Bacon grease is rendered pork fat, and it is high in saturated fat and cholesterol. That makes it a food to limit if you have heart disease, high LDL cholesterol, or a history of stroke. For most healthy people, the bigger issue is how much of it you eat and how often — not whether a spoonful will harm you.
Bacon grease has been used in Southern and Appalachian cooking for generations. It is also having a moment online, with people drinking it, cooking everything in it, and calling it a health food. That last part is not supported by evidence. Bacon grease is not a health food. It is also not poison. It sits somewhere in the middle, and where it lands for you depends on your health and your overall diet.
What Is Bacon Grease, Exactly?
Bacon grease is the fat that renders out of pork belly when you cook bacon. It is mostly fat, with small amounts of protein and water. Once cooled, it turns into a soft white or pale yellow solid.
Nutritionally, it is close to other animal fats like lard, tallow, and butter. A tablespoon of bacon grease contains roughly 110 to 120 calories and about 12 to 13 grams of fat. Most of that fat is saturated and monounsaturated, with a smaller amount of polyunsaturated fat. It also contains cholesterol, since it comes from an animal source.
One detail people often miss: bacon grease carries some of the flavor and salt of the bacon it came from. That matters if you are watching your sodium. The fat itself is not high in sodium, but bits of bacon and curing salts can end up in the jar.
Is Bacon Grease Bad for Your Heart?
Saturated fat raises LDL cholesterol in most people, and LDL cholesterol is a well-established driver of heart disease risk. This is one of the more solid findings in nutrition science. The effect is real, but it is also dose-dependent.
Bacon grease is roughly one-third saturated fat by weight. That is lower than butter or tallow, but higher than most vegetable oils. If you swap the fat you normally cook with for bacon grease and eat more total saturated fat as a result, your LDL cholesterol will likely go up over time.
The American Heart Association and other major health organizations continue to recommend limiting saturated fat. The general guidance is to keep saturated fat to a small share of daily calories and replace some of it with unsaturated fats from sources like olive oil, nuts, and fish. That direction has been consistent for decades.
What the evidence does not support is the idea that bacon grease is somehow protective for the heart. No large human trial has shown that. Claims that it is “heart-healthy” because it contains some monounsaturated fat ignore the saturated fat and cholesterol it also contains.
Does Bacon Grease Cause Cancer?
Bacon grease itself has not been shown to cause cancer. The concern is about processed meats, not the rendered fat specifically.
Bacon is a processed meat. The World Health Organization’s cancer agency classifies processed meats as carcinogenic to humans, based on strong evidence linking them to colorectal cancer. That classification applies to the meat, not to the fat you cook out of it. How much this matters for bacon grease alone is not well studied.
What is clear: if you eat a lot of bacon, the meat is the bigger concern than the grease. Cooking bacon at high heat also produces compounds that some research has linked to health risks, though the evidence on how much this matters in a normal diet is limited.
Is Bacon Grease Healthier Than Butter or Olive Oil?
No. Bacon grease is not healthier than olive oil, and it is roughly comparable to butter. Both bacon grease and butter are high in saturated fat. Olive oil is mostly monounsaturated fat and has a better track record for heart health.
Here is a rough comparison of one tablespoon of each:
| Fat | Calories | Saturated fat (approx.) | Main fat type |
|---|---|---|---|
| Bacon grease | ~115 | ~4–5 g | Saturated + monounsaturated |
| Butter | ~100 | ~7 g | Saturated |
| Olive oil | ~120 | ~2 g | Monounsaturated |
| Lard | ~115 | ~5 g | Saturated + monounsaturated |
These are approximate values and vary by brand and how the fat was rendered. The takeaway is that bacon grease is not a low-saturated-fat choice. If heart health is your goal, olive oil and other plant oils are the better everyday option.
Can You Eat Bacon Grease Every Day?
You can eat it daily without immediate harm if you are otherwise healthy and your overall diet is balanced. But “can” is not the same as “should.”
Daily use adds up. A few tablespoons a day is a meaningful amount of saturated fat and calories. Over months and years, that can push LDL cholesterol up and add excess calories that contribute to weight gain.
Some people are more sensitive to dietary saturated fat than others. Genetics affect how much your cholesterol responds to what you eat. If you already have high LDL cholesterol, diabetes, or heart disease, the case for limiting bacon grease is stronger.
If you enjoy the flavor, using it occasionally as a seasoning rather than as your main cooking fat is a reasonable middle ground. A little goes a long way for taste.
What About the Viral Claims?
Social media has pushed several claims about bacon grease that do not hold up. Here are the common ones and where they actually stand.
- “It is a superfood.” No. It is a fat with no vitamins, minerals, or fiber worth noting. It provides calories and flavor, not nutrients.
- “It is healthier than seed oils.” Not supported. The evidence linking seed oils to harm is weak and largely based on animal and mechanistic studies, not human outcomes.
- “It has no cholesterol impact.” False. Bacon grease contains saturated fat and cholesterol, both of which can affect blood cholesterol in some people.
- “Drinking it boosts energy.” It provides calories, which are energy, but there is nothing special about bacon grease for energy. Any fat does the same.
The pattern here is familiar. A traditional food gets rebranded as a health secret because it is old, natural, or nostalgic. Being traditional and natural does not make something healthy in large amounts. It also does not make it dangerous in small amounts.
How Should You Store and Use It Safely?
Bacon grease can be saved and reused, but food safety matters. Let it cool, strain out the solids, and store it in a covered container in the refrigerator. It keeps for several weeks refrigerated and longer in the freezer.
Reusing cooking fat repeatedly at high heat can cause it to break down and form compounds you would rather not eat. If the grease smells off, looks cloudy in a way it did not before, or has changed color, throw it out. Do not keep reusing the same batch indefinitely.
Bacon grease left at room temperature for long periods can go rancid. Rancid fat tastes bad and is not something you want to cook with. When in doubt, toss it.
The Bottom Line
Bacon grease is not bad for you in small amounts, and it is not good for you in large amounts. It is a high-saturated-fat, high-calorie animal fat, similar to butter and lard. The evidence does not support the viral claims that it is a health food.
If you have heart disease, high LDL cholesterol, or diabetes, limiting it makes sense. If you are healthy and enjoy it, using it now and then as a flavoring is unlikely to cause harm. The rest of your diet and your overall saturated fat intake matter more than any single ingredient.
Frequently Asked Questions
Is bacon grease bad for you?
It is not harmful in small amounts, but it is high in saturated fat and calories. Eating a lot of it regularly can raise LDL cholesterol and add excess calories.
Is bacon grease healthier than butter?
No, they are roughly comparable in saturated fat. Olive oil and other plant oils are the better everyday choice for heart health.
Can you drink bacon grease?
You can, but there is no health benefit and it adds a large amount of saturated fat and calories quickly. No evidence supports drinking it for any health reason.
Does bacon grease go bad?
Yes, it can go rancid if left at room temperature too long. Store it covered in the refrigerator and discard it if it smells off or changes color.
