How the percentages are calculated
Percentages compare 100 g of this food with EFSA adult daily references. Ranges reflect different adult reference groups, not measurement uncertainty. A dash means there is no compatible comparison; it does not mean zero. These are not personal targets.
- Calcium: 950 mg/day (population reference intake). Healthy European adults aged 25 years and over.
- Iron: 11–16 mg/day (population reference intake). Healthy European adults; men and postmenopausal women / premenopausal women.
- Magnesium: 300–350 mg/day (adequate intake). Healthy European adults; women / men.
- Phosphorus: 550 mg/day (adequate intake). Healthy European adults.
- Potassium: 3500 mg/day (adequate intake). Healthy European adults.
- Sodium: 2 g/day (safe and adequate intake). Healthy European adults, including pregnant and lactating women.
- Zinc: 6.2–16.3 mg/day (population reference intake). Healthy European adults; range across sex and phytate-intake categories.
- Copper: 1.3–1.6 mg/day (adequate intake). Healthy European adults; women / men.
- Manganese: 3 mg/day (adequate intake). Healthy European adults.
- Molybdenum: 65 µg/day (adequate intake). Healthy European adults.
- Selenium: 70 µg/day (adequate intake). Healthy European adults.
- Vitamin C: 95–110 mg/day (population reference intake). Healthy European adults; women / men.
- Vitamin B1 (thiamin): 0.1 mg/MJ (population reference intake). Healthy European adults. USDA food values are mass per 100 g, so an energy-based PRI cannot be divided into them without an energy intake denominator.
- Vitamin B3 (niacin): 1.6 mg NE/MJ (population reference intake). Healthy European adults. USDA reports niacin mass per 100 g; an energy-based niacin-equivalent PRI is not the same definition.
- Vitamin B6: 1.6–1.7 mg/day (population reference intake). Healthy European adults; women / men.
- Vitamin K: 70 µg/day (adequate intake). Healthy European adults; phylloquinone.
