    @27min Well raw foodists were actually found to have lower plasma Beta Carotene: & ‘B_carotene.pdf’

    “However, in this study, total fat consumption
    was similar in the diet groups, which makes fat consumption
    unlikely to be the factor explaining the low plasma
    -carotene concentrations in the raw food diet group.
    Additionally, blood lipids are reported to be associated
    with plasma -carotene levels and could thus be considered
    as a covariate in the general linear model. In this
    study, we did not include them in the general linear model
    because we previously found no differences between
    total cholesterol and LDL-cholesterol in subjects consuming
    wholesome food and those on a Western diet [11] .
    The same observations were reported for raw food eaters;
    despite a negative trend for total and LDL cholesterol
    with increasing proportions of raw food, the total:HDL
    and LDL:HDL cholesterol ratios and the triglyceride levels
    were not associated with the amount of raw food consumed
    or the variant of raw food diet [12]”

    I wonder if it’s from LDL, fat intake timing w/ nutrient, or just the cooking
    “Carotenoids are transported in plasma exclusively by lipoproteins, with the distribution among lipoprotein classes determined in large part by the physical properties of the carotenoid.

    These findings confirmed previous reports using
    more nonspecific means of carotenoid analysis that the
    hydrocarbon carotenoids are transported primarily in
    LDL, whereas the more polar carotenoids are more evenly
    distributed between LDL and HDL.

    Heating of plant foods before ingestion improves the bioavailability of carotenoids pigments from many such foods, probably as a result of dissociation or weakening of protein-carote- noidcomplexes, or the dissolution or dispersion of crystalline carotenoid complexes. Such an effect has been clearly demonstrated for lycopene from tomato products (5). ”

    I have been blendtec’ing my greens with half a lemon peeled all on ice drunk with 12mm glass straw lately (with a fat source — fat soluble vitamins absorption go up 40-80%). I wonder about toxicity upper limits or tomato lectins.

    And another 2011 video similar study ‘tan vs carotenoid deposition’ was posted:

    I have heard rose hips are good for arthritis but I never read much about it:

    I heard Robbwolf describe microwaving like you did 2m46s

    What do you think of this microwaving?:
