Appreciate the analysis by Dean Pomerleau here. Couple questions. Regarding fiber intake comparison between EPIC-Oxford vs. Adventist groups, Dean says EPIC got about half the fiber. But I'm told the EPIC study reports fibre as Non-Starch Polysaccharides (NSP) while the Adventist study reports AOAC fibre. Based on https://pubmed.ncbi.nlm.nih.gov/23543118/ Table 2, which reported both measures of fibre, NSP fibre needs to be multiplied by 1.54 to get AOAC fibre. If this is done then the differences become rather small (27g NSP becomes 42 g AOAC) compared to 46 g in the table Dean post from Adventist study. So if that's correct and fiber is not as low in EPIC group as thought, that would leave Dean's points about social support, B-12 and Vit C as differences and possible clues for lack of EPIC longevity, compared to Adventist. Any further musings there? Thanks.
