In modern football, sports nutrition is a key pillar of performance. It’s no longer about counting calories or following generic diets. It’s about bringing science to the player’s daily life. Every meal adapts to context, workload, and physical needs.
In a new episode of FSI Talk, Alfredo Santalla, Professor of Exercise Physiology at the University Pablo de Olavide, speaks with Cristian Petri, nutritionist at ACF Fiorentina and Chief Nutritional Officer of the Italian Rugby Federation. Together, they explore how science and cooking combine in Serie A to improve football performance.
From Paper to Plate: Science, Empathy and Cooking
For Cristian Petri, the challenge in football nutrition is not knowing science. It’s turning it into food that players actually enjoy.
“I have the mind, the chef has the hand,”
The collaboration between nutritionist and chef is essential. It makes menus both effective and appealing. The key is empathy with players, nutrition education, and creativity — not rigid rules.
Personalized Menus for Players
Creating a personalized menu for footballers means balancing performance, digestion, and motivation. At clubs like Fiorentina, nutrition plans change based on position, training load, travel, or match frequency.
“It’s not about eating the same every day. Variety means health and motivation.”
The goal is to keep players engaged. Avoiding monotony improves long-term adherence and performance.
Post-Match Recovery: Energy Before Perfection
Post-match recovery is one of the most critical moments. Petri insists that energy comes first.
“Sometimes it’s not about eating clean — it’s about eating energy.”
After every game, the body needs to restore glycogen, rehydrate, and rebalance hormones. Fiorentina players start recovery with shakes in the locker room, followed by solid meals and snacks high in carbs and protein.
During travel, the staff prepares healthy snack bags — protein bars, yogurts, or legume chips. This ensures players keep proper nutrition even on the move.
Sports Supplementation: From Duty to Pleasure
Petri’s sports supplementation approach mixes science, creativity, and adherence. His rule is simple: make it desirable.
“If after three times you say you can’t take more protein, next time I’ll give you chocolate ice cream with protein. For you, it’s ice cream, not protein.”
This mindset turns nutrition into motivation. Protein ice cream, natural shakes, or alcohol-free ‘gin tonics’ with creatine make routines enjoyable and sustainable across a 60-match season.
Applied Science: Probiotics, Inflammation and Biomarkers
Elite sports nutrition also depends on ongoing monitoring. Fiorentina players are tested for gut microbiota, cortisol, and testosterone. These data help personalize supplements and prevent inflammation.
“If a player hasn’t recovered properly, we continue with targeted supplementation.”
Nutrition, physiology, and sports medicine now work together to speed up recovery and keep players available all season.
Working in Football as a Nutritionist
Cristian Petri ends with a clear message:
“Forcing doesn’t teach anything. Educating change — that’s success in my job.”
A football nutritionist does much more than calculate macros. The role involves understanding the player, their mindset, and their relationship with food. Educate, motivate, and adapt — these are the pillars of effective sports nutrition in high performance.
