Do You Want to Apply Your Nutrition Practice Knowledge to PEN Content?
PEN
® eNews is a monthly e-newsletter shared with the global PEN Community and created to help dietitians position themselves as leaders in evidence-based nutrition practice. In addition, users of the PEN System will find articles on the new evidence, resources and features available and how to maximize one's use of PEN.
Do You Want to Apply Your Nutrition Practice Knowledge to PEN Chronic Disease Content?
We need dietitians to review the latest evidence on dietitians' critical role in preventing, treating and managing chronic diseases.
We are looking for individuals to contribute approximately two hours to reviewing content on the effectiveness of dietary counselling and nutrition interventions for chronic disease.
Reviewers will be acknowledged in the published content and can download a Letter of Contribution summarizing their contributions for their professional portfolio.
Are you interested? Email coordinator@pennutrition.com by January 26th, 2024.

Age-related Eye Diseases and Dietary Patterns
The Question
What dietary patterns reduce the risk or slow the progression of age-related eye diseases (e.g. macular degeneration, glaucoma, diabetic retinopathy, cataracts)?
The Recommendation
Mediterranean Dietary Pattern
A Mediterranean diet may reduce the risk and progression of age-related macular degeneration (AMD) and may protect against diabetic retinopathy. It may not have any effect on the risk for glaucoma or cataracts, although there is a general lack of evidence for these eye diseases. Evidence for dry eye syndrome is inconsistent.
Asian Dietary Pattern
An Asian dietary pattern may reduce the risk and progression of AMD.
Other Dietary Patterns
Dietary patterns that are high in grains, fish, poultry, vegetables and nuts and low in red meat may slow the progression of AMD.
The Evidence
A 2023 systematic review of 18 studies (three RCTs, 15 observational) found that a Mediterranean diet reduced the risk of the development and progression of AMD and protected against diabetic retinopathy. The authors found no effect on glaucoma or cataracts (although they noted an overall lack of research) and inconsistent results for dry eye syndrome. Results may be limited by the exclusion of studies published in a language other than English and by the heterogeneity of study designs, measurement of adherence to a Mediterranean diet, and criteria used to diagnose each of the age-related eye diseases.
Results from a 2019 systematic review of two observational studies suggested that an Asian dietary pattern and dietary patterns low in red meat and high in grains, fish, poultry, vegetables and nuts reduced the risk of the development and progression of AMD while a Western dietary pattern increased the risk. Results may be limited by the low number of studies conducted on this topic and by recall bias associated with the use of food frequency questionnaires to assess dietary intake.
Grade of Evidence C
The Remarks
In the included studies, a Mediterranean dietary pattern encouraged high intakes of vegetables, nuts, cereal grains, fruit, beans and olive oil; a moderate intake of dairy products, poultry, fish and red wine; and a low intake of red meat and sugary foods. An Asian dietary pattern was high in fruit, vegetables (including tomatoes), legumes, whole grains and seafood. A Western dietary pattern was high in red and processed meat, eggs, high-fat dairy products, fried potatoes and refined grains.
Mediterranean and Asian dietary patterns may promote eye health because they emphasize foods that are high in antioxidants (e.g. vegetables, fruit, whole grains, nuts, seafood) and limit pro-inflammatory foods (e.g. red meat, sugary foods), thereby reducing the inflammation that can contribute to several age-related eye diseases.

Practice Guidance Toolkits - There for you!
Practice guidance toolkits make access to essential information on nutrition assessment, diagnosis, intervention, monitoring, associated tools and education materials based on nutrition-related conditions/diseases more 'up-front' and easier to retrieve. The toolkits present information in a format consistent with Nutrition Care Process Terminology (NCPT) with direct access to succinct information that dietitians use in their practice. The toolkits are a stand-alone tool used primarily for clinical knowledge pathways and also include the associated Summary of Recommendations and Evidence.
To find toolkits on the PEN home page, click on the Toolkits icon, which leads to all of the available toolkits.
They can also be found on the Knowledge Pathways Table of Contents page. Click on any of the icons under the Practice Guidance Toolkit column. Alternatively, within a knowledge pathway, click on the “Toolkit “ tab on the right-hand side of the page. The Toolkit tab will only display as an option if the knowledge pathway has a toolkit.
Helpful Features in the Toolkits
- Click on any of the items on the Table of Contents on the right-hand side of a toolkit to get quick, direct access to any section within the toolkit.
- Flags! Where information is specific to a particular country, you can see only your country’s information or view other’s information as well. Simply click the box at the top of the page for the country information that you would like to view, and it will be displayed (or alternatively unclick the box to hide it).
