Introduction: The nutritional quality of restaurant foods in Canada is not monitored by government and limited research has evaluated the nutrient content of these foods. Given the increasing proportion of foods consumed outside the home, this study aims to assess levels of nutrients of public health concern in Canadian fast-food and sit-down restaurant menu items.
Methods: Levels of calories, saturated fat, sodium, and sugar of 10,285 menu items from 90 national chain restaurants in Canada were assessed. Data were collected in 2016, extracted and analyzed between 2018 and 2020, and presented overall and by category. Levels in fast-food and sit-down restaurant establishments were compared.
Results: Overall mean levels of saturated fat, sodium, and sugar were high. Entrées contained on average 52% of the total daily value for sodium (1,256 mg/serving) and 45% of the daily value for saturated fat (8.9 g/serving). Beverages and desserts had high levels of total sugar (mean=44 g and 32 g/serving, respectively) but tended to be low in sodium. Sit-down restaurant items had significantly (p≤0.0001) higher levels of calories, saturated fat, and sodium overall, although fast-food restaurant items had higher average sugar levels because of the higher number of beverage and dessert items.
Conclusions: Levels of nutrients of concern in Canadian menu items are excessive among most food categories. As the frequency of eating out in restaurants rises, government policies to promote reformulation and increase transparency of the nutritional content of these items are required to reduce their negative impact on public health.

Despite growing awareness of their importance in soil ecology, the genetic and physiological traits of bacterial predators are still relatively poorly understood. In the course of a predator evolution experiment, we identified a class of genotypes leading to enhanced predation against diverse species. RNA-seq analysis demonstrated that this phenotype is linked to the constitutive activation of a predation-specific program.

Desorption electrospray ionization mass spectrometry imaging (DESI-MSI) provides direct analytical readouts of small molecules that can be used to characterize the metabolic phenotypes of genetically engineered bacteria. In an effort to accelerate the time frame associated with the screening of mutant libraries, we have developed a high-throughput DESI-MSI analytical workflow implementing a single raster line-scan strategy that facilitates the collection of location-resolved molecular information from engineered strains on a subminute time scale. Evaluation of this "Fast-Pass" DESI-MSI phenotyping workflow on analytical standards demonstrated the capability of acquiring full metabolic profiling information with a throughput of ∼40 s per sample.

An obligately anaerobic, spore-forming sulphate-reducing bacterium, strain SB140, was isolated from a long-term continuous enrichment culture that was inoculated with peat soil from an acidic fen. Cells were immotile, slightly curved rods that stained Gram-negative. The optimum temperature for growth was 28 °C.

A Gram-stain-positive, facultatively anaerobic, rod-shaped strain, designated SPB1-3, was isolated from tree bark. This strain exhibited heterofermentative production of dl-lactic acid from glucose. Optimal growth was observed at 25-40 °C, pH 4.

This study tested the effects of propylene glycol (PG) on the fatty acid composition of Akkaraman lambs in three different anatomical depot locations (ADLs). Twenty-four lambs were assigned to a randomized complete block design comprising three groups of 8 animals as follows: Con, 1.5%, body weight (BW) (PG1.
