Investigação Clínica em Nutrição

No âmbito desta linha de investigação procuramos identificar, compreender e avaliar como a saúde e a doença são influenciadas pela nutrição. 

Desenvolvemos projetos colaborativos nos setores da saúde, alimentação e desporto e estabelecendo parcerias com hospitais, unidades de saúde, indústria alimentar e farmacêutica, associações clínicas, federações desportivas, entre outros. Exploramos o comportamento alimentar assim como o consumo de alimentos e a ingestão de suplementos alimentares (incluindo nutrientes) no sentido de melhorar outcomes metabólicos e de criar novas intervenções e abordagens preventivas para a redução do risco das doenças crónicas.

  • ClinicalTrials.gov ID: NCT02975856 - Bioavailability of Red Wine Anthocyanins.
    (https://clinicaltrials.gov/ct2/show/study/NCT02975856?term=calhau&draw=2&rank=7)

    Anthocyanins (ANT) are water soluble pigments found in plants, flowers and fruits that are consumed as part of the human diet, many times in higher amounts than other flavonoid classes. Red wine is also an important source of anthocyanins, especially Mv3glc.
    Several epidemiological studies have suggested that the consumption of anthocyanin-rich foods, including the moderate consumption of red wine, is positively associated with the prevention of cardiovascular heart disease.
    It has become clear that the flavonoid bioactive forms in vivo are not necessarily those which occur in nature, but metabolites arising after absorption takes place.Therefore, studying the bioavailability of red wine ANT is very important to identify which metabolites (originated in vivo) can actually reach the target organs (and in which concentrations) and may be responsible for the postulated health benefits of red wine.

    Anthocyanins (ANT), a particular class of flavonoids that can be found in red wine and red fruits, have been associated with relevant health benefits. It has become clear that the flavonoid bioactive forms in vivo are not necessarily those which occur in nature, but metabolites arising from them after absorption. Therefore, it is important to identify which ANT metabolites are responsible for their health benefits. Since ANT can prevent/treat some of the metabolic features of obesity it is also crucial to study whether ANT bioavailability is not compromised in obesity.

  • ClinicalTrials.gov Identifier: NCT02608138 - Iogeneration
    It is well known that insufficient iodine intakes impairs the production of thyroid hormones, essential for cognitive development and healthy growth.
    Although the World Health Organization (WHO) promotes public health measures for an adequate iodine consumption, it is estimated that one in three school age children remain iodine deficient worldwide. Whereas there is no mandatory iodisation programs in Portugal, young infants are among the most vulnerable to iodine deficiency due to their special requirements.
    Therefore, the present study aims to evaluate iodine status in school age Portuguese children (6-12y), compare iodine status in children, cognitive outcomes and thyroid health and monitor the use of iodised salt in school canteens exploring potential implications in children's iodine status.
