You should also skip the fettucini alfredo before a regular blood workup. “If you wouldn’t normally have a high-fat meal, then don’t do it, so your physician can get an accurate picture of your health,” says Deepa Iyengar, MD, associate professor of family and community medicine at McGovern Medical School at UTHealth and an attending physician at Memorial Hermann-Texas Medical Center. Unusually large meals could skew test results. In fact, you may need to avoid eating in general. “If your blood work will include a measurement of cholesterol or other fats, it is best to avoid any calories for eight to ten hours before the test is drawn,” says Dr. Dewar. “Your blood sugar and certain fats in the blood called triglycerides can be increased for a bit after you eat.” And you may not have a choice: you’ll probably be told to fast before a regular blood workup, says Dr. Iyengar Make sure you know the right questions you should be asking your doctor.
