第三个误区：燕麦能减肥，所以随便吃。燕麦确实扛饿，但热量是实打实的：干燕麦每 100 g 约 379 kcal。扛饿能帮你控制总热量，但不等于可以不限量。
所以燕麦是好食物，前提是选配料表只有燕麦的产品，避开加糖的版本。

Breast milk 3–10 mcg/L; cow's-milk formula 30–100 mcg/L; soy-based formula 200–300 mcg/L (higher than milk-based, not a 50–75× ratio). Fact sheet (updated March 29, 2021; Wayback snapshot 15 September 2026): humans absorb only about 1% to 5% of dietary manganese; more than 90% of absorbed manganese is excreted via bile into the faeces; multivitamin/mineral supplements that contain manganese typically provide 1.0 to 4.5 mg, and manganese-only or few-nutrient supplements mostly contain 5 to 20 mg; people with chronic liver disease eliminate manganese poorly (fact sheet). ods.od.nih.gov/factsheets/Manganese-HealthProfessional
National Institutes of Health, Office of Dietary Supplements. (2024). Iron — Fact Sheet for Health Professionals. Fact sheet (updated September 4, 2025; Wayback snapshot 21 September 2026): RDAs 8 mg/day for men and for women 51+, 18 mg women 19-50, 27 mg pregnancy; UL 45 mg/day from age 14; bioavailability about 14%-18% from mixed diets with meat, seafood and vitamin C and 5%-12% from vegetarian diets; serum ferritin below 30 mcg/L suggests iron deficiency and below 10 mcg/L IDA, but inflammation can raise ferritin; supplemental iron of 45 mg/day or more may cause nausea and constipation; people with hereditary hemochromatosis are at risk of iron overload (fact sheet). Heme vs nonheme: heme iron (lean meat and seafood are the richest sources) has higher bioavailability than nonheme iron, and other dietary components affect it less; calcium might reduce the bioavailability of both forms; heme iron is about 10%-15% of total iron intake in western populations. The sheet gives no separate heme and nonheme absorption percentages (fact sheet, Wayback 2026 snapshot). ods.od.nih.gov/factsheets/Iron-HealthProfessional
