Answer:
c. Increase intake of refined foods.
Step-by-step explanation:
The American Dietetic Association does not recommend that vegetarians increase their intake of refined foods. In fact, refined foods are not recommended for any type of person. When foods are "refined," these are stripped of much of their nutritional content. Because of this, refined foods generally have a low level of fiber, vitamins and minerals. A high intake of refined foods is linked to a great variety of health problems.
