These 3 Common Foods Are Actually So Bad For Your Memory, Neuroscientist & MD Warn: ‘Neurotoxic’

1. Alcohol

There are lot of reasons to avoid alcohol—including the effects it has on your brain. "Alcohol is neurotoxic and impairs good sleep," Dr. Helman states emphatically. While occasional consumption might not seem harmful, regular and excessive intake can lead to long-term damage to brain cells. Alcohol's neurotoxic effects can disrupt the communication pathways in the brain, impairing cognitive functions and memory.

Moreover, alcohol severely affects sleep quality, which is crucial for memory consolidation and brain health. Poor sleep can lead to a range of cognitive issues, including difficulty concentrating, forgetfulness, and a higher risk of neurodegenerative diseases.

2. Gluten

As it turns out, there may be more reasons to limit gluten than an allergy. "You want to avoid gluten, which is found in bread and other grains and processed food because gluten promotes inflammation," Dr. Helman advises. Inflammation is a significant risk factor for Alzheimer’s disease.

Gluten, a protein found in wheat, barley, and rye, can trigger inflammatory responses in some individuals, particularly those with gluten sensitivity or celiac disease. Chronic inflammation can damage brain cells and impair cognitive function over time. By reducing or eliminating gluten from your diet, you may decrease inflammation and potentially lower your risk of developing Alzheimer’s and other cognitive impairments.

3. MSG (Monosodium Glutamate)

"MSG is a neuroexcitatory toxin," warns Dr. Helman. Monosodium glutamate, commonly used as a flavor enhancer in many processed foods, can overstimulate neurons to the point of damage or death, a condition known as excitotoxicity. This excessive stimulation can lead to brain cell damage and has been linked to various neurological conditions, including migraines, seizures, and even Alzheimer’s disease. Avoiding foods high in MSG, such as processed snacks, instant noodles, and certain restaurant dishes, can help protect your brain health.

Protecting Your Brain Health

The advice from Dr. Love and Dr. Helman underscores the importance of dietary choices in maintaining brain health and preventing cognitive decline. By being mindful of alcohol, gluten, and MSG intake, you can take proactive steps towards preserving your memory and overall cognitive function. Adopting a brain-healthy diet rich in fruits, vegetables, lean proteins, and whole grains while minimizing neurotoxic and inflammatory foods can significantly impact your long-term brain health.
