An Egg a Day Lowers Alzheimer's Risk

An egg a day can noticeably mitigate the path to Alzheimer's according to recent studies.

In the journal "The Journal of Nutrition," US scientists reported after several years of observing 1,024 participants (average age 81.4 years) that the daily consumption of at least one egg can significantly reduce the risk of developing Alzheimer's dementia.

Always in the fridge: The nutrient-rich egg yolk contains a combination of omega-3 fatty acids, lutein, and especially choline – a vitamin-like substance that acts as a neurotransmitter and is crucial for the brain and nervous system. With about 150 mg of choline, an egg already provides around 25 percent of the daily requirement.

Why Choline is So Important

Choline plays a central role in signal transmission in the brain and supports muscle control. Researchers led by Dr. Taylor Wallace therefore see choline as a key element in cognitive development and in maintaining mental performance in old age.

Proven Effect, But Still Open Questions

The US study suggests a risk reduction of up to 47 percent with regular egg consumption. Nevertheless, the scientists emphasize that further research is needed to prove direct cause-and-effect relationships.

Consider Cholesterol – Moderation is Key

A common objection: Eggs contain cholesterol, which can increase LDL levels – and could in turn be a risk factor for dementia. Therefore, experts recommend balanced consumption and an overall healthy diet.

Questions and Answers on Eggs and Dementia Prevention

How many eggs per week reduce the risk of dementia?

In the US study, the daily consumption of just one egg led to a significant reduction in Alzheimer's risk. Participants who consumed one or more eggs per week showed up to a 47 percent lower risk.

Why is choline in egg yolk so important?

Choline supports neurotransmitters and is essential for memory and nervous system functions. It is particularly concentrated in eggs – about 150 mg per egg – covering a quarter of the daily requirement.

What other foods also contain a lot of choline?

Besides eggs, beef liver, fish such as salmon and cod, chicken, soybeans, and wheat germ are good sources of choline. For vegetarians and vegans, soy products, broccoli, or quinoa are suitable alternatives, although the choline amounts are lower.

Is choline intake through supplements also advisable?

Choline supplements can be useful if the daily requirement is not met through diet – especially for certain risk groups or vegan diets. Consultation with medical professionals is recommended, as overdoses can cause side effects such as sweating or blood pressure fluctuations.

At what age should one pay attention to a choline-rich diet?

Even at a young age, a choline-rich diet contributes to cognitive development. However, it becomes particularly relevant from middle age, around 40 years, when the first age-related changes in the brain begin. A preventive effect unfolds through long-term, continuous supply.

Can choline also help with existing dementia conditions?

Most studies examine the preventive effect of choline. Indications of a possible alleviation of cognitive symptoms in already diagnosed dementia are not yet clearly proven. It is more of a preventive measure, not a therapeutic treatment.
