Benefits of Copper

Benefits of Copper

Grinding for Pennies - Wood mortar, pestle & pennies.Like some of the other essential dietary minerals, copper is needed only in trace amounts for your body to function properly. Nevertheless, copper is vital to many of the body’s functions, so it is important to ensure that you are not copper deficient (which is actually quite rare). Since the human body cannot synthesize copper on its own, it must be absorbed by the body from the food we eat.

Copper combines with protein to produce enzymes that spur a wide range of bodily functions. It plays a key role in energy production, supports the brain and central nervous system, and helps in the creation and metabolism of neurotransmitters. It also is important in the formation of connective tissue (including that of the heart and blood vessels) and plays a part in bone formation. It is necessary for proper iron metabolism and the healthy formation of red blood cells. It is also responsible for the production of melanin, the pigment that gives color to the skin, eyes and hair. Copper acts as an antioxidant and is important for a healthy immune system.

As mentioned earlier, copper deficiency is relatively uncommon. However, some people are more prone to a deficiency than others. This includes those who have cystic fibrosis, severely restricted diets, or problems with absorption through the gut (such as individuals with celiac disease). Infants and the elderly are also more prone to copper deficiency. Infants may be more at risk they have been fed only cow’s milk formula (cow’s milk is very low in copper).

The recommended daily intake of copper is as follows:

Infants, birth to 6 months: 200 mcg/day

Infants, 7 – 12 months: 220 mcg/day

Children, 1 – 3 years: 340 mcg/day

Children, 4 – 8 years: 440 mcg/day

Children, 9 – 13 years: 700 mcg/day

Adolescents, 14 – 18 years: 890 mcg/day

Adults, 19 years and older: 900 mcg/day

Pregnant women: 1,000 mcg/day

Breastfeeding women: 1,300 mcg/day

Being deficient in copper can contribute to anemia and osteoporosis as well as a variety of other health problems. However, having too much copper in your system can actually be toxic. Signs of copper toxicity include nausea, vomiting, diarrhea and abdominal pain that can eventually lead to kidney and liver failure, coma and death. Taking high amounts of zinc can lower copper levels that have become too high.

Children should get the copper they need from their diet rather than from supplements. Adults who are considering taking a copper supplement should consult with their doctor before doing so, since it is important not to get too much copper, and it must have a proper balance with zinc. Foods rich in copper include liver, nuts (particularly cashews, almonds and Brazil nuts), seeds, legumes, clams and oysters.

Strong bones are essential for healthy living, but there’s no guarantee that any of us will have them as we grow up and grow older. While we don’t think about it very much unless something goes wrong, we need to do our part to develop and protect our bones. Proper nutrition is part of that.

Your skeleton is a living organ that needs nutrients in order to rebuild bone in areas where it is continually being broken down. Osteoporosis, a condition in which bones lose mass and density and are at greater risk for fractures, occurs in 55% of Americans over 50. Millions of fractures occur every year as a result of poor bone health.

The most common osteoporosis-related bone fractures among the elderly affect the hips, vertebrae, wrists and ribs. Vertebral fractures are the most common, and occur most often in women. You may see an elderly woman with hunched shoulders, head propped forward and unable to stand straight, because a few of her vertebrae have essentially collapsed. This condition is sometimes called “dowager’s hump”.

How do we prevent this from happening to us? In addition to regular weight-bearing exercise, diet can make a big difference. Here are some bone-friendly foods you can add to your diet to help keep your bones strong:

Seeds—Though we usually think of bones as being made of calcium, they also consist of other elements. For instance, half of the body’s magnesium is found in the bones. A great source of magnesium is seeds, particularly pumpkin seeds. Brazil nuts are also rich in magnesium.

Nuts—Walnuts are rich in alpha linolenic acid, which helps to keep bones building up instead of breaking down.

Leafy greens—Leafy greens (particularly the dark green kind), provide a host of nutrients and vitamins, including magnesium, calcium and vitamin K. Vitamin K helps to cut calcium loss in urine and is essential in building new bone matter to replace old.

Beans—Pinto beans, kidney beans, black beans and white beans all contain magnesium and even a little calcium. Beans not only help your bones, they help prevent obesity, heart disease and cancer.

Sardines—Canned sardines contain a substantial amount of calcium. A 3 oz. can typically contains 320 mg of calcium.

Swiss cheese—One ounce usually contains 270 mg of calcium.

Dried plums (Prunes)—Dried plums are a reliable source of dietary fiber, phenols and vitamin K. They’ve been shown to suppress the rate of bone resorption, or the breakdown of bone.

Besides eating well, it’s very important to remember to exercise. In fact, one of the greatest health risks faced by astronauts when they go into orbit is bone loss. Bones deteriorate more quickly in zero gravity unless exercise is included in the daily routine. The same idea applies here on earth. Stressing bones with physical activity (particularly weight-bearing exercise and exercise that involve some type of impact, such as running) seems to trigger bone-building activity and prevents the body from using bone-building nutrients for other things.
