Longevity: the 5 foods to limit according to Dr Valter Longo if you hope to become a centenarian

Reaching 100 years of age is a dream goal. However, some of the foods we eat most often could put the brakes on this ambition. Dr. Valter Longo, an Italian longevity specialist, has drawn up a list of what we need to limit if we hope to blow out the candles of a centenarian.

Italian researcher and blue zone expert

Dr Valter Longo has been studying longevity in Italy for almost 20 years. He grew up in Calabria, in the small municipality of Molochio. He currently heads the Longevity and Cancer Laboratory at the IFOM Institute of Molecular Oncology in Milan.

In his opinion, Italy is the ideal location for his work. The country is home to several regions where people live longer. Sardinia was one of the first regions designated as a blue zone by researcher Dan Buettner.

As a reminder, the blue zones are the regions of the world with the highest number of fit, centenarian inhabitants. And one of the main lessons to be learned from these regions is the importance ofnutrition.

“I think these are very good ingredients. It just so happens, however, that they are problematic.”

Valter Longo’s longevity diet

In an interview with CNBC Make it, Dr. Longo recommends adopting the so-called longevity diet. This diet is inspired by the Okinawa and Mediterranean diets. It is based on a predominantly vegan diet, with a high vegetable intake.

Pulses, nuts, seeds and whole grains take center stage. In addition, the researcher recommends going fishing 3 to 4 times a week for those who can. This approach favors marine rather than terrestrial proteins.

• A mainly vegan diet
• Relatively low fruit consumption
• Plenty of legumes
• Nuts and seeds
• Wholegrain cereals

Foods to limit according to Dr Longo

The scientist recommends avoiding red and white meat. He also recommends a maximum of 3 eggs a week. Very little cheese and very few animal products complete these restrictions.

As for foods to limit, Valter Longo cites five that are problematic. And yet, these products feature in most French kitchens. Potatoes, pizza, protein, bread and pasta are all on the list.

The researcher points out that these foods are not bad in themselves. On the other hand, their excessive consumption poses a real threat to longevity. People eat too many of them every day.

Why these foods accelerate aging

Dr. Longo explains the problem simply. These foods convert to sugar very quickly once digested. Their conversion is almost as fast as that of table sugar.

This rapid transformation places heavy demands on the body. As a result, excessive consumption of these products could slow down your chances of reaching 100. The body undergoes a repeated glycemic peak that wears it down prematurely.

How to adapt your daily diet

Reducing these foods does not mean eliminating them altogether. The researcher speaks of moderation rather than prohibition. From now on, everyone can adjust their portions to preserve their health over the long term.

Replace some starchy foods with vegetables to add variety to your plate. Pulses offer a satiating alternative to pasta or white bread. This approach is compatible with an active lifestyle.

In 2026, these recommendations will inform our dietary choices. Dr. Valter Longo provides concrete guidelines for healthy aging. His work on blue zones continues to inspire those who wish to live longer.
