Answers

Answer 1

Too much saturated fat can contribute to heart disease and stroke. How does it have
this effect on the body?

Answers

Answer:

Your body needs healthy fats for energy and other functions. But too much saturated fat can cause cholesterol to build up in your arteries (blood vessels).

Explanation: bad LDL cholesterol in your blood

Too much saturated fat can contribute to heart disease and stroke, and this happens because of the deposition of fat and cholesterol on the arteries of the body. This causes high blood pressure and a cardiac attack.

What are the various types of fat?

Animals consume macronutrients such as fats, proteins, and carbohydrates, but not all fats are healthy and easily digestible. Fats are mostly found in animal products, oil seeds, and dairy products, but not in vegetables or fruits. Saturated fatty acids, unsaturated fatty acids, and polyunsaturated fatty acids are all types of fats, with unsaturated fatty acids being better for your health than saturated fatty acids.

Saturated fatty acids and cholesterol are frequently blamed for heart attacks and high blood pressure. The reason for this is that they continue to deposit in the blood vessels, which makes the heart pump irregularly.

Hence, too much saturated fat can contribute to heart disease and stroke, and this happens because of the deposition of fat and cholesterol on the blood vessels.
