Summary
Brief summary (as posted)
Despite their health benefits, vegetarian dietary patterns can lead to malnutrition and micronutrient deficiencies if improperly managed, especially in oncological settings. This survey assesses dietary quality and adequacy in 150 women (18-64 years), further examining how a threemonth nutritional counseling intervention influences body composition, physical activity, and quality of life.

- EXPERIMENTAL
- label
- vegetarian study population
- description
- 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)

- Other: personalized nutritional counseling
Primary outcomes (2)
- measure
- Survey on nutritional adequacy of participants' diet at baseline
- timeFrame
- Baseline
- description
- 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.
