Abstract
Purpose: Major changes were made to Canada's Food Guide (CFG) in 2019. This study aimed to understand the perceptions of older adults toward this newest version.Methods: Older adults were invited to participate via newsletters sent to older adults and retirees' organizations in the Province of Quebec. Participants completed an online survey about their baseline familiarity with the 2019 CFG using a 5-point Likert scale and took part in an individual semi-structured online interview, which explored their perceptions toward the 2019 CFG. A thematic qualitative analysis of the interview transcripts was performed.Results: Fifty-eight older adults (>65 years, 30 women, 28 men, including 19 consumers and 39 non-consumers of plant-based protein (PBP) foods) participated in the study. Older adults were mostly familiar with the 2019 CFG and had a positive perception of its features. They appreciated the design, proposed recipes, and healthy eating recommendations. Perceptions about the three food groups were mixed, mainly regarding the decreased emphasis on dairy products. Some appreciated that animal proteins were less prominent, while others raised issues on how to integrate PBP into their diet. Perceptions appeared to be influenced by sex and PBP consumption.Conclusion: Older adults in the Province of Quebec view most of the 2019 CFG recommendations positively. Our observations may be useful to dietitians and public health practitioners when developing strategies to improve adherence.

Abstract
CONTEXT Body fat distribution is a risk factor for obesity-associated comorbidities, and adipose tissue dysfunction plays a role in this association. In humans, there is a sex difference in body fat distribution, and steroid hormones are known to regulate several cellular processes within adipose tissue. OBJECTIVE Our aim was to investigate if intra-adipose steroid concentration and expression or activity of steroidogenic enzymes were associated with features of adipose tissue dysfunction in individuals with severe obesity. METHODS Samples from 40 bariatric candidates (31 women, 9 men) were included in the study. Visceral (VAT) and subcutaneous adipose tissue (SAT) were collected during surgery. Adipose tissue morphology was measured by a combination of histological staining and semi-automated quantification. Following extraction, intra-adipose and plasma steroid concentrations were determined by liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). Aromatase activity was estimated using product over substrate ratio, while AKR1C2 activity was measured directly by fluorogenic probe. Gene expression was measured by quantitative PCR. RESULTS VAT aromatase activity was positively associated with VAT adipocyte hypertrophy (P valueadj < 0.01) and negatively with plasma high-density lipoprotein (HDL)-cholesterol (P valueadj < 0.01), while SAT aromatase activity predicted dyslipidemia in women even after adjustment for waist circumference, age, and hormonal contraceptive use. We additionally compared women with high and low visceral adiposity index (VAI) and found that VAT excess is characterized by adipose tissue dysfunction, increased androgen catabolism mirrored by increased AKR1C2 activity, and higher aromatase expression and activity indices. CONCLUSION In women, increased androgen catabolism or aromatization is associated with visceral adiposity and adipose tissue dysfunction.

Abstract
Severe obesity is associated with major health issues and bariatric surgery is still the only treatment to offer significant and durable weight loss. Assessment of dietary intakes is an important component of the bariatric surgery process. Objective: To document the dietary assessment tools that have been used with patients targeted for bariatric surgery and patients who had bariatric surgery and explore the extent to which these tools have been validated. Methods: A literature search was conducted to identify studies that used a dietary assessment tool with patients targeted for bariatric surgery or who had bariatric surgery. Results: 108 studies were included. Among all studies included, 27 used a dietary assessment tool that had been validated either as part of the study per se (n = 11) or in a previous study (n = 16). Every tool validated per se in the cited studies was validated among a bariatric population, while none of the tools validated in previous studies were validated in this population. Conclusion: Few studies in bariatric populations used a dietary assessment tool that had been validated in this population. Additional studies are needed to develop valid and robust dietary assessment tools to improve the quality of nutritional studies among bariatric patients.
