Copper is an essential nutrient that plays many roles in our body. The document outlines dietary reference intakes for copper, lists the top 10 foods highest in copper content, provides an example of average daily copper intake, describes clinical effects of copper deficiency, and notes factors like zinc, iron, and fructose that can affect copper absorption. Osteoporosis may be linked to subclinical deficiencies in minerals like copper as levels tend to be lower in those with osteoporosis compared to those with normal bone density.

Dietary reference intakes for copper Tolerable Upper Intake Levels (UL)** Age Male Female Pregnant Lactating 1-3 yrs. 1000 µg 1000 µg 4-8 3000 µg 3000 µg 9-13 5000 µg 5000 µg 14-18 8000 µg 8000 µg 8000 µg 8000 µg 19-50 10000 µg 10000 µg 10000 µg 10000 µg 51-70 10000 µg 10000 µg 70+ 10000 µg 10000 µg **UL = The maximum level of daily nutrient intake that is likely to pose no risk of adverse effects. Unless otherwise specified, the UL represents total intake from food, water, and supplements.
Top 10 foods highest in copper 1: Liver 2: Oysters 3: Sesame Seeds and Tahini 4: Cocoa Powder and Chocolate 5: Nuts 6: Calamari and Lobster 7: Sunflower Seeds 8: Sun Dried Tomatoes 9: Roasted Pumpkin and Squash Seeds 10: Dried Herb
How much do we really eat everyday? Breakfast: Lunch: • Flakes (52g) – 1,1mg • Salad (55g) – 0mg • Juice (250g) – 0,3mg • Beef (160g) – 23mg • Milk (250g) – no data • Potatos (180g) – 0mg • Yogurt (150g) – 0,1mg • Dark chocolate (100g) – 1,8mg Dinner: • Veal (100g) – 12mg • Buckwheat (170g) – 1,9mg • Pineapple (240g) – 0,3mg Summary – the real daily consumption of copper approximately is – 40,5mg
Clinical Effects of Inadequate Intake Frank copper deficiency in humans is rare, but has been found in a number of special conditions. It has been observed: • premature infants fed milk formulas • infants recovering from malnutrition associated with chronic diarrhea and fed cow’s milk Symptoms accompanying the copper deficiency : • normocytic • hypochromic anemia • leukopenia • neutropenia • osteoporosis
Factors affecting the copper requirement Zinc Zinc intakes, well in excess of the amount normally found in the diet, can decrease copper absorption in adults
Factors affecting the copper requirement Iron High iron intakes may interfere with copper absorption in infants: • low concentrations of iron absorbed more copper • higher iron concentration less absorption
Factors affecting the copper requirement Fructose Studies in rats demonstrated that diets very high in fructose were associated with increased severity of copper deficiency in rats, but a similar effect was not observed in pigs
Osteoporosis One factor contributing to bone density loss in the elderly may be subclinical magnesium (Mg), zinc (Zn) and/or copper (Cu) deficiencies due to a reduced dietary intake and reduced absorption of these micronutrients. Mg, Zn and Cu are essential cofactors for enzymes involved in thesynthesis of various bone matrix constituents. Normal Osteopenia Osteoporosis Copper (mg/l) 1.60 ± 0.08 1.59 ± 0.09 1.54 ± 0.12
