Lallemand's petfood expert Francesca Susca, DVM, Ph.D., was invited to give a lecture at the 5th Nordic Pet Food Conference in Porto, Portugal, an event dedicated to pet nutrition, health and well-being. She focused on the complex phenomenon of oxidative stress, an issue that concerns humans and pets alike.
Dr Susca also discussed the specificity and benefits of primary and secondary dietary antioxidants for applications in petfood, highlighting the synergy between complementary solutions.
What is oxidative stress?
During physiologic metabolic processes, the body's cells produce free radicals as well as antioxidant molecules to maintain the oxidative homeostasis. However, an imbalance between pro-oxidant and antioxidant molecules can occur either because of an increased production of free radicals or because of decreased antioxidant availability. The result is oxidative stress.
Oxidative stress has been recognised to be involved in many inflammatory, degenerative and neoplastic disorders, both in humans and pets. These include, among others, heart disease, cerebrovascular events, obesity, urinary tract disorders or kidney diseases. Furthermore, non-pathological conditions, which lead to an increased production of pro-oxidant molecules, are frequent and include intense physical activity or aging process.
Antioxidants: combination is the key
Oxidative stress starts with the formation of reactive oxygen species (°O2-, H2O2 or OH°), which can react with cell components (DNA, proteins or lipids), to generate secondary free radicals (ROO°).
