🎯 Optimize your summer nutrition
Our coaches integrate seasonal nutrition into every Personal Training program.
Discover Personal TrainingWhy Summer Is a Key Nutritional Period
In summer, needs in water, electrolytes, and antioxidants increase significantly. Sweat rates can reach 1 to 2 liters per hour of effort, leading to massive losses of sodium, potassium, and magnesium. Fortunately, nature provides: summer fruits and vegetables contain on average 90 to 96% water and are loaded with essential minerals.
For athletes, summer often corresponds to the peak of the competitive season (athletics, trail running, triathlon, cycling, team sports in training camps). A diet rich in local produce loaded with water and antioxidants helps sustain intensity while accelerating recovery between sessions.

💡 Did you know?
Watermelon is one of the richest dietary sources of L-citrulline, an amino acid precursor of nitric oxide. Studies (notably Tarazona-Díaz et al., 2013) have shown that consuming 500 ml of watermelon juice before intense exercise can reduce 24h muscle soreness and improve perceived effort. It is also an excellent way to rehydrate after training, with its 92% water content and natural minerals.

Frequently Asked Questions
What are the best summer fruits for muscle recovery?
Watermelon (L-citrulline, hydration), blueberries and raspberries (anti-inflammatory anthocyanins), and late cherries are the summer champions. Watermelon is particularly interesting thanks to its documented effect on reducing 24h muscle soreness.
How to hydrate well with fruits and vegetables in summer?
Aim for 5 to 7 portions of water-rich fruits and vegetables per day (watermelon, melon, cucumber, tomato, zucchini). This can cover up to 20-30% of your daily water needs while providing natural electrolytes (potassium, magnesium).
How many portions of fruits and vegetables per day for an athlete in summer?
The WHO recommends a minimum of 5 portions (about 120g each). For athletes during summer, aiming for 7 to 10 portions per day is optimal to cover increased needs in water, electrolytes, vitamins, and antioxidants linked to heat and training volume.
Is local really better than imported organic?
Especially for summer fruits (tomatoes, peaches, apricots, berries), yes. These products are ideally picked at full ripeness, maximizing aromas, vitamin C, and polyphenols. A ripe local fruit almost always outperforms an imported organic fruit picked unripe.
Is cooked tomato better than raw tomato?
For lycopene, yes: cooking (sauce, coulis) increases its bioavailability 3 to 4 times. For vitamin C, however, raw tomato is better. The ideal is to vary both: raw in salad and cooked in sauce, ideally with a bit of olive oil that improves lycopene absorption.
How to store summer fruits and vegetables to keep their nutrients?
Tomatoes keep at room temperature (never in the fridge, which destroys their aromas). Berries should be refrigerated and only washed just before eating. Stone fruits (peaches, apricots) finish ripening at room temperature then move to the fridge. For winter stocks: freeze berries or jar tomatoes.
