This cross-sectional cohort study aimed to examine associations between chrono-nutrition behaviours and CF in adults aged 45-65 years living in Cyprus. Chrono-nutrition, including misalignments between actual and preferred eating times, Mediterranean diet (MD) adherence, sleep and physical activity were assessed using validated questionnaires. Computerised neurocognitive remote testing was used to derive standard normalised age-matched scores for composite memory, psychomotor speed, cognitive flexibility, complex attention, reaction time and neurocognitive index. Education, marital status, smoking, body mass index, chronic disease diagnosis and religious fasting were also assessed. Adjusted multivariate ordinal logistic regression was used to assess each chrono-nutrition variable against each cognitive outcome.

Antinutrients, including protease inhibitors, amylase inhibitors, phytic acid, lectins, saponins, tannins, cyanogenic glycosides, oxalic acid, polyphenols, goitrogens and pyrimidine glycosides, are described, encompassing various aspects such as their structural characteristics, analytical detection methods, distribution, physiological impacts and strategies for mitigation or elimination. Specifically, our review concentrates on assessing the presence of antinutrients in plant-based food products and the primary ingredients, categorised into five distinct groups, cereals, pseudocereals, pulses, seeds and nuts, which are commonly used in their production. Among these categories, legumes are identified as the richest source of anti-nutritional compounds, followed by cereal grains. However, certain pseudocereals, seeds and nuts also demonstrate high levels of specific antinutrients. While antinutrients are generally regarded as harmful to nutrient absorption, recent studies have revealed some potential health benefits associated with them. Therefore, further in vivo research is essential to elucidate the behaviour of antinutritional compounds within the human body.

Dyslipidemia, defined by abnormal lipid concentrations, performs a pivotal role in the onset of cardiovascular diseases, especially atherosclerosis. Dietary strategies and other nonpharmacological interventions are crucial for the management of dyslipidemia. Açaí (Euterpe oleracea), a fruit native to the Amazon, is recognised for its antioxidant properties and potential impact on lipid metabolism. This systematic review and meta-analysis aimed to assess the impact of açaí consumption on lipid profile markers. A systematic search was performed across several databases, including MEDLINE/PubMed, EMBASE, Web of Science and Scopus. We included non-randomised, randomised, no blind, blind and control trials involving adult participants who received açaí in any form. The outcome measures included triglycerides, total cholesterol, LDL-c and HDL-c. The screening of studies and data extraction were independently conducted by four reviewers. The risk of bias was evaluated using the Cochrane Risk of Bias tool, and meta-analyses were completed where applicable. Out of 188 identified studies, 8 met the inclusion criteria. Meta-analysis of 411 participants displayed no significant effect of açaí on LDL-c (MD = 6.06 mg/dL 95% CI: -0.03, 12.48, p = 0.06), HDL-c (MD = 0.30 mg/dL 95% CI: -1.54, 2.13, p = 0.75), total cholesterol (MD = 2.94 mg/dL 95% CI: -6.44, 12.31, p = 0.54) and triglycerides (MD = 2.05 mg/dL 95% CI: 1.79, 2.28, p = 0.59). Additionally, açaí consumption was related to a significant reduction in total lipids (MD = -9.80 g, 95% CI: -13.94 to -5.66, p < 0.001). GRADE evaluation pointed to low/very low certainty of evidence. Açaí consumption may lessen total lipid levels, but no significant effect was noted for cholesterol parameters and triglycerides.

Bootstrapped correlations showed that higher fruit and vegetable and omega-3 intake were associated with lower gastrointestinal symptom and depression scores, but effects were weak. Furthermore, higher occurrence of gastrointestinal symptoms was moderately associated with higher depression scores. Results from a series of exploratory mediation analyses suggested that gastrointestinal symptoms mediated the relationship between lifestyle factors and depression status.

Further optimisations imposing significant reductions in GHGE indicate important environmental and nutritional co-benefits can be achieved through the WHO guidelines, while maintaining diet affordability. In the WHO scenario, the maximum diet-related GHGE reduction policymakers could aim for is 30%, since above this threshold, recommended diets would deviate considerably from observed patterns.
