Explain the difference between LDL and HDL cholesterol, including their effects on cardiovascular health.

LDL cholesterol is associated with cardiovascular diseases because it can accumulate on blood vessel walls, leading to inflammation and narrowing of the arteries. HDL cholesterol is considered 'good' because it helps remove excess LDL from the blood and brings it back to the liver for excretion, reducing inflammation.

Describe how saturated and unsaturated fats affect LDL cholesterol levels in the body.

Saturated fats can drive the liver to create more VLDL and LDL packages, increasing LDL cholesterol levels. Unsaturated fats have anti-inflammatory properties that help counteract LDL buildup.

Besides diet, what are two lifestyle factors mentioned in the video that can influence cholesterol levels, and how do they affect them?

Exercise can lower LDL and increase HDL, while smoking increases LDL buildup.
