Why This Study Is Flawed
When I asked Ethan Weiss, M.D., cardiologist and associate professor at U.C. San Franciscoâs Cardiovascular Research Institute, if this studyâs findings were enough to consider revising our dietary guidelines to reinstate a cholesterol cap, his response was an emphatic no. In fact, when he first heard about this new study, he recalls that his response was âsome sort of expletive-laced rant about how I canât believe weâre having this conversation again.â
The first problem with this study, says Dr. Weiss, is that itâs an observational study. Nutritional epidemiology, in which researchers observe and examine the eating habits and health outcomes of a population over time, has long been criticized for its inability to measure diet accurately, and for the tendency of these studies to yield conflicting results.
âPlenty of people much smarter than me have written eloquently about the idea that nutritional epidemiology is just kind of garbage,â he says. âItâs basically a tarot card reading you can see whatever you want in these results. But it gets a lot of attention, and as long as people keep reacting to it the way they have been, weâre going to keep seeing it.â
And other experts agree: âThese findings shouldnât necessarily scare anyone away from eggs, given that the increase in risk associated with eating eggs was really minimal,â says neuroscientist and integrative nutritionist Lisa Mosconi, Ph.D.
Does Hard Boiled Eggs Cause High Blood Cholesterol
If you are already experiencing troubles lowering your blood cholesterol levels, then it is just better to avoid eating too much egg no matter how you cook them whether omelets or hard boiled eggs to avoid a spike in your blood cholesterol levels and other heart diseases, some people believe that the way you cook your egg can reduce its high cholesterol content, there is a myth widely believed that hard boiling eggs reduce the high cholesterol content in egg than any other cooking method, however that is not really true, one large hard boiled egg was found to contain the same amount of dietary cholesterol as one large raw egg.
How Much Cholesterol In Egg.
One large hard boiled egg approximately contain 186 milligrams of dietary cholesterol while one large scrambled egg contain approximately 170 milligrams of dietary cholesterol, doctors recommend a daily allowance of 300 milligrams of dietary cholesterol per day in order to prevent high blood cholesterol levels and reduce the risk of heart diseases.

Are Eggs Good For You
According to Keck Medicine of USC, eggs can be a staple source of protein in any diet. They contain decent amounts of vitamins, A, B5, B6, B12, D, E, and K, as well as folate, phosphorus, selenium, riboflavin, and zinc. Eggs also contain calcium, which can improve bone health.
The high levels of protein content in eggs will also help keep you full for longer and a hard-boiled egg might help keep you going throughout the day. According to Today, the antioxidants in egg yolks might even help reduce the risk of macular degeneration, cataracts, and several other age-related conditions.

What Happens When People Eat Several Whole Eggs Per Day
For many decades, people have been advised to limit their consumption of eggs or at least of egg yolks.
A single medium-sized egg contains 186 mg of cholesterol, which is 62% of the recommended daily intake . In contrast, the white is mostly protein and low in cholesterol .
Common recommendations include a maximum of 26 yolks per week. However, scientific support for this limitation is lacking .
A few studies have examined the effects of eggs on cholesterol levels.
These studies divided people into two groups one group ate 13 whole eggs per day while the other ate something else, such as egg substitutes.
These studies show that:
It appears that the response to eating whole eggs depends on the individual.
In 70% of people, eggs had no effect on total or bad LDL cholesterol. However, in 30% of people called hyper-responders these markers do go up slightly .
Although eating a few eggs per day may raise blood cholesterol in some people, they change the bad LDL particles from small and dense to large .
People who have predominantly large LDL particles have a lower risk of heart disease. So even if eggs cause mild increases in total and LDL cholesterol levels, its not a cause for concern .
The science is clear that up to 3 whole eggs per day are perfectly safe for healthy people.

The Importance Of Other Food Along With Eggs
It is important to consider other foods that feature in your daily diet along with eggs. Often times eggs are a breakfast food and are paired with white bread, sausages and butter. This type of egg breakfast definitely increases your cholesterol intake and you should consider healthier options instead of sausages, white bread and butter. If you are eating an egg for breakfast and fried chicken wings for dinner you have probably exceeded your daily limit of cholesterol intake. Hence it is important to be calculative about your cholesterol intake when planning your daily meals. Even if eggs are largely safe in terms of cholesterol intake you are not doing yourself any favors by combining eggs with other cholesterol rich foods.

No Link To Heart Disease
On top of cholesterol’s effects on the body, a 2018 study published in the journal Heart suggests that people who eat eggs aren’t any worse off than those who don’t. Moreover, the study failed to find a connection between one-a-day egg consumption and heart disease, even in people whose genetics put them at higher-than-normal risk.
According to the study, eggs may even have a protective effect. People who reported eating up to one egg per day had an 11% lower risk of developing heart diseaseand an 18% lower risk of dying from itthan those who did not eat eggs. They also had a 26% lower risk of having a hemorrhagic stroke when ruptured blood vessels cause bleeding in the brain.
Dr. Schulman said the study’s findings aren’t surprising and are further evidence that eggs aren’t bad for you. “I’ve been preaching this for a while,” Dr. Schulman said. “This is more good news.”
Do You Have High Cholesterol
Cholesterol is a fat-like substance that is a natural and essential part of all cells in your body. It helps produce hormones, make vitamin D, provide cells with structure, and plays a role in the process of digesting fats. The liver creates all of the cholesterol that your body needs, so it is not required that you get it from foods. Foods that come from animals such as meat, cheese, and eggs all provide dietary cholesterol to the body.
There are two types of cholesterol: high-density lipoproteins and low-density lipoproteins . HDL is thought of as the good type of cholesterol because it carries cholesterol from your blood to your liver to be removed. This is helpful to the heart. LDL is the bad type of cholesterol: It causes a buildup of cholesterol in the blood, which leads to furring up of the arteries. This is called atherosclerosis and is a direct cause of heart attacks, strokes, and peripheral artery disease.
Triglycerides are a type of fat in the blood. They are separate to and different from cholesterol, but they are nearly always included in the cholesterol lab panel since they have a similar effect on your heart and overall health. Triglycerides come from eating too many calories . These extra calories are stored in the blood as triglycerides. High triglyceride levels can lead to heart disease and problems in your pancreas and liver, including fatty liver disease.
Here are the normal ranges for cholesterol and triglyceride levels in adults :
Why Is High Cholesterol Bad
Cholesterol is a type of lipid, which is a waxy substance that forms an important part of your bodys cells. While cholesterol is essential to our bodies, having too much of it in the bloodstream can increase the risk of heart disease.
High cholesterol levels can lead to fatty deposits building up in blood vessels which eventually makes it difficult for blood to flow around the body. These deposits can break off and form clots that may cause a heart attack or stroke.
High cholesterol levels can be caused by genetics but is also commonly caused by unhealthy diet and lifestyle choices. So while you cant change your genetics, many people can lower their cholesterol levels by eating a healthy diet and exercising regularly.
In the past, some dietary experts did recommend limiting dietary cholesterol and egg intake. But as health and nutrition research has continued and our understanding of diet has improved, healthy eating guidelines now state that dietary cholesterol have a minimal impact on blood cholesterol levels in most people.
Do Eggs Affect Your Cholesterol
One of the biggest debates about eggs is how eating them impacts your cholesterol. Some studies have found dietary cholesterol in eggs doesnt really affect cholesterol levels. Thats righteating cholesterol may not raise your cholesterol levels.1
A much more likely culprit for high blood cholesterol levels is the saturated fat in your diet. Is it possible that cholesterol consumption may increase blood cholesterol levels? Yes. But its possible that people with more cholesterol in their diets eat more saturated fats and other unhealthy foods.
Hdl Vs Ldl Cholesterol
If youre concerned about eating eggs, you might be wary of your own cholesterol levels. Now, there are two different types of cholesterol in the blood one good and one bad.
The problem with cholesterol is that it can accumulate in the arteries. This impedes blood flow, increasing the risk of heart issues. LDL cholesterol causes this build-up. When LDL levels are too high, it can pose a serious health risk.
HDL cholesterol has a positive effect. It helps wash LDL cholesterol from your bloodstream. This helps your body to get rid of dangerous LDL of it before it builds up in your arterial walls.3If you want to eat to balance your cholesterol and keep levels healthy, your best bets are:
- Consuming fatty fish
- Reducing your sugar and alcohol intake
Can I Eat Eggs
People with raised cholesterol often wonder if its OK to eat eggs, as egg yolk is rich in cholesterol. Generally speaking, it should be fine for most people, as the cholesterol in eggs does not have a significant effect on blood cholesterol.
Its much more important to limit the amount of saturated fat you eat. Too much saturated fat can raise the cholesterol in your blood. So, most people can eat eggs as long as they are part of a healthy diet that is low in saturated fat.
If you have high blood cholesterol, you should limit the amount of cholesterol you eat to about 300mg per day. Thats about the amount most people in the UK eat. Eating three to four eggs a week should be fine, but speak to your doctor or dietitian about whats best for you.
If you have familial hypercholesterolaemia, you should also limit your dietary cholesterol to 300mg a day, but it is probably better to aim for nearer 200 mg on average.
Eggs Are Packed With Nutrients And Protein
“There are a lot of great reasons to eat eggs,” said Dr. Schulman. According to the USDA, one large raw egg contains:
- 6.30 grams of protein
- 0.53 milligrams of vitamin E
- 2.05 micrograms of vitamin D
- 0.02 milligrams of folate
These nutrients each play an important role. According to MedlinePlus, protein helps to make and repair the cells in your body. According to the National Institutes of Health, choline is an essential nutrient that helps with memory, mood, and muscle control. Vitamin E protects your cells from damage, while vitamin D helps to build bones and fight infection, according to the Nemours Foundation. Lastly, folate is vital for making red blood cells, according to Johns Hopkins Medicine.
“If you eat a breakfast that’s only high in carbohydrates and no protein, you’re going to be hungry again very quickly,” Dr. Schulman said.
Instead, Dr. Schulman recommended choosing high-fiber carbohydrates and adding an egg or two for staying power.
Bad And Good Cholesterol
Because it is a fatty substance, it doesnt dissolve in water and cannot move freely with the blood. To gain mobility, it must combine with special proteins, thus forming the LDL and HDL compounds.
LDL is necessary, it carries cholesterol from the liver to the organs ad cells that require it, and HDL returns the excess to the liver. In recent years, it has been established that a high HDL level is not always positive several additional factors must be considered.

What The Surveys Say
In survey research, it is common to see a relationship between egg consumption and dietary cholesterol. A meta-analysis of 17 studies with sample sizes ranging from 9 to 79 noted that HDL, LDL, and total cholesterol all increased in most studies, and that the HDL:LDL and HDL:cholesterol ratios both tended to worsen. Some of the studies investigated in this meta-analysis were mentioned in the previous section.
Various recent surveys and reviews have shown little to no correlation between egg consumption and risk for cardiovascular disease. Whereas a prospective study of 3,898 men and women reported that egg consumption or dietary cholesterol didnt seem to increase the risk of incident diabetes, one sub-group analysis might suggest a link between egg consumption and a slightly increased risk of cardiovascular disease in people who are already diabetic.
Some studies link egg consumption to an increase in cholesterol levels some do not but no study has shown an increase in risk of cardiovascular disease.
How Your Body Regulates Cholesterol Levels
Cholesterol is often viewed as negative.
This is because some studies have linked high levels of cholesterol with heart disease and early death. However, the evidence is mixed .
The truth is that cholesterol plays a very important function in your body. Its a structural molecule that is essential to every cell membrane.
It is also used to make steroid hormones like testosterone, estrogen and cortisol.
Given how important cholesterol is, your body has evolved elaborate ways to ensure that it always has enough available.
Because getting cholesterol from the diet isnt always an option, your liver produces enough to meet your bodys needs.
But when you eat a lot of cholesterol-rich foods, your liver starts producing less to keep cholesterol levels from becoming excessively high .
Therefore, the total amount of cholesterol in your body changes only very little, if at all. What changes is its source your diet or your liver (
Summary Your liver produces large amounts of cholesterol. When you eat cholesterol-rich foods such as eggs, your liver compensates by producing less.
Eating Eggs The Smart Way
Keep in mind that everyone’s nutrition needs are different, so de Souza says that although eggs are not an issue for most people, “if a reputable health professional â meaning a doctor who doesn’t sell diet books, or a registered dietitian â has told you to avoid eggs because you have a genetic tendency to high cholesterol, you should follow her or his advice.”
And don’t forget the egg whites â hard-boiled or otherwise. As the Harvard School points out, egg whites, which are 100 percent cholesterol-free, could be a smart way to go if you are concerned about your LDL levels.
To safeguard your heart, Harvard experts also urge egg lovers to steer clear of all those heart-âunâhealthy extras â think cheese, sausage, home fries and white toast â that might turn an otherwise healthy egg dish into a fully loaded unhealthy meal.
Avoiding Cholesterol In Food Foods High In Cholesterol
So, now that you know what to eat, what foods should you avoid?
Here is a list of foods high in cholesterol:
- Meat Any meat that contains saturated fat will be converted into the LDL cholesterol which will stick to the walls of your arteries. Eat lean or cut out meat altogether.
- Dairy Full fat dairy contains all the saturated fat that you can find in meat, so you should always try to eat non or low fat dairy products.
- Sugar Anything that is sweet contains sugar, and sugar is turned into cholesterol very quickly. If it has to have sugar added to it, it probably means that it shouldnt be going into your mouth.
- Fried Foods Food that has been fried tends to contain a lot of trans fats from the frying process, and most of the fried foods that you eat will be meats . Try to avoid all fried and deep fried foods.
These are the worst of the foods high in cholesterol, but it is always best to avoid foods that contain sugar, oil, or fat unless theyre the natural fats found in e.g. nuts, oats, and avocadoes.
