The latest research on cognitive health has found a surprising connection between egg consumption and improved cognitive function, particularly in women. According to a study published in the journal Nutrients, women who ate eggs more frequently experienced less decline in semantic memory and executive function over a four-year period.

The study, led by Donna Kritz-Silverstein, PhD, from the University of California San Diego, analyzed data from 890 adults over 55 years old who participated in the Rancho Bernardo Study. Participants reported their egg intake through food frequency questionnaires, and their cognitive performance was assessed through various tests.

Results showed that women who consumed eggs more frequently had a lower decline in cognitive function compared to those who rarely ate eggs. Every increase in egg consumption category was associated with a decrease in cognitive decline by 0.1, indicating a potential protective effect of eggs on cognitive health.

While the study did not find similar associations in men, the researchers suggested that factors such as diabetes, education, exercise, smoking, and alcohol consumption may have influenced the results. The study also pointed out that the participants’ homogeneity, predominantly white and highly educated, may have limited the generalizability of the findings.

Despite the limitations, the researchers noted that eggs contain nutrients beneficial for brain health, such as protein, choline, and carotenoids, which could explain their potential cognitive benefits. Future research may include brain imaging to further understand how egg consumption affects cognitive performance.

In conclusion, while eggs may play a role in maintaining cognitive function, experts recommend a balanced diet rich in antioxidants, whole foods, and nutrients known to support brain health. Ultimately, the key to supporting cognitive health lies in moderation and variety in food choices. So, as registered dietitian Lindsay Malone advises, “Don’t put all your eggs in one basket.”
