Histidine rich foods
Histidine (symbol His) is an α-amino acid that is used in the biosynthesis of proteins. It is an essential amino acid, since it cannot be synthesized in the body, and therefore it must be supplied with the food.
It is a precursor to histamine, a vital inflammatory agent in immune responses.
The imidazole sidechain of histidine is a common coordinating ligand in metalloproteins and is a part of catalytic sites in certain enzymes.
Histidine is also important in hemoglobin in the red blood cells. More on histidine here.
The Recommended Dietary Allowance (RDA) is 14 mg/kg body weight/day for adults 19 years and older.
Below is a list of foods having the highest content of histidine in grams (g) per 100 grams of the food. The list also includes the number of kilocalories (kcal) and the histidine content in grams (g) per kcal, and the list is sorted with respect to the latter with the highest values at the top.
As you can see there are many foods having a rather high histidine content per kcal. So if you are lacking in histidine, you could easily correct the deficiency by eating some of these foods. Rather small amounts should be sufficient in most cases.
The list is made using ECstep’s Personal Nutrition Data Program and includes more than 100 of the histidine richest foods. Commercial brand products are not included in this list.
