          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.
        
        
        
        
        
        
                
                    
                    Nutritional Interventions for Sleep: Are They Helpful During (Peri)Menopause? 
The Question
 Can nutritional interventions (including dietary or herbal supplements) improve sleep during perimenopause and/or menopause?
Recommendation
Evidence does not suggest that any nutrition intervention objectively improves sleep in perimenopausal/ menopausal women. 
However, the following interventions showed subjective (e.g. questionnaires, sleep diaries, estimated sleep duration) improvements in sleep in some studies:
- Combined nutrition interventions (e.g. multiple concurrent interventions, such as omega-3 supplements plus yoga; 10/14 studies) 
- Combined herbal interventions (e.g. herbal formulas including more than one active ingredient, such as Panax ginseng, black cohosh, soy, and green tea extract; 8/11 studies)  
- Isoflavones (4/8 studies) 
- Soy (2/5 studies) 
- Black cohosh (2/3 studies) 
- Pollen (2/3 studies)  
- Melatonin (1/2 studies) 
- Purple yam (1/1 study) 
- Pomegranate seed oil (1/1 study) 
- JuicePLUS (1/1 study) 
- Jujube seed capsule (1/1 study) 
- Maca (1/1 study) 
- Proanthocyanin (1/1 study) 
- Salvia extract (1/1 study) 
Overall, the evidence on this topic is of low methodological quality and results should be interpreted with caution.
Remarks
The composition of many combined nutrition and herbal interventions were not defined.
The term “menopause” refers to the permanent end of menstruation. Specifically, menopause is established when 12 consecutive menstruation-free months have passed. “Perimenopause”, or the “menopausal transition”, is the time surrounding menopause, beginning at the onset of menopause symptoms and ending when menopause has been established.

                    Protein Needs During (Peri)Menopause
The Question
 Should dietary protein intake increase during perimenopause and/or menopause?
Recommendation
There is insufficient evidence to make a menopause-specific recommendation for protein intake in women. It would be prudent to encourage perimenopausal and menopausal women to meet national recommendations regarding protein intake.
Remarks
Risk of developing sarcopenia (i.e. age related loss of muscle mass, strength and function) has been estimated at 20% higher in women than in men. Risk of sarcopenia has been independently associated with menopause; changes in diet (e.g. decreased protein, restricted caloric intake leading to decreased macro- or micronutrient intake) and decreases in exercise that have also been associated with menopause and sarcopenia. Despite these associations, optimal dietary intervention strategies (e.g. optimal amounts of specific foods or nutrients) are not clear.

                    The NiMe Diet: What is it, and How Might it Affect Dietetic Practice?
Nutrition researchers and dietitians at the University of Alberta recently published a crossover randomized controlled trial (RCT) evaluating the effect of a diet they created to investigate whether they could restore industrialized gut microbiomes to an “ancestral” state. The NiMe Diet (Non-industrialized Microbiome Restore) is based on the traditional diet of people living in non-industrialized societies, modified to include only foods available in Canada. 
Additionally, the authors aimed to use L. reuteri to colonize the gut microbiomes of study participants. The authors chose L. reuteri as a target because it is not typically found in people with industrialized gut microbiomes but is dominant in the gut microbiomes of people from Papua New Guinea, who have non-industrialized gut microbiomes.
