Celiac.com 04/15/2023 - Celiac disease is a chronic autoimmune disorder that affects the small intestine, triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. One often overlooked consequence of untreated and undiagnosed celiac disease is the potential for nutrient deficiencies. Due to the damage caused to the lining of the small intestine, absorption of various essential nutrients may be impaired, leading to deficiencies that can have wide-ranging health effects. In this article, we will explore the connection between celiac disease and nutrient deficiencies, focusing on several key vitamins, minerals, and other essential nutrients. The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium. Celiac disease can disrupt the absorption of these essential nutrients, potentially leading to anemia, bone health issues, and other health complications. After a celiac disease diagnosis it is important to do follow up testing for these nutrient deficiencies, as well as a follow-up endoscopies/biopsies to make sure that a patient's damaged villi are healing properly. Many of those with celiac disease will need to take vitamin and mineral supplements at the time of their diagnosis, and some will need to continue taking them for life. Note that having nutrient deficiencies alone would not be enough for a definitive diagnosis of celiac disease, and further testing is required to make a formal diagnosis. Boron Boron is a trace mineral that plays a role in bone health, brain function, and metabolism of certain nutrients. Deficiency in boron is rare, but it can lead to symptoms such as muscle weakness, joint pain, and impaired cognitive function. Untreated and undiagnosed celiac disease can cause malabsorption of boron due to damage to the small intestine lining, potentially leading to a deficiency. Supplementation of boron may be needed for individuals with celiac disease, especially if they have prolonged untreated celiac disease or other risk factors for deficiency. Calcium Calcium is an essential mineral that is crucial for bone health, nerve function, and muscle contraction. Deficiency in calcium can lead to symptoms such as weakened bones, muscle cramps, and numbness and tingling in the extremities. Malabsorption of calcium can occur in celiac disease due to damage to the small intestine lining, potentially leading to a deficiency. This can further increase the risk of osteoporosis and other bone-related complications in individuals with celiac disease. Measuring blood levels of calcium alone is not always an accurate indicator of calcium deficiency because the body will leach calcium from the bones to maintain normal blood levels of calcium. Therefore, bone density loss and other secondary indicators are often better diagnostic tools for detecting calcium deficiency. Calcium supplementation, along with a calcium-rich diet, may be necessary for individuals with celiac disease to maintain adequate calcium levels and support bone health. Chloride Chloride is an electrolyte that is involved in maintaining proper fluid balance, nerve function, and acid-base balance in the body.

Celiac.com 04/29/2024 - Getting enough calcium in the diet is essential for people of all ages, as this mineral performs many important functions in the body. In addition to bone health, calcium is required for muscle contractions, nerve impulses, normal blood clotting and regulating blood pressure. It may also offer protection from colon cancer. Children and adults with celiac disease need to pay particular attention to calcium and other nutrients as many already have or will develop early bone disease such as osteopenia or osteoporosis. Osteopenia is low bone mineral density and osteoporosis is characterized by a significant decrease in bone mass resulting in brittle, easily broken bones. The hip, spine and wrist are most susceptible to fracture. Early diagnosis and treatment of celiac disease is critical for the prevention of bone disease. To maintain good bone health it is important that all people with celiac disease have routine bone density tests done to assess their overall bone health, and to follow the tips outlined below. Follow a strict gluten-free diet Healthy villi will result in normal absorption of nutrients. Meet your daily calcium requirements Table 1: Dietary Reference Intake for Calcium /* DivTable.com */ .divTable{ display: table; width: 100%; } .divTableRow { display: table-row; } .divTableHeading { background-color: #EEE; display: table-header-group; } .divTableCell, .divTableHead { border: 1px solid #999999; display: table-cell; padding: 3px 10px; } .divTableHeading { background-color: #EEE; display: table-header-group; font-weight: bold; } .divTableFoot { background-color: #EEE; display: table-footer-group; font-weight: bold; } .divTableBody { display: table-row-group; } Age Calcium (mg/day) Infants 0- 6 months 7-12 months 210 270 Children 1-3 years 4-8 years 500 800 Females and Males 9-13 14-18 19-30 31-50 51-70 71 + 1300 1300 1000 1000 1200 1200 Choose calcium-rich foods See Table 2 for a list of gluten-free foods. Remember that not all calcium sources are created equal. Milk (fl uid, powdered or evaporated) and milk products such as cheese and yogurt contain the most readily available source of calcium. Other foods such as salmon and sardines with the bones, calcium-fortifi ed beverages (soy, rice and orange juice), tofu made with calcium sulfate and vegetables (broccoli, collards, kale, mustard greens, turnip greens and bok choy) also contain calcium that is easily absorbed by the body. However, the calcium found in almonds, sesame seeds, dried beans and spinach are absorbed less effi ciently because these foods contain calcium-binding substances called oxalates. Although the calcium content of these foods should not be counted as part of your daily calcium intake; they do provide many other nutrients important for good health.

Calcium content can vary greatly from one brand to another and can be low. Tofu processed with magnesium chloride also contains less calcium. Consider calcium supplementation If you are unable to consume enough dietary calcium you many to need a gluten-free calcium supplement. Look for the amount of “elemental calcium” on the label. Your body can only absorb 500 mg at one time therefore it is best to divide your dose throughout the day. Calcium carbonate is more slowly absorbed and should be consumed with meals. Calcium citrate is well absorbed with meals or an empty stomach. Bone meal or dolomite calcium supplements are not recommended as some products have been found to contain lead and mercury. Limit caffeine intake Studies have shown that caffeine increases calcium loss through the urine. Most experts agree that 2-3 cups of coffee/day is probably not harmful provided that calcium intake is adequate, so limit your coffee and cola intake. Limit sodium intake Sodium also has been shown to increase the loss of calcium through the urine. Therefore it is advisable to limit your intake of processed foods, table salt and salt in cooking. Get enough Vitamin D Vitamin D helps the body use the calcium in food. It can increase calcium absorption by as much as 30-80 %. See Table 3 for the Dietary Reference Intake for vitamin D. The easiest way to get vitamin D is from exposure to sunlight, which causes the body to make its own vitamin D. All you need is 15 minutes per day; however, aging significantly decreases 1) the ability of the skin to produce vitamin D and 2) kidney function that is involved in converting the inactive to active form of vitamin D. Also, sunscreen blocks the production of vitamin D in the skin. Another concern is that between the months of October and March in Canada and the northern USA, vitamin D synthesis in the skin is very limited. To make up for the lack of sunlight look for other sources of vitamin D listed in Table 4, and remember the points below.

Recently some companies have been adding vitamin D to other dairy products so be sure to read the ingredient label and nutrition panel. Fatty fish (sardines, salmon and herring) and cod liver oil and halibut liver oil are high in vitamin D. Many soy and rice beverages are fortified with vitamin D. Check the ingredient list carefully as some products may contain barley malt extract/flavoring and must be avoided. Nut beverages (e.g. Blue Diamond Almond Breeze) and potato beverages (e.g. Vances DariFree) are fortified with vitamin D. Multivitamin supplements usually contain 200-400 IU of vitamin D. Some calcium supplements may contain vitamin D. Amounts vary so check the label.
