Cholesterol And The Great Egg Debate
One source of confusion has long been eggs. A typical egg contains about 200 milligrams of cholesterol, but only 1.5 grams of saturated fat. When researchers first linked high bloodcholesterol levels to heart disease, eggs got a bad rap.
But there’s never been good evidence that eggs are a major factor in high blood cholesterol levels or a contributing cause of heart disease.
In fact, when researchers at Harvard Medical School analyzed data from almost 120,000 men and women, they found that eating the equivalent of an egg a day did not increase the risk of heart disease or stroke. A more recent Harvard Medical School study, published in 2008, also found that otherwise healthy men could eat up to seven eggs a day with little risk. The only danger showed up in men with diabetes, which is known to increase heart disease risk.
Indeed, studies suggest that only about 30% of people are particularly susceptible to the effects of dietary cholesterol on blood cholesterol levels.
And overall, the effects of dietary cholesterol are relatively small compared with saturated fat and trans fats.
In a review of studies in which volunteers were fed eggs, researchers found that lowering the amount of dietary cholesterol by 100 milligrams a day resulted in only a 1% reduction in blood cholesterol levels. Replacing saturated fat with unsaturated fat had a much more beneficial effect on cholesterol.
What Does 100% Of Your Daily Value Of Cholesterol Look Like
Its no secret that eating fatty foods raises your bad cholesterol level, also known as LDL. An elevated LDL clogs up your arteries and makes it difficult for your heart to do its job. Potentially, it could lead to heart disease.
The USDA recommends consuming no more than 300 mg of cholesterol a day. While a deep-fried Twinkie at the county fair is an obvious no-no, other high cholesterol culprits may be sneaking into your diet. Check out what that number looks like in terms of everyday food items.
Warning: you may need to revise your grocery listand your eating habits!
The USDA recommends no more than 300 mg of cholesterol a daybut thats not a number you should strive for. Saturated and trans fats are not part of a balanced diet. You should limit them as much as possible.
Replace saturated and trans fats with healthy fats, such as those found in mono- and polyunsaturated fat food sources. For example, cook with olive oil instead of butter. Drink fat-free milk instead of whole. Eat more fish and less red meat.
Cholesterol Content Of Foods
If you have risk factors for heart disease, you should not consume more than 200 milligrams of cholesterol a day.
If you do not have risk factors for heart disease, you should limit your cholesterol intake to no more than 300 milligrams a day.
Use the following tables to check the cholesterol and fat content of the foods you eat. This will help you keep track of your daily cholesterol intake.
Note: Cholesterol is only found in animal products. Fruits, vegetables, grains and all other plant foods do not have any cholesterol at all.

Foods High In Fiber Low In Saturated Fat Can Lower Cholesterol
While saturated fat and dietary cholesterol both play a role in your cholesterol level, experts stress that the most important dietary change you can make to lower your cholesterol numbers is to adjust the overall pattern of your diet. Best is a diet rich in fruits, vegetables, fish, and whole grains. This helps in two ways. First, the more of these healthful foods you eat, the less you generally consume of foods that are high in saturated fat and highly refined carbohydrates, which both damage the cardiovascular system. Second, high-fiber foods help reduce your cholesterol level by making unhealthy dietary fats harder to absorb from the gut.
This doesn’t work for everyone, however. For people at high risk of heart disease, dietary efforts don’t come close to lowering cholesterol enough. Other people are genetically predisposed to having high blood cholesterol regardless of what they eat.
Do I Need To Cut Down On Dietary Cholesterol
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.

Understanding The Amounts Of Cholesterol And Fats Found In Foods
Here are some examples of foods and approximately how much cholesterol and fats you can find in each:
| Food | |
| 1/4 lb. 95% lean ground beef | 70 mg |
| 1/4 lb. 70% lean ground beef | 88 mg |
| 6 oz. skinless chicken breast | 124 mg |
| 1 tbsp. extra virgin olive oil | 0 mg |
| 1 cup vanilla ice cream | 58 mg |
| 0 g | 28.1 g |
All of the above values come from the USDAs National Nutrient Database. These are just some examples of the relative amounts of cholesterol and fats found in your food.
Tips
- Pay attention to the saturated and trans fats on your food labels, as well as added sugars. The less of these you consume, the better. No more than 10 percent of your daily calories should come from either saturated fats or added sugars.
- Dont worry about eating enough cholesterol. Your body makes enough whether or not you consume it.
- Eat more healthy, unsaturated fats. Try replacing butter with extra virgin olive oil in cooking, buy lean cuts of meat, and snack on nuts and seeds instead of french fries or processed snack foods.

Tips For Adding More Healthy Fats To Your Diet
Instead of obsessively counting fat grams, aim for a diet rich in a variety of vegetables, fruit, nuts, and beans, with two or more weekly servings of fatty fish, moderate amounts of dairy, small amounts of red meat, and only occasional fried or processed meals.
This might mean replacing fried chicken with grilled chicken, swapping out some of the red meat you eat with other sources of protein such as fish, chicken, or beans, or using olive oil rather than butter. Following a Mediterranean diet can also help ensure youre getting enough good fats in your diet and limiting the bad ones.
Limit your intake of saturated fats by replacing some of the red meat you eat with beans, nuts, poultry, and fish, and switching from whole milk dairy to lower fat versions. But dont make the mistake of replacing saturated fat with refined carbohydrates and sugary foods.
Eat omega-3 fats every day. Include a variety of fish sources as well as plant sources such as walnuts, ground flax seeds, flaxseed oil, canola oil, and soybean oil.
Cook with olive oil. Use olive oil for stovetop cooking rather than butter, stick margarine, or lard. For baking, try canola oil.
Eat more avocados. Try them in sandwiches or salads or make guacamole. Along with being loaded with heart- and brain-healthy fats, they make for a filling meal.
Reach for the nuts. You can add nuts to vegetable dishes, use them instead of breadcrumbs on chicken or fish, or make your own trail mix with nuts, seeds, and dried fruit.
The Problem With Too Much Cholesterol
Dietary cholesterol comes primarily from sources of saturated fats, like meat and other animal-based products.
The double-whammy with cholesterol is that by eating a diet high in saturated fat intake, you consume more cholesterol, and these foods make your liver produce more cholesterol, too! This increased production and consumption turns into high cholesterol levels in the body pretty quickly.

Myth: All Cholesterol Is Bad For You
Fact: Some types of cholesterol are essential for good health. Your body needs cholesterol to perform important jobs, such as making hormones and building cells. Cholesterol travels through the blood on proteins called lipoproteins. Two types of lipoproteins carry cholesterol throughout the body:
- LDL , sometimes called bad cholesterol, makes up most of your bodys cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke.
- HDL , or good cholesterol, carries cholesterol back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.
When your body has too much LDL cholesterol, it can build up in the walls of your blood vessels. This buildup is called plaque. As your blood vessels build up plaque over time, the insides of the vessels narrow. This narrowing can restrict and eventually block blood flow to and from your heart and other organs. When blood flow to the heart is blocked, it can cause angina or a heart attack.

Treatment may include:
-
Addressing risk factors. Some risk factors that can be changed include lack of exercise and poor eating habits.
-
Cholesterol-lowering medicines. Medicines are used to lower fats in the blood, particularly LDL cholesterol. Statins are a group of medicines that can do this. The two most effective types are atorvastatin and rosuvastatin. Other medicines that lower cholesterol levels are ezetimibe and PCSK9 inhibitors.

Lowering Cholesterol With Weight Loss
If you could stand to lose a few pounds, probably the most important number to check on the label is calories per serving.
A recent study by researchers at the University of Surrey in England showed that when volunteers cut back on calories, it didn’t matter how much dietary cholesterol they consumed. Even when their diets contained up to 582 milligrams of cholesterol a day — far over the recommended amount — their blood cholesterol levels remained unchanged as long as they cut back on calories and lost weight.
“Cholesterol in packaged foods really isn’t a big issue,” says McManus. “Three much more important numbers on the nutrition facts panel are serving size, calories per serving, and the type of fats,” says McManus. “If you keep track of those, you don’t have to worry about how much cholesterol a packaged food contains.”

Heart-healthy lifestyle changes include a diet to lower your cholesterol. The DASH eating plan is one example. Another is the Therapeutic Lifestyle Changes diet, which recommends that you
Choose healthier fats.You should limit both total fat and saturated fat. No more than 25 to 35% of your daily calories should come from dietary fats, and less than 7% of your daily calories should come from saturated fat. Depending upon how many calories you eat per day, here are the maximum amounts of fats that you should eat:
| Calories per Day | |

Saturated fat is a bad fat because it raises your LDL level more than anything else in your diet. It is found in some meats, dairy products, chocolate, baked goods, and deep-fried and processed foods.
Trans fat is another bad fat it can raise your LDL and lower you HDL . Trans fat is mostly in foods made with hydrogenated oils and fats, such as stick margarine, crackers, and french fries.
Instead of these bad fats, try healthier fats, such as lean meat, nuts, and unsaturated oils like canola, olive, and safflower oils.
Limit foods with cholesterol. If you are trying to lower your cholesterol, you should have less than 200 mg a day of cholesterol. Cholesterol is in foods of animal origin, such as liver and other organ meats, egg yolks, shrimp, and whole milk dairy products.
Eat plenty of soluble fiber. Foods high in soluble fiber help prevent your digestive tract from absorbing cholesterol. These foods include:
Theres A Lot Of Conflicting Information About Saturated Fats Should I Eat Them Or Not
The American Heart Association recommends limiting saturated fats which are found in butter, cheese, red meat and other animal-based foods. Decades of sound science has proven it can raise your bad cholesterol and put you at higher risk for heart disease.
The more important thing to remember is the overall dietary picture. Saturated fats are just one piece of the puzzle. In general, you cant go wrong eating more fruits, vegetables, whole grains and fewer calories.
When you hear about the latest diet of the day or a new or odd-sounding theory about food, consider the source. The American Heart Association makes dietary recommendations only after carefully considering the latest scientific evidence.

Cholesterol And Heart Disease: The Role Of Diet
Your diet clearly plays a role in determining your cholesterol levels, but if you’re like most people, the most important factor isn’t how much cholesterol-rich food you eat. Rather, it’s what else you eat. Figuring this out has been a learning process.
Initially, the news that cholesterol in the bloodstream was linked to heart disease prompted an all-out war on cholesterol in food. From the 1960s on, people were advised to stay away from foods rich in cholesterol, like eggs, dairy foods, and some types of seafood. But today, the science suggests that, for most people, dietary cholesterol has only a modest effect on the amount of cholesterol in the bloodstream. In fact, the 20152020 Dietary Guidelines for Americans eliminated an earlier recommendation to limit dietary cholesterol to 300 milligrams per dayalthough they still suggest caution on overall intake.
Notably, the guidelines did not change the recommendation on saturated fat, which is found mainly in animal-based foods such as meat and dairyand is often found in high-cholesterol foods. Saturated fat in the diet clearly does raise LDL by a significant amount and should still be consumed in limited quantities. And although some research has cast doubt on the conventional wisdom that saturated fat is linked with heart disease, other research upholds the link.
Overall Dietary Cholesterol Intake
Based on 2013 to 2014 NHANES survey cycle data, the estimated national population-level mean dietary cholesterol intake among adults 20 years of age or older was 293 mg/day , and the mean cholesterol density was 137 mg cholesterol per 1000 kcal energy intake . In 20132014, a total of 39% adults had dietary cholesterol intake above 300 mg/day . Compared to women, men had significantly higher total cholesterol intake and higher cholesterol density . A trend of decreased cholesterol intake with increased age was observed , but cholesterol density did not differ by age groups . Among the race-ethnicity groups, Mexican Americans had the highest cholesterol intake and highest cholesterol density, while Non-Hispanic whites consumed the least amount of cholesterol and had the lowest cholesterol density .
