A study in mice has found that high doses of the sweetener sucralose can reduce the immune response and, under certain laboratory conditions, alter its action against infections or tumours. The results are published in the journal Nature.
A review of studies of more than 700,000 women has estimated that those who follow a Mediterranean diet faithfully have about a 25% lower risk of cardiovascular disease and death. This effect is greater than had been found in other studies, many of which included a majority of men and did not differentiate results by sex. According to the authors, the study underscores the need for this type of targeted analysis. The results are published in the journal Heart.
An analysis published in Nature Climate Change estimates that food consumption worldwide could add 1°C to global warming by 2100. The study also says that more than half of this warming could be avoided by adopting a healthy diet, improving food system practices, and reducing food waste.
A study has associated the consumption of the sweetener erythritol with an increased risk of cardiovascular disease, specifically myocardial infarction and stroke. The data are published in the journal Nature Medicine.
Available studies show no difference in the risk of different types of fracture between those who take calcium supplements and those who do not, according to a report by the Iberoamerican Cochrane Centre via Nutrimedia. According to the report, these supplements have side-effects and do not provide benefits in the general population and are therefore only recommended for people living in residential homes or other institutions.
Research involving 10,775 adults shows that a higher percentage of daily energy intake from ultra-processed foods was associated with cognitive impairment. The results are published in the journal JAMA Neurology.
A ketogenic diet, high in fat and low in carbohydrates, could increase platelet production and alleviate the low platelet counts caused by chemotherapy treatments. This is the finding of a small study published in the journal Science Translational Medicine.
Research published in the American Journal of Preventive Medicine has modelled the impact of ultra-processed food consumption on premature and preventable deaths in Brazil in 2019. According to the research, increased intake of these foods was associated with more than 10% of premature deaths in Brazil in 2019, representing about 57,000 deaths.
A study has associated the consumption of a high-fat diet in pregnant primates with alterations in the development of immune cells in the bone marrow of the foetuses. The results are published in the journal Stem Cell Reports.
Research published in Science concludes that mice that feed at night - the active phase of their daily circadian cycle - burn more calories, mitigating the development of obesity.
