To accelerate measurement of the water-holding capacity (WHC) of meat by the press method, video image analysis (VIA) and formulae were investigated. The areas of meat and meat liquid on filter paper were little affected by changes in the operating conditions of the VIA system. VIA is associated with greater repeatability, less variation due to operators and was less time consuming than planimetry. When VIA was applied to a variety of fresh meats (beef, pork, chicken and duck meat), it was possible to measure the areas of meat and liquid on filter paper under a translucent plastic plate, immediately after pressing, without drawing an outline of the meat area. VIA was also able to measure cooked meat. Drying on filter paper decreased the areas of meat and liquid slightly but hardly changed the meat/liquid area ratio. The meat/liquid area ratio was correlated (P < 0.01, r = 0.92) with the WHC measurements obtained by conventional formulae including sample moisture. VIA combined with mmeat/liquid ratio is a rapid stable and efficient technique for measuring WHC by the press method.

Background: Eclampsia is among the primary causes of maternal and perinatal morbidity and mortality in Zanzibar. Many women and men are not aware of the signs, symptoms and causes of eclampsia and may have different explanatory models. Therefore, this study aimed to describe the community understanding of pre-eclampsia, as a key stage to improve maternal and perinatal health in Unguja Island, Zanzibar.

As the global population continues to grow and the pressure on livestock and poultry supply increases, the oceans have become an increasingly important source of quality food for future generations. However, nutrient-rich aquatic product is susceptible to lipid oxidation during storage and transport, reducing its nutritional value and increasing safety risks. Therefore, identifying the specific effects of lipid oxidation on aquatic products has become particularly critical.

Background: The WHO considers anemia in pregnancy a severe public health issue when prevalence surpasses 40%. In response, we conducted a systematic review and meta-analysis to examine anemia among pregnant women in Egypt, focusing on its prevalence, determinants, and associated complications.
Methods: We conducted a systematic literature search for studies published between January 1, 2010, and August 18, 2024, to identify studies from Egypt reporting on anemia in pregnant women, including its prevalence, associated determinants, and complications.

Background: Wild game meat has over the years gained popularity across the globe as it is considered a food source with high protein content, low fat content, and a balanced composition of fatty acids and minerals, which are requirements for a healthy diet. Despite this popularity, there is a concern over its safety as many species of wildlife are reservoirs of zoonotic diseases including those of bacterial origin, more so antibiotic-resistant bacteria.
Methods: This study aimed to describe the prevalence of antibiotic-resistant bacteria in mammalian wild game, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
A reform of value-added taxes on foods can have health, environmental and economic benefits in Europe.

Fiscal policies can provide important incentives for encouraging the dietary changes needed to achieve global policy targets. Across Europe, the foods relevant to health and the environment often incur reduced but non-zero value-added tax (VAT) rates at about half the maximum rates, which allows for providing both incentives and disincentives. Integrating economic, health and environmental modelling, we show that reforming VAT rates on foods, including increasing rates on meat and dairy, and reducing VAT rates on fruits and vegetables can improve diets and result in health, environmental and economic benefits in most European countries.
