A new study from Loma Linda University in California has revealed that adding eggs to your diet might lower the risk of developing Alzheimer’s. This disease is a gradual neurodegenerative condition and is the sixth leading cause of death in the U.S.
According to the Alzheimer’s Association, by 2026, approximately one in nine Americans aged 65 and older will be diagnosed, making it a leading cause of dementia.
The findings indicate that consuming eggs as little as twice a week can significantly reduce Alzheimer’s risk. In fact, eggs are packed with essential nutrients like vitamin B12 and phospholipids, which are known to support brain health.
- Eating eggs just twice weekly significantly impacts Alzheimer’s risk.
- Eggs contain key nutrients that help preserve brain tissue.
- Findings could aid in preventing or delaying dementia, affecting around 200,000 Americans aged 30-64.
The study suggests that the nutrients in eggs may provide neuroprotective advantages when included in a balanced diet.
Research Indicates Lower Risk with Egg Consumption
The study determined that eating eggs twice a week can reduce the risk of Alzheimer’s by 20%. Interestingly, the risk further declines by over 25% if eggs are consumed five times a week or more.
In this research, scientists monitored 40,000 participants over a period of 15 years. Those who ate eggs infrequently—only once or twice a month—showed a 17% lower likelihood of developing severe dementia compared to non-consumers. For those who consumed eggs four to five times weekly, the percentage rose to 27%.
“Moderate egg consumption was directly linked to a lower risk of Alzheimer’s, even with adjustments for dietary habits, demographics, lifestyle factors, and other health issues,” the study reported.
While there are concerns regarding cholesterol levels from eating eggs, the American Heart Association has noted that adults can safely eat up to one egg a day, or seven weekly.
Eggs Are Nutritional Powerhouses
Eggs can play a crucial role in combating Alzheimer’s due to their richness in vital nutrients, particularly vitamin B12. A deficiency in this vitamin can increase homocysteine levels, a known risk factor for Alzheimer’s. Moreover, dietary adjustments can help in maintaining normal bodily functions.
Each egg yolk provides about 25% of the daily recommended intake of vitamin B12. Besides, egg yolks are also high in phospholipids necessary for proper neurotransmitter function.
Other significant nutrients in eggs include high-quality proteins that are rich in tryptophan—a precursor to serotonin, which plays an essential role in mood and cognition. The study also pointed out the presence of docosahexaenoic acid, an omega-3 fatty acid essential for brain cell function and health.
Eggs also provide choline and DHA, both essential for brain health, as they contribute to memory and cognitive functions. Nutrients like lutein and zeaxanthin, found in eggs, may improve cognitive performance and combat oxidative stress.
It’s vital to identify modifiable lifestyle factors such as diet, especially since Alzheimer’s disease can develop nearly two decades before symptoms appear.
Rising Numbers of Alzheimer’s Cases
An estimated 7.4 million Americans 65 and older are living with Alzheimer’s, according to data from the 2026 Alzheimer’s Organization survey, with a majority over the age of 75. The rate of Alzheimer’s cases among those younger than 65 is also increasing steadily.
Researchers estimate that around 200,000 Americans between the ages of 30 and 64 have younger-onset dementia.
Globally, the incidence of young-onset dementia has surged by over 200% from 1990 to 2021, highlighting a significant rise in those affected.
While no definitive prevention or cure exists currently, early detection of warning signs is crucial. These signs can include memory lapses, difficulties with familiar tasks, or challenges with spoken or written language.
Public Reactions to Findings
On social media, reactions to the study’s findings have been mixed, with some users expressing surprise about the health implications of eggs, pointing out past advice that eggs were harmful.
