Background: Obesity remains a public health problem. Recent, novel strategies suggest thefrequent inclusion of functional foods for better management of adiposity markers and obesityprevention. Numerous epidemiological and clinical studies demonstrate specific naturalfunctional foods of the Mediterranean Diet and innovative processed foods, enhanced withbioactive compounds, that they may present a possible beneficial role on this approach. Methods: In this cross-sectional epidemiological study, 319 Greeks and Cyprians, aged 18-75years were voluntary recruited in personal interviews. A validated Functional Food Frequency ofConsumption (FFFQ) was filled out, recording the frequency of selective functional foodsconsumption, following by anthropometric and body composition evaluations. Data collectionand statistical analysis were conducted, to assess the possible association of functional foodsfrequency of consumption with adiposity markers. Results: Olive oil is a main part of the daily diet of the representative sample of Greek andCyprian population and its frequency of intake was inversely related to body weight, taking intoaccount the lifestyle pattern and social parameters. Considering general habits andsociodemographic characteristics, Body Mass Index (BMI) was directly associated with thefrequency of consumption of split peas, turmeric, cinnamon, honey, whole wheat- and gluten-free pasta, as well as of gluten-free and enhanced bakeries. These functional food groups areconsumed by majority in a monthly basis, except of honey which is weekly consumed by themajority of the study population. Conclusion: The results suggest that the daily intake of olive oil, as the main characteristic ofMediterranean Diet, may be effective on body weight management. The frequency rise ofspecific spices, honey, functional pasta and bakeries consumption, may lead to increases inmarkers of adiposity. Further research is needed to safely conclude to these claims and theimplementation of nutritional treatment programs with functional foods may prove effective inthe prevention and management of obesity.
