Selenium the anti -cancer trace elelment

Selenium the anti -cancer trace elelment


One of the world’s rarest trace elements. Its content in food is totally dependent on its content in soil. New Zealand soil has low levels of selenium which needs to be replenished. However it is possible to get all the selenium one would need from just one Brazil nut. Selenium enhances the activity and nutritional value of other vitamins A, C and E in the body. Selenium compound is easily reduced by heat and cooking, processing and refined foods.


Selenium is a natural antioxidant, necessary for the production of prostaglandins (affecting blood pressure)

Works with vitamin E in maintaining the function of the mitochondria of cells and in promotion of body growth

Preserves tissue elasticity

Important for the male reproductive system – semen has a high selenium content

Slows the aging process – by attacking free radicals

Areas of the world with high selenium content also has lower cancer rates

Deficiency Effects

Premature aging

Immobile sperm

Cot death

Prostaglandin deficiency – results in deficiency of compounds necessary for keeping arteries free from platelet aggregation. Defective absorption can lead to neural “ceroid lipofuscinosis” a disease that accumulates pigment in nerve cells – characterised by mental retardation, diminished vision, nervous disorders, anaemia and death.


Absorption and storage

The liver and kidneys contain 4-5 times as much as the muscles and other tissue. Selenium also binds with toxic metals and removes them from the body. Normally excreted via the urine.

Medical and therapeutic Uses

Human breast milk contains up to 6 times more selenium and 2 times more vitamin C than cow’s milk

For the maintenance of the blood and circulatory system, joints, muscles, glands, heart, infertility, arthritis, stroke, hypertension, muscular dystrophy, angina pectoris, cancer, reproductive system, raises energy levels, general wellbeing, kwashiorkor (protein deficiency disease), may prevent cot death

Dosage and toxicity

Toxic symptoms include hair loss, teeth and nails loss, skin inflammation dermatitis, lethargy and paralysis.

Severe overdose produces fever, increased respiratory and capillary rate, gastrointestinal distress, myelitis and sometimes death.

Can cause inflammation of the spinal cord,


RDA 50 – 200 micrograms daily. Doses should not exceed 700-1100mg. Males require a higher dose than women due to sperm cell content.


Good Food Sources

Brewer’s yeast, organ meats, mussels, meats, fish, shellfish, grains, dairy products, eggs, Brazil Nuts. Without a doubt, Brazil nuts are one of the best sources of selenium. Shiitake/White Button Mushrooms, Lima/Pinto Beans. Chia Seeds. Brown Rice. Seeds (Sunflower, Sesame, and Flax),  Broccoli, Cabbage, Spinach.
