BACKGROUND: Appropriate nutrition is important to maintain health, growth, and development of adolescent athlete performance. OBJECTIVE: To evaluate the impact of nutritional intervention (NI) promoting Mediterranean diet (MD), on food consumption, and adherence to MD, in scholar adolescent athletes. METHODS: Eighty athletes (Females/Males, 39/41) aged 15±1 years participated to NI. MD Adherence was assessed, using Kidmed index, at baseline, and at 6 months. Food intake was evaluated by 24-hour recall at baseline, and at four NI times. RESULTS: At baseline, 61% of athletes had poor MD adherence, and after NI, this value decreased to 10%. At 6 months of NI, 73% of males vs 46% of females had good MD adherence (≥8). Energy intake represented 2369 Kcal/d, at baseline, and was less than recommended value. After NI, significant increase was observed in energy intake (p = 0.001). Mean fiber intake (19 and 21 g/d in females and males, respectively) was less than adequate intake (26/38 g/d), but increased after NI (p = 0.000). Enhancement was noted in total, and complex carbohydrates, and total proteins, and values were increased with time (p = 0.000, p = 0.000, p = 0.003). CONCLUSION: Nutritional intervention, based on Mediterranean diet, improves total energy, and macronutrients intake, and increases MD adherence scores in adolescents athletes.
