    Vaatasin maasika sisalduse kohta infot siit:

    http://www.thefruitpages.com/chartstrawberries.shtml

    Seal selline info A-vitamiini kohta:

    – – – – – – – – –

    Nutrient | Units | Value per 100 grams

    Vitamin A,IU | IU | 27.000

    Vitamin A,RE | mcg_RE | 3.000

    – – – – – – – – –

    Küsimused:

    Mille poolest erinevad need 2 A-vitamiini, on need mingid eri liigid sellel vitamiinil, mis erinevused neil on (üks on “väärtuslikum” v-<img decoding=” srcset=”/uploads/emoticons/smile@2x.png 2x” width=”20″ height=”20″>, ja kui kirjanduses viidatakse A-vitamiin isisaldusele maasikas, kas siis mõeldakse selle all nende kahe A-rea summat seal või, ala, et sisaldus on 27+3=30?

    Jah, arusaadav nüüd, siin ka kirjas see:

    http://www.dietobio.com/vegetarisme/en/vit_a.html

    “Units of measurement

    Vitamin and mineral amounts are usually expressed in milligrams (mg) or micrograms (mcg).

    Vitamin A values are expressed in different ways.

    The nutriment was originally measured in I.U (international unit) but in 1974 the United States began using a measurement called Retinol Equivalents (REs).

    1 RE = 1 mcg. of retinol

    1 RE = 6 mcg. of beta-carotene

    1 RE = 3.333 U.I of vitamin A

    “

    aitäh!
