From the Guidelines
Eggs do not significantly contribute to dementia risk when consumed in moderation, and they can be part of a balanced diet that supports brain health. The current evidence does not strongly support a link between egg consumption and dementia risk. Eggs contain nutrients like choline, lutein, and zeaxanthin, which are beneficial for brain health and cognitive function 1. While eggs do contain cholesterol, research has shown that dietary cholesterol has less impact on blood cholesterol levels than previously thought. A Mediterranean-type diet, which includes moderate amounts of dairy products, low meat, and regular fish intake, seems to support maintenance of cognitive function and reduce the risk of cognitive decline in healthy older persons 1. Some key points to consider:
- Eggs can be part of a balanced diet that supports brain health when consumed alongside plenty of vegetables, fruits, whole grains, and healthy fats from sources like olive oil, nuts, and fatty fish.
- Individuals with specific conditions like cardiovascular disease, diabetes, or those genetically predisposed to higher cholesterol absorption might need to be more cautious with egg consumption.
- Providing adequate food according to individual needs, with respect to personal preferences, is a basic prerequisite for adequate dietary intake in all stages of dementia 1.
- A diet rich in fruits, vegetables, legumes, and unrefined cereals, with moderate amounts of dairy products, low meat, and regular fish intake, seems to deliver all nutrients in adequate amounts to support maintenance of cognitive function and reduce the risk of cognitive decline in healthy older persons 1.
From the Research
Egg Consumption and Dementia Risk
- There is no direct evidence in the provided studies that links egg consumption to an increased risk of dementia 2, 3, 4.
- However, some studies suggest that certain nutrients found in eggs, such as choline, may have a role in protecting against chronic diseases, including cognitive decline 2.
- Omega-3 fatty acids, which are not typically found in high amounts in eggs, have been shown to have a potential benefit in reducing the risk of cognitive decline and dementia 5, 6.
- The relationship between dietary cholesterol, found in eggs, and cognitive function is not well understood, but some studies suggest that it may not have a significant impact on dementia risk 3, 4.
- More research is needed to fully understand the relationship between egg consumption and dementia risk, as well as the potential benefits and risks of egg intake for individuals with different nutritional needs and health status 2, 3, 4.
