And whether it is enough to give them their RDA of copper :-)
Give or take, it far, far exceeds our minimal requirements
Copper Recommended Dietary Allowance
(milligrams/day)
Adult 0.9
Pregnant woman 1.0
Nursing mother 1.3
And we get more than enough in a good diet, without adding any!
Sources of copper
The table below indicates the approximate copper content in a range
of foods:
Food Copper
(mg/100g
edible portion)
Potato 0.22 Baked, without salt, flesh only
Potato 0.17 Boiled, no skin, no salt
Mushrooms 0.24 Canned, drained
Green Peas 0.14 Frozen, cooked, drained, no salt
Banana 0.10 Raw
Raisins 0.36 Golden, seedless
Peanuts 0.67 Dry roasted, no salt
Peanuts 1.14 Raw
Brazil Nuts 1.77 Dried, unblanched
Chick Peas 0.17 Canned
Chick Peas 0.85 Raw
Sunflower Seeds 1.75 Kernels, dried
Chocolate (Dark) 0.80 Dark chocolate bar
So. What happens if we get too much copper?
HIGH COPPER
Copper levels are more often too high rather than too low. High copper
can be toxic.
Physical Symptoms of High Copper: Headaches….Hypoglycemia….Increased
heart rate….Nausea
Copper deposits in the brain and liver….Damage to the kidneys….Inhibit
urine production….Causes anemia….Causes hair loss in women….High
copper interferes with zinc, which is needed to manufacture digestive
enzymes. Many high copper people dislike protein and are drawn to
high-carbohydrate diets because they have difficulty digesting protein
foods….Excessive copper in children is associated with hyperactive
behavior, learning disorders such as dyslexia, ADD and infections such
as ear.
Psychological Symptoms of High Copper: Autism type
symptoms….Depression….Hallucinations
Hyperactivity….Insomnia….Paranoia….Personality
changes….Psychosis….Schizophrenic type symptoms
Overstimulation….Disperception of the senses, time, body, self and
others. Produces hypomanic states
Detachment from reality.
As we can see, I would suggest many here already exhibit many of these
symptoms!
