Targeting DNA-methylation Fingerprints Linked to Ultra-Processed Foods Consumption to Prevent Non-communicable Diseases: the METHYL-UP Study

"A nutritional intervention program aimed to reduce UPF consumption. Nutritional intervention will not modify basal caloric intake but will record energy intake along the intervention. Nutritional counseling will be based on nutritional educational material such as encouraged and discouraged food items, recipes, menus and food shopping lists based on unprocessed or minimally processed foods.~Total intervention will last 6 months for both groups. During the intervention phase, a monthly interview with nutritionist/dietitian is scheduled. Face-to-face interviews will be carried out in months 2 and 4. Phone interviews will be carried out in months 1, 3 and 5. In the baseline and final visits (months 0 and 6) a sample and data collection will be performed."
