According to the University of Maryland Medical Center, tea, such as green tea, can reduce the risk of atherosclerosis, high cholesterol, cancer, inflammatory bowel disease and diabetes. However, although tea boasts several health benefits, drinking too much can reduce iron levels, which can contribute to or worsen iron deficiency.
Identification
Iron works to produce the protein hemoglobin, which makes up red blood cells in your body. In addition, iron carries oxygen through the bloodstream and throughout the entire body. Although iron can be obtained through both vegetable and meat sources, people with digestive issues or women with heavy menstrual cycles may not get enough and will need to take iron supplements to prevent iron deficiency. Too little iron in the body can cause iron deficiency, which, according to the Centers for Disease Control and Prevention, is the most common cause of anemia in the United States.
Causes
One of the main causes of iron deficiency is a decreased iron intake or decreased absorption. According to the Centers for Disease Control and Prevention, substances such as polyphenols, phytates or calcium can decrease iron absorption. In addition, substances found in tea called tannins block iron absorption as the iron surges through the digestive system.
Considerations
If you are at risk of developing iron deficiency, consult with your physician about taking iron supplements or increasing iron sources in your diet. One way of increasing iron intake is to combine both heme and non-heme iron sources. Also, do not drink tea with an iron-rich meal.
Concerns
Untreated iron deficiency can lead to iron deficiency anemia. Symptoms of iron deficiency anemia are lack of energy, shortness of breath, headache, irritability, dizziness or weight loss, according to MedlinePlus. Iron deficiency anemia is treated by using iron supplements or increasing iron in your diet. Additionally, your doctor may advise you to avoid substances that decrease iron absorption.
