The estimated phytoestrogens in the diet of the population correspond to the following groups: (1) isoflavenes: daidzein, genistein, formononetin and biochanin A; (2) coumestans: coumestrol; (3) lignans: enterolactone, enterodiol, matairesinol, and seciosolariciresinol. The average food servings were estimated from the semiquantitative FFQ, which was previously validated. The phytoestrogen intake per day was estimated by multiplying the amount of food reported in the semiquantitative FFQ (Table 2). \begin{table}

Table 2: Foods (g day\({}^{-1}\)) used to estimate phytoestrogen. The value corresponding to the desired phytoestrogen is expressed in \(\mu\)g day\({}^{-1}\). Table 3 details the mean amounts and standard deviations of the daily intake of phytoestrogens, following the classification by food groups. Table 2 does not include foods of animal origin (meat, eggs, fish, and dairy products) and sweets and fats since their phytoestrogen values have not been published so far; it is likely that, in raw foods, they are not present in these types of compounds. Average food intake according to the classification by group is expressed in g day\({}^{-1}\). Table 2 shows that the fruit groups had the highest average intake (241.75 g day\({}^{-1}\)), followed by vegetables (207.23 g day\({}^{-1}\)), cereals (120.09 g day\({}^{-1}\)), and legumes (46.54 g day\({}^{-1}\)). The participants do not consider the consumption of soybean and its derivatives of interest, not reaching 0.5% of the population, with only sporadic mention (less than 1 v/month), while the intake of nuts (7.63 g day\({}^{-1}\)), sweets, and candies accounts for 29.43 g day\({}^{-1}\), and these groups correspond to several others, for example, pizza. Burritos, included as a potential source of phytoestrogens, present mean intake values of 130.97 g day\({}^{-1}\). The
