（参照老师ppt第五页 加点图加点东西）
One Effect
Iron deficiency is very common among women.
Two Causes
(1)Women’s health leads to iron deficiency.
a. Too many women ignore the amount of iron they take in;
b. Women’s monthly bleeding is a major source of iron loss;
c. Many women increase their risk of iron loss by rejecting red meat;
d. Women are liable to experience a deficiency as a result of restricting their diet in weight control.
(2)Exercise can result in iron loss through a variety of mechanisms
a. The average woman takes in only 2/3 of the recommended daily allowance for iron, which would easily cause iron deficiency if they take some exercises. (Para. 5)
b. Some iron is lost in sweat, and intense endurance exercises may cause iron deficiency through bleeding of the digestive system and bleeding of the blood vessels in the feet. (Para. 6)
——
Part III (Para. 7-12)

Problems of iron deficiency: (Paras. 7 - 8)
a. Fatigue and poor performance may begin to appear when not enough iron is present in their
blood to form the molecules of blood protein that transport oxygen to the working muscles.
b. When their iron reserves go to zero, people often feel weak, tired, and out of breath — and their exercise performance is severely compromised; and they are in trouble.
c. It is advisable for people in these groups to have a yearly blood test to check blood iron reserves.
Solution to the problem: (Paras. 10 - 11)
a. It is advisable for people in these groups to have a yearly blood test to check blood iron reserves.
b. If iron levels are low, talk with a physician to see if the deficiency should be corrected by modifying your diet or by taking supplements.(Para. 10)
c. Select breads and cereals with the words ‘iron-added’ on the label(Para.
11)
d. Eat the foods with plentiful Vitamin C to enhance the amount of iron absorbed. (Para. 11)
e. Cook in iron pans, as food can derive iron from the pan during the cooking process. ( Para. 11)

Any relationship between iron and exercise?
——
Negative effects:
