Celiac Disease Daily Gluten Exposure Threshold

Add up the gluten in a day's food and compare the total against the 10 to 50 mg per day range that the literature associates with mucosal safety in celiac disease. Built for dietitian review and gluten-free diet monitoring.

Celiac Gluten-Exposure Threshold EstimatorEnter servings per day for each food. The tool estimates total daily gluten (mg/day) and compares it with the commonly cited 10–50 mg/day threshold range.
Wheat bread (1 slice)≈ 2000 mg gluten / slice
White sandwich bread (1 slice)≈ 1200 mg gluten / slice
Wheat pasta, cooked (1 cup)≈ 3000 mg gluten / cup
Pizza slice (regular crust)≈ 2500 mg gluten / slice
Wheat breakfast cereal (1 cup)≈ 1500 mg gluten / cup
Wheat crackers (5 crackers)≈ 500 mg gluten / serving
Regular beer (12 oz)≈ 1500 mg gluten / bottle
Soy sauce (1 tbsp)≈ 300 mg gluten / tbsp
Uncertified oats (1 cup cooked)≈ 100 mg gluten / cup
Gluten-free bread (1 slice)≈ 5 mg gluten / slice
Gluten-free pasta, cooked (1 cup)≈ 10 mg gluten / cup
Rice, cooked (1 cup)≈ 0 mg gluten / cup

Clinical Guidance

The threshold for clinically significant gluten exposure in celiac disease is debated. A commonly cited range is 10–50 mg/day, derived from studies such as Catassi et al. and the 2007 Codex Alimentarius / EFSA discussion that set the gluten-free labelling limit at 20 ppm. Many patients tolerate small amounts without histologic change, but individual sensitivity varies widely.

The per-serving gluten values used here are representative estimates for common foods, not product-specific measurements. Actual gluten content varies by brand, recipe, and processing. This tool is an educational estimate and not individualized medical advice; a strict gluten-free diet and any threshold decisions should be guided by a gastroenterologist and a registered dietitian.
