How The Fat You Eat Affects Cholesterol Levels
The relationship between the fat we eat and our health, particularly our cardiovascular health, has been hotly debated for many years.
Heres what you need to know:
Not all fats are created equally.
The kinds of fat you eat matter more than the amount.
There are different types of fats in our diet:
-
Polyunsaturated fats: essential and important nutrients
-
Monounsaturated fats: can come from plant or animal products and are generally considered healthy
-
Saturated fats: less healthy than mono- and polyunsaturated fats
-
Trans fats: unhealthy fats
Unhealthy Or Bad Fats
Trans fat. Small amounts of naturally occurring trans fats can be found in meat and dairy products but its artificial trans fats that are considered dangerous. This is the worst type of fat since it not only raises bad LDL cholesterol but also lowers good HDL levels. Artificial trans fats can also create inflammation, which is linked to heart disease, stroke, and other chronic conditions and contributes to insulin resistance, which increases your risk of developing Type 2 diabetes.
In the U.S., the Food and Drug Administration has effectively outlawed the use of artificial trans-fats in commercially prepared food and the World Health Organization has called on other governments around the world to eliminate the use of trans fats by 2023. However, products made before the FDA ban may still be available for sale. Since products can be listed as having zero trans fats even if they contain up to 0.5 grams of trans fat per serving, its still important to carefully read food labels. Look for ingredients referred to as partially hydrogenated oils. These hidden sources of artificial trans fats can add up quickly.
If your country still allows the use of artificial trans fats, remember that no amount is considered safe, so aim to eliminate it from your diet.
Trans fat primary sources include:
Saturated fat primary sources include:
- Red meat
- Chicken skin
- Whole-fat dairy products
- Butter
- Tropical oils such as coconut and palm oil
Recommended Dietary Fat Saturated Fat And Cholesterol Intakes
High dietary fat, saturated fat, and cholesterol intakes are associated with increased risk for many diseases. The Dietary Reference Intakes recommends a diet low in saturated fat, trans fat, and cholesterol and one which provides 20 to 35 percent of the daily calories intake from fat. The top end of this range is slightly higher than previous recommendations. This revision recognizes that diets with up to 35 percent of calories from fat can be compatible with good health if calorie intake is reasonable and saturated fat intake is low. The Dietary Guidelines recommendations for fat intake are:
- Consume less than 10 percent of calories from saturated fatty acids and less than 300 mg/day of cholesterol, and keep trans fatty acid consumption as low as possible.
- Keep total fat intake between 20 to 35 percent of calories, with most fats coming from sources of polyunsaturated and monounsaturated fatty acids, such as fish, nuts, and vegetable oils.
- When selecting and preparing meat, poultry, dry beans, and milk or dairy products, make choices that are lean, low-fat, or fat-free.
- Limit intake of fats and oils high in saturated and/or trans fatty acids, and choose products low in such fats and oils.

A List Of 10 High Cholesterol Foods
1. Butter
Butter is hydrogenated fat and high in cholesterol.
2. Sausage
Sausage is often made from the fattiest parts of the pig, so, while all meat contains cholesterol, sausage is especially high in cholesterol.
3. Egg Yolks
The yolk of an egg is very high in cholesterol. However, there is new evidence to suggest that our bodies do not absorb the cholesterol in eggs the way they do that of meat, so eggs may not be so bad for you after all. Watch health news for more information on eating eggs.
4. Caviar
Caviar, sometimes called fish roe, is a popular spread on bread in Europe. But these tiny fish eggs are full of cholesterol.
5. Liver Pate
All organ meats are much higher in cholesterol than meats from other parts of an animals body.
6. Oil Packed Fish
If youre choosing canned fish, like tuna and sardines for their healthy Omega 3s, be certain youre not choosing those packed in oil. The oil that the fish is packed in is high in cholesterol, defeating any benefit you get from eating the fish.
7. Cheese
Some cheeses are higher in cholesterol than others. Choose low fat cheeses for a good calcium and protein boost. Stay away from Port de Salut, the cheese highest in cholesterol.
8. Processed Meats
Lunch meats and processed meats like bacon tend to be high in cholesterol because they are not made from the leanest cuts of meat.
9. Fast Food
10. Shellfish
Oysters, clams, mussels and shrimp are quite high in cholesterol.
Foods from animals are generally high in cholesterol
Which Foods Are High In Cholesterol
All animal foods contain some cholesterol. But by cutting down on the animal foods that contain saturated fats you will be keeping the cholesterol in your diet in check too.
Foods that contain cholesterol and are high in saturated fat. |
Full fat dairy foods such as milk, cheese, yogurt and cream. |
Animal fats, such as butter, ghee, margarines and spreads made from animal fats, lard, suet and dripping. |
Fatty meat and processed meat products such as sausages. |
There are some foods which are low in saturated fat but high in cholesterol. These include eggs, some shellfish, liver, liver pate and offal. Most people dont need to cut down on the cholesterol thats found in these foods.
Foods that contain cholesterol but are low in saturated fat. |
Lean meat, especially offal, such as liver, kidney, sweetbreads, heart and tripe |
Prawns, crab, lobster, squid, octopus and cuttlefish. |
Eggs . |
For people with FH, or who have high cholesterol, or are at high risk of or have cardiovascular disease, you can still eat some of these foods, but you need to be more careful about how often you eat them to ensure youre keeping within the guidelines. For example, you could eat three or four eggs a week, and shellfish such as prawns up to once or twice a week.
You should avoid liver and offal altogether because they are very rich sources of cholesterol.

Dietary Fat And Cholesterol
Dietary fat plays a major role in your cholesterol levels. Cholesterol is a fatty, wax-like substance that your body needs to function properly. In and of itself, cholesterol isnt bad. But when you get too much of it, it can have a negative impact on your health. As with dietary fat, there are good and bad types of cholesterol.
- HDL cholesterol is the good kind of cholesterol found in your blood.
- LDL cholesterol is the bad kind.
- The key is to keep LDL levels low and HDL high, which may protect against heart disease and stroke.
- Conversely, high levels of LDL cholesterol can clog arteries and low HDL can be a marker for increased cardiovascular risk.
Rather than the amount of cholesterol you eat, the biggest influence on your cholesterol levels is the type of fats you consume. So instead of counting cholesterol, its important to focus on replacing bad fats with good fats.
How Is Cholesterol Measured
Most people with high cholesterol feel perfectly well and often have no symptoms. The best way to find out if your cholesterol is high is to have a blood test .
Visit your GP to determine whether you need to lower your cholesterol level and what action to take.
GPs can also do a heart health check, that calculates your heart disease and stroke risk.

Cholesterol and fats
Cholesterol is classified into two groups, based on the type of protein that transports it through the bloodstream:
- LDL cholesterol, which is cholesterol carried by low-density lipoproteins, is dropped off for use throughout the body. Because this kind of cholesterol is prone to building up, it is often referred to as bad cholesterol.
- HDL cholesterol, which is cholesterol carried by high-density lipoproteins, works together with its protein counterpart like a garbage truck, collecting extra bad cholesterol from the arteries and bringing it back to the liver to be disposed of. For this reason, it’s referred to as good cholesterol.
Types of Fat
The goal is to eat a diet that promotes low levels of bad cholesterol and high levels of good cholesterol. Fat intake affects this balance because fatty acids bind to liver cells and regulate the production of cholesterol.
Each form of fat influences cholesterol levels differently so it is important to pay attention to the types of fat consumed:
Foods to avoid
The American Heart Association advises reducing saturated fat intake to no more than 5 to 6 percent of the total daily calories. To do this, they suggest limiting the following foods:
- fatty beef
- dairy products made from whole or reduced-fat milk
- saturated vegetable oils, such as coconut oil, palm oil, and palm kernel oil
It is also important to avoid trans fats. Foods to stay away from include:

Foods That Lower Your Cholesterol
Some foods can actively help to lower your cholesterol and they all work in different ways. Try to include these foods in your meals whenever you can:
1. Oats and barley
Eating whole grain foods reduces your risk of heart disease. Oats and barley are extra special because they are high in a type of soluble fibre called ‘beta glucan’. Beta glucan helps to lower ‘bad’ LDL cholesterol in your blood2,3.
Tip: Flavoured oat products like ‘Quick Oats’ often contain added salt and/or sugar. Choose products that contain 100% oats as they’re closest to how theyre found in nature.
2. Vegetables and fruit
Eating a variety of colourful vegetables and fruit everyday can help protect you against heart disease, stroke and some cancers4,5. Many vegetables and fruit are high in soluble fibre which helps to reduce the absorption of cholesterol and lower ‘bad’ LDL cholesterol in your blood.
Tip: Leave the skins on vegetables like pumpkin, kmara and carrot to maximise your intake of fibre. Use orange and lemon peel in dressings and sauces.
3. Foods rich in heart-healthy fats
Eating plenty of foods that contain heart-healthy mono and poly-unsaturated fats increases the levels of ‘good’ HDL cholesterol in your blood.
These foods contain heart-healthy fats.
- Avocado
- Olives
- Vegetable oils and spreads
Eating these foods instead of foods high in saturated fat improves your cholesterol. Itll reduce your risk of heart disease too6.
4. Legumes and beans
5. Nuts
6. Soy products
7. Plant sterols
Why You Should Avoid Cholesterol
Cholesterol circulates throughout the bloodstream, and too much of it can have negative effects on your body, especially your heart. High levels of “bad” cholesterol can raise your risk of heart disease or stroke.
When you have too much LDL cholesterol in your system, it can form plaque, which is a buildup on the walls of the blood vessels. This buildup narrows the blood vessels, which blocks the healthy flow of blood in the body and can potentially cause a heart attack or other problems. For this reason, experts recommend consuming less than 300 milligrams of dietary cholesterol per day.
Cholesterol also travels within the central nervous system and is important for normal brain functioning. Too much of it, however, may have negative consequences for learning and memory. Reducing cholesterol through the use of drugs called statins may improve memory, but more research is needed in this regard.

What Should My Cholesterol Levels Be
Blood cholesterol is measured in units called millimoles per litre of blood, often shortened to mmol/L.
As a general guide, total cholesterol levels should be:
- 5mmol/L or less for healthy adults
- 4mmol/L or less for those at high risk
As a general guide, LDL levels should be:
- 3mmol/L or less for healthy adults
- 2mmol/L or less for those at high risk
An ideal level of HDL is above 1mmol/L. A lower level of HDL can increase your risk of heart disease.
Your ratio of total cholesterol to HDL may also be calculated. This is your total cholesterol level divided by your HDL level. Generally, this ratio should be below four, as a higher ratio increases your risk of heart disease.
Cholesterol is only one risk factor. The level at which specific treatment is required will depend on whether other risk factors, such as smoking and high blood pressure, are also present.
Foods That Contain No Cholesterol
Keeping a healthy balance of good and bad cholesterol is especially important for good heart health. A healthy diet can help lower your cravings for foods with high amounts of cholesterol, and lower your bad cholesterol, and maintain good cholesterol, plus help to lower your risk of stroke and heart attack. If you are currently eating plenty of these foods, then keep it up. If you are not, start by adding them to your diet now.
1. Rice and Grains
For a cholesterol free diet, you can add rice and grains. A majority of starches, which includes beans, rice and bread, have little to no cholesterol. Ingredients added in their preparation, however, such as butter on bread or lard in refried beans, could contain fats which are animal based and high in cholesterol.
2. Potatoes
Potato is one of the cholesterol free foods. Like breads and beans though, be careful of how the potatoes are prepared. Most French fries are made in vegetable oil, which has a low cholesterol content, but it is high in fat. When you are trying to find cholesterol free foods, dont forget that the best to go for are baked potatoes.
3. Mushrooms
There are many different ways in which mushrooms can be prepared. They work great as a pizza topping, but be careful of the cheese since there is a lot of cholesterol there. You could also swap out the hamburger patty with some portabella mushroom caps. However, if you prepare them, mushrooms are a great choice for a cholesterol free food.
4. Fish
5. Garlic and Onions

Highest Cholesterol Foods List
According to the National Agricultural Laboratorys Nutrient Lists from Standard Reference Legacy , the following 20 foods contain the highest amount of cholesterol. Processed, multi-ingredient foods from the list have been deliberately excluded, while single ingredient foodstuffs have the attention.
Consider, however, that many of the foods on this list are the main ingredient in other food products, such as eggnog and queso, which typically contain 139-150 mg of cholesterol per cup respectively.
Description |
In general, the most common food sources of cholesterol included egg yolk, shrimp, beef, and pork, poultry, as well as cheese and butter. Butter contains 50 g of saturated fat and 214 mg of cholesterol per 100 g, while a 50g egg contains just 1.56 g of saturated fat and 186 mg of cholesterol. 2
If youre looking to keep your cholesterol intake in check, consider removing the foods listed above from your diet.
Notice that, with the notable exception of eggs, many of the foods high in cholesterol are also high in saturated fat, which instructs your liver to produce more cholesterol. Something of a double whammy for cholesterol? Maybe.
Common Misconceptions About Foods And Cholesterol
Just because a food contains cholesterol does not mean it will raise cholesterol levels. In fact, the latest Dietary Guidelines for Americans of 2015-2020 removed the recommendation to limit dietary cholesterol to 300 mg per day, stating that adequate evidence was not available. Extensive research does not show that eating foods that contain cholesterol causes heart disease.
However, many foods remain feared for the belief that they increase the risk for heart disease or harm overall health. Some of these foods are highlighted below:
In addition to these foods, there has been concern over the recently trending ketogenic diet and its role in cholesterol levels. This style of eating limits nearly all sources of carbohydrates and instead gets a majority of calories and other nutrients from high-fat foods and protein. This diet includes eating large amounts of meat, eggs, cheese, and other high cholesterol, high saturated fat foods.
While it may seem as though this style of eating would be harmful to cholesterol levels, current research does not support this so far.
