What is a 'Processed' Food, Anyway?
To understand where prosciutto stands, it's essential to grasp the nuances of food processing. The World Health Organization (WHO) and other food classification systems, like the NOVA system, define 'processed' food in different ways. At a basic level, processed food is any food that has been altered from its natural state for safety or convenience, including methods like freezing, canning, and salting.
- Minimally Processed (NOVA Group 1): This includes foods that have simply been washed, cut, or frozen, such as bagged spinach or frozen vegetables.
- Processed Culinary Ingredients (NOVA Group 2): Substances derived from Group 1 foods that are not typically eaten alone but are used for cooking, like olive oil, butter, and salt.
- Processed Foods (NOVA Group 3): Simple foods made by adding salt, sugar, or oil to Group 1 foods to enhance flavor or extend shelf life. Traditional cheeses, canned fish, and cured meats like authentic prosciutto fall into this category.
- Ultra-Processed Foods (NOVA Group 4): Industrial formulations with five or more ingredients, often including additives, colorings, and flavorings not typically found in a home kitchen. Examples include packaged snacks, breakfast cereals, and sodas.
Given these classifications, genuine, traditionally made prosciutto is a processed food (Group 3), not an ultra-processed one (Group 4).
The Traditional Prosciutto Process: A Study in Simplicity
The journey of a true Prosciutto di Parma or Prosciutto di San Daniele is a testament to minimal intervention, relying on centuries-old techniques. The process is elegant and simple, using only a few natural ingredients and a lot of patience.
The Curing Steps for Authentic Prosciutto
- Selection: High-quality pork legs are chosen from specially bred pigs raised under strict guidelines.
- Salting: An expert 'salt master' applies a minimal amount of sea salt to the ham by hand. This is the only preservative used for authentic PDO-certified hams.
- Resting: The hams are stored in temperature and humidity-controlled rooms for several weeks to allow the salt to be absorbed properly.
- Washing & Drying: The excess salt is washed off, and the hams are hung to dry for a few days.
- Initial Curing: The hams are moved to well-ventilated rooms with large windows to allow for natural airflow. This is a critical stage for developing the prosciutto's signature flavor.
- Greasing: The exposed meat is coated with a mixture of lard, salt, and pepper to prevent it from drying out too quickly.
- Final Aging: The hams are moved to darker, less airy cellars for the final maturation. The entire curing process, from salting to final aging, lasts a minimum of 14 months for Prosciutto di Parma.
Prosciutto vs. Other Cured Meats
Not all cured meats are created equal. The classification of 'processed' can cover a wide spectrum of preparation methods. The minimal ingredient list and lengthy, traditional aging process of authentic prosciutto stand in stark contrast to many industrial cured meat products.
Comparison Table: Traditional Prosciutto vs. Ultra-Processed Meat
| Feature | Traditional Prosciutto (e.g., di Parma) | Ultra-Processed Meat (e.g., some hot dogs, luncheon meats) |
|---|---|---|
| Key Ingredients | Pork, Sea Salt, Air, Time | Mechanically separated meat, fillers, high sodium, sugar, and multiple synthetic additives |
| Preservatives | Only salt | Nitrites, nitrates, chemical flavorings, and other preservatives |
| Processing Method | Hand-cured, natural aging for months or years | Industrial, high-speed production, often involving emulsification and rapid cooking |
| Nutritional Density | High in protein, B vitamins, and healthy fats like oleic acid | Often low in nutritional value, high in saturated fat and sodium |
| Flavor Profile | Complex, savory, and delicate from natural aging | Artificially enhanced and often uniform taste profile |
Health Considerations: Sodium and Nitrites
While authentic prosciutto is a simpler product than many processed meats, there are still health aspects to consider. It is high in sodium due to the curing process. Excessive sodium intake is linked to increased blood pressure and heart disease risk. While authentic Prosciutto di Parma does not contain added nitrates or nitrites, other non-DOP prosciuttos might. The WHO classifies all processed meat as a carcinogen due to potential links with colorectal cancer, though the mechanisms for this link are complex and heavily debated, particularly concerning nitrites. Moderation is key for enjoying prosciutto within a balanced diet.
Conclusion: A Matter of Definition and Quality
So, is prosciutto a highly processed food? Technically, yes, it is a processed food, but the term itself doesn't tell the whole story. Authentic, traditionally-cured prosciutto is a processed meat that uses minimal, natural ingredients and time-honored methods. It is far from the definition of an ultra-processed food, which relies on a long list of artificial additives and extensive industrial modification. Consumers should be aware of the difference, check labels for additives like nitrates, and consume it in moderation as part of a healthy lifestyle.

Lists of Key Takeaways
- Understanding Processing: Prosciutto is a cured food, classifying it as processed, but not ultra-processed based on systems like NOVA.
- Traditional Methods: Authentic prosciutto uses minimal ingredients—pork, sea salt, air, and time—without the synthetic additives found in ultra-processed products.
- Minimal Ingredients: For DOP-certified prosciutto, salt is the only preservative, avoiding the nitrates and nitrites common in other cured meats.
- Health Factors: Prosciutto is high in sodium, so moderation is important, especially for those managing blood pressure.
- Quality Matters: The level of processing can vary depending on the product; always check the label to identify if it contains numerous additives.
FAQs
Q: What is the difference between prosciutto and ultra-processed meat? A: Prosciutto is traditionally made with just a few natural ingredients like pork and salt over a long curing period, while ultra-processed meat involves extensive industrial processes and multiple synthetic additives not found in home cooking.
Q: Is Prosciutto di Parma processed? A: Yes, Prosciutto di Parma is a processed food because it is cured with sea salt. However, it is not ultra-processed and contains no chemical preservatives.
Q: Does all prosciutto contain nitrates or nitrites? A: No, authentic prosciutto with a PDO (Protected Designation of Origin) certification, such as Prosciutto di Parma, prohibits the use of nitrates and nitrites. Other, non-traditional versions may contain them.
Q: Why is prosciutto so high in sodium? A: The high sodium content in prosciutto is a direct result of the curing process, where salt is used as the primary agent for preservation.
Q: Can I eat prosciutto every day? A: Due to its high sodium content, it is best to consume prosciutto in moderation as part of a balanced diet.
Q: Is prosciutto better for you than hot dogs? A: Authentic prosciutto is generally considered a higher-quality, less-processed product than most industrial hot dogs, which are typically classified as ultra-processed.
Q: Does curing make a food unhealthy? A: While curing is a form of processing, it doesn't automatically make a food unhealthy. The health implications depend on the specific ingredients, additives, and overall dietary context, with moderation being key.
