The European Food Safety Authority (EFSA) has proposed dietary reference values for copper, an essential micronutrient that is necessary for electron transfer processes.
The draft Scientific Opinion – the latest in EFSA’s ongoing work on dietary reference values for EU population groups – is now open for public consultation.
Webinar: eBook: Thermo Fisher Scientific Food Integrity Collection 2017
Over the course of the year Thermo Fisher Scientific have provided expert comment on a whole swathe of issues including food fraud, origin testing and labelling regulations. This collection also provides access to Thermo Fisher’s Food Authenticity webinar series for 2017, where experts delve into olive oil characterisation, gelatin speciation, honey and chromatography, and more.
Copper is an essential trace element. It is a central component of many enzymes, including those involved in neurotransmitter synthesis, in energy metabolism and in cross-linking of collagen and elastin. Copper deficiency can produce anaemia-like symptoms, neutropenia, bone abnormalities, hypopigmentation, impaired growth, increased incidence of infections, osteoporosis, hyperthyroidism, and abnormalities in glucose and cholesterol metabolism.
Grains are a good source of copper
EFSA’s Panel on Nutrition, Dietetic Products and Allergies derived Adequate Intakes (AIs) based on mean observed intakes in several EU countries. Data from balance studies in adults were used as supportive evidence. The proposed values are:
|Infants 7–11 months||0.4 mg/day*|
|Males and females 1 to < 3 years||0.7 mg/day|
|Males and females 3 to < 10 years||1.0 mg/day|
|Males 10 to < 18 years||1.3 mg/day|
|Females 10 to < 18 years||1.1 mg/day|
|Male Adults||1.6 mg/day|
|Female Adults||1.3 mg/day|
|Pregnant and lactating women||1.5 mg/day|
*mg/day = milligrams per day
The main food group contributing to the copper intake of all population groups except infants is grains. Other important contributors to copper intake are meat and meat products, starchy roots or tubers, coffee, tea and fish.
The draft Scientific Opinion is open for comment until 6 August 2015.
