persistence and nonpersistence is caused by the mutation at position -13910), Lebenthal, E., Khin Maung, U., Zheng, B. Y., Lu, R. B., Lerner, A. The lactose composition of her milk will remain constant, regardless of whether she consumes milk and dairy products. Symptoms typically require ingestion of more than the equivalent of 250 to 375 mL (8 to 12 oz) of milk. 1230-6. Second, combine a high-starch food with a fatty food at the time of ingestion. The advantage of this test is it reflects the absorptive capacity of the entire small intestine for the substrate used. We ended up getting a second opinion as we felt that we werent getting anywhere. Disaccharidase deficiency. vol. The link you have selected will take you to a third-party website. High-fat foods slow the rate food moves through the small intestine. You are encouraged to report negative side effects of prescription drugs to the FDA.

The Health Professionals Guide to Food Allergies and Intolerances by Dr Janice Joneja, published by Academy of Nutrition and Dietetics and available here on Amazon. Because the test is invasive, many people prefer to try to control the symptoms by dietary methods. He was treated with Albendazole and Flagy and for almost 2 months was symptom free with normal bowel movements. Bacterial fermentation of carbohydrates in the colon produces gases (hydrogen, carbon dioxide, and methane), resulting in excessive flatus, bloating and distention, and abdominal pain. Maltose is the disaccharide which results when the starches in grains and starchy vegetables are digested. ), (The molecular difference between lactase persistence and nonpersistence is caused by the mutation at position -13910), (Intestinal glucoamylase deficiency can be the cause of chronic diarrhea. The most common symptoms of disaccharidase deficiencies include abdominal pain, bloating, and flatulence. If there is a deficiency in the enzymes that split these linkages, free glucose molecules will not be released and absorbed, and the remaining undigested starch or sugar will be pass into the large bowel where bacteria ferment it. 10. Two conflicting models describe sucrase and lactase deficiencies. o [ abdominal pain pediatric ] %PDF-1.7 % Most affected children are better able to tolerate sucrose and maltose as they get older. *He was started yesterday on Flagyl. [ PubMed] [ Google Scholar] McGill DB, Newcomer AD. Epidemiological data demonstrate this condition is more common in certain ethnic groups and geographic locations. Copyright 2023 Merck & Co., Inc., Rahway, NJ, USA and its affiliates. Once he had to taper off the predisone, symptoms came back. Gut. Sugars include monosaccharides (glucose, galactose, fructose) and disaccharides (lactose, sucrose, maltose). 0000013437 00000 n Gudmand-Hoyer E, Fenger HJ, Kern-Hansen P, Madsen PR. Transient secondary disaccharidase deficiency may be caused by mucosal damage, such as from acute viral enteritis. Diagnosis is clinical and by small-bowel biopsy. Treatment is removal of the causative disaccharide from the diet. An affected adult may have watery diarrhea, bloating, excessive flatus, nausea, borborygmi, and abdominal cramps after ingesting lactose. If you have CSID, you should plan your diet in conjunction with your physician and registered dietitian. A breastfed baby will ingest significant quantities of lactose in the mothers milk. Maltase: Abnormal Range is less than 100 U* Carbohydrate malabsorption. If you are able to confirm that the patient has disaccharidase deficiency, what treatment should be initiated? They are trying to figure out what the cause of this damage to the duodenom and the dissacharidase deficiency. 0000030173 00000 n 0000019174 00000 n My son is 14 and has had severe GI symptoms for over a year. *Our current doctor is addressing the low Disaccharidase levels, it was the first GI doctor that never really addressed them. 125. Visit www.FDA.gov/medwatch or call 1-800-FDA-1088. After doing bit of research, heres what I found: Disaccharidases are enzymes that break down complex sugars (like lactose) into simple sugars (like glucose) so that the intestine can absorb the nutrients. *The GI doctor doesnt think it is Crohns but is not ruling it out. Lactase levels are high in neonates, permitting digestion of milk; in most ethnic groups (80% of blacks and Hispanics, > 90% of Asians), the levels decrease in the post-weaning period rendering older children and adults unable to digest significant amounts of lactose. 5th edition. Trehalase deficiency is less common and presents when mushrooms are ingested. CancerTherapyAdvisor.com is a free online resource that offers oncology healthcare professionals a comprehensive knowledge base of practical oncology information and clinical tools to assist in making the right decisions for their patients. ), (Patients with congenital sucrase-isomaltase deficiency who consume sucrose can ameliorate the malabsorption by subsequently ingesting a small amount of viable yeast cells, preferably on a full stomach. 124. It occurs in the whey (liquid) part of milk. The trusted provider of medical information since 1899, Small Intestinal Bacterial Overgrowth (SIBO), Last review/revision Feb 2021 | Modified Sep 2022. If the babys lactose intolerance is secondary, as a result of a gastrointestinal tract infection or other transient condition, most specialists advise continuing breastfeeding and as the diarrhoea will gradually diminish as the underlying inflammation disappears. 2004;20(2):162-167. While limiting disaccharide carbohydrates in your diet may seem difficult, there are a variety of foods you can still enjoy. A deficiency of sucrase results in inadequate breakdown of sucrose, which moves into the large bowel and provides an excellent substrate for microbial fermentation, resulting in the symptoms described above. trailer Exclude any processed foods from your diet that have added sucrose. For example, it is suggested that you chew a bite of the food item 30 times before swallowing. For lactase deficiency, 1-2 capsules taken with milk or dairy products; pre-treat milk with 1-2 capsules/quart of milk; Liquid: 5-15 drops/quart of milk; Tablet: 1-3 tablets with meals. Disaccharidases are enzymes that break down complex sugars (like lactose) into simple sugars (like glucose) so that the intestine can absorb the nutrients. 1998. pp. 0000015495 00000 n Symptoms include diarrhea, abdominal distention, and flatulence. Sucrose digestion is a problem for most individuals with CSID. Following an overnight fast and a basal collection of exhaled breath, the test substrate is ingested. Connect with thousands of patients and caregivers for support and answers. Contents Front Matter Section 1 Patients and their treatment Section 2 Background to medicine Section 3 Cell biology Section 4 Immunological mechanisms In cases where mucosal recovery is possible following treatment of the underlying cause (e.g., celiac disease) complete symptom resolution can be anticipated and eventually it should be possible to resume ingestion of all disaccharidases. Disaccharidase Deficiency. Lactose restricted: calcium and vitamin D She holds a master's degree in food science and human nutrition and is a certified instructor through the NRA. Most individuals with CSID can tolerate tofu. In general, if an individual is consuming a wide range of the allowed foods and the condition is a secondary (temporary) deficiency, nutritional supplements should not be necessary. Classic disaccharidases small bowel biopsy results associated with congenital sucrase-isomaltase deficiency (CSID) are as follows: Decreased (usually absent) sucrase activity Decreased-to-normal isomaltase ( palatinase) activity Reduced maltase activity Decreased-to-normal lactase activity A deficiency of these enzymes in the duodenum (small intestine) results in a range of gastrointestinal symptoms. 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. Disaccharide deficiency (usually of lactase) can be acquired or, rarely, congenital. Some individuals with CSID are able to tolerate normal amounts of dietary starch, some can eat limited amounts of starch, and some cannot tolerate any dietary starch. Previously he never had any stomach issues, not even the stomach flu as a kid. A less common but still frequent symptom is diarrhea. It is recommended that you avoid processed cheeses or cheese products since many of these food items contain sucrose or starch fillers. The most common form of lactose deficiency is primary (adult-type) hypolactasia characterized by a decline in lactase activity starting after about 3 years of age. The increase in speed with which food passes through the digestive tract results in inadequate enzymatic breakdown (digestion) of the food, thus increasing the amount of substrate available for microbial fermentation in the large bowel. 0000032824 00000 n These enzymes are localized in the brush border membrane of the small intestinal epithelial cells. vol. Youve read {{metering-count}} of {{metering-total}} articles this month.

Interested in more discussions like this? If you have tried dairy elimination, your next option is to remove all refined and added sugar from your diet. In infants, temporary secondary disaccharidase deficiency may complicate enteric infections or abdominal surgery. Learn more about the Merck Manuals and our commitment to Global Medical Knowledge. Development of symptoms (particularly diarrhoea) over the following 24 hours should indicate the culprit disaccharide. The sugars remaining unabsorbed move into the large bowel and are fermented Strong drugs and antibiotics 5. For symptomatic patients wishing to drink milk, lactose in milk can be predigested by the addition of a commercially prepared lactase, and pretreated milk is now available. When you are figuring out a CSID diet, its imperative to keep a food log or food diary. 7. You can also enjoy a variety of vegetables such as asparagus, salad greens, eggplant, peppers and onions. An intolerance to disaccharides (two sugars (saccharides) bound together), of which the best known is lactose intolerance, is caused by an impairment to the breakdown and absorption of certain sugars. The most important disaccharidase in the newborn period is lactase. The disaccharides activity panel examines tissue samples, which have been taken as part of endoscopy, to gain quantitative values of lactase, sucrase, maltase, palatinase, and glucoamylase. The most frequent cause of mucosal damage is celiac disease that can affect 1% of the population. Diarrhoea, abdominal distention, pain, and flatulence (wind) are the usual symptoms of disaccharide intolerance.2 , These symptoms are the result of microbial fermention and a change in osmotic pressure in the large bowel. No doctor in USA believes Crohns can be liver related disorder. There is no significant risk associated with enzyme replacement therapy. When introducing new food items, it is recommended that you wait at least three days before introducing an additional food item. 2004. pp. 2009;125(7):766-770. A serving size or more of each of the relevant food types (see below) should be consumed. This increases the amount of fermentation products in the colon, which perpetuates the cycle. Congenital sucrase-isomaltase deficiency presenting Most individuals with CSID can eat dairy products such as cows milk, ricotta cheese, plain cottage cheese, sour cream, butter, cream, whipping cream, and hard cheeses like cheddar, Colby, mozzarella, Swiss, parmesan, and provolone. 1966 Apr;48(4):307-310. ApH of >5.6 suggests carbohydrate malabsorption is not the only cause of diarrhea. The smallest carbohydrate units, the monosaccharides, are the building blocks for more complex sugars and starches. When starting a CSID-friendly diet, it is recommended that you consume no grain-based starches at all. 0000026875 00000 n pitfalls and approach to management. 0000044848 00000 n Finally, the last two joined glucose molecules become maltose. The starch content of fruits and vegetables is an important variable to consider when introducing dietary starches. Serum glucose is measured before ingestion and 60 and 120 minutes after. It seems like from the research I have done on it says it is caused from either an infection, inflammatory bowel or Crohns. My sons symptom have become spending most of the day in the bathroom pooping soft serve, lots of mucus- sometimes it is bloody. In addition milk products which are easier to digest may be consumed which include soy milk, butter milk, lactose free milk, goat's milk, etc Disaccharidase Deficiency Treatment Sucraid(sacrosidase) Oral Solution is an enzyme replacement therapy for the treatment of genetically determined sucrase deficiency, which is part of congenital sucrase-isomaltase deficiency (CSID). Use to remove results with certain terms For this reason, it is recommended that you monitor consumption of these vegetables closely. in Infancy. Journal of the American Dietetic Association Volume 48, Issue 4, April 1966, Pages 307-310 Diets in Disaccharidase Deficiency and Defective Monosaccharide Absorption Diets in Disaccharidase Deficiency and Defective Monosaccharide Absorption1 Bertil Lindquist 1 , Gunnar Meeuwisse https://doi.org/10.1016/S0002-8223 (21)20467-7 Get rights and content I appreciate any information you find! The outcome in cases of secondary disaccharidase deficiencies is dependent on the underlying cause of the intestinal mucosal damage. Primary causes are trehalase deficiency, maltase-glucoamylase deficiency, sucrase-isomaltase deficiency, sucrase-isomaltase deficiency which is onset from birth and related to sucrose or starch intake, primary adult type hypolactasia which is onset from 3 years up to early adulthood, and the rarely case of congenital lactase deficiency. (Yogurt a well-tolerated source of milk for lactase-deficient persons. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. Indication Sucraid (sacrosidase) Oral Solution is an enzyme replacement therapy for the treatment of genetically determined sucrase deficiency, which is part of Congenital Sucrase-Isomaltase Deficiency (CSID). Most cases are infectious, although gastroenteritis may occur after ingestion of drugs and chemical read more ]). Conditions that may trigger a disaccharide intolerance, Intolerance may occur as a result of any condition that causes a decrease in disaccharide enzyme activity:5. The enzyme that breaks down sucrose, sucrose alpha-glucosidase, or sucrase, splits sucrose into the two monosaccharides or single sugars: glucose and fructose. <<06E783B5A772D64DBD765FF42D03F1F7>]/Prev 398468/XRefStm 1706>> PMID: 4554577 No abstract available. Congenital deficiencies of disaccharidases and the primary lactase deficiency are due to genetic variations. It is also detected by testing the stool for glucose or other sugars like sucrose and starches. fraction of milk and other dairy products. When beginning a diet, you could start with the food items that most individuals with CSID can tolerate and then add other food items over time, as tolerated. Even though it might be difficult to find registered dietitians who have experience with CSID, they will be able to demonstrate how to effectively write and manage a food log or diary and how to add foods by trial to the diet. Rats were assigned to zinc deficient (ZD), control (C) or pair-fed (PF ) groups and fed for 40 d a zinc deficient (1 mg/kg) diet (ZD rats) or a similar diet supplemented with 50 mg Zn/kg (C and PF rats).

A genetic test which can be used to diagnose adult-type hypolactasia in children. 0 2003. pp. Unless additional calcium is obtained from other food sources or supplements there is potential risk for decreased bone density. Go to the Digestive Health Support Group. Undigested disaccharides cause an osmotic load that attracts water and electrolytes into the bowel, causing watery diarrhea. This results in abdominal bloating, pain, and flatulence (wind). Identifying an often overlooked diagnosis, Advanced testing to pinpoint disaccharidase deficiency. 1988;112(5):709-713. (Genetically programmed down-regulation of the lactase gene is detectable in children from the second year of life, although the onset and extent are somewhat variable. These test results should be correlated with symptoms for assessment of lactose intolerance; a few standardized questionnaires are currently being validated. Lactose-intolerant patients must take calcium supplements (1200 to 1500 mg/day). Usually the intestinal cells are producing a limited amount of enzyme, so that small doses of disaccharides in foods can be processed. In all cases of disaccharidase deficiency, symptoms are confined to the digestive tract. In the typical American diet, 60% of the total calories consumed originate from carbohydrates. Sucrose tolerance levels may be determined by introducing increasing amounts of sugar-containing foods slowly, combined with Sucraid (sacrosidase) Oral Solution to help limit gastrointestinal symptoms. . 0000011518 00000 n Kolars, J. C., Levitt, M. D., Aouji, M., Savaiano, D. A.. Yogurt an autodigesting source of lactose. However, protein sources such as meats may be cooked with butter, oils, salt, and pepper without triggering CSID-like symptoms. CSID is an inherited deficiency of the ability to hydrolyze sucrose, maltose, and starch. However, gold . 0000021870 00000 n In the hydrogen breath test, 50 g of lactose is given orally and the hydrogen produced by bacterial metabolism of undigested lactose is measured with a breath meter at 2, 3, and 4 hours postingestion. It is unclear why the normal state of > 75% of the worlds population should be labeled a deficiency.. Thank you for the information. 0000025466 00000 n Maltose tolerance is determined by consuming starch in the form of white grains and flours white bread, white rice etc. A child who cannot tolerate lactose develops diarrhea after ingesting significant amounts of milk and may not gain weight. Lactase deficiency has been observed in 30% to 40% of patients with Crohn's disease. Gastroenterology. 2. Be assured that over time and by paying close attention to specific foods and related symptoms, the list of acceptable foods grows substantially. Lactose tolerance is determined by consuming complete milk and dairy products containing complete milk. ), (Genetic test of C/T(-13910) polymorphism can be used as a first stage screening test for adult-type, Close more info about Disaccharidase Deficiencies, OVERVIEW: What every practitioner needs to know. 1867 44 Because the small intestine and large intestine are getting smaller amounts of starch at any given time, you may be better able to tolerate the dietary starch. 0000037251 00000 n The diagnosis of lactose intolerance is also suggested if the stool from chronic or intermittent diarrhea is acidic (pH < 6) and can be confirmed by a hydrogen breath test or a lactose tolerance test that indicates malabsorption. Intestinal mucosal damage associated with many diseases results in secondary disaccharidase deficiencies. Working with a registered dietitian is crucial to dietary success. Starchy foods break down more easily if exposed to salivary amylase in the mouth for an extended period. Here is a one-day sample CSID diet menu that is low in sucrose and starch: Breakfast: spinach omelet, blueberries, and milk Snack: plain Greek yogurt sweetened with dextrose and topped with sliced strawberries Lunch: no-noodle lasagna with a tossed salad Snack: cottage cheese and grapes Dinner: grilled pork chop, steamed broccoli, and cherries Infections in the digestive tract with parasites such as amoebae, helminths, nematodes, microorganisms such as Giardia lamblia, and viruses such as the rotavirus group Whole-wheat pasta, quinoa, lentils, brown rice, or wild rice are better options than more processed grains such as white rice. Home Decision Support in Medicine Pediatrics. The monosaccharides are then absorbed through the gut wall, into blood. Disaccharidase deficiency | Oxford Textbook of Medicine | Oxford Academic Skip to Main Content Subject Journals Books Oxford Textbook of Medicine (6 edn) John Firth (ed.) ease than previously thought? Im so sorry to hear about your son; it must be terrible to watch him go through all this. It has been noted that some individuals with CSID are able to increase their starch tolerance as they age and their digestive tract grows longer. Carbohydrate intolerance is the inability to digest certain carbohydrates due to a lack of one or more intestinal enzymes. You can use the food composition tables on this website to determine the starch levels in food items. Once it is determined how much dietary sucrose you can tolerate, with and without Sucraid, starches can be added to the diet slowly, watching carefully for gastrointestinal symptoms. Use of rotavirus vaccine has been shown to significantly decrease the occurrence of disease and this in turn will decrease the incidence of acquired disaccharidase deficiency. Thus, combining a high-fat food with a starch increases the time the foods remain in the small intestine and allow the starch to have more exposure to pancreatic amylase, isomaltase, and maltase in the small intestine. The most common form of disaccharidase disorder is lactase deficiency, when . Food allergy affecting the digestive tract Patients with disaccharidases deficiencies in the duodenum can experience intolerances to foods containing complex sugars, resulting in a range of gastrointestinal symptoms including diarrhea, constipation, abdominal pain and cramping, gas, bloating, and nausea. In determining your capacity to digest various fruits and vegetables, they can consult the food composition tables to determine acceptable food items within your sucrose and starch dietary limits. However, this is a non specific finding and hence imaging studies have no role in the diagnosis of disaccharidase deficiencies. However, because the degree of lactose malabsorption varies greatly, many . Sucraid (sacrosidase) Oral Solution is an enzyme replacement therapy for the treatment of genetically determined sucrase deficiency, which is part of Congenital Sucrase-Isomaltase Deficiency (CSID). You should also avoid processed meats such as bacon, sausage, luncheon meat, deli meat, liverwurst, and pt since many of these food items are cured with sucrose or have starch fillers. How do these pathogens/genes/exposures cause the disease? PPTwordPPTwordwordword They tried some antispasm medication that did nothing. How should you interpret the results? When looking at the list above, it may appear to be a very short list of foods someone with CSID can eat. jQuery("#quest").attr("href", f + g); Sucrase-isomaltase deficiency is the second most common disaccharidase deficiency. 0000018465 00000 n This enzyme complex (sucrase-isomaltase) assists in the breakdown of a certain sugars (i.e., sucrose) and certain products of starch digestion (dextrins). Treatment read more , acute intestinal infections [see Gastroenteritis Overview of Gastroenteritis Gastroenteritis is inflammation of the lining of the stomach and small and large intestines. Maldigestion of carbohydrates. The carbohydrate content of the normal western diet is about 60% starch, 30% sucrose, and 10% lactose, and each of those is digested differently.1, Lactose is the sugar in milk. Algorithm for the diagnosis of the most frequent disaccharidase deficiency: lactose malabsorption. Drugs, inflammatory diseases and pathogens can cause direct damage to the enterocytes or adversely affect cell turnover in the small intestine. While limiting disaccharide carbohydrates in your diet may seem difficult, there are a variety of foods you can still enjoy. So the undigested lactose moves into the colon, where it provides an excellent base for microbial fermentation. Breakfast cereals or grains that contain whole oats, barley, or bran are better options than more-processed, refined cereals. CARBOHYDRATES provide a substantial proportion of the total caloric content of our diet.
