Why would a pediatrician draw blood from your 9-, 10-, or 11-year-old at his or her next annual wellness visit? Because the American Academy of Pediatrics (AAP) recently endorsed updated guidelines that call for checking LDL (bad) cholesterol levels in all kids between the ages of 9 and 11.
The cholesterol-test recommendation created quite a stir. But wait, there’s more. The guidelines also call for annual blood pressure checks beginning at age 3, and periodic blood sugar measurements starting between ages 9 to 11. There’s also a strong recommendation for kids and adolescents to limit sedentary screen time to two hours or less per day, and to get at least an hour a day of moderate physical activity.
The biological basis for these guidelines is that atherosclerosis (the fatty gunk in arteries that causes heart attacks, strokes, and other serious problems) starts during youth. In many cases, Read more »

Low-fat diets, move over. When it comes to lowering cholesterol, a “portfolio” diet that includes cholesterol-lowering foods such as oatmeal, nuts, and soy products is better.
Several years ago, researchers at St. Michael’s Hospital and the University of Toronto created what they called a “dietary portfolio of cholesterol-lowering foods.” It went after cholesterol by adding to a heart-healthy diet specific foods known to lower cholesterol: margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.
In a head-to-head test against the low-fat diet traditionally recommended by the American Heart Association, the portfolio approach was the clear winner. (You can see the makeup of the test diet here.) After 24 weeks, it lowered harmful LDL cholesterol by 13%, while the low-fat diet lowered LDL by only 3%. As an added benefit, the portfolio approach also lowered triglycerides and blood pressure, and did not depress the level of beneficial HDL cholesterol. The results were published in the Journal of the American Medical Association.
What I appreciate about this study is that it Read more »

When cyclists find out that I am a heart doctor, they most frequently ask about cholesterol numbers.
“…My cholesterol is this…What do you think?”
“…My doctor wants me to take a statin…But I read that these drugs might lower my functional threshold power 2.014 watts/40km.”
All this focus on numbers saddens me. Remember, I am a forest guy, not a tree guy. What’s more, as a doctor that revels in the adrenaline rush of ablating rogue circuits with technology that would impress even a twenty-something, I find questions about biochemistry dreary–like eating quinoa.
I wish folks would ask me about how to terminate AF with a catheter, or how an (evidenced-based) ICD saved a mom’s life, or perhaps even this: “Do you do heart surgery?”
But more often than not people want to know about cholesterol.
Okay. It just so happens that this week brought some very interesting news concerning the treatment of abnormal cholesterol lab values. News that big-picture docs have to like. Read more »

The New York Times recently ran a piece that wondered if doctors were treating patients with cholesterol-lowering medication unnecessarily because a web-based calculator over estimated a person’s risk. The program was proudly sponsored by the pharmaceutical roundtable and was available at the American Heart Association.
The implication was obvious. Simple tool determines an individual’s risk for heart attack or death from heart attack. It over estimates risk. Patients treated unnecessarily. To be also clear, the program did underestimate risk as well.
Unfortunately, the article missed an important point. While the simplified calculator may not be as accurate as the more complex algorithm used by the National Cholesterol Education Program, the truth is doctors are likely to be overtreating patients not because the former program is presented by the pharmaceutical roundtable, but for another reason.

Research from the University of Michigan suggests that say one in three middle school youth who regularly eat school lunches are obese or overweight. They are also more likely to have higher cholesterol levels than kids who bring lunches from home.
The study included 1,076 middle school students who completed questionnaires about what they ate and how much physical activity they got as well as how many screen hours they logged each day.
Compared with kids who ate school lunches, kids who brought lunches from home were:
– Less likely to be overweight or obese (25% vs 38%)
– Less likely to eat two or more servings of fatty meats like fried chicken or hot dogs daily (2% vs. 6%)
– Less likely to drink two or more sugary drinks a day (7% vs. 19%)
– More likely to eat at least two servings a day of fruit (49% vs. 33%)
– More likely to eat at least two servings a day of vegetables (50% vs. 40%)
– Had lower levels of LDL (the bad cholesterol) Read more »
