Copper-rich foods
Copper is an essential trace element that is present in all body tissues. It is an important mineral that our body needs in small amounts to maintain good health. It is required for various body functions, such as energy production, boosting brain health, supporting the immune system, and maintaining healthy bones and nerves. Copper also works with iron to help the body form red blood cells and connective tissue.
Since our body cannot produce copper on its own, we must obtain it from our diet. Shellfish, such as oysters, are excellent sources of copper. Oysters are low in calories and provide 7.6 mg of copper per 100 grams, which can fulfill your daily copper requirement. However, it is important to note that oysters are also high in zinc, which can interfere with copper absorption. Other types of seafood, such as lobster, are also good sources of copper.
Organ meats, particularly liver, are extremely rich in copper. Just one slice of calf liver provides 10.3 mg of copper, which is 11 times the Reference Daily Intake (RDI). However, it is important to note that liver also contains high amounts of vitamin A, which can be harmful to unborn babies, so pregnant women should avoid consuming excessive liver.
In addition to shellfish and organ meats, there are many other copper-rich foods. These include nuts and seeds, especially almonds, cashews, and sesame seeds. Dark leafy greens, such as spinach, are also good sources of copper. Whole grains, beans, potatoes, dried fruits like prunes, cocoa, black pepper, and yeast are also copper-rich foods.
It is recommended that adults get 900 mcg of copper per day. However, pregnant or breastfeeding women should aim for slightly more, with a recommended intake of 1 mg or 1.3 mg per day, respectively. While it is important to ensure adequate copper intake, excessive intake can also be harmful. Therefore, it is always advisable to maintain a balanced diet and consult a healthcare professional or a registered dietitian for personalized dietary advice.

Copper and pregnancy
Copper is an essential trace element that has several health benefits for pregnant women and their unborn children. It is a mineral that supports the healthy growth and development of the foetus and meets the nutritional needs of the expecting mother.
Benefits of Copper During Pregnancy
During pregnancy, copper is necessary for the proper development of the foetus, including the baby's brain, circulatory system, and bones. Copper also supports the development of the unborn child's cardiovascular system, skeletal system, and nervous system. Copper is a component of myelin, a substance that acts as an insulator of nerve cells and allows the impulses to be transmitted in the nerve. It also aids in iron absorption, helping to form red blood cells and prevent anaemia in the mother.
Copper is also important for the mother's health during pregnancy. It helps to boost the immune system, which is crucial as the mother's immune system changes during pregnancy to protect her and the baby from infections. Copper also plays a role in connective tissue formation, including collagen and elastin synthesis, which is important for the development of blood vessels, bones, and connective tissue. Additionally, copper helps to restore low serum copper levels, preventing symptoms associated with deficiency, and acts as an antioxidant, protecting the mother and foetus from oxidative stress.
Recommended Copper Intake During Pregnancy
The recommended daily intake of copper during pregnancy is 2 to 3 milligrams per day. Pregnant women can obtain this recommended amount through a properly balanced diet or by taking copper supplements. However, it is important to note that excessive copper intake can be harmful, and it may be preferable to avoid supplements altogether to maintain a healthy balance of copper and other minerals such as iron and zinc.
