Find out about copper rich foods

Copper is a mineral that is found in almost all of the foods that we eat, but which foods contain copper, and how much is needed through your diet each day? This page is a comprehensive guide to foods with copper in, with an extensive list for you to look through. We also explains why it is that copper is a mineral that is necessary to your good health, and exactly how much you as an individual should be consuming through dietary sources each day.

What is copper and why is it important to your diet?

Just as the page introduction states, copper is a mineral. It is one that is found to a degree in many of the foods that you eat everyday, and it is necessary to keep the body healthy for a variety of reasons. You need to ensure that you are regularly eating high copper foods, so that your levels are topped up and don't end up lacking and leaving you in danger of becoming deficient. This can have an adverse effect on your health and is not a good idea. However, unlike other vitamins and minerals, the total amount of copper that you need each day is rather small, and therefore not difficult to get through many common foods.

Copper helps to keep your bones strong and healthy, as well aiding in the healing of any cuts and bruises that you may suffer. Another very important reason why we need copper is that it is required for the production and storage for another vital mineral, iron. Without enough iron in your body you can become weak and anemic. With low levels of copper this outcome is all the more likely.

The copper rich foods list below will show you just how easy it is to get all of the copper you need through simple dietary sources.
