A recent study published in the journal Nutrients suggests that consuming eggs It can help prevent cognitive impairmentespecially in older women. Cognitive decline, including memory loss and confusion, is a common aspect of aging. However, the study reveals that regular egg consumption may improve cognitive performance, especially in areas such as semantic memory and executive functioning, which includes skills such as self-control and flexibility.
The study looked at 890 adults over the age of 55, 357 men and 533 women, between 1988 and 1991. Participants were asked about their egg consumption habits via a food frequency questionnaire and their cognitive abilities were assessed during two separate visits, four to five years apart. Cognitive testing included assessments of language, memory, attention, recall, and mental flexibility.
The results indicated that men tended to eat more eggs than women: some consumed eggs between two and four times per week, while others did so more than five times per week. Women, on the other hand, ate eggs sparingly, between one and three times per month, or not at all. Despite this difference in egg consumption, the study found that women who ate eggs showed a slower rate of cognitive decline, especially in their semantic memory.
The researchers stressed that while egg consumption was associated with better cognitive outcomes in women, there were no claims that eggs directly improved brain healthHowever, the study confirmed that eating eggs does not negatively affect cognitive abilities and that regular consumption could play a role in maintaining mental acuity. The study therefore recommends incorporating eggs into the diet as a potential way to support brain function at a given age.
Other health benefits of eating eggs
Eggs are not only beneficial for cognitive health, but also offer other benefits:
– Rich in Protein: Eggs are an excellent source of high-quality protein, which helps with muscle repair and development. One large egg contains about 6 grams of protein, which is essential for maintaining muscle mass as we age.
– Good for eye health: Eggs contain antioxidants such as lutein and zeaxanthin, which are essential for eye health. These compounds help protect the eyes from damage caused by ultraviolet light and reduce the risk of cataracts and age-related macular degeneration.
– Supports heart health: Although eggs have been debated in the context of cholesterol, they also provide heart-healthy nutrients such as omega-3 fatty acids and folate, which help regulate cholesterol levels and reduce the risk of heart disease.
– Strengthens the immune system: Eggs are rich in vitamins like A, D and E, along with selenium, all of which help strengthen the immune system and protect against infections.
– Helps with weight management: Eggs are satiating and can help reduce calorie intake by keeping you fuller for longer, which can aid in weight management efforts.
