Researchers have found that a lifelong diet rich in choline could help protect against Alzheimer’s disease. Choline is an essential nutrient found naturally in some foods and available as a supplement.
It plays a key role in brain function, helping to produce a neurotransmitter called acetylcholine, which is important for memory, muscle control, and mood. It is also used to build cell membranes and regulate genes.
In this study, scientists explored whether choline could reduce Alzheimer’s symptoms. Previous research showed that mice whose mothers had extra choline during pregnancy had better brain health later in life.
The new study took a different approach, focusing on female mice bred to develop Alzheimer’s-like symptoms and testing the effects of choline given throughout their adult lives. This was important because Alzheimer’s is more common in women.
The results were promising. Mice that received a high-choline diet performed better in memory tests compared to those with normal choline levels. A similar study in China found the same benefits in male mice with Alzheimer’s-like symptoms, reinforcing these findings.
The researchers believe choline protects the brain in two ways. First, it helps block the formation of amyloid-beta plaques, which are a major feature of Alzheimer’s disease. Second, it reduces overactivity in microglia—cells responsible for cleaning up waste in the brain.
While microglia help keep the brain healthy, when they become too active, they can cause brain inflammation and lead to nerve cell damage. By keeping microglia in check, choline may help prevent this type of damage.
Since Alzheimer’s disease develops long before symptoms appear, prevention is crucial. Once memory loss and confusion set in, the damage is often irreversible. The researchers hope their findings could lead to new ways to prevent and possibly treat Alzheimer’s. Choline is a safe and widely available nutrient, making it a promising option compared to many experimental drugs.
The next step is clinical trials to see if choline has the same benefits in humans. If proven effective, it could become a simple and affordable way to help protect brain health as people age.
