Before you use this number
- This number is not what your body gets. Plant foods contain only non-heme iron, which is absorbed far less readily than the heme iron in meat, seafood and poultry. Absorption runs about 14–18% from mixed diets that include meat, seafood and vitamin C, and 5–12% from vegetarian diets. Vitamin C and meat eaten in the same meal raise it. Phytate in grains and beans, and polyphenols in foods such as spinach, lower it. Calcium is unusual in lowering absorption of both forms. Evidence: iron-18 · iron-04 · iron-05 · iron-06 · iron-19
- High-dose zinc supplements can cause copper deficiency. This applies to supplements, not to food. People who regularly take high doses of zinc, or use large amounts of zinc-containing denture cream, can develop copper deficiency, because zinc inhibits copper absorption. Evidence: cu-04

Worth knowing
- Sodium is 603 mg per 100 g, 26% of the Daily Value. The FDA Daily Value is the reference for nutrients to limit. How much that matters depends on your whole day rather than on one food.

Source and how to read this
Data: USDA FoodData Central, SR Legacy, release 2018-04 (final), FDC ID 172684. Described in USDA as Bread, rye; we shorten these names for readability and keep the original here. Values are per 100 g of edible portion as USDA reports them; a serving may be more or less.
Portion: "1 oz" = 28.4 g is the primary household measure USDA records for this food. Per-100 g values let you compare foods; per-portion values are closer to what you actually eat.
% Daily Value: FDA Daily Values for adults and children 4+ (FDA, page updated 2024-03-05). "High" means ≥20% DV and "good source" 10–19% DV — FDA's labelling cut-offs (21 CFR 101.54), which apply per serving; we apply the same cut-offs to 100 g so foods can be compared. No DV exists for energy or total sugars, so those show no percentage.
