Because albumin is a protein, foods that contain protein are different types of meat products, milk, cheese, eggs, nuts, beans and certain grains. One of the liver's functions is the production of albumin, which is necessary for healthy body tissues. Although low levels of blood albumin can be caused by a diet that is low in protein, a low albumin count also can indicate certain medical conditions like kidney or liver disease, states the National Institute of Health.
Some other causes of low albumin counts are inflammation due to different types of infections like UTIs. People that are undergoing peritoneal dialysis may experience low albumin levels, reports the DPC education Center.
The normal level of albumin in blood should be between 3.4 and 5.4 g/dL, relates the National Institute of Health. Through a blood test, the albumin level can be determined.
