  4. This recently published study is more interesting than the others because vitamin E was mea-
    sured in a way that is more discriminating by considering the fact that vitamin E is carried in
    the blood fat. That is, a high level of blood vitamin E may, at times, be due to high levels of
    blood fat. (Am.). Epidemiol. 150 (1999); 37-44)

  5. The effects of vitamin C and selenium in a study by Perkins (Am. J. Epidemio1. 150 (1999):
    37-44) were not statistically significant in a logistic regression model, according to the au-
    thors. I disagree with their conclusion because the inverse "dose-response" trend (high anti-
    oxidant blood levels, less memory loss) was impressive and clearly Significant. The authors
    failed to address this finding in their analysis.

  15. Alzheimer's trend was not statistically significant, perhaps due to the small number of disease

  18. There is a potential snag in this logic, however. Homocysteine levels are regulated in part by
    B vitamins, most notably folic acid and vitamin Bn, and people who are deficient in these
    vitamins may have higher homocysteine levels. People who do not consume animal-based
    foods are at risk for having low Bn levels, and thus high homocysteine levels. However, as
    described in chapter eleven, this has more to do with our separation from nature, and not a
    defiCiency of plant-based diets.
