Szczegółowy opis
150 vegan, vegetarian, semi-vegetarian women (18-64 years) will be recruited among patients attending the European Institute of Oncology for prevention visits or oncological follow-up. The study will include a baseline visit and a 3-month follow-up visit, with an interim telephone contact.
At baseline, nutritional adequacy and diet quality will be assessed, followed by a personalized nutritional counselling aimed at improving dietary variety, ensuring adequate nutrient intake, and promoting an active lifestyle. The intervention will be based on a vegetarian adaptation of the Healthy Eating Plate and aligned with national and international guidelines (CREA,2019; WCRF, 2018).
During study visits, anthropometric measurements (height, weight, waist and hip circumferences), body composition (BIVA), and blood samples will be collected. Dietary intake will be evaluated via a 3-day food records. Validated questionnaires will be administered to assess physical activity (IPAQ-SF), adherence to the Mediterranean diet (QueMD), and quality of life (VEGQOL). Additionally, vegetarian diet quality and lifestyle will be evaluated using the Vegetarian Lifestyle Index.
Nutritional adequacy will be determined by comparing dietary intake and blood biomarkers with Italian Dietary Reference Values (DRVs; SINU 2024).

Eksperymentalny: vegetarian study population
The study population comprises 150 women (18-64 years) adhering to plant-based diets (vegan, vegetarian, or semi-vegetarian), including both healthy individuals and those with a history or high risk of cancer recruited at the European Institute of Oncology (Milan, IT)
|
Participants will receive personalized nutritional counseling by registered dietitians based on blood tests and 3-day food records, focusing on improving diet variety and optimizing intake of critical nutrients.
Additionally, lifestyle advice will be provided to increase physical activity and reduce sedentary behavior.

Survey on nutritional adequacy of participants' diet at baseline
Ramy czasowe: Baseline
|
Nutritional adequacy evaluated through blood biomarkers and dietary intake, assessed via 3-day food records.
Nutrient data will be referenced against the Italian Dietary Reference Values (DRVs).
Nutritional adequacy will be quantified by calculating the Nutrient Adequacy Ratio (NAR) and the Mean Adequacy Ratio (MAR).
The NAR represents the ratio of an individual's nutrient intake to the corresponding Italian DRV for their age group, while the MAR is the average of all calculated NARs.
Both indices will be expressed on a scale from 0 to 1, where 0 indicates that nutrient requirements are not met and 1 indicates that they are fully met.
