In modern football, where the margins between victory and defeat are increasingly narrow, mental performance has become a determining factor. The ability to make quick decisions, stay focused, and handle pressure depends largely on an often underestimated element: nutrition. Beyond physical or tactical training, what a player eats directly influences their mind, energy, and cognitive capacity on the field.
At SIA Academy, we understand that a complete footballer is not only shaped through ball work and gym sessions but also through an integral approach that includes balanced, planned, and adapted nutrition for every demand. For us, nourishment is not a complement but a fundamental pillar of overall performance.

The link between food and the brain
The brain is an organ that consumes a large portion of the body’s energy, and that energy comes directly from food. That is why poor nutrition can affect concentration, memory, and decision-making. Recent studies show that glucose levels and certain micronutrients such as iron, zinc, and B vitamins are closely linked to mental performance.
When a player eats properly, their brain works with greater clarity and speed. On the other hand, an unbalanced diet leads to mental fatigue, slower reactions, and mistakes in key moments of the match. At SIA Academy, we teach our footballers to understand this connection between mind and nutrition, so they realize that every meal is an opportunity to improve performance.
As Cristóbal, the academy’s nutritionist, explains:
“The mind is also trained at the table. A well-nourished player thinks faster, stays focused, and makes better decisions under pressure.”
Macronutrients: energy for mind and body
Macronutrients — carbohydrates, proteins, and fats — are the foundation of all sports nutrition, but their role goes beyond the physical. Carbohydrates, for example, are the brain’s main source of energy. If a player doesn’t consume enough, they may experience loss of focus and slower thinking.
At SIA Academy, we carefully plan every menu to ensure our players have a constant supply of brain glucose. We also emphasize healthy fats such as those found in avocado, oily fish, and nuts, which are essential for neural function and emotional stability.
Proteins also play a key role, as they are involved in the production of neurotransmitters such as dopamine and serotonin, which directly influence motivation and mood. A balanced nutrition in these macronutrients allows the player to maintain mental focus throughout the match.
Micronutrients: the small allies of concentration
If macronutrients provide energy, micronutrients keep the brain in balance. Minerals such as magnesium and iron, and vitamins like B12 and D, influence memory, concentration, and reaction time. At SIA Academy, we conduct regular evaluations to detect potential deficiencies and correct them through nutrition or, if necessary, controlled supplementation.
We also promote the consumption of natural foods rich in antioxidants — such as berries, spinach, and pure cocoa — which help combat oxidative stress caused by intense training demands. A well-nourished brain not only thinks better but also recovers faster from mental fatigue.
Hydration and stress control
It’s often forgotten that hydration is also part of proper nutrition. A 2% loss of body fluids can significantly reduce attention and coordination. That’s why at SIA Academy, we monitor our players’ hydration levels before, during, and after every training session or match.
We also promote nutrition habits that help regulate stress and anxiety. Foods rich in tryptophan, magnesium, or omega-3 fatty acids contribute to emotional stability — something essential for performing under pressure. As Cristóbal rightly says:
“A calm player thinks better. Good nutrition not only feeds the body, it also soothes the mind.”
Nutritional education: shaping conscious players
One of our main goals at SIA Academy is to help players understand why they eat what they eat. Nutritional education is part of our training program because we believe knowledge brings autonomy and responsibility. We teach them to read labels, plan their meals, and distinguish between functional nutrition and merely caloric eating.
In addition, we work with personalized plans based on field position, training load, and season timing. Preparing for a decisive match is not the same as recovering from an injury, and nutrition must adapt to each situation to support both physical and mental balance.
Nutrition as a competitive advantage
In professional football, where all players train with similar intensity, the small details make the difference. Proper nourishment can be that extra factor that keeps the mind sharp and energy stable until the 90th minute. At SIA Academy, we see it every day: those who eat properly not only perform better but also think faster, react quicker, and make smarter decisions on the pitch.
The connection between nourishment and mental performance is clear and powerful. It’s not just about eating well, but about eating with purpose. Feeding the mind means feeding the game. And in a sport where mental quickness defines success, nutrition becomes the footballer’s best ally.
