THE IRON-DEFICIENCY PROBLEM And the Causes in Our Body system

THE IRON-DEFICIENCY PROBLEM

 A deficiency of iron in the diets of young girls and women is a cause of growing concern. Iron deficiency can produce anemia, and the need for iron is universal. Generally, there is no problem in men, who require only 10 milligrams (1/3,000 of an ounce) of iron a day to maintain adequate body stores. 

But menstruating and pregnant women require 18 milligrams a day, and dietary analyses indicate that many adolescent girls and menstruating women have an iron intake of only 10 milligrams a day. Some studies reveal iron-deficiency anemia in as many as 60 percent of pregnant women. The problem centers around the fact, that overall iron content of foods on the market runs around 10 milligrams for every 2,000 calories.

Thus, unless she is paying particular attention to iron, a woman consuming 2,000 calories a day will not be getting adequate amounts of the mineral. The fact is that 50 to 60 percent of iron in the diet comes from cereals and meats, with nearly equal contributions from each, but the proportion of cereals and meats consumed by women varies widely. 

Whenever weight is a problem, too, the tendency is to reduce consumption of cereal products. Most meats provide 2 to 3 milligrams of iron per 3-ounce serving. Dry beans and nuts provide about 5 milligrams per cup. Most leafy green vegetables contain from 1 to 4 milligrams per cup.

Egg yolk, whole grain and enriched bread, potatoes, oysters, dried fruits, and peas are other good sources. There are on the market a number of prepared breakfast foods fortified with high levels of iron; some provide 8 to 10 milligrams per one-ounce serving. The use of iron-fortified food items when necessary to achieve adequate iron intake can be an important aid to health. For some women with high iron requirements-during pregnancy or because of abnormal menstrual losses-physicians may need to prescribe supplemental iron preparations.

How Vitamins act and their influence in our body care?

VITAMINS

 About $1.5 billion is spent yearly for vitamins, much of it by healthy people convinced by high-powered advertising that they need extra vitamins. While essential, vitamins are required only in minute amounts, and a fully adequate supply is provided by a balanced, varied diet. To be sure, some people, relatively few, may need vitamin supplementation because they do not absorb certain vitamins properly when they are on vigorous reducing diets. In such cases, medical advice is required. 

Vitamins in excess cannot restore the vigor of youth or perform other assorted health miracles. If diet is poor, vitamin-deficiency diseases may result: scurvy, with its gum bleeding, muscle aching, general weakness caused by deficiency of vitamin C; rickets with its bone deformities from deficiency of vitamin D; pellagra with its mental deterioration from deficiency of one of the B vitamins (niacin).

Correction of a deficiency when it exists may produce near-miraculous changes. But unless there is an actual deficiency, increasing vitamin intake with supplements-adding more to what is already adequate---can be useless, needlessly expensive, and in the case of some vitamins such as A and D can be harmful, since these two vitamins can accumulate in the body to poisonous levels. Some interesting, though not definitive, reports on the possible value of large doses of vitamin C taken early during a common cold have appeared recently.

The following table lists excellent sources of principal vitamins: Vitamin E Vegetable greens: beets, kale, chard, mustard, spinach, turnips Yellow vegetables: carrots, yellow squash, sweet potatoes Beef liver Cod-liver oil, halibut-liver oil  Vitamin B (several vitamins, including niacin and thiamine, make up the B family) Liver, pork, beef, salmon Whole-wheat bread, enriched bread, oatmeal and other cereals Peanuts, peanut butter Vitamin C Citrus fruits: oranges, lemons, grapefruits, limes Tomato juice (fresh or canned) Strawberries, raspberries, gooseberries, currants Vitamin D Halibut-liver oil and other refined fish-oil preparations Vitamin D milk Exposure of the skin to sunlight 

WHEN TO EAT? TIMING MATTERS

WHEN TO EAT

Meal patterns generally are dictated by custom, work schedule, and personal preference. Most people eat a light breakfast, moderate lunch, and hearty evening meal. If you have a preference, however, for more but smaller meals, there is certainly nothing wrong with eating that way. 

In fact, we believe that, where feasible, more but lighter meals are desirable since they are easier to digest and put fewer loads on the body. The fact is that there is a limit to what the body's chemistry can take on at any one time. 

One can add to a fire a reasonable amount of wood The Food You Eat I 53 or coal and have a vigorous flame. But if too much fuel is added, the fire huffs and puffs, smokes and smolder’s inefficiently.

So, too, with the body when it is burdened with dealing with a big evening meal,

 For example, Quite possibly, too, if a large amount of fat or cholesterol is consumed at one sitting, the body may not be able to metabolize it completely, and it may overflow into vital areas such as the arteries. 

When obesity is a problem, the practice of eating five or six small meals daily may be helpful. There are fewer tendencies to overeat when smaller portions are taken more often-and fewer tendencies to indulge in snacks. When you know you will be eating again in two hours or so, the temptation to snack is not so great. 

How much and What foods we have to take?

Cereals and breads

4 servings of enriched or whole grain cereals and breads

One serving equals 1 slice of bread; 1 small biscuit or muffin; 1 cup of potatoes, pasta, or rice; 3/4 to 1 cup of flaked or puffed cereal; or 1/2 cup of cooked cereal.

Fruits and vegetables

4 servings, including one of citrus fruit or tomatoes and one of dark green or leafy vegetable

One serving equals 1/2 cup of canned or cooked fruit; 1 fresh peach, pear, etc.; 1 cup of fresh berries or cherries; 1/2 cup of cooked vegetables; or 1 cup uncooked leafy vegetables.

Meat and protein rich foods- 2 servings of meat, fish, poultry, eggs, or cheese

 Occasionally nuts, dried beans, peas may be substituted for the meats. 

One serving equals 3 oz. of lean, cooked meat; or 3 eggs; or 3 slices (ounces) of cheese. Foods selected each day from each of the four groups provide balance; and by varying the choices within each group, you can expect to achieve a desirable averaging of intake of trace elements as well as other essential nutrients. 

For the same reason, it is a good idea, we suggest, for you to sample unusual foods whenever you can-internal organs such as liver, kidney, heart, sweetbreads, sea-foods, Italian and Chinese vegetables, and other national dishes.
