Climate change could be affecting the nutritional value of our food.
Multiple studies have shown a decline in the mineral and protein content of crops globally.
Scientists analyzed harvest samples from a total of 41 major crops; including wheat, rice and field peas, among others. The crops were raised in an environment that mimicked CO2 levels projected for mid to the end of the century. Under these conditions, iron concentrations in wheat dropped an average of 5%, zinc levels also fell 9%. In most other crops nutrient decline was also the trend.
Scientists say these changes will likely hit women and children the hardest. Lack of zinc raises a pregnant woman’s risks of premature delivery and can affect growth in children. It’s also vital when it comes to supporting a healthy immune system.
