Debunking myths: Iberian pork consumption, cholesterol, and liver health

In the world of Iberian products, few things arouse as much emotion as the gesture of cutting a thin slice of ham and watching the marbled fat slowly begin to melt upon contact with room temperature. It is a spectacle for the senses, an unmistakable aroma that transports us to the pastures of Salamanca, and a delight for the palate. However, for years a recurring question has existed: is Iberian ham truly healthy, or should we consume it with caution due to its fat content?

There is a popular belief that any animal fat harms our cardiovascular health or saturates our liver. But when we talk about high-quality Iberian products, especially those from free-range pigs fed with acorns, scientific evidence reveals a very different reality.

Iberian Fat: Why Iberian Pork is the "Olive Tree with Legs"

To understand the impact of Iberian pork on our health, we must first look at its origin in the "dehesa" (pastureland). During the "montanera" season, the acorns from holm oaks and cork oaks provide the animal with extraordinary nutritional richness.

The lipid profile of acorn-fed Iberian pork is composed of more than 50% to 55% oleic acid, the same monounsaturated fatty acid that characterizes extra virgin olive oil. For this reason, in the agri-food and nutrition sector, Iberian pork is affectionately known as the 'olive tree with legs'.

Unlike saturated fats or trans fats from ultra-processed industries, monounsaturated fatty acids exert a direct cardioprotective function in the body:

  • They raise "good" cholesterol (HDL): They help transport cholesterol from the arteries back to the liver for subsequent elimination.
  • They reduce "bad" cholesterol (LDL): They prevent the formation of atheromatous plaque, responsible for hardening of the arteries.

What Science Says: Evidence of Cardiovascular Health

It's not just about tradition or intuition; the relationship between Iberian ham consumption and vascular health has been corroborated in top-level clinical research. Here are some examples:

The Study from Ramón y Cajal University Hospital

Researchers from the Endothelium and Cardiometabolic Medicine Unit of Ramón y Cajal University Hospital in Madrid, led by Dr. José Sabán, conducted a pioneering study on the effects of Iberian ham on endothelial function (the inner layer that lines blood vessels).

The results showed that moderate and continued consumption of Iberian ham (about 50 grams a day for six weeks) significantly improves blood circulation and vascular health. Furthermore, the research demonstrated the existence of 'endothelial memory': the vascular benefits were maintained weeks after the intake period ended.

Trial from Juan Ramón Jiménez Hospital and Primary Care

A clinical study led by Dr. Emilio Márquez Contreras (from Juan Ramón Jiménez Hospital and the Huelva-Costa Health District) analyzed the effect of including 40 grams daily of 100% Iberian acorn-fed ham in the usual diet of a group of adults.

The trial confirmed a notable increase in "good" cholesterol (HDL) concentration and a significant decrease in triglycerides and "bad" cholesterol (LDL). Likewise, a reduction in blood uric acid levels was observed, and it was confirmed that a controlled daily portion did not increase participants' body weight or blood pressure.

Iberian Ham and Liver Health: Antioxidants and Digestibility

At the hepatic level, the usual fear lies in the accumulation of fat or oxidative stress in the liver. However, monounsaturated fat does not act in the same way as heavy saturated fats.

Antioxidant protection: During the "montanera" (acorn-feeding season), acorns transmit nutrients such as tocopherols (vitamin E) and polyphenols to the pig's adipose tissue. These compounds are powerful natural antioxidants that reduce cellular oxidative stress and help protect the liver's metabolic function.

High-quality proteins and bioactive peptides: Research carried out in universities, such as studies on oxidation markers at the University of Salamanca, has highlighted that the slow and natural curing process in cellars breaks down proteins into smaller, easily digestible peptides. These essential nutrients nourish the body without overloading the digestive system or liver function.

The Transparency That Defines Us: Balance and Common Sense

At Ibéricos Torreón, we like to call things by their name and communicate with honesty. Quality Iberian ham is an extraordinary food within the Mediterranean Diet, but like all great gastronomic products, it should be consumed with common sense:

Attention to salt: The curing of ham requires the use of sea salt for its natural preservation. Although artisanal processes seek the right point of seasoning, people on strict diets with severe sodium restriction must adapt their intake.

Caloric density: This is a product with high energy value (around 250–300 kcal per 100 grams). Incorporating between 30 and 50 grams per day as part of an active lifestyle and a varied diet is the ideal measure to enjoy its properties without consuming excessive calories.

Not all cured meats are equal: The key to these benefits lies in the pure breed, free-range rearing, natural feeding, and slow curing in drying sheds. Industrial ultra-processed meat derivatives do not share the nutritional structure of good ham or Iberian loin.

Taking care of your health and indulging in the pleasure of good food are not opposing paths. When we sit down to enjoy a serving of Iberian ham made with patience in our facilities in Villares de la Reina, we are savoring the fruit of the land of Salamanca, respect for time, and a nutritional heritage that nourishes us from within as much as it comforts us from without.
