Table 4.
Data used to derive nutrient intake values (NIVs) for lactating women from breast-milk losses of folate by country 1.
| Country | Milk Folate Concentration | Daily Milk Production | Losses Per Day | Adjustment for Bioavailability | Addition in Requirement 2 | Added to ANR or INL98 |
|---|---|---|---|---|---|---|
| Austria, Germany and Switzerland 3 | 80 µg/L | 750 mL/day | 60 µg/day | 50% | 120 µg DFE/day | ANR |
| European Community | 50–100 µg/L | 750 mL/day | 37–75 µg/day | 50% | 150 µg/day | INL98 |
| The Netherlands | 60 µg/L | 800 mL/day | 48 µg/day | 50% | 100 µg DFE/day | INL98 |
| Denmark, Iceland and Sweden | 60–85 µg/L | 750 mL/day | nc | 50% | 100 µg/day | INL98 |
| United Kingdom | − | − | 40 µg/day | 66% | 60 µg/day | INL98 |
| United States and Canada | 85 µg/day | 780 mL/day | 66 µg/day | 50% | 130 µg DFE/day | ANR |
ANR: average nutrient requirement; DFE: dietary folate equivalents; INL: individual nutrient level; nc: not calculated in report; 1 NIVs are calculated as an additional requirement that is added to the NIV for NPNL women; 2 values may be rounded; 3 proposed values to be approved August 2013 [86].
