Neuroscientist shares a food that can reduce Alzheimer’s by 43%
A 2024 study published by the Alzheimer’s Association reveals that an estimated 6.9 million Americans aged 65 or older are living with Alzheimer’s dementia. What’s more concerning is that this number could grow to 13.8 million by 2060. Alzheimer’s, which affects numerous Americans every year, is a progressive brain disorder that weakens memory and thinking skills, leading to a loss of the ability to execute simple daily tasks.
Neuroscientist shares food that can reduce Alzheimer’s by half
Robert W.B. Love, a neuroscientist with 1.9M followers on Instagram, who has also been featured on the New York Times, Jimmy Kimmel Live and more, recently shared a video on his social media page. In the video, he revealed one food whose consumption just three times a week can reduce Alzheimer’s by 43%.
What food is it?
“Research published in the Journal of Alzheimer’s by Lei Feng and colleagues out of Singapore found that those who eat this specific food three times a week have a significant reduction in the risk of Alzheimer’s by 43%,” said the neuroscientist in the video. What food is it? It is mushrooms, specifically, Lion’s Mane Mushroom. “This is one of my favourite forms of mushrooms. But the research found that eating all kinds of mushrooms was really beneficial for the brain.”
What kind of mushrooms?
The doc got oyster mushrooms and lion’s mane mushrooms from Whole Foods. He added that every kind of mushroom is good for the brain except white button mushrooms. “Lion’s mane mushroom is actually the absolute best, here’s why.” They improve memory, reduce stress and anxiety, and improve sleep. The doctor thus advised viewers to eat whichever mushrooms they like at least three times a week to reduce the risk of Alzheimer’s disease.
Is this true?
Research conducted to analyse the effects of Lion’s mane mushroom supplementation in patients with mild Alzheimer’s showed a significant improvement in mental state examination. Another study added that the mushrooms may improve the speed of performance and exert a stress reduction effect.
Sleep and brain health
Good sleep is not just about feeling refreshed—it’s essential for brain health. During deep sleep, the brain clears out toxins, consolidates memories, and restores energy for the next day. Experts say poor sleep habits can accelerate cognitive decline and even raise the risk of Alzheimer’s. Lack of quality rest also weakens immunity, impacts mood, and increases stress hormones. Doctors recommend creating a calming bedtime routine, limiting screen use before bed, and keeping a
