Question

Which statement describes a way in which diet contributes to cardiovascular diseases? Food high in cholesterol blocks insulin production, so the heart cannot send enough oxygen to cells.
Food high in animal fat makes the lungs unable to send oxygen to the heart, causing cardiovascular disease.
Food high in saturated fat thickens the arteries and makes it harder for the heart to send oxygen to the body's cells.

Answer 1

The right answer is the last option: "food high in saturated fat thickens the arteries and makes it harder for the heart to send oxygen to the body's cells."

The saturate fat partially passes to blood and deposit in the arterie's walls causing thickening. This thickening of arteries reduces the area trhough wich blood has to flow. The immediate consequence is that the heart has to work more (harder) to compensate the reduction of the area and keep the flow, with higher blood pressure, to send the adequate level of oxygen to the cells.
