Answer to Question 1
She is likely on a budget, so she will choose foods that are inexpensive. She may not have much free time and will look for foods that are easy to prepare. She may not have time to read food labels and may choose foods that are filling but may not have all of the essential nutrients. She may also choose foods that are familiar to her since she doesn't have time to investigate new foods. This could lead to her choosing fast foods or processed foods, which are inexpensive and easy to prepare but often lack essential ingredients.
It is possible for a person who has limited time and finances to eat well if she/he has received nutrition education. For example, this person could select staple foods, such as brown rice, as a base for quick meals. Brown rice has more nutrients than many fast foods and is inexpensive. She could also buy whole foods like apples that could be stored at room temperature and can be taken along with her to work or with her children.
