This study aimed to investigate the relationship between food choices and periodontal health status (PHS) in adults who receive care through a public health system. We evaluated food preferences and periodontal status in a sample of 442 individuals with at least eight natural teeth. We employed the Food Frequency Questionnaire (FFQ) to assess food choices and the Periodontal Screening and Recording (PSR) instrument to evaluate periodontal health status during clinical appointments. Fisher's discriminant analysis was used to differentiate the participants according to PHS severity within three age-ranges (18-39; 40-59 and > 60 years-old). The results showed that the prevalence of overweight/obesity was high in all age groups (above 65%), and BMI increased with age, accompanied by an increase in the prevalence of chronic diseases. A lower preference for natural foods and a higher intake of processed and ultra-processed foods, along with a high waist circumference and diabetes, were associated with a poorer periodontal health status. In the 18-39 age group, a lower waist circumference was associated with healthier periodontal status. In the 40-59 age group, a worse periodontal status resulted from a higher frequency of diabetes, lower intake of green leafy vegetables, olive oil, and fruit, and higher intake of industrialized juice. Conversely, a healthier periodontal status was associated with a lower frequency of diabetes and higher intake of fruit and vegetables. In the > 60age group, the worst periodontal status was associated with male sex. Overall, the study highlights the possible beneficial role of a healthy diet in maintaining periodontal health, particularly for those who receive care through a public health system.
