About this sweet potatoes...
I calculated the thiamin-content afterwards
to check my claim (or assumption)
of 2.5 to 3 mg of thiamin
necessary for 1kg of carb.
The "sweet potatoes" showed up to have

>  Calories      105
>  Carb (g)     24.3
> vitA (IU)    17054
> Thia (mg)     0.05

Only 2mg per kg carb... ??

Why? are they cultivated to have more carb as
natural ones?
I dont' think so, because they are not *so* sweet
and I hope close to natural occuring south-american roots.

The solution of the puzzle:

I reported the *cooked* plant.
Thiamin is instable to heat and leeching away
in cooking water ..

 Food 1-SWEETPOTATO-RAW (11507)-100:1 g

   Nutri     Food 1
-----------+--------
  Carb (g)     24.3
 vitA (IU)    20063
 Thia (mg)     0.07

Raw it goes up to 2.9mg/1000g.
The formula turned out to be right, at last.


I was just wondering...
