IRON BIOAVAILABILITY FROM A VEGETARIAN DIET
Eliminating meat from the diet can be accomplished with minimal effect on the total dietary iron content. In Western countries, vegetarian diets can contain as much or more iron than mixed diets containing animal flesh (2–4). For example, Calkins et al (2) reported the iron contents of vegan, lactoovovegetarian, and nonvegetarian diets of Seventh-day Adventists, and nonvegetarian diets of a control group of non–Seventh-day Adventists, as (x ± SE) 18.0 ± 1.6, 14.2 ± 0.8, 14.4 ± 0.9, and 16.1 ± 1.1 mg Fe/d, respectively, when assessed by a 3-d food record. The total iron content of a diet, however, provides little information about its content of bioavailable iron, which is considerably influenced by the foods in the diet and can vary 10-fold from different meals of similar iron content (5). Although a vegetarian diet is likely to contain iron in amounts equivalent to amounts in a nonvegetarian diet, the iron from a vegetarian diet is likely to be substantially less available for absorption (6) because of differences in the chemical form of iron and the accompanying constituents that enhance or inhibit iron absorption
Hemochromatosis :
Hemochromatosis is an iron disorder in which the body simply loads too much iron. This action is genetic and the excess iron, if left untreated, can damage joints, organs, and eventually be fatal.
There are several types of hemochromatosis. Type 1, also called Classic Hemochromatosis (HHC), is a leading cause of iron overload disease. People with HHC (too much iron) absorb extra amounts of iron from the daily diet. The human body cannot rid itself of extra iron. Over time, these excesses build up in major organs such as the heart, liver, pancreas, joints, and pituitary. If the extra iron is not removed, these organs can become diseased. Untreated hemochromatosis can be fatal.
Iron is an essential nutrient found in many foods. Iron carries oxygen (in hemoglobin) to all parts of the body. Normally, humans absorb about 8-10% of the iron in foods that they eat. People with hemochromatosis (too much iron) can absorb four times more iron than normal.
Undiagnosed and untreated hemochromatosis (too much iron) increases the risk for diseases and conditions such as:
