Video Review

Linus Pauling was introduced to the subject of vitamin C by biochemist Irwin Stone in 1966. Five years later, he would pen “Vitamin C and the Common Cold,” and then boldly go on to champion vitamin C as a fighter of more serious diseases such as cancer.
According to Pauling, the vitamin’s versatility in illness prevention arises from its role in the manufacture of collagen, the protein that gives shape to connective tissues and strength to skin and blood vessels.
Pauling discusses vitamin C’s connection with lipoprotein-a, a substance whose levels in the blood have been linked to cardiovascular disease. Lipoprotein-a is also a major component of the plaques found in the blood vessels of atherosclerosis patients.
He has published studies asserting that lipoprotein-a is a surrogate for vitamin C, serving to strengthen blood vessel walls in the absence of adequate amounts of the vitamin in the diet.
Pauling is convinced that doses of vitamin C can help prevent the onset of cardiovascular disease, inhibiting the formation of disease-promoting lesions on blood vessel walls and perhaps decreasing the production of lipoprotein-a in the blood. Vitamin C’s link to healthy blood vessels, Pauling said, is further supported by studies of scurvy, the disease caused by vitamin C deficiency. Fifty percent of patients who die of scurvy, he said, do so because of ruptured blood vessels.

This video review is on Iron deficiency anaemia. Many people suffer from this, but are unaware of it. I was recently diagnosed with iron deficiency anaemia and this is the reason for me choosing this topic.

Iron-deficiency anaemia is a common type of anaemia. The term “anaemia” usually refers to a condition in which your blood has a lower than normal number of red blood cells. Anaemia also can occur if your red blood cells don’t contain enough haemoglobin. Haemoglobin is an iron-rich protein that carries oxygen from the lungs to the rest of the body.

• Haemoglobin count suppose to be within the range 14- 17 grams per decilitre in males and 12-15 grams per decilitre in females.

• Low iron levels usually are due to blood loss, poor diet, or an inability to absorb enough iron from the foods you eat.

• Iron-deficiency anaemia usually develops over time if your body doesn’t have enough iron to build healthy red blood cells. Without enough iron, your body starts using the iron it has stored. After the stored iron is gone, your body makes fewer red blood cells. The red blood cells it does make have less haemoglobin than normal. Haemoglobin is a protein that helps carry oxygen to your body.

• Infants and young children and women are the two groups at highest risk for iron-deficiency anaemia.

• The signs and symptoms of iron-deficiency anaemia depend on its severity. Mild to moderate iron-deficiency anaemia may have no signs or symptoms. Many of the signs and symptoms of iron-deficiency anaemia, such as fatigue (tiredness), apply to all types of anaemia.

• Treatment for iron-deficiency anaemia include dietary changes and supplements, medicines, and surgery.

• Eating a well-balanced diet that includes iron-rich foods may help prevent iron-deficiency anaemia. Taking iron supplements also may lower your risk for the condition if you’re not able to get enough iron from food. Large amounts of iron can be harmful.

• If you have iron-deficiency anaemia, see your doctor regularly, take iron supplements only as your doctor prescribes, and tell your doctor if you have any new symptoms or if your symptoms get worse.
