Do I Need To Cut Down On Dietary Cholesterol

LDL: When Is It Low Enough? | Morning Report

Most people dont need to cut down on the cholesterol thats found in foods- so you can still enjoy eggs and shellfish.

Its much more important to cut down on foods which contain saturated fats. Thats because saturated fats affect how the liver handles cholesterol. So, eating saturated fats can raise your blood cholesterol. Try to replace saturated fats with unsaturated fats which are better for your heart.

For some people; those with familial hypercholesterolaemia , those who have high cholesterol, and those who are at high risk of or have cardiovascular disease; the recommendation is to limit cholesterol in food to no more than 300mg a day. In the case of FH,;ideally less than 200 mg a day.

Even though dietary cholesterol only has a small effect on blood cholesterol, people with high cholesterol and FH already have high levels of blood cholesterol, so it seems sensible not to eat too much cholesterol in food.

How Does Diet Affect Cholesterol Levels

Your cholesterol level has a lot to do with what foods you choose to put on your plate.;

In the United States, Cardiovascular Disease is one of the leading causes of poor health, sometimes accompanied by death.;

This happens to be directly associated with poor eating habits.;

For instance, consuming too much fat can increase LDL cholesterol. Subsequently, elevating the risk of heart disease.;

However, choosing a healthy diet reverses this process, giving you a clean bill on health.;

And if these are not enough, there are other foods to sink your teeth into in order to balance your cholesterol level.

Here are some foods to increase HDL and decrease LDL levels.

What Is A Healthy Blood Cholesterol Level

For people who have plaque in their arteries or who have other factors that put them at risk for cardiovascular disease, doctors recommend an ideal LDL level well below 70 mg/dl. For those without risk factors who have an LDL level at or above 190 mg/dl, the recommendation is to get this level down to below 100 mg/dl. People age 40 to 75 who are living with diabetes and whose LDL is at 70 or above may need medication.

Very high levels may cause symptoms such as fatty bumps on your skin, called;xanthomas, or grayish-white rings around the corneas in your eye, called;corneal arcus. These mostly develop in people who have familial hypercholesterolemia.

Undiagnosed or untreated high blood cholesterol can lead to serious problems, such as heart attack and stroke.

How To Lower Your Elevated Ldl Cholesterol

Cholesterol is naturally produced by your body and is essential to its function throughout your everyday life. However, excessively high levels of cholesterolin particular, LDL cholesterol are bad and can lead to serious health problems such as clogged arteries, heart disease, and stroke.

What is LDL Cholesterol?

LDL stands for Low-Density Lipoproteins. This type of cholesterol is produced by the liver and is instrumental in the creation of cell walls, hormones, and digestive juices. However, when your LDL level is high, it can start to form a plaque-like substance on the walls of your cardiovascular system, blocking the natural flow of blood and leaving you at severe risk for heart attack and stroke. Put simply, LDL is the bad kind of cholesterol. But fear not there are several ways in which you can lower your LDL cholesterol and encourage the development of High-Density Lipoproteins , which actually function to limit the level of LDL cholesterol in your system.

Consider; Screening for Familial Hypercholesterolemia ?

Familial hypercholesterolemia is a genetic disorder that causes dangerously high levels of LDL, or bad cholesterol from birth. If you have a family history of heart disease and very high cholesterol, you may have FH. FH can be diagnosed with a simple blood test, or lipid panel. Learn more here.

You Need A Little Not A Lot

Cholesterol is in every cell in your body. You need cholesterol to help your brain, skin, and other organs do their jobs. But eating too much fat and cholesterol is a bad idea.

Cholesterol floats around in your blood and can get into the walls of the blood vessels. This can cause the blood vessels to get stiffer, narrower, or clogged. If the clogging gets worse over many years, it can cause a heart attack or stroke in adults.

Cholesterol can start to build up in childhood. Doctors can find out what your cholesterol level is by taking a little of your blood and testing it.

Cholesterol Movement Between Membranes

Cholesterol can move between membranes by vesicular transport , by collision between two membrane surfaces, by cholesterol binding proteins, and through an intervening aqueous phase, though the latter is a minor mechanism because of the very low solubility of cholesterol in water. In the laboratory, cholesterol can also be moved in and out of membranes by incubation of the membranes with lipid vesicles, in which case some of the cholesterol is transferred to the vesicle membranes. Membranes can also be depleted of cholesterol by incubation with a synthetic polymer, methyl-β-cyclodextrin.

Studies on the kinetics of the movement of cholesterol from one membrane to another have revealed the mechanism of that movement. Several studies with small phosphatidylcholine vesicles indicated cholesterol can move between vesicles by transfer through the aqueous phase.14 Perhaps most dramatic was the observation that cholesterol could transfer between two vesicle populations separated by a membrane impermeable to the vesicles.15 The latter transfer was very slow. Transfer can be enhanced significantly by collision of donor and acceptor membranes.

It is interesting that cholesterol transfers through the aqueous phase even though the hydrophobic effect determines that the solubility of cholesterol in water is vanishingly small. Not surprisingly then agents that increase the critical micelle concentration apparently enhanced the exchange rates.16

High Ldl Cholesterol Diagnosis

Types of Cholesterol

A blood test can check your LDL, HDL, and total cholesterol levels. It also measures triglycerides, a type of fat that stores extra energy from your diet. High triglyceride levels can make you more likely to have heart problems.

Experts recommend testing every 4 to 6 years. Youâll probably need it more often if you have heart disease or diabetes, or if high cholesterol runs in your family.

Lower numbers are better when it comes to LDL cholesterol test results. The general guidelines for adults in the United States are:

  • Less than 100 milligrams per deciliter : Optimal
  • 100-129 mg/dL: Near or above optimal
  • 130-159 mg/dL: Borderline high
  • 160-189 mg/dL: High
  • 190 mg/dL and above: Very high

If you have a condition like heart disease or diabetes, your doctor might recommend an LDL target of 70 mg/dL or below.

How Much Does The Test Cost

You may find it helpful to talk with your doctor about the costs of cholesterol testing. The cost of cholesterol testing may depend on several factors:

  • What type of cholesterol test is being taken
  • Whether LDL is being calculated or measured
  • Insurance coverage
  • Where the test is being performed

Blood testing is typically covered by insurance when prescribed by a doctor, but you may be responsible for out-of-pocket costs on copays, deductibles, or technician fees.

How Does Fh Raise Cholesterol

Cholesterol is made by your liver and carried in your blood all around your body. Its taken out of your blood and into your cells to be used or stored, and any excess cholesterol can be carried back to your liver and broken down.

FH can cause problems with these natural processes. LDL cholesterol; cant be taken out of your blood quickly or easily, so your cholesterol can build up.

Your genes play a role in your cholesterol levels because they affect the way your cells take cholesterol out of your blood. FH happens when you inherit a faulty gene from one of your parents; the proper name for a fault or alteration in a gene is a mutation.

Where Does Cholesterol Come From

Cholesterol in your body comes from two main sources: your liver and your diet.

Your liver, other organs, and other cells in your body produce about 80 percent of the cholesterol in your blood.

The other 20 percent of cholesterol in your body is affected by the foods you eat. Foods high in trans and saturated fats can contribute to unhealthy cholesterol levels.

As you take in more of these fats, your liver compensates by reducing its own production of cholesterol and removing excess cholesterol. However, not everyone makes and removes cholesterol with the same efficiency.

Some people have genes that tell their liver to make extra cholesterol or to slow their bodys cholesterol removal process. If youve inherited these genes, you may have high cholesterol even if you dont eat foods that are rich in fat or cholesterol.

  • your activity level
HDL good cholesterol >60 mg/dL

Your doctor will likely still check your HDL, LDL, and total cholesterol levels with a blood test called a lipoprotein panel.

If your cholesterol is high, you can start taking steps to lower it with lifestyle changes and possibly medication.

If your cholesterol level is high, you may be able to successfully manage it with a few lifestyle changes.

How To Increase Hdl Cholesterol

Although HDL levels are driven by family genetics, you can improve HDL levels in three key ways:

  • If you are a smoker, research clearly shows that quitting smoking can increase HDL.
  • Adopting a heart-healthy diet low in fat and high in fiber can also modestly raise your HDL.
  • Aerobic exercise can also have positive effects on HDL. Have trouble exercising? Find a buddy; research shows it helps motivate you. That exercise can be as simple as increasing the amount of walking you do each week.

Lastly, although primarily used to decrease high LDL, some statin medications may potentially increase HDL levels moderately. Any medical treatment option should be discussed with your doctor. Importantly, high HDL does not protect you from the untoward effects of high LDL.

What Does Cholesterol Have To Do With Diabetes

If you are someone with type 1 or type 2 diabetes, it is important to be proactive about your cholesterol, especially if you dont have stable glucose levels. People living with diabetes are more likely to be at risk for heart disease and stroke, especially at a young age, so its important to be as proactive as possible to keep your heart healthy.

Compared to people without diabetes, people with diabetes are more likely to experience lower levels of HDL and higher levels of LDL cholesterol. This means that there is not enough good cholesterol which normally helps to reduce your bad cholesterol ;to effectively do its job. Thats why its especially important for people with diabetes to monitor HDL and LDL levels and adopt healthy habits including diet and exercise to avoid health complications that could arise. The dangerous combination of low HDL and high LDL can lead to a greater risk of coronary heart disease over time.

Tips For Managing Your Cholesterol

Switch out processed and refined grains for whole grains. ;Dietary fiber is critical for promoting healthy cholesterol in the body, but refined grains are stripped of fiber when processed. Consuming whole grains has been shown to improve blood cholesterol levels and lower your risk of heart disease, stroke, and obesity.

  • Foods like pasta and bread are available in whole wheat or whole grain versions which have high levels of dietary fiber. These kinds of swaps are tasty and helpful for lowering cholesterol levels.

  • Chips, crackers, and sugary cereal should be limited though you can try whole grain options made with oats, seeds, quinoa, flax, or lentils.

  • When reading a foods nutrition label, look for a list of simple whole grain ingredients other than white flour.

  • The American Heart Association suggests that adults aim for about 25 grams of fiber per day, though your healthcare professional may suggest more or less.

Make sure youre eating vegetables and fruits with every meal. Vegetables and fruits contain vitamins and nutrients that your body needs, in addition to more fiber.

Avoid saturated and trans fats. Saturated fats differ from healthier unsaturated fats because they are usually solid at room temperature .

Use healthy oils. Healthy oils are low in saturated fat and instead contain unsaturated fat.

How Much Alcohol Is Safe To Drink

How To Lower Your Bad Cholesterol

To stay in good health and avoid illness, the government recommends drinking no more than 14 units of alcohol per week, for men and women. To keep the risks down:

  • spread your units out across the week
  • have some alcohol-free days
  • avoid drinking more than six units in six hours, which counts as binge drinking thats less than three 175ml glasses of wine or three pints of beer.

If you have high cholesterol or FH, it should be OK to drink alcohol within these limits. There are some health problems and treatments which can mean its safer to avoid alcohol all together. Speak to your doctor or nurse about whats safe for you.

In the past, it was thought that drinking in moderation was good for your heart. Its now believed that the only possible benefits are for women over 55 when drinking 5 units a week or less, and the benefits are modest.

We dont recommend drinking alcohol to improve your health, as you will improve your health more by eating well and being active. With alcohol, the cons could out way the pros.

How much is a unit of alcohol?

A unit of alcohol is roughly the amount your body can clear from your blood in one hour. Its the equivalent of 10ml or 8g of pure alcohol.

Different drinks contain different amounts of alcohol, as some are stronger than others. For example, a 175ml glass of wine can contain anywhere between 1.9 and 2.4 units. It can be surprising how many units are in your favorite drinks, and how quickly they add up.

14 units is roughly:

Argument 4: Statins Dont Work For Primary Prevention

The US Preventive Services Task Force disagrees with this point. There have actually been many studies looking at statins in primary prevention . The benefit in primary prevention is certainly less than in secondary prevention, but the benefit is still there.

Figure 4 from: Association Between Lowering LDL-C and Cardiovascular Risk Reduction Among Different Therapeutic Interventions A Systematic Review and Meta-analysis JAMA. 2016;316:1289-1297. doi:10.1001/jama.2016.13985

As the above graph shows, even in primary prevention, if you lower LDL, you lower cardiovascular risk. The magnitude of that benefit is smaller than in secondary prevention, and you might decide that benefit is too small to justify starting a new medication. As always, higher risk patients benefit most from medications. But the claim that statins have no benefit whatsoever is incorrect.
