Salami is a traditionally fermented cured meat hailing from Italy. There are several different varieties of salami (such as pepperoni and ‘nduja), and each has its own unique characteristics and nutritional profile.
Public health guidance considers high intake of processed meat like salami a health concern for several reasons. Evidence from observational research, for example, finds strong and consistent associations between processed meat intake and a higher risk of specific cancers.
The high sodium content of processed meats and their use of preservatives like sodium nitrate and nitrite may contribute to these associations, and they are all ingredients in salami. However, salami is traditionally consumed in small portions, and it provides notable amounts of protein, B vitamins, selenium, and zinc.
This article provides an objective guide to salami, its nutrients, and its potential health effects, looking at both sides of the story.

What is Salami?
Salami is a kind of fermented sausage made by curing meat.
In the image above, you can see a salami sausage next to several slices of salami on a chopping board. If you look closely, you’ll see that salami has lots of white fatty areas, which is due to its high fat content.
Traditional salami is not cooked like typical meat products, and its production process looks like this:
- Mixing: First, raw salami is made by mixing meat with seasoning, which can depend on the recipe. Ingredients like pepper and herbs are common, and the meat is typically pork but may also contain beef. A lactic acid bacterial culture may also be added to help ferment the meat.
- Preservation: At this stage, salt and additional preservatives like sodium nitrate and nitrite are added. These ingredients have a dual purpose, helping to flavor the meat as well as help prevent spoilage and bacterial growth.
- Fermentation and drying: Once the mixture has been put into sausage casings, it is hung to ferment in a temperature-controlled room, and this duration may vary depending on the producer and their recipe. After fermentation, the salami goes through a drying process to reduce moisture and enhance its shelf life.
What Ingredients Does Salami Contain?
As mentioned earlier, the exact ingredients in salami will depend on the variety and regional recipes. However, you will typically find some of the ingredients below in a salami product:
- Pork
- Pork fat
- Beef
- Salt
- Lactic acid starter culture
- Dextrose or other sugars
- Sodium nitrate
- Sodium nitrite
- Paprika
- Pepper
- Garlic
- Wine
- Fennel
- Citric acid
There are Many Types of Salami
You may be curious about how foods like salami, pepperoni, and chorizo differ.
In short, pepperoni is one of many types of salami, and there are dozens of different varieties. While this article focuses on Italian-style pork salami, there are several distinct cured sausages that fall under the broader ‘salami’ category.
Some of the most famous of these include:
- Pepperoni: An American cured meat product made from beef, pork, and paprika.
- ‘Nduja: An Italian spreadable cured sausage with a slightly spicy flavor.
When you buy salami, the packaging should clearly label which kind it is.
Is Salami a Good Source of Nutrients?
Since the primary ingredient in salami is pork, it provides high amounts of several vitamins and minerals per 100 grams.
That said, the issue here is that most people do not consume salami in 100-gram portions. This is partly due to its overall nutritional composition; since meat is mixed with fat to make salami, it contains high levels of fat, saturated fat, and overall calories.
Similar to other fermented meats like prosciutto, salami is also very high in sodium. For these reasons, the typical serving suggestion for salami is one ounce, which limits the amount of vitamins and minerals present.
A one ounce (28.35g) serving of salami typically provides the following nutrients:
- Calories: 119 kcal
- Carbohydrates: 0.37g
- Sugars: 0.37g
- Fat: 10.4g
- Saturated fat: 3.67g
- Vitamin B12: 33% of the Daily Value (% DV)
- Sodium: 23% DV
- Thiamin (B1): 22% DV
- Selenium: 13% DV
- Zinc: 11% DV
- Niacin (B3): 10% DV
- Vitamin B6: 9% DV
- Riboflavin (B2): 7% DV
- Pantothenic acid (B5): 6% DV
- Phosphorus: 5% DV
- Copper: 5% DV
As you can see, even a small one-ounce serving of salami provides notable amounts of several vitamins and minerals. This includes high amounts (≥20% DV) of vitamin B12, thiamin, and sodium.
Salami is High in Saturated Fat and Sodium
You may have noticed in the above nutrient list that an ounce serving of salami contains 3.67 grams of saturated fat and 23% of the Daily Value for sodium.
On a per-100-gram basis, salami typically contains:
- Saturated fat: 13.1g (65% DV)
- Sodium: 1890 mg (82% DV)
If you were to eat a larger amount of salami, it would be very easy to over-consume these nutrients.
Research has consistently shown that high intakes of saturated fat, can raise LDL cholesterol (LDL-C), sometimes known as “bad cholesterol.”
Equally, a 2024 systematic review demonstrated that higher dietary intakes of sodium were associated with higher blood pressure.
Both LDL-C and high blood pressure are recognized as causal risk factors for cardiovascular disease. For these reasons, it is important to consider the amount of saturated fat and sodium in salami and how it relates to your overall diet.
Why the Overall Diet Matters
As with anything in nutrition, we should always consider the part a food plays in the overall diet, as it’s the overall dietary pattern that impacts our health rather than one food at one time.
For diets that are already low in saturated fat and sodium, an occasional serving of salami is unlikely to be problematic. However, adding salami to diets that already provide more than the recommended levels of these nutrients would be different in terms of health risks.
Note: Individuals with high cholesterol or high blood pressure should exercise more caution and discuss with their healthcare provider. As salami is very high in sodium, this is particularly important for individuals with salt-sensitivity hypertension.
Processed Meats and Colorectal Cancer Risk
Salami is a processed meat, and processed meats have been linked to a greater risk of colorectal cancer. Preservatives like sodium nitrite (or nitrate) and high levels of salt have all been linked to colorectal cancer risk, and their inclusion in processed meat may contribute to these associations.
A recent 2026 systematic review found that processed meat intake was associated with a 65% increased risk of colorectal polyps. Polyps are clumps of additional cells, which can sometimes become cancerous over time.
Additionally, a 2026 systematic review found strong associations between processed meat intake and a higher risk of colorectal and gastric cancer.
Such findings have been consistent in scientific research, which previously led to the International Agency for Research on Cancer (IARC) classifying processed meat as carcinogenic to humans (group 1). This designation means that there is sufficient evidence from observational studies that processed meat can cause colorectal cancer.
While ‘group 1’ is the same group as tobacco and asbestos, the World Health Organization (WHO) made a point to note that processed meat doesn’t convey the same magnitude of risk.
In fact, the WHO later quantified that the available evidence IARC used to make their decision showed that every daily 50-gram serving of processed meat increased colorectal cancer risk by 18%. To know precisely what this means, we need to understand relative risk.
Understanding Relative Risk
It is important that you understand relative risk when seeing the risk estimates mentioned above, as they don’t mean individuals have an 18% increased risk in absolute terms. For example, the Cancer Research Institute notes that the lifetime risk of colorectal cancer is 1 in 25 for men and 1 in 26 for women; an approximate lifetime risk of 4%.
Now, if consuming 50g of processed meat daily increases the risk by 18%, this means an individual’s baseline lifetime risk may increase by 18% of 4% (0.72%); the lifetime risk would then stand at 4.72% rather than 4%.
To put these numbers into perspective, the Centers for Disease Control (CDC) state that smoking increases the lifetime risk of lung cancer by 15-30 times, which could be up to a 2900% increase in risk.
The absolute risk from processed meat for an individual is small, and it is mostly based on observational research, which shows an association (rather than establishing causation). However, it is a consistent finding which has led to public health guidelines on limiting processed meat intake.
Should You Eat Salami?
Salami is a food that many people enjoy, whether that’s as an occasional dietary choice or as part of a traditional diet. It is also nutrient-rich, providing a range of vitamins and minerals in notable amounts.
However, current research does indicate that high salami intakes may raise health risks. This is based on consistent associations between processed meat and colorectal cancer, and salami’s high sodium and saturated fat levels.
If you personally enjoy salami and want to include it in your diet, small occasional servings can be compatible with an overall healthy dietary pattern. However, total processed meat intake and the quality of the overall diet are key determinants in this.
