Ive been doing the cholesterol battle for a few years.
We seem to have a family history of it running high. When Im not on the meds, Im anywhere between 240 and 280. Diet and exercise helped the HDL out (Im usually 53-59) but just had a tough time shoving the LDL down.
Your Trigs are way high, you want those under 150.
On the good side, you've caught this stuff early so you can do battle with it now.
As for blowing the test from eating poorly a few days before....everything Ive read says that wont usually effect the test. Based on your other 2 followups, its still high.
Usually they wait 4-6 weeks to retest.
Fish Oil helps a bit, as Toad mentioned. Ground Flaxseed (at your local GNC) added to some lowfat yogurt can help too.
The biggest thing is your diet, cut the fats. If you are still high despite those changes, welcome to the world of statins
Im on pravastatin, a generic form of Pravachol. Its brought me down to 209 (HDL 59, Trigs 99)
Im still working to get results like Toad
Some of the other ideas posted above are good. Go lean on the meats.
Cholesterol is one phase of the battle, hows your blood sugar and blood pressure?
