Functional Food Containing Probiotics–Differences in Health Benefits Among Men and Women

The consumption of functional foods, especially enriched by probiotics, is appreciated by a growing group of consumers. In this comprehensive review, the comparison of food probiotics’ health advantages between adult healthy women and healthy men was demonstrated with the aim of indicating the target group of consumers. Based on clinical studies and meta-analyses, in the context of sex differences, the impact of functional foods with probiotics on selected disease development and disease course, as well as on the potential health benefits, was discussed. Significantly population-related and most common health abnormalities, such as obesity, metabolic disorders, hypertension, irritable bowel syndrome, and functional gastrointestinal disorders, were analysed. There is a sex-dependent variety of gut microorganisms, and a greater diversity of the gut microbiome is found in women. The major differences between men and women considered in the study included higher prevalence of irritable bowel syndrome and obesity in women, a different lipid profile, and different age-related hypertension occurrence in both groups. Life expectancy has also been taken into account. According to the statistical data, women live longer, experience more health problems in the course of life, and therefore will probably more frequently seek functional food. In general, consumption of functional foods should be supported and recommended for the entire population. The open questions that need to be clarified are if the sex-dependent strategy is justified for choosing specified functional foods and probiotic strains.
