High blood cholesterol levels are bad for the heart. Like meat, eggs, and poultry, shellfish contains cholesterol. But shellfish is not necessarily bad for the heart; it is very low in saturated fat, which affects blood cholesterol levels much more than dietary cholesterol does.

Summarize Argument
The author concludes that despite being high in cholesterol, shellfish isn’t necessarily bad for the heart. This is because shellfish is low in saturated fat, which affects blood cholesterol more than dietary cholesterol does.

Notable Assumptions
The author assumes ones of two things. First, the author may assume that there’s some level of cholesterol that isn’t unhealthy, hence why shellfish aren’t heart-unhealthy despite being high in cholesterol and thus contributing to cholesterol. Second, the author may assume that shellfish in fact offset their blood cholesterol contribution through some other, unmentioned nutritional factor.

A
Meat and eggs are high in saturated fat.
We need to strengthen the claim shellfish isn’t unhealthy for the heart. We don’t care about meat and eggs.
B
Small quantities of foods high in saturated fat are not bad for the heart.
Shellfish isn’t high in saturated fat, so we don’t care.
C
Shellfish has less cholesterol per gram than meat, eggs, and poultry do.
Shellfish can be healthier than bacon and still be bad for the heart. We’re trying to strengthen the claim that shellfish actually isn’t bad for the heart.
D
Foods low in saturated fat promote low blood cholesterol.
While shellfish has dietary cholesterol, shellfish also has low saturated fat. This promotes low blood cholesterol, thus offsetting whatever contribution shellfish otherwise makes to blood cholesterol through dietary cholesterol. On the balance, shellfish are fine.
E
A serving of meat or poultry is typically larger than a serving of shellfish.
We don’t care about servings. We’re trying to strengthen the claim shellfish isn’t bad for the heart.
