Answer:
Analyze the patient's diet to quantify cholesterol intake
Step-by-step explanation:
All red meat has a high rate of saturated fatty acids, which can greatly increase the rate of bad cholesterol in the body, which in turn can cause heart problems. When this type of meat is consumed in excess, saturated fatty acids can accumulate in the body, causing several problems.
If the doctor wishes to determine whether the man's heart disease is totally related to his environment, he must observe the man's diet, since it is proven that he comes from a family that eats a lot of red meat.
