I’m often asked about the different types of fats & how they interact with blood lipids. Here’s a very good summary of “The Facts on Fats.”
Discovery Health :: The Facts on Fats
In a nutshell:
- trans-fat–really bad (lowers “good” cholesterol, raises “bad” cholesterol)
- saturated fat–bad when overdone (raises total cholesterol)
- mono & polyunsaturated–good in moderation (depending on the source, can lower “bad” cholesterol & raise “good” cholesterol)
A typical American diet overdoes omega-6 fatty acids & is lacking in omega-3 fatty acids, so the last bullet point is actually a good blog subject for another day.
