I've been concerned about cholesterol since my doctor wanted me to start taking a drug. I asked him if I could try reducing my LDL (it was 170 or so at the time) by modifying my eating/exercise habits (I was already excercising quite a bit, but my diet wasn't fantastic at the time), and I got down to 132 or so in a couple of months. Last test my LDL was 168, and my doctor didn't complain, but I know I have to watch it. I'd like to bring it down. I buy organic natural peanut butter at Costco and the label says it has 13% daily limit of saturated fat for each 2 tablespoons. I figure I can reduce the impact on my lipid problem if I replace the standing oil with olive oil. Therefore, the last 3-4 times I've opened a jar of this stuff I've poured off the standing oil and replaced it with olive oil and then stirred it in. Is that sensible/effective?
