  • The contribution of precision nutrition intervention in subfertile couples
    Publication . Monteiro, Jéssica; Bicho, Manuel; Valente, Ana
    Background/Aim: Subfertility is characterized by a decrease in reproductive efficiency, which can result in delayed pregnancy, and affects one in six individuals during their lifetime. The present narrative review aims to evaluate the contribution of precision nutrition to changes in fertility in subfertile couples. Methods: The literature review was carried out through bibliographic research in the PubMed, Scopus, SciELO and Google Scholar databases. The following search criteria were applied: (1) original articles and narrative, systematic or meta-analytic reviews, and (2) the individual or combined use of the following keywords: “genetic variation”, “nutrigenetics”, “precision nutrition”, “couple’s subfertility”, and “couple’s infertility”. A preliminary reading of all the articles was carried out, and only those that best fit the themes and subthemes of the narrative review were selected. Results: Scientific evidence suggests that adherence to a healthy diet that follows the Mediterranean pattern is associated with increased fertility in women and improved semen quality in men, better metabolic health and reduced levels of inflammation and oxidative stress, as well as maintaining a healthy body weight. The integration of different tools, such as nutrigenetics, predictive biochemical analyses, intestinal microbiota tests and clinical nutrition software, used in precision nutrition interventions can contribute to providing information on how diet and genetics interact and how they can influence fertility. Conclusions: The adoption of a multidisciplinary and precision approach allows the design of dietary and lifestyle recommendations adapted to the specific characteristics and needs of couples with subfertility, thus optimizing reproductive health outcomes and achieving successful conception.

  • Meat consumption and availability for its reduction by health and environmental concerns : a pilot study
    Publication . Turnes, Andrea; Pereira, Paula; Cid, Helena; Valente, Ana
    (1) Background: Excessive meat consumption has raised multiple health and environmental concerns; however, there are no data on the population’s willingness to reduce its intake for these reasons. The current study aims to assess the frequency of meat intake and readiness to limit consumption due to concern about the impact on health and the environment in residents of the Lisbon metropolitan region. (2) Methods: This analytical cross-sectional observational study was carried out in 197 residents in the metropolitan region of Lisbon. The participants were divided into two groups by age (GI: 20–29 years; GII: 40–64 years). Meat consumption and willingness to reduce it were assessed through a questionnaire. (3) Results: Most participants (67%) reported not having knowledge about the ecological footprint of meat. Being a less frequent meat consumer (<1 time per day) is associated with a willingness 3.6 times higher (p < 0.001) to reduce meat consumption due to sensitivity to the impact on health and 4.0 times higher (p < 0.001) due to environmental reasons. (4) Conclusions: Lower meat consumption frequency was associated with reductions in this consumption for environmental and health reasons.
