On World Food Day, it’s worth remembering: eating is much more than just satisfying hunger. It’s the foundation of our energy, our health, and even the way we think and feel.
1. Eating well is an investment in years of life
Science increasingly shows that a balanced diet is one of the most effective ways to prevent disease and keep the body functioning longer.
Clinical trials and systematic reviews demonstrate that dietary patterns like the Mediterranean diet and DASH (Dietary Approaches to Stop Hypertension) reduce the risk of cardiovascular disease, type 2 diabetes, and chronic inflammation—factors directly linked to healthy aging.
Following a balanced diet with fresh, whole, minimally processed foods is associated with more years of healthy life and a lower risk of chronic diseases.
The PREDIMED study (New England Journal of Medicine, 2018) and the Lyon Diet Heart Study showed that a diet rich in fruits, vegetables, legumes, whole grains, olive oil, and fatty fish can improve metabolic markers and reduce cardiovascular events, even in people at high risk.
The impact on the body is direct: food affects mechanisms that control cellular aging, such as inflammation, oxidative stress, and the IGF-1 hormonal axis, which regulates growth and regeneration.
In other words, what we eat influences the speed at which we age, both inside and out.
There is no single perfect diet. What truly matters is prioritizing real, varied foods, reducing ultra-processed products, and maintaining daily balance.
There are no magic formulas… only consistency. And it’s that consistency that sustains energy, immunity, and quality of life over the years.
2. What we eat affects the brain
Nutrition doesn’t just act on the visible body. It directly influences the brain, the gut, and the communication between them—the so-called gut-brain axis.
A diet rich in fiber, polyphenols, and bioactive compounds found in fruits, vegetables, legumes, and whole grains strengthens the gut microbiome, the community of bacteria that inhabit our intestines and regulate much of our health. This, in turn, improves mood, focus, and stress management.
On the other hand, excessive sugar and ultra-processed foods do the opposite: they increase inflammation and impair concentration.
Investing in balanced nutrition early in life is an investment in mental clarity, emotional stability, and healthy aging.

3. Nutrition is performance
The body needs the right fuel to function at its best, whether during training, at work, or in daily life.
Good dietary choices boost energy, speed up recovery, and reduce fatigue.
After exertion, high-quality proteins and anti-inflammatory foods help the body regenerate and adapt better, enabling consistent progress.
Science is clear: those who eat well recover better and perform better.
But it’s not just what you eat—the timing of meals also matters. Nutrition before, during, and after exercise directly influences protein synthesis, recovery, and adaptation to effort.
My perspective, supported by these evidences, is simple: for anyone seeking performance and recovery, personalized nutrition is not a luxury—it’s essential.
4. Technology can help
Today, technology allows us to monitor health and nutrition in an integrated and intelligent way.
Apps like Erakulis combine data on diet, sleep, physical activity, and wellbeing to provide personalized, real-time recommendations, helping people adjust habits practically and sustainably.
Artificial intelligence is already used to analyze physiological and training patterns, predicting needs and optimizing nutrition plans based on what the body truly requires.
Wearables that track heart rate, variability, sleep quality, and more allow nutrition to align with the body’s actual state, preventing both deficiencies and excesses.
Ultimately, AI and data are no longer distant concepts—they are simple, accessible tools that make caring for the body smarter, more precise, and more personal.
5. Small choices, big results
Taking care of your diet doesn’t need to be complicated. Start with simple steps:
- Fill half your plate with colorful foods: fruits, vegetables, and greens form the foundation of everything.
- Stay hydrated. Always carry a water bottle and drink before you feel thirsty.
- Prioritize sleep. Good rest helps regulate appetite, mood, and physical recovery.
- Avoid distractions while eating. Put down your phone, chew slowly, and pay attention to flavors—you’ll eat less and feel more satisfied.
- Plan at least one balanced meal per day. A nutritious breakfast can already make a difference.
- Swap ultra-processed foods for natural alternatives. A handful of nuts, a plain yogurt, or a piece of fruit are practical, nutritious snacks.
Nutrition is our operating system. With the right choices and the support of technology, we can live longer, think better, and feel our best every day.
This World Food Day, the message is simple: eat well, live better.
