This is a little bit different of a post than normal, but Lori wrote the following article for my website and I thought it might be helpful for some of you-all as well.
CELIAC DISEASE AND NUTRITION
By Lori S. Brizee MS, RD, LD, CSP

When first diagnosed with CD a person is often anemic, under weight and deficient in many vitamins and minerals due to long term malabsorption of nutrients. For a person who has had long-standing, undiagnosed CD, thinning or weak bones is a major and debilitating problem. In the worst case scenario, adults will have osteoporosis and a child will have rickets as well as poor growth in height. Problems with bones and anemia effect people with ‘silent’ CD (CD without diarrhea) as well. Following the gluten free diet while meeting nutrient needs can reverse most if not all of these problems. (1, 2, 3, 4)
An issue for children can be the association of eating with the pain, bloating and diarrhea that they experience before starting the diet. This can cause a dislike or fear of eating, resulting in poor or very ‘picky’ eating; it may take several months of being on the diet and feeling good before a child is willing to eat enough to meet his needs and to accept new foods. Working with an RD and/or therapist who is skilled in ‘feeding problems’ can help parents to promote healthy eating and prevent future eating disorders. Children required to follow special diets are at higher than normal risk for developing eating disorders (e.g. anorexia and/or bulemia) as they enter adolescence (5).
Re-nourishing After Diagnosis of CD:
- Calcium and Vitamin D:
Needs for calcium and vitamin D are high if bone problems have developed before diagnosis of CD. It is very important that everyone with CD meet at least the Dietary Reference Intake (DRI) for Calcium, and two to three times the DRI for Vitamin D. (See table 1 for recommended intake.)
Several, recent research studies have shown that current DRI’s for vitamin D are much too low; it is quite reasonable to increase vitamin D intake to a higher, but safe level to ensure healthy bone development and prevention of many other chronic diseases. However, excess vitamin D is toxic; staying within the DRI’s safe and tolerable upper limit for the vitamin is essential.

- Iron/Anemia:
Iron intake may need to be increased, as iron deficiency anemia is common in people with untreated CD. Anemia is present even in people who have ‘silent CD’. In addition to iron deficiency, the inflammation present with CD may be a cause of anemia. To eliminate this anemia, one needs to strictly follow the gluten free diet. (4)
- Other vitamins and minerals
Other vitamins and minerals are all likely to be deficient if diarrhea has persisted for a long time. It is suggested that a newly diagnosed CD patient take a gluten free multi-vitamin and mineral supplement until he has been symptom free for several months. After that, it is quite possible to meet needs with food.
Nourishing a Person With CD Over the Long Term:
Once on the gluten free diet for several weeks, people who had diarrhea prior to diagnosis usually gain weight well, and children “catch up” in growth in both weight and height. Some people actually become overweight—for the first time in many years they can eat without having pain, AND they are absorbing the nutrients that they eat. Others, especially those with ‘silent’ CD (no gut symptoms or diarrhea) may have a hard time keeping there weight up, due to removing such a huge body of foods from their diets. Just like the rest of the world, a person with CD needs to avoid over OR under-eating. Children can do a good job of self regulating if offered foods in 5 to 6 regular meals and snacks each day. Coaxing children to eat or restricting them because we think they are over-eating can lead to many parent-child battles over food, and even eating disorders.
The gluten free diet must be strictly followed; eating wheat (even with no symptoms) can cause lesions to begin forming in the small intestine and significantly increase the risks of osteoporosis and anemia. (6) This can be a big problem in adolescents who want to fit in with their friends—if they can eat a little wheat here and there without pain or diarrhea, it will be difficult to convince them to stop. They have a hard time believing that problems associated with CD will truly impact them. (5)
What does a Healthy Diet Look Like?
- Fruits and Vegetables:
Including at least 5 servings of vegetables and 3 servings of fruit per day is important for everyone to meet needs for vitamins, fiber, and antioxidants. People who eat lots of fruits and vegetables have lower levels of heart disease, macular degeneration, and many cancers. Fortunately, fresh, frozen, canned and dried, plain fruits and vegetables contain NO gluten, so everyone with CD can eat loads of them. Eating additional starchy vegetables (potatoes, yams, sweet potatoes, winter squashes, parsnips, carrots, peas) helps make up for the removal of many wheat, rye or barley based foods.
- Whole Grains:
Whole corn, brown rice and quinoa are whole grains that can take the place of gluten containing grains and are a great source of vitamins, minerals and fiber. Including these on a regular basis is a part of a healthy diet. Using brown rice pastas is another way to add whole grains. Look for gluten free products that include at least some whole grains (e.g. brown rice). Gluten free breads, baking mixes and cereals are great, but aim to get about half your grains from whole grains. Adding ground nuts, flax seed or sesame seed to baking mixes can increase the fiber and nutrient content if the main flour is refined. (See table 2 for fiber recommendations)
- Dairy products:
Milk, yogurt, and cheeses are some of the highest calcium foods around, and milk and some yogurts are fortified with vitamin D. If a person cannot tolerate milk or dairy products, calcium and vitamin D can be obtained in fortified GF soy, rice or almond milks or fortified orange juice. If not eating/drinking 3 to 4 servings of one or more of these every day, a calcium and vitamin D supplement will be necessary.
There are many GF calcium and vitamin D supplements found in pharmacies, talk to your pharmacist to find the best supplement for you.
Another way to obtain vitamin D is with sun exposure to your skin. You need 5 to 30 minutes of exposure to the arms and face, without sunscreen, twice a week, when the sun is high. The darker your skin is the more sunlight exposure you need. Once you have had this amount of sun exposure, it is important to apply sunscreen to protect against skin cancer. If you live in the north (above 35 degrees latitude) the sun is too low to provide direct exposure between November and February. One can actually get vitamin D in the winter months by exposing the whole body, in a swimsuit to UVB rays via a tanning bed once per month; you need only ¾ the amount of time that it takes to actually tan. (7,8)
- Protein foods:
We get protein, many B vitamins, iron and zinc from meats, poultry, fish, and eggs. Unprocessed meats can be convenient for persons with CD, because they do not contain gluten (read the labels of any processed meat you purchase as gluten containing flours/starches may be included in fillers). We can meet our protein needs with small amounts of meat and dairy products, or with vegetable proteins such as beans, split peas, lentils, nuts, peanuts. Vegetable proteins are also a great source of fiber, but need to be mixed with grains to provide a “complete protein”; this can be difficult, but not impossible when on a gluten free diet.
Conclusion: Basically, a person with CD has the same nutrient needs as the rest of the human race, but meeting those needs while eliminating gluten can be a challenge. This web site gives you all the information you need on following a gluten free diet; this article is a reminder that we all need to eat a variety of foods to be as healthy as possible.
