The most common single nutrient deficiency today is iron deficiency. Conventionally, the risk of iron deficiency is thought to be lowest right after child birth. However recent research has shown that the prevalence of iron deficiency and anemia is growing, especially among low income women. The standard American diet is insufficient to meet the iron needs of pregnant women. If left unsupplemented, most women are at risk of developing iron deficiency during pregnancy.
These days it's difficult to sort through all the research about health and diet without becoming overwhelmed and down right confused! So many people seem to know what diet is best and they often contradict other expert dietitians. This is the reason that I love studying traditional foods. Scientific research is always changing and evolving the more we learn about food and the human body but the intuitive knowledge of our ancestors is a solid foundation that we can build off of and will remain reliable.
