Bacon: Nutrition, Is Bacon Healthy, Turkey Bacon vs Pork Bacon

Bacon is pork belly that has been salted, usually smoked, and sliced, and it is one of the most common processed meats in American kitchens. A pan-fried slice has about 54 calories in USDA data, with nearly 4 grams of protein, 4 grams of fat and close to a tenth of the Daily Value for sodium. Is bacon healthy? The honest answer is that it is a salty, processed food that the World Health Organization’s cancer agency places in its highest evidence group for processed meat, so most guidance frames it as an occasional food rather than a staple. This guide covers bacon nutrition per slice, turkey bacon vs pork bacon, what “uncured” really means on a label, and safe storage.

What is bacon?

American bacon comes from the pork belly. The belly is soaked in or injected with a brine of salt, sugar and curing agents, often smoked, then sliced. Federal rules shape the product: a curing ingredient has to appear in the ingredient list, and the finished bellies sold as bacon may not weigh more than the fresh bellies did, so water cannot be used to bulk them up. Other styles you will see:

• Canadian bacon: made from the lean pork loin, not the belly, so it is far leaner. In USDA data a pan-fried slice has about 20 calories and less than half a gram of fat.
• Turkey bacon: chopped and formed turkey that is seasoned, smoked and sliced to look like strips. It is still a salted, processed product.
• Reduced-sodium bacon: made with less salt; USDA data show about half the sodium of regular cooked bacon per 100 grams.
• Meatless bacon: plant-based strips. They have no cholesterol but are still salty.

Bacon nutrition per slice

Values below come from the USDA FoodData Central SR Legacy database, per one cooked slice using USDA’s own slice weights. Slice sizes vary by brand and cooking method, so read the Nutrition Facts label on your package for exact numbers.

Bacon also supplies selenium and niacin: a pan-fried slice has about a tenth of the Daily Value for selenium in USDA data, a mineral covered in our selenium guide. Most people do not eat one slice, though, and the sodium adds up fast with each extra strip. The fat that renders out is mostly fat with no protein; USDA lists a teaspoon of bacon grease at about 39 calories and 8% of the Daily Value for saturated fat, similar in character to the lard it resembles.

Is bacon healthy? What the agencies say

Three official sources frame the question.

• WHO cancer agency (IARC), 2015: a working group classified processed meat as carcinogenic to humans (Group 1), based on sufficient evidence that it causes colorectal cancer. WHO defines processed meat as meat transformed through salting, curing, fermentation, smoking or similar processes, which describes bacon. IARC estimated that each 50 gram portion of processed meat eaten daily increases colorectal cancer risk by 18%, and its spokesperson said the risk for an individual remains small but grows with the amount eaten. Group 1 describes how strong the evidence is, not how large the risk is.
• Dietary Guidelines 2025-2030: the guidelines advise eating meat with no or limited added sugars, refined starches or chemical additives, say highly processed foods that are high in sodium should be avoided, and keep saturated fat at no more than 10% of daily calories.
• FDA sodium labeling: the FDA Daily Value for sodium is 2,300 milligrams, and FDA describes 20% DV or more per serving as high. One slice is under that line, but three or four slices are not.

Put together, bacon is a flavorful food that works as an accent, not a main protein source. If protein is what you are after, our guides to protein-rich foods and protein at breakfast list leaner choices, and eggs are the usual partner on the plate. For sodium across the whole diet, see our low-sodium guide. Readers following an all-meat eating style can compare notes in our carnivore diet article.

Turkey bacon vs pork bacon

Turkey bacon is often picked as the lighter option, and per slice that holds up: in USDA data a microwaved turkey slice has about 30 calories and less than half the saturated fat of a pan-fried pork slice. The picture changes per 100 grams of cooked product.

So turkey bacon trades some saturated fat for more sodium and cholesterol by weight, and it is still a salted, smoked, processed product. Canadian bacon is the leanest of the group in USDA data. Whichever you choose, the sodium line on the label is the number that varies most between brands. Our cholesterol in foods guide explains how dietary cholesterol is viewed today.

Uncured bacon and nitrites: what the label means

Regular bacon is made with sodium nitrite, which fixes the pink color and the familiar flavor. Federal rules allow nitrite in bacon but not nitrate, and they list vitamin E compounds as permitted in pump-processed bacon “to inhibit nitrosamine formation”, which shows regulators watch that chemistry closely. Bacon labeled uncured is a labeling category, not a salt-free or nitrite-free food:

• The rule: under 9 CFR 317.17, bacon made without added nitrate or nitrite may carry the word “Uncured” before the name, must say “No Nitrate or Nitrite Added”, and must say it is not preserved and should be kept refrigerated below 40°F unless processed in specific ways.
• Celery powder: most uncured bacon is made with celery powder or celery juice, which are naturally rich in nitrate that becomes nitrite. Our celery juice guide covers celery’s nitrate.
• Possible change: in December 2020 the USDA Food Safety and Inspection Service said it intends to propose rules barring “Uncured” and “No Nitrate or Nitrite Added” claims on meats made with any nitrate source, including celery powder. As of October 2026 the regulation text had not changed.

Cooking and storing bacon safely

• Fridge and freezer: FoodSafety.gov lists bacon at 1 week in the refrigerator (40°F or below) and 1 month in the freezer; freezer times are for quality, since food kept at 0°F stays safe.
• Use-by dates: follow the package date and the “Keep Refrigerated” line, which uncured bacon must carry.
• Grease: let rendered fat cool and solidify, then put it in the trash; it can clog drains.
• Cooking method: USDA data show baked and microwaved slices end up lighter than pan-fried ones, partly because more fat drains away. Draining on paper towels has the same aim.
