I would say #2, because it is very important to eat a well balanced diet while also working out and staying physically active to stay healthy! However, the question asks, "Which of the following is a guideline for practicing good nutrition." That being said I would say #4 "Consume foods with a variety of nutrients and adequate portions. Hope this helps!
The answer should be B because people with problems that have to do with drugs and alcohol don’t usually like to get help but their family cares about them and wants them to get help for their own well being.
