A growing body of research suggests that dietary copper, found in common vegetables like potatoes and patissons, may play a crucial role in maintaining brain health and reducing the risk of dementia. Professor Weiai Jia from Hebei Medical University (China) explains that copper facilitates iron release, which is essential for oxygen transport to the brain, supporting cognitive function and nervous system regulation (Daily Mail, 2024).
Copper’s Role in Brain Function
Copper is a vital micronutrient involved in:
- Neurotransmitter regulation (affecting memory and learning),
- Energy metabolism in brain cells,
- Protection against oxidative stress, a key factor in neurodegenerative diseases like Alzheimer’s.
According to the NIH (National Institutes of Health), the recommended daily intake of copper for adults is 0.9 mg, slightly lower than Jia’s suggested 1.22 mg, achievable through two medium potatoes or one patisson (NIH, 2023).
The Risks of Excessive Copper Intake
While copper is essential, overconsumption can lead to toxicity, causing symptoms such as:
- Vomiting,
- Hematemesis (blood vomiting),
- Hypotension (dangerously low blood pressure).
The European Food Safety Authority (EFSA) sets an upper limit of 5 mg/day for adults to prevent adverse effects (EFSA, 2022).
Incorporating copper-rich foods like potatoes and patissons into a balanced diet may support cognitive health and reduce dementia risk. However, moderation is key—excessive intake can be harmful. Farmers and agronomists should consider promoting these crops not just for their nutritional value but also for their potential brain-boosting benefits.
