MedicalResearch.com: What is the background for this study? 

Response: Cholesterol was excluded from the recent dietary guidelines, but research remains unclear about eggs and cholesterol on health.

MedicalResearch.com: What are the main findings? Why is the advice about the benefits/harms regarding egg intake often so conflicting?

Response: Higher egg intake and cholesterol intake were related to increased risk of mortality. Individual observational studies can be confusing as the overall results depend on the baseline intake of the population and adjustment for confounders.  

MedicalResearch.com: What should readers take away from your report?

Response: Balance and moderation is the key. Complete avoidance of eggs and egg yolks is not recommended because they have healthy nutrients as well. Extremely high intake of any single food may lead to imbalances. 3-4 eggs a week appears healthy but intakes of multiple eggs/day are probably not a good idea.  

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We need to clarify what exactly it is about too many eggs that is causing the risk. Healthy metabolism depends on a complex interaction of nutrients.

Children Need Both Naps and Overnight Sleep to Process Emotional Memories

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We know that in young adults, sleep contributes to emotion processing. We wondered if naps work similarly for preschool children.  To look at this, we had children learn an emotional memory task and then either take a nap or stay awake.  We then tested their memory after that interval and again the next day.

We found that when children napped, they had better memory for those items the next day than if they did not nap.  That the naps seem to support memory (even if in a delayed fashion) seems consistent with the observation of parents and preschool teachers that children are often emotionally dysregulated if they do not nap.
