Table 1 presents the general socio-demographic characteristics of the participants. A total of 250 participants were recruited to the study, while 244 completed the study, specifically 145 women (59.43%) and 99 men (40.57%). Of the participants, 75.41% were aged between 18-35 years old, 54.30% came from Lemnos Island (Northern Greece), while 44.70% were from central Greece (Athens, Chalkida). No statistically significant difference was observed in mean polyphenol intake between the two genders (\(p\) = 0.324) and between different ages (\(p\) = 0.965). The mean daily intake of polyphenols is estimated at 1905 mg. Table 2 presents the percentage of mean daily polyphenol intake in mg per day. Most of the participants (40.63%) were consuming 1000-2000 mg polyphenols per day, while 33.93% > 2000 mg and 25.45% below 1000 mg.  
Table 2 also presents the degree of Mediterranean diet adherence. Only 14.00% of the participants had high adherence to the Mediterranean diet, while most of them (82.00%) appeared moderate, and 4.17% had low adherence. \begin{table}

Table 2: Mean daily polyphenols intake and Mediterranean diet adherence of the participants. Table 3 present the association of anthropometric indices with low, moderate, or high polyphenol intake. Participants who were consuming low intakes of polyphenols (<1000 mg) appeared to have significantly increased body water content, in comparison with participants with high intakes (>2000 mg) (\(p\) = 0.024). Moderate polyphenols' intake (1000-2000 mg) was associated with significantly reduced waist-to-hip circumference, compared with low polyphenols' intake (\(p\) = 0.027). Furthermore, moderate adherence to the Mediterranean diet, correlated with significantly higher polyphenols intake in comparison with low adherence (\(p\) = 0.016). Table 3 also presents the association of anthropometric indices with low, moderate, or high Mediterranean diet adherence. Participants who had moderate or high adherence to the Mediterranean diet appeared to have a significantly decreased ratio of waist circumference and hip circumference (\(p\) = 0.032, \(p\) = 0.004). Higher Med Diet Score was also significantly correlated with reduced Body Mass Index (Low- Moderate: \(p\) = 0.021 High-Low: \(p\) = 0.017) and Basal Metabolic Rate (Low- Moderate: \(p\) = 0.003, High-Low: \(p\) = 0.005). Table 4 presents associations between the consumption of specific foods rich in polyphenols with anthropometric indices. Specifically, increased tomato and sour cherry consumption was correlated with decreased body fat (\(p\) = 0.0222, \(p\) = 0.024). Increased red wine and sour cherry consumption were associated with decreased BMI (\(p\) = 0.003, \(p\) = 0.018). Waist circumference was significantly decreased after higher consumption of carrot, dark chocolate, and cocoa powder (\(p\) = 0.022, \(p\) = 0.003, \(p\) = 0.022), rather than lower consumption. Hip circumference was significantly decreased after higher consumption of red wine, strawberry, carrot, red pepper, and black tea (\(p\) = 0.03, \(p\) = 0.011, \(p\) = 0.015, \(p\) = 0.02, \(p\) = 0.009), rather than lower consumption.
