bAcceptable MacronutrientDistribution Range (AMDR) isthe range of intake for a particular energy source thatisassociated with reduced riskof chronic disease while providing intakesof essentialnutrients If an individualhasconsumed in excessof the AMDR, there isa potentialof increasing the riskof chronic diseasesand insufficient intakesof essentialnutrients.

aAsretinolactivity equivalents(RAEs). 1 RAE = 1 µg retinol, 12 µg β-carotene, 24 µg βcarotene, or 24 µg β-cryptoxanthin. The RAE for dietary provitamin Acarotenoidsis twofold greater than retinolequivalents(RE), whereasthe RAE for preformed vitamin Ais the same asRE

bAscholecalciferol. 1 µg cholecalciferol= 40 IUvitamin D.

cUnder the assumption of minimalsunlight.

dAsα-tocopherol α-Tocopherolincludes RRR-α-tocopherol, the only formof α-tocopherol thatoccursnaturally in foods, and the 2R-stereoisomeric formsof α-tocopherol(RRR, RSR, RRS, and RSS-α-tocopherol) thatoccur in fortified foodsand supplements. Itdoes notinclude the 2S-stereoisomeric formsof α-tocopherol(SRR, SSR, SRS, and SSS-αtocopherol), also found in fortified foodsand supplements.

eAsniacin equivalents(NE). 1 mg of niacin = 60 mg of tryptophan; 0–6 months= preformed niacin (notNE)

fAsdietary folate equivalents(DFE) 1 DFE = 1 µg food folate = 0 6 µg of folic acid from fortified food or asa supplementconsumed with food = 0.5 µg of a supplementtaken on an empty stomach.

gAlthough AIshave been setfor choline, there are fewdata to assesswhether a dietary supply of choline isneeded atallstagesof the life cycle, and itmay be thatthe choline requirementcan be metby endogenoussynthesisatsome of these stages.

hBecause 10% to 30% of older people may malabsorb food-bound B12, itisadvisable for those older than 50 yearsto meettheir RDAmainly by consuming foodsfortified with B12 or a supplementcontaining B12

iIn viewof evidence linking folate intake with neuraltube defectsin the fetus, itis recommended thatallwomen capable of becoming pregnantconsume 400 µg from supplementsor fortified foodsin addition to intake of food folate froma varied diet

jItisassumed thatwomen willcontinue consuming 400 µg fromsupplementsor fortified food untiltheir pregnancy isconfirmed and they enter prenatalcare, which ordinarily occursafter the end of the periconceptionalperiod the criticaltime for formation of the neuraltube
