I want to know the answer to the following question:
What did the studies show there was a lack of understanding of by the population?
All the background I'm provided with is that "Among these problems are the lack of information about food choices, a lack of understanding of nutritional information and its application to individual circumstances, limited or difficult access to healthful foods, and a range of cultural influences and socioeconomic constraints such as low levels of education and high levels of poverty that decrease opportunities for healthful eating and living.". Is that enough to answer the question?
Answer: yes
