OK, from the doc:
LDL - bad cholesterol (transports fats to the plaques in the arteries)
HDL - good cholesterol (transports fats out of the plaques)
triglycerides - really bad to have too high!
IMHO (my accumulated knowledge over 30 years) - genetics play a far bigger part of the cholesterol issue than most will admit. Of course, most females have a higher HDL, as a rule than males. :(
Back in the dark ages, in Biochemistry class it was pointed out that in most people dietary cholesterol only contributed about 20% to the measured blood level. So eating NO cholesterol at all (almost impossible) will not substantially lower a very high cholesterol. All that nutritional marketing toward low fat foods in the 80's and 90's was market-driven and "I think" contributed a good deal toward the obesity we are now seeing - substituted sugars for fats to maintain taste.
Many people truly respond to increasing their fiber intake (not a bowl of cherrios - that's hogwash). Getting their fiber intake up to 30-35 grams per day (look out co-workers) :ohmy: . Your liver makes cholesterol daily and the dietary fiber binding it in the GI tract before it can be absorbed into the blood stream.
Adkins-type diets are interesting. Quite a paradox - many people's cholesterol will go down on this. Got me !
For triglycerides, adding a high grade (even pharmaceutical grade) fish oil supplement will clearly lower this level. Inverse relationship between fish oil intake and trig. level. Really can't eat enough cold-water fish. Cheap fish oil supplements can have hvy. metal and PCP-type contaminates that come from concentrating the oil from fish having low levels of these.
Homocysteine is involved in all this heart disease stuff, so it is important to get high levels of folic acid and other B vitamins - either through foods and/or supplements.
Enough. I'm NOT a medical expert in the science of fatty acids, but due to my own genetics and lab values, have taken an interest in this over the years.
