My research explores how functional foods could help reduce inflammation and oxidative stress—unlocking healthier aging for all.

Functional food 

Who wouldn’t want to be healthier? What if the food we eat every day could help us become healthier, little by little? We often hear about which types of food are good for health, but there is much more to consider than just food types.

How the food is prepared, and what it is eaten with, can drastically change the levels of active compounds even before consumption.

Consumption methods and food companions matter

Many bioactive compounds are sensitive to heat or oxidation. Cooking methods that involve high temperatures can accelerate the degradation of these compounds, reducing their beneficial potential. Meanwhile, certain food combinations can enhance the absorption of bioactive compounds, while others may have the opposite effects. My goal is to identify the best preparation methods and food pairings to maximize the health benefits we obtain from food.

Functional food for chronic low-grade inflammation

Patients with age-related conditions such as coronary artery disease often experience chronic low-grade chronic inflammation and elevated oxidative stress, even when they adhere to their prescribed medications. These conditions can further increase the risk of heart attack and stroke, yet there are currently no medical treatments that directly target them.

This is where functional foods can play a vital role. They are accessible, safe, and can complement existing medical therapies. My current research aims to develop dietary strategies using functional foods with anti-inflammatory and antioxidant properties to help reduce inflammation and oxidative stress in the aging population.

Inflammaging in cardiometabolic diseases

A growing body of evidence shows that dysfunction of the immune system plays a role in the aging process and the development of age-related cardiovascular or metabolic diseases. My research focuses on the changes in immune composition and the dysfunction of innate immune cells such as neutrophils and monocytes.
