Dietary copper intake may be linked to Alzheimer's
Conclusion
The findings may point to how copper could contribute to the features of Alzheimer's in mice models of the disease. However, it seems too early to say the link shows a definite cause. It also does not explain how normal levels of copper in our diet could affect the development of Alzheimer's.
It is recommended that caution is applied in interpreting these results. Other metals, such as aluminium, have also been looked at in this way and the results have been similarly inconclusive.
Instead of worrying about exposure to possible environmental factors that we have very little control over, there are other steps that can be taken to reduce the risk of developing dementia:
quitting smoking
avoiding drinking large amounts of alcohol
eating a healthy, balanced diet that includes at least five portions of fruit and vegetables every day
exercising for at least 150 minutes (2 hours and 30 minutes) every week doing moderate-intensity aerobic activity (such as cycling or fast walking), as this will improve both your physical and mental health
making sure your blood pressure is checked and controlled through regular health tests
if you have diabetes, making sure you stick to your diet and take your medication
