What type of fat is most likely to cause the buildup of fatty plaques in arteries? Triglycerides Saturated fat Polyunsaturated fat Monounsaturated fat

## Step 1<br />The question is asking us to identify the type of fat that is most likely to cause the buildup of fatty plaques in arteries. This is a health-related question, specifically about the impact of different types of fats on the cardiovascular system.<br /><br />## Step 2<br />Fatty plaques, also known as atherosclerosis, are a significant cause of heart disease. These plaques are primarily composed of cholesterol, fatty substances, cellular waste products, calcium, and fibrin.<br /><br />## Step 3<br />Among the options provided, saturated fats are known to raise the level of cholesterol in the blood, which can lead to the buildup of fatty plaques in the arteries. This is because saturated fats can increase the level of low-density lipoprotein (LDL) cholesterol, which is often referred to as 'bad cholesterol'.<br /><br />## Step 4<br />LDL cholesterol can build up in the walls of the arteries, leading to the formation of plaques. These plaques can narrow the arteries or even block them, leading to serious health issues such as heart attacks and strokes.<br /><br />## Step 5<br />On the other hand, triglycerides, polyunsaturated fats, and monounsaturated fats do not have the same impact on cholesterol levels as saturated fats do. Therefore, they are less likely to cause the buildup of fatty plaques in the arteries.
