Lipids - More Than Just Fat
Lipids get a bad reputation, but they're actually essential for your body. They store energy, protect your organs, and even help insulate you like a natural winter coat under your skin.
Fats are solid at room temperature and usually come from animals - think butter, lard, and fatty meat. Oils stay liquid and mostly come from plants like olives, avocados, and sunflowers. Both contain carbon, hydrogen, and oxygen, but lipids have way less oxygen than carbohydrates.
The key difference is saturation - saturated fats (mostly from animals) can clog your arteries, while unsaturated fats (mostly from plants) are much healthier for your heart.
Health Check: Your body needs some fat to function, but too much saturated fat increases your risk of heart disease. Balance is everything!
