Mission: reduce cholesterol

Wednesday, June 17, 2009

Last week, I got a call from the doctor's office telling me that I have high cholesterol. It was a real shock. I knew that my total cholesterol was up last time I had a blood test, but the doctor said that my HDL ("good" cholesterol) was high, so the balance between the two numbers was good. This time, my HDL was 76, but my total was 250-something (I don't have the paperwork with me right now). You'd think this would have shown up before I started to pay attention to my diet and exercise, and I feel a bit betrayed by my body that it's showing up now. But, then, my body's been a Benedict Arnold before. I should expect its little tricks.

When I get news like this, I feel the need to gather information. What can I do to help lower my cholesterol? Some things, we all know, but I'm going to summarize what I find here. And since I'm such a good little librarian, I'll put links and citations at the end of this blog so you can find the resources yourself.

Eat foods high in soluble fiber: Oatmeal is the one that comes to mind first. Yep, no surprise, if you've paid any attention to health news in the last decade. I don't know if there's some Oatmeal Marketing Association that put this news out, or what. But other foods high in soluble fiber include: kidney beans, apples, pears, psyllium, barley, okra, eggplant, and prunes.

Nuts: Walnuts are the top dog, here, but I have a weird (allergic?) reaction to them. So a handful of almonds, pine nuts, pecans, peanuts, or pistachios might be in order.

Omega-3 Fatty Acids: I thought these just raised your good cholesterol, but evidently they actually lower your numbers. Salmon, mackerel, herring, sardines, albacore tuna, ground flaxseed, canola oil.

Olive oil: Lowers LDL, but leaves HDL intact.

Soy protein foods: This one's controversial, evidently, because early studies showed it does make a difference, but later ones showed no significant difference. Soy protein is found in tofu, soy nuts, soymilk, soy burgers, edamame, and miso.

Foods fortified with plant sterols and stanols: I have wondered about those little yogurt shots and I bought some this week. I'd rather get benefits from whole foods, not a supplement like this, but I thought that a little extra dairy a day would also be good for my calcium levels.

Diet with less than 10% saturated fats: I think I'm there, but I'm going to cut back further on my lowfat cheeses, which I think is about the only place I get sat fat on a regular basis.


Regular exercise: Doing that!

Red Yeast Rice: This supplement was examined in quite a few studies and it seems to lower cholesterol. However, as with all supplements, the efficacy depends on the exact composition of the individual supplement, and it can vary widely.

    Great blog. Thanks for sharing info.

    I have been working on reducing my cholesterol without medication and have started to see results.

    I have added exercise, oatmeal, 1 TBL psylliam husk daily, ground flaxseed tea (1 TBL in warm water, seep for 6 minutes) almonds, avocado to my diet.

    I have reduced cheese intake, and eat red meat only occasionally.

    I have been willing to make these changes because I don't believe in medication unless it's absolutely necessary. For me, taking a pill to reduce cholesterol instead of making healthy changes just doesn't make sense.

    Good info here. Your ability to do excellent research shows through. With your permission, I will print this out and share it with BIL who believes that a little pill gives him license to continue to live on tortilla chips and 16 oz steaks. This is a nice, concise report that even he might read.

    Hey, we have something in common. I also react to walnuts. I call it an allergy because I'm assuming it is. I get a sudden itchy rash all over my neck. I never cared that I couldn't eat walnuts until I learned they're an outstanding source of Omega 3s. Having this issue can be a problem when restaurants fail to mention they used walnut oil in that salad dressing.
