When I get my annual physical, I always have blood work done, too. I have often wondered at the various breakdowns of cholesterol. Herewith, an explanation from the Harvard Medical School.
Q. My recent cholesterol test result included “non-HDL cholesterol.” What is the significance of this number?
A. Your non-HDL cholesterol result refers to your total cholesterol value minus your HDL cholesterol. When you get your blood drawn for a cholesterol test (also known as a lipid profile or lipid panel), the report usually includes four numbers: low-density lipoprotein (LDL) cholesterol; high-density lipoprotein (HDL) cholesterol; triglycerides; and total cholesterol.
Although you might assume total cholesterol is simply the sum of your LDL and HDL, it also includes very-low-density lipoprotein (VLDL). These particles carry triglycerides to tissues and eventually become LDL. Like LDL, it also causes cholesterol to build up on the inside of arteries, creating artery-clogging plaque. Both are considered undesirable, so the higher your LDL and VLDL values, the higher your risk of heart disease. Continue reading
Last Thursday, I posted Tips on fighting the flu. I thought it was a good time for these tips as we are entering flu season. Also, I had an appointment to get my own flu shot on the following day. Please check out that post as there is a lot of good information in it for you relevant to protecting yourself from the flu bugs eating away at your system.

Some people swear by flu shots (me) and some swear at them. The decision is yours, of course. I would offer anecdotally that I started getting them around 16 years ago when I was teaching journalism at Northwestern University. One of my students interviewed a senior citizen who said that she had been getting flu shots for 10 years and in that time she had not only not caught the flu, but she didn’t even catch a cold. That was good enough for me. I have been getting them ever since with similar results. Continue reading
