  • Iron is an important component of hemoglobin and muscle cells

  • Iron is also necessary for the formation of many enzymes in the body

  • The body recycles iron: When red blood cells die, the iron in them is returned to the bone marrow to be used again in new red blood cells

  • A small amount of iron is lost each day, mainly in cells shed from the lining of the intestine

  • This amount is usually replaced by the 1 to 2 milligrams of iron absorbed from food each day

  • Food contains two types of iron: heme iron (found in animal products) and nonheme iron (found in most foods and in iron supplements)

  • Nonheme iron accounts for more than 85% of iron in the average diet

  • However, less than 20% of nonheme iron that is consumed is absorbed into the body

  • Nonheme iron is absorbed better when it is consumed with animal protein and with vitamin C

  • Since you are taking iron, I wonder if you are anemic? If so, you may need time before your lack of energy improves

  • Do you eat more than one serving of a food per day that provides 100% of your iron requirement? Studies of heart disease point to many risk factors, not just meat consumption

  • Plants are loaded with and people on plant based diets, like the Chinese, have iron intakes that exceed Americans - furthermore, the iron is well absorbed and utilized; so that iron deficiency anemia is rare in pure vegetarians

  • Dairy-consuming vegetarians commonly develop iron deficiency because of multiple effects of on iron metabolism

  • The form of in plant materials is nonheme (2%) which is not as absorbable as heme iron (23%) found in meat

  • There are other factors such as cast iron cookware and the presence of foods high in that increase iron absorption

  • Smith Iron is necessary for the formation of chlorophyll, which is responsible for the green color in plants and is the source of plant food and energy

  • When the amount of iron available to plants is inadequate for normal growth, leaves become pale green, yellow or white and eventually brown, particularly between the veins

  • Severely affected plants fail to grow flower or fruit and may even die from lack of iron

  • Iron chlorosis occurs most often in pin oak, white oak, white pine, magnolia, holly, sweet gum, dogwood, azalea and rhododendron

  • Iron chlorosis may occur as a result of one or a combination of causes

  • The condition is often due to high pH, which makes it possible for other elements to interfere with the absorption of iron, rather than to a lack of iron in the soil

  • Chlorosis may be caused by an actual deficiency of iron or by application of excessive amounts of lime or phosphate to certain soils

  • This will reveal if elements are deficient or in excess and, therefore, interfering with iron uptake

    Introduction to anaemia, causes and different types.

  • Diet low in iron

  • What are the different types of anaemia? The main types of anaemia are caused by shortages of iron, vitamin B12 and folic acid, all of which are needed (among other things) to produce red blood cells, so if one or more of these are missing or running low then anaemia will develop

  • Iron deficiency anaemia The most common type of anaemia is iron deficiency anaemia, which basically means the body is running low on iron

  • The body needs iron to successfully produce haemoglobin the substance that carries oxygen throughout the body

  • The main reason why people may have a shortage of iron is because the body is losing blood faster than the body can remake it

  • In women the most common reason for iron deficiency is menstrual bleeding (periods)

  • Another possible reason for a shortage of iron is diet, which is low in iron

  • Good sources of iron include fruit, dark green vegetables, wholemeal bread, fortified breakfast cereals, beans and meat

  • Is there anything I can do to avoid becoming anaemic? To avoid getting anaemia you should stick to a and ensure you eat food that contains good sources of iron, folic acid and vitamin B12

  • Iron Vitamin A deficiency may exacerbate deficiency

  • Vitamin A supplementation has been shown to have beneficial effects on iron deficiency anemia and improve iron nutritional status among children and pregnant women

  • The combination of vitamin A and iron seems to reduce anemia more effectively than either iron or vitamin A alone

  • Iron Supplemental (38-65 mg/day of elemental iron) but not dietary levels of iron may decrease zinc absorption

  • This interaction is of concern in the management of iron supplementation during pregnancy and lactation and has led some experts to recommend zinc supplementation for pregnant and lactating women taking more than 60 mg/day of elemental iron

  • The therapeutic use of metal chelating (binding) agents like penicillamine (used to treat copper overload in Wilson's disease) and diethylenetriamine pentaacetate or DTPA (used to treat iron overload) has resulted in severe zinc deficiency
