Cashews, very powerful mineral supplements
Sunday, March 24 2002 - Filed under: General
I recently tried some cashews. A year ago (6 months SCD) I couldn't
tolerate them, but now (16 months SCD) it seems like I can tolerate
I was surprised to see that I felt a lot better after I ate those. I
tried it two other days and the same happened. It gets rid of the itchy
feeling I have some of the times.
I decided to check the cashews in the nutrient investigator (
It seems like the cashew is a very powerful mineral supplement.
A massive amount of magnesium, iron, phoshporous, potassium, zinc and
As a matter of fact it's in the top #5 rating with all these minerals
in the list of *all foods* in the nutrient investigator..
Values per 100g:
Ca 45 mg (a *very* nice Mg/Ca ratio !)
Mg 260 mg
Iron 6.0 mg
Phosphorus 490 mg
Potassium 565 mg
Zinc 5.6 mg
Copper 2.2 mg
I ate 200 grams of it yesterday and it made me feel really good for the
Ca 90 mg
Mg 520 mg
Iron 12 mg
Phosphorus 980 mg
Potassium 1130 mg
Zinc 11.2 mg
Copper 4.4 mg
The question is, which mineral is causing this improvement ?
I'm already supplementing (or have supplemented) Mg and Zinc.. Calcium
is causing problems..
Because magnesium levels are so high (effectively doubling my daily Mg
dose), I will let it stay a candidate:
So that leaves:
Magnesium at 124% RDA
Iron at 120% RDA
Phosphorus at 122% RDA
Potassium 56% RDA
Copper 147% RDA
My potassium levels in the blood are already very, very high, so I
don't think potassium is causing the improvement..
So, it's either magnesium, iron, phosphorus or copper...
Or, it might be something completely else: The high carbohydrate
contents of cashews..
200 grams of cashews would yield 65 grams of carbohydrate. My total
carbohydrate would then peak at about 80-90 grams. I usually only eat
about 30 grams of carbohydrates a day..
But I think the mineral explanation is more probable..
If I check the other foods I eat that have comparable mineral levels, I
* There is no close competitor for the magnesium content of cashews.
The 2nd magnesium-food I eat often is macadamia nuts, but it contains
only 50%: 130mg vs 260mg.
* The 2nd iron-food is also macadamia, but it contains only 60% iron of
cashews: 3.7 vs 6.0.
* The 2nd-phosphorus-food is mackerel, which has 65% of the phosphorus
contents of cashews: 318 vs 490
* The 2nd-potassium-food is mackerel, which contains an almost
identical amount of potassium as cashews do
* The 2nd-copper-food is macadamia, which has only 34% copper contents
of cashews: 0.756 vs 2.220
So, the most probable candidates are:
1. Copper 147% RDA*
2. Magnesium at 124% RDA*
3. Iron at 120% RDA*
4. Phosphorus at 122% RDA*
* The percentages show how far the RDA is met when you eat 200 grams of
So, I should try to supplement these minerals one by one in to see
which one is causing the benefits..
An interesting experiment..
I suspect the magnesium, because calcium (the magnesium antagonist)
aggrevates my condition and mg-glycinate improves my condition.
Does anybody know if the magnesium in cashews is absorbed better than
the magnesium in a magnesium-glycinate supplement ? Or is it of a
higher bio-availability (elemental magnesium instead of Mg-amino) ?
Please let me know if you have any thoughts about this or comments..
