Consumer objective and subjective knowledge about healthy foods: An approach to promote healthy lifestyle choices in South Africa.

Unhealthy food choices and consumption, coupled with sedentary lifestyles among consumers, intensify public health concerns regarding the quadruple disease burden, despite Primary Health Care (PHC) policy. However, the current relationship between consumer knowledge about healthy foods and following a healthy lifestyle needs to be explored. Our study, therefore, aimed to determine the association between consumers' subjective and objective knowledge about healthy foods and various healthy lifestyle choices.

The Influence of Mode of Instruction (Recorded Versus In-Person Lecture) on Student Achievement on Written Examinations in a Veterinary Clinical Toxicology Course.

The use of recorded on-line lecture presentation has increased in recent years in veterinary medical education. The effects of recorded on-line lectures on student knowledge acquisition are incompletely studied and there is very little information specifically addressing veterinary medical students. We studied the written examination performance of 373 third-year students spanning 4 calendar years (2017-2019, 2022) enrolled in a veterinary toxicology course which were exposed to either in-person lectures or recorded lectures of the exact same material.

Reference intervals for trace mineral and heavy metal concentrations in horse livers in the Netherlands.

We determined reference intervals (RIs) for concentrations of trace minerals and toxic elements based on liver samples from 122 apparently healthy horses at 2 slaughter facilities in the Netherlands. Samples were collected during the spring and fall of 2021, and the sex and age of the horses were registered upon sampling. Concentrations of arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, vanadium, and zinc were measured in liver samples using inductively coupled plasma-mass spectrometry (ICP-MS) after nitric acid digestion.

Zinc, Copper, and Manganese Homeostasis and Potential Trace Metal Accumulation in Dairy Cows: Longitudinal Study from Late Lactation to Subsequent Mid-Lactation.

Background: Trace metals are supplemented in cattle to prevent nutrient deficiencies. Levels supplemented to mitigate worst-case basal supply and availability scenarios can, however, result in trace metal intakes far above the nutritional requirements of dairy cows with high feed intakes.

Objectives: We evaluated Zn, Mn, and Cu balance in dairy cows from late lactation through the subsequent mid-lactation, a period of 24 wk characterized by large changes in dry matter intake.

Evaluation of hair analysis for determination of trace mineral status and exposure to toxic heavy metals in horses in the Netherlands.

Analysis of hair to gain insight into the trace mineral status and exposure to toxic heavy metals of horses is attractive because hair is an easily accessible sample material. To investigate the potential value of hair analysis in horses for determination of trace mineral and heavy metal concentrations, we analyzed mane hair and liver samples from 62 horses presented for slaughter at a facility in the Netherlands that receives horses from all regions of the country. Hair samples were cleaned in warm water.
