Does what you eat the night before affect cholesterol test?
Does what you eat before the test matter?

- animal fats, including butter, lard, and margarine.
- fatty meats.

Improper fasting, medications, human error, and a variety of other factors can cause your test to produce false negative or false positive results. Testing both your HDL and LDL levels typically produces more accurate results than checking your LDL alone.
Too little sleep also leads to high levels of LDL cholesterol, according to a study published by the Journal of Cardiovascular Nursing . Individuals who slept less than six hours each night greatly increased their risk of developing cardiovascular disease.
Scientists now agree that eating has only slight, clinically insignificant effects on three parts of the lipid profile: total cholesterol, and both HDL- and LDL-cholesterol. Food does raise triglyceride levels for several hours, usually to a modest degree. After a high fat meal these increases can be striking.
Even eating high-cholesterol foods like eggs or shrimp on the day of a cholesterol test, he said, would have little impact on results. "Cholesterol levels change extremely slowly in response to food intake. That is why it is so difficult to get your cholesterol down by changing food habits," he said.
The thinking was that testing in a fasting state would allow a more accurate and reliable reading due to food's effect on lipid levels. But that thinking has changed. A 2016 study by researchers at Harvard Medical School revealed that cholesterol levels did not vary significantly between fasting and nonfasting states.
Research has suggested that fasting may not be necessary before all cholesterol and triglyceride tests. However, people who are having these tests should refrain from drinking alcohol for 24 hours before the test.
Yes, it is possible for dehydration to skew the results of a cholesterol test. This is attributed to the fact that dehydration can cause blood volume to decrease, leading to a drop in blood pressure and blood flow. When this occurs, it increases the risk of cholesterol accumulation in the arteries.
What is the most important number in a cholesterol check?
Your HDL (“good” cholesterol) is the one number you want to be high (ideally above 60). Your LDL (“bad” cholesterol) should be below 100. Your total should be below 200. Talk with your provider about what your results mean for you and how to manage your cholesterol.
