Researchers from Duke-NUS Medical School (Duke-NUS) in Singapore found that the higher intake of red meat and poultry is associated with significantly increased risk of developing diabetes, which is partially attributed to their higher content of heme iron
in these meats.
, found in animal foods such as meat, poultry, fish, clams and eggs, is two to three times as usable as the non-heme iron
found in plant foods such as beans, leafy green vegetables and nuts.
was due to its heme iron
, which can help create carcinogenic compounds in the GI tract.
While various seeds and dried fruits do supply iron, it is in the form of an iron salt, which is about one-tenth as available as heme iron
from animal sources.
His Master's degree research for instance involved development of nutritionally superior sausages through harnessing the bovine blood heme iron

Thus, the use of whey in the production of venison sausage seems to be justified by the fact that venison has a large amount of heme iron
which makes it susceptible to oxidative changes.
Because there is evidence suggesting a role for heme iron
in colorectal carcinogenesis (heme iron
can increase production of carcinogenic A-nitroso compounds) (Bastide et al.
Vegetarians are at an additional disadvantage because heme iron
(derived from meat) is more readily absorbed than non-heme iron
and heme iron
also facilitates the absorption of non-heme iron
in a mixed diet.
intake and acute myocardial infarction: a prospective study of men.
Although various transporters have been identified , the mechanisms of intestinal uptake and release of heme iron
are less clearly understood, but the majority of heme is degraded in the enterocytes and iron is released by ferroportin, as ferroportin-deficient mice are not viable .
Lechon, barbecue, and hamonado - All made from pork, which is a very good source of protein and heme iron
but also high in saturated fat and cholesterol.
