Are spinach and other vegetables a true substitute for meat as an iron source?

Aug 23, 2017

Some have claimed spinach and other vegetables can be substituted for meat as an equal source of iron. However, research has shown this isn’t the case. First, the ease of absorption and utilization of iron and zinc is substantially higher after consumption of meat in comparison to vegetables. Thus, vegetarians must consume 1.8 times the amount of iron to meet the recommended intake compared to meat eaters.

Furthermore, the type of iron differs among plant and animal based found sources. Iron sources found in animal proteins contain heme iron, which has found to be more readily absorbed in the body. Whereas non-heme iron, found in plants, can be restricted during absorption due to certain compounds found in plants.

With all this in mind, it is crucial that consumers still incorporate vegetables into the diet as they are good sources of vitamins and antioxidants. However, it is important to understand the differences in plant and animal-based foods to make informed decisions when it comes to a healthy, well balanced diet.
