Elimination diets can help determine food sensitivities and allergies. They involve temporary restriction of foods believed to contribute to symptoms until symptoms resolve. Common foods restricted during the diets include wheat, dairy, soy, nuts, eggs and fish. During elimination diets, seeking nutrients from other foods is important. According to the University of Maryland Medical Center, elimination diets are not definitive but can help reduce the list of suspected problem foods. Elimination diets should be supervised by a doctor.
Complex Carbohydrates
Complex carbohydrates provide valuable amounts of nutrients, dietary fiber and glucose--the body's primary energy source. When wheat is restricted during an elimination diet, wheat-free grains, such as brown rice, wild rice, oats and popcorn are valuable complex carbohydrate sources. Starchy vegetables, such as winter squash, potatoes and sweet potatoes, provide similar benefits as well as cartenoids--a potent form of antioxidants. The Dietary Guidelines for America suggests at least three one-ounce servings of whole grains daily for most adults.
Protein and Calcium-Rich Foods
Protein supplies the body with amino acids, which are the building blocks of lean tissue, and enhances tissue repair, mental concentration and blood-sugar balance. Elimination diets may restrict protein-rich foods, such as dairy products, soy, fish and shellfish. Valuable protein sources that can be consumed during elimination diets include lean meat, poultry and legumes. Since dairy products are the primary source of dietary calcium in most Americans' diets, according to the American Dietetic Association, consuming nondairy calcium sources is also important during elimination diets. Almonds (if nuts are permitted), black-strap molasses, broccoli, enriched rice milk, figs and leafy green vegetables supply valuable amounts of calcium and other nutrients.
Fruits and Vegetables
Fruits and vegetables supply an assortment of vitamins, minerals and antioxidants. Fortunately, all fruits and vegetables are permitted in most elimination diets. The Dietary Guidelines for Americans suggests approximately two cups of fruit and 2 1/2 cups of vegetables daily for adults who consume 2,000 calories per day. A variety of fruits and vegetables, including dark green, orange, starchy and other types of vegetables daily can help ensure broad, diverse nutritional benefits during and following elimination diets.
Healthy Fats
Dietary fats support nutrient absorption, healthy cell development, food enjoyment and satiation. Since saturated and trans fats increase the risk for obesity, type 2 diabetes and weight gain, the American Heart Association recommends unsaturated fat sources, such as olive oil, canola oil, ground flaxseed and avocado. Nuts, though a valuable sources of healthy fat and other nutrients, may be restricted during elimination diets.
