Will Coffee Mess Up A Cholesterol Test

Myth #: Your Cholesterol Should Be As Low As Possible

Does Coffee Raise Cholesterol?

As with almost everything in health and wellness, there’s a balance that needs to be maintained. There are very few extremes that are going to serve you well.

People with too-low levels of cholesterol may have increased risk of death from other non-heart-related issues, like certain types of cancers, as well as suicide.

We commonly hear that a high level of LDL in blood increases risk of plaque formation inside arteries – raising risk of a heart attack. Conversely, the lower the LDL level, the lower the risk of heart attack.

This is a simplistic and incomplete picture.

Its not just the total amount of LDL cholesterol that should be of concern, but also the type and size of the LDL particle. Research indicates that those whose LDL particles are predominantly small and dense, have a significantly greater risk of cardiovascular disease, whereas the large and fluffy type of LDL may actually be protective.

Its a similar story with HDL cholesterol. Commonly perceived as the good type, HDL cholesterol acts like a scavenger, and removes harmful LDL cholesterol, by transporting it to the liver for processing. But were finding out, that the size of the HDL particle is of significance as well. This research indicates that women who had larger HDL particles had a higher risk of atherosclerosis, versus those who had smaller HDL particles.

Size really matters when it comes to cholesterol.

Tips To Help You Fast Properly Before A Blood Cholesterol Test

By | Submitted On May 01, 2010

Doctors almost always instruct to fast before going in for a blood cholesterol test. You need to fast in the correct manner if you have scheduled a blood cholesterol test. It’s always a good idea to check with your doctor as well as the lab where you’ll have the blood work done about any specific instructions for the pre-test fasting.

Follow these tips and you will not mess up your test:

1. Keep track of what you’ve been eating in the few weeks before the blood cholesterol test if you know much in advance when you’d be doing the blood test. If your blood test is part of a life insurance medical exam, stay away from red meat, fried foods and other high fat and high cholesterol foods.

2. The best time to schedule a blood cholesterol test is early in the morning, especially if you need to fast for 12 hours. This way you can have your last meal of the day by 7 PM and then go first thing in the morning for your blood test.

3. Make sure you check with your doctor or with the people at the lab about how long you need to fast. The time period could anything from 6-8 hours to even 12 hours depending on the case.

Does Sugar Turn Into Cholesterol

Excess sugar is known to contribute to obesity, diabetes, and other conditions linked to heart disease, and now new research links it to unhealthy cholesterol and triglyceride levels. People in the study who ate the most added sugar had the lowest HDL, or good cholesterol, and the highest blood triglyceride levels.

More Evidence That Fasting Not Needed Before Cholesterol Tests

This page was fact checked by our expert Medical Review Board for accuracy and objectivity. Read more about our editorial policy and review process.

A new analysis recently published in JAMA Internal Medicine adds to the evidence that people may not have to fast before blood tests to check their cholesterol and other lipid levels. Researchers from Brigham and Womens Hospital, Harvard Medical School, and Imperial College in London reviewed data from a study called the Anglo-Scandinavian Cardiac Outcomes TrialLipid Lowering Arm for their analysis.

Blood tests to check lipid levels, including total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels, are done routinely to help determine a persons risk of heart disease and to decide if and what treatment is necessary. Adults are usually instructed to fast for 9 to 12 hours before these tests, which are typically done together as a lipid panel.

The analysis found little difference between the fasting and non-fasting lipid results from the same individuals, according to the authors. The only difference was moderately higher triglyceride levels in non-fasting samples, which was expected. The researchers also found that fasting and non-fasting lipid levels had similar associations with coronary events. Non-fasting lipid levels reflected risk for heart disease similar to fasting levels.

What To Expect During The Test

Can you drink black coffee when fasting for glucose test?

A cholesterol test is a simple blood test during which a technician will generally seat the person in a chair with a special armrest. The technician will then tie a rubber strip around the persons arm to try to find a suitable vein from which to draw blood.

After finding a vein, the technician will clean the area with alcohol, insert a needle attached to a tube into the persons vein, and allow the tube to fill.

When the tube is full of blood, the technician will remove the needle and hold gauze on the site of the puncture. The technician may ask the person to apply pressure for a few minutes to stop the bleeding, and they might apply a small bandage over the gauze.

At this point, the test is complete, and the person is usually free to go about their normal daily activities.

The results will tell a doctor if the levels of cholesterol in a persons blood are healthy.

The test measures several types of cholesterol in a persons blood in mg/dl. It is possible to break down the results by type of cholesterol.

HDL cholesterol

HDL results measure the amount of good cholesterol in a persons blood. Higher readings tend to be better than lower readings:

60 mg/dl or higher

Caffeine And Blood Sugar

If you don’t have diabetes, the Mayo Clinic says drinking coffee shouldn’t noticeably affect blood sugar levels. Most healthy young adults can safely take in up to 400 milligrams of caffeine a day, which is more than the typical caffeine found in two 8-ounce cups of coffee.

If you do have diabetes, however, caffeine may affect your blood sugar levels. Caffeine may raise blood sugar for some diabetics, while it may lower blood sugar for others. Caffeine affects everyone differently, the Mayo Clinic says.

There aren’t a lot of clinical studies measuring the effects of coffee on a blood glucose test. A small study of coffee drinkers in the September 2012 edition of the journal Metabolism measured the effects of caffeine from espresso coffee. It found only marginal differences in glucose measures between coffee drinkers and noncoffee drinkers.

What Supplements Have Biotin

On top of getting biotin from your foods, this substance can also be taken from various vitamins or supplements available in drug stores.

For example, most multivitamin pills, B-complex vitamins, and coenzyme R have high amounts of biotin in them. Similarly, supplements with vitamin H and prenatal vitamins might also contain biotin.

If youre taking some supplements for hair growth and skin improvement, chances are that youre also getting some biotin from those. Look on the labels of the supplements you take and look for biotin, vitamin B7, vitamin H, or coenzyme R to see if your pills contain biotin.

If you have been instructed to stop biotin supplementation a few days before your blood test but forgot to do so, make sure that you inform your doctor about it. Your health practitioner needs to know this is the case your results show inaccurate or confusing results.

Why High Cholesterol Can Be Dangerous

Cholesterol is manufactured by your body’s liver and carried in your bloodstream to cells throughout your body by proteins. While it’s important to your health, the body makes all the cholesterol you need. Your cholesterol level can be too high if you are eating foods with lots of cholesterol, mainly foods with high levels of saturated fats such as red meat, dairy and eggs. When your cholesterol level is too high, it can build up in the walls of your blood vessels and may eventually restrict blood flow causing a heart attack or stroke.

Coffee’s Other Effects On Cholesterol

Censorship Pt. 2, Anxieties On The Future And Loving The “Mess” In WoW – Coffee With Soul

When we think about cholesterol, we generally think that “high” means “bad.” And, while this is certainly true with LDL cholesterol, increased levels of HDL cholesterol are generally considered a good thing.

Among its benefits, HDL cholesterol absorbs excess cholesterol in the blood and carries it back to the liver where it is flushed out of the body. Increases in HDL generally correspond to decreases in the risk of heart disease and stroke.

A 2020 study in the Journal of Nutrition reported that while high consumption of unfiltered espresso did, in fact, increase TC and LDL levels in both men and women, it also increased “good” HDL and decreased “bad” triglyceride levels. Decreased triglycerides are linked to a lower risk of heart disease.

The same study also noted that regular consumption of tea and instant coffee had no detrimental effect on a person’s blood lipid profile.

Avoiding Coffee Before A Blood Test

What is the latest thinking on avoiding coffee before a blood test?

You have a problem. You must fast for 12 hours before your blood test, but you have a real dependence on coffee or caffeine. You need that cup of caffeinated energy before you even walk out the door. Otherwise, grogginess, a headache and a general feeling of malaise may set in.

May we suggest that you get up earlier than your usual coffee time and arrive at the laboratory as early as possible? The only problem is, many medical testing labs open at 8 a.m., well past the time most people are up and getting ready to take on the day. And the busiest time of the day for most labs is 8 a.m. to 10 a.m.

‘can I Drink Coffee While Fasting’

I heard the same question almost every time I gave pre-op instructions to a patient: Once I got to the part about nothing to eat or drink after , nearly every one of them would look at me in anguish and ask, Does that mean no coffee??

I feel you.

As a connoisseur of caffeine, myself, I understand that fasting can be difficult enough without giving up coffee to do it. And the good news is: sometimes you dont have to!

The answer to this question depends on the type of fasting youre doing. Can you drink coffee while doing

Pre-surgical fasting? No, you absolutely may not drink coffee after the cut-off time youre given. Thats because the medications used in general anesthesia make it easy for stomach contents to regurgitate into the esophagus, where they can be inhaled. Not good. So, you should never eat or drink anything for several hours prior to a surgery with general anesthesia.

Intermittent fasting? Yes, you can drink black coffee if youre doing intermittent fasting . IF is based on a concept called time-restricted feeding in which you take in calories only during a small window of time each day. But black coffee does not contain calories, so drinking it wont break your fast. Now, if you add cream or sugar, then youve blown your fast because those things contain calories.
