A restaurant along my daily route makes a tasty dish of grass carp at a low price. As a result, I can afford to eat two slabs of the meat each day. It happens that grass carp is caught locally, and widely available inexpensively in my region.
The problem is I don't know its vitamin D content, if any.
Certain sites such as the following indicate no detectable level (or absence of relevant data):
...while others quote huge numbers, such as the following with 247% RDA per 100 grams of carp:
Both get their data from the USDA: The first link from USDA National Nutrient Database for Standard Reference, Release 21, and the second link from Release 24.
OTOH, I may be getting enough vitamin D - plenty. OTOH, I may require vitamin D supplementation as I hardly get any from other sources. Other than a blood test, is there a way to find out the true value?
Moreover, is the vitamin D in carp (if any) localized to the liver? Or regularly distributed throughout the fish?
