Tittel: BV proteiner Skrevet av: Thinner på 25. desember 2002, 18:09 A quick side note on what I mean by "protein quality." The quality of a protein is determined by how well your body can use it, a factor termed "biological value," BV for short. This rating is calculated by taking the total nitrogen retained from eating a protein and dividing that by the total nitrogen absorbed by eating that protein. Basically, it refers to how well and how fast your body actually gets and uses the protein. So a whey like whey isolate (BV 159) is the most readily absorbed, while a milk protein like casein (BV 77) is absorbed less readily and is said to be pf less quality. Now, sometimes it's good to eat lower BV rated proteins because you want to absorb it slowly, like before you go to bed. But generally, you want protein with a higher BV rating, because you're body is getting more of the protein you're ingesting, and more quality products use higher quality proteins. Here's a list of some common proteins with their BV:
Whey Protein Isolate 159 Whey Protein Concentrate 104 Whole Egg 100 Egg White 88 Chicken/Turkey 79 Casein 77 Soy 74 ut i fra dette er vel whey protein isolate best eller? Tittel: Re:BV proteiner Skrevet av: Nocturne på 26. desember 2002, 13:02 Man lærer så lenge man lever... ::)

NOPE ! Protein Isolate er ikke nødvendig vis best , det spørs hvilken egenskap du vil ha ut av pulveret og i hvordan du vil bruke det Tittel: Re:BV proteiner Skrevet av: Joachim B på 26. desember 2002, 18:43 Lite mätmetoder på proteinkvalitet:
BV (Biological Value) är ett mått på vilket den andel av kväve från proteinkällan som tas upp genom kosten behålls och utnyttjas. 100 är bra. PER (Protein Efficiency Ratio) är ett mått där viktökning mäts under en tidsperiod och korrigeras till intaget mängd protein. Över 2,8 anses bra. PDCAAS (Protein Digestibility Corrected Amino Acid Score): vid beräkning av proteinpoäng uttrycks innehållet av varje nödvändig (essentiell) aminosyra i procent av innehållet av samma i en referensmall, i detta fall för barn (växande människor). Enligt denna evalueringsmetod får en ideal proteinkälla, som tillgodoser människans behov av alla essentiella aminosyror, ett PDCAAS på 1,0. Detta behov varierar gång på gång men är alltid baserad/anpassad till växande barn och människor i svältländer. Reflektioner: Vassleprotein har ett PER på 3.0. Den senaste evalueringsmetoden för protein, som fastställs av WHO, är PDCAAS - där man tar hänsyn till proteinets biotillgänglighet (PD) och aminosyreprofil (AAS). Vassleprotein, rent generellt, har ett PD på 100 % och ASS på 1.16. Detta ger ett PDCAAS på 1.16. Kasein har ett PD på 99 % och ett AAS på 1.19, vilket ger ett PDCAAS på 1.17-1.18. Vasslets fördelar: mättar inte, utmärkt för att skapa en positiv (anabol) kvävebalans snabbt speciellt efter träningen och på morgonen. Kaseinets fördelar: mättar, perfekt att ta innan läggdags, mildrar en negativ (katabol) kvävebalans.

Cross flow micro filtrert whey er bedre. Det har fordelene til både whey consentrate og isolate.. Mht aminosyre sammensetning og hastighet på opptak. ;) |
