Errata, corrigenda et commentarii: The iron content of grapes is 0.3 milligrams per 100 grams, not 5 (error due to a permutation of columns). The correct table is: --------------------------------------------------------- Carbohydrate Ca Fe Mg P K Na Zn Cu Mn --------------------------------------------------------- grapes 17 14 .3 5 10 191 2 .04 .04 .72 cranberries 13 7 .2 5 9 71 1 .13 .06 .16 blueberries 14 6 .2 5 10 89 6 .11 .06 .28 oranges 12 40 .1 10 14 181 0 .07 .04 .02 passion fruit 14 4 .4 17 25 278 6 .06 .05 ? broccoli 5.2 48 .9 25 66 325 27 .40 .04 .23 ---------------------------------------------------------- It appears that passion fruit beats grapes on most points, and broccoli beats grapes on all points except Mn. My conclusion on this is that the "Brix" is an indicator, which has its strengths and weaknesses. I don't think the usefulness of a given fruit or vegetable can be scaled by a single number. The "Brix" is certainly a simple way to judge the taste or the mineral richness of a fruit of a given variety, but comparing the Brix of a wild and a domesticated fruit is as absurd as comparing grapes and broccoli. I also forgot to talk about cranberries. I also wondered myself whether ripe cranberries would taste good. I bought 1 pound in October, and kept them in my cupboard, hoping they would one day become edible... And they are *still* there (I sometimes eat 2 or 3; perhaps I'll finish them in 6 months!). P.S. I'll try to re-read my messages more carefully before posting. Sorry for the typos and spelling mistakes (I obviously have a problem with plurals and putting the s at the proper place) [Some occasional inaccuracies of language are of course unavoidable ;-)].
