Your roommate Sally has just found out her mother has high cholesterol. Knowing that health problems often run in families, Sally has decided to eliminate cholesterol from her diet. Her goal is to have no cholesterol in her body. She has asked you for advice on achieving this goal. Is her goal realistic? Explain. What information should you give her to help her establish a more realistic goal?
Assuming she could banish cholesterol from her body, what would be the endocrine consequences?
What will be an ideal response?
Her goal is not realistic. If Sally avoids eating animal products, she can easily eliminate cholesterol from her diet. She cannot, however, eliminate cholesterol from her blood because it is produced by her own liver. Furthermore, such a goal is incompatible with life, as cholesterol is a structural component of cell membranes. Cholesterol is also the precursor to the steroid hormones, which are essential for normal health.
