Historically, the constructs of inclusion, diversity, equity, and access (IDEA) have not been sufficiently considered or included in population health nutrition research and practice. Consequently, current nutrition assessment benchmarks and knowledge translation tools may not accurately or adequately reflect diversity in the Canadian population or produce meaningful dietary guidance. The purpose of this current opinion paper is to introduce the population health nutrition research and practice framework and explore the current application of IDEA within this framework. Recommendations are offered to incorporate the constructs of IDEA along the continuum of future nutrition research and services to improve population nutritional health., Competing Interests: The authors declare there are no competing interests.

Integrated knowledge translation (IKT) and community-based participatory research (CBPR) are recognized as effective approaches when Indigenous and non-Indigenous partners work together to focus on a common goal. The "Learning Circles: Local Healthy Food to School" (LC:LHF2S) study supported the development and implementation of Learning Circles (LC) in 4 Canadian Indigenous communities with the goal of improving local, community-based healthy food systems. Critical to the research process were annual gatherings (AG) where diverse stakeholders (researchers, Indigenous community members, and partners) visited each community to share knowledge, experiences, and provide support in the research process. Using a qualitative, descriptive method, this paper explores how the AG supported IKT across partners. Yearly interviews involving 19 total participants (with some participating multiple times across the 4 gatherings) elicited their AG experiences in supporting local LC:LHF2S. Three themes with multiple sub-themes were identified: (a) setting the stage for IKT (importance of in-person gatherings for building relationships across partners, learning from each other), (b) enabling meaningful engagement (aligning research with Indigenous values, addressing tensions and building trust over time, ensuring flexibility, and Indigenous involvement and leadership), and (c) supporting food system action at the local level (building local community engagement and understanding, and integrating support for implementation and scale-up of LC). This paper provides useful and practical examples of the principles of Indigenous-engaged IKT and CBPR in action in healthy, local, and traditional food initiatives. AG are a valuable IKT strategy to contribute to positive, transformative change and ethical research practice within Indigenous communities.

Guidance from Health Canada to limit highly processed foods (HPF) seeks to ensure that Canadians remain within intake recommendations for nutrients of concern. However, HPF can contribute to dietary requirements of specific populations. The Canadian Nutrition Society and Institute for the Advancement of Food and Nutritional Sciences convened speakers for a Food for Health workshop in 2021 to provide evidence and perspectives from government, industry, and healthcare on reasons for advocating limits and potential unintended consequences of limiting HPF, and implications and necessity of HPF in clinical settings. This paper discusses advantages and disadvantages of HPF explored at this workshop.

Indigenous communities in Canada are concerned about the health of their youth and the reclamation of traditional food-related skills amongst their people. Food sovereignty has an integral role in food and nutrition security, and the path to Indigenous self-determination. Learning Circles: Local Healthy Food to School (LC:LHF2S) was a community engagement model that aimed to enhance access to local, healthy, and traditional foods for youth. In each of four First Nations communities, a Learning Circle Evaluation Facilitator worked to plan and implement activities, build on community strengths, and promote partnerships. This paper describes how the model was perceived to support food sovereignty. Data included interviews, process reporting, and school surveys, and was analyzed according to pillars effective for the development of food sovereignty in Indigenous communities. Goals set by two communities incorporated food sovereignty principles, and in each community capacity-building work furthered the development of a more autonomous food system. There were many examples of a transition to greater food sovereignty, local food production, and consumption. Indigenous governance was an important theme and was influential in a community's success. The model appears to be an adaptable strategy to support the development of food sovereignty in First Nations communities. Novelty : LC:LHF2S was a community engagement model that aimed to enhance access to local, healthy, and traditional foods for youth. The model is an adaptable strategy to support the development of food sovereignty in First Nations communities.

Evidence-based guidelines represent the highest level of scientific evidence to identify best practices for clinical/public health. However, the availability of guidelines do not guarantee their use, targeted knowledge translation strategies and tools are necessary to help promote uptake. Following publication of the 2019 Canadian Guideline for Physical Activity throughout Pregnancy , the Get Active Questionnaire for Pregnancy , and an associated Health Care Provider Consultation Form for Prenatal Physical Activity were developed to promote guideline adoption and use amongst pregnant individuals and health care providers. This paper describes the process of developing these tools. First, a survey was administered to qualified exercise professionals to identify the barriers and facilitators in using existing prenatal exercise screening tools. A Working Group of researchers and stakeholders then convened to develop an evidence-informed exercise pre-participation screening tool for pregnant individuals, building from previous tool and survey findings. Finally, end-user feedback was solicited through a survey and key informant interviews to ensure tools are feasible and acceptable to use in practice. The uptake and use of these documents by pregnant individuals, exercise, and health care professionals will be assessed in future studies. Novelty: Evidence supports the safety/benefits of exercise for most pregnant individuals; however, exercise is not recommended for a small number of individuals with specific medical conditions. The Get Active Questionnaire for Pregnancy and Health Care Provider Consultation Form for Physical Activity during Pregnancy identify individuals where prenatal exercise may pose a risk, while reducing barriers to physical activity participation for the majority of pregnant individuals.

After over seven decades of neuroscience research, it is now well established that γ-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. In this paper dedicated to Krešimir Krnjević (1927-2021), a pioneer and leader in neuroscience, we briefly highlight the fundamental contributions he made in identifying GABA as an inhibitory neurotransmitter in the brain and our personal interactions with him. Of note, between 1972 and 1978 Dr. Krnjević was a highly reputed Chief Editor of the Canadian Journal of Physiology and Pharmacology .
