Ultra-processed foods are industrially formulated products made from substances extracted from real food, chemically modified ingredients, and additives. They often contain artificial flavors, colors, emulsifiers, preservatives, and sweeteners.

​

These foods are engineered to be hyper-palatable—intensely appealing to our senses—and include packaged snacks, sodas, frozen meals, breakfast cereals, flavored yogurts, processed meats, and many "diet" or "low-fat" products.

​

Even when they resemble real food, UPFs are usually far removed from their original natural form.

​

​

❓ Why Should I Care?

 

UPFs are designed for convenience, but at the cost of your long-term health. Their taste, texture, and shelf life are engineered to maximize consumption—not nutrition.

​

These foods override your body’s natural hunger cues, often leading to overeating and poor nutrient intake. What seems like a harmless snack or quick meal may, over time, increase your risk for serious chronic health conditions, all while becoming a daily habit you don't question.

​

​

📊 The Science Is Clear

 

A large and growing body of scientific research has established strong links between UPF consumption and a range of negative health outcomes. Studies have associated high intake of ultra-processed foods with increased risk of:

​

• Obesity

• Type 2 diabetes

• Cardiovascular disease

• Certain cancers

• Dementia including Alzheimer's 

• Depression and anxiety

• Premature death

 

These risks remain significant even after accounting for factors like body weight, exercise, and total calorie intake—suggesting that UPFs carry inherent risks beyond just “empty calories.”

🌍 Trends in Mediterranean Countries

​

Traditionally, the Mediterranean diet—rich in vegetables, legumes, olive oil, and whole grains—has been a model for health. Yet now:

• Even in Italy, Spain, and Malta, UPFs

• National data show Spain, Italy, Malta, and Middle Eastern Mediterranean countries are are pushing aside traditional diets, causing rising obesity and chronic disease.

• This shift has strained public health systems with escalating diabetes, hypertension, cardiovascular disease, and certain cancers.

​

🧪 Recent Scientific Evidence (2024–2025)

​

• Southern Italy (2024, Nutrients): A study of adults with obesity found that high UPF intake correlated with significantly greater adiposity and a weaker Mediterranean diet pattern.

• Spain (2024, DRECE Cohort): A national study found that increased UPF consumption predicted a higher risk of all-cause mortality among Spanish adults.

• Mediterranean Cohort (2024): A ScienceDirect analysis linked high UPF intake in a Mediterranean population to increased all-cause mortality following a long-term follow-up.

• Italy – UPF + Mediterranean Diet (May 2025): A large Italian cohort study concluded that combining high adherence to the Mediterranean diet with low UPF consumption led to the best survival outcomes and lowest non-cancer mortality.

🥗 From Mediterranean to Natural: A Diet for Today’s World

For many years, I recommended the Mediterranean diet to my patients. It was one of the most effective, evidence-based strategies available—rich in vegetables, legumes, olive oil, and other real foods.

​

But times have changed.

​

The health benefits of the Mediterranean diet came not only from what it included, but from what it left out—especially ultra-processed foods. Unfortunately, even in countries like Italy and Spain, ultra-processed products now dominate the food landscape. Obesity and chronic disease are rising in regions once protected by tradition.

​

That’s why I developed the Natural Diet.

​

It honors the core of the Mediterranean way of eating but takes a critical step forward: it places the elimination of ultra-processed foods at its foundation. The Natural Diet is not a trend or a nostalgic return to the past—it's a science-backed, practical response to today’s food environment. It’s built for the world we live in now.
