15 Secrets to a Sharper Mind

Why eating red meat may not be such a good idea if you want to stay sharp in your golden years...

For years, doctors have told us eating red meat is great for your brain. After all, the high concentrations of Vitamin B12 you get in red meat helps protect you against senility and brain ageing.
 
Now, it turns out, red meat is a big no-no if you want to steer clear of Alzheimer's… This was highlighted in a new study published in the Journal of Alzheimer's Disease.

Study reveals: Red meat could raise risk of Alzheimer's…

While there's no denying vitamin B is good for your brain, the study showed that Alzheimer's patients have increased levels of iron in the part of the brain responsible for memory. The mineral tends to build-up in excess in the part of the brain damaged in the early stages of the disease.

You may want to limit your red meat and other iron-rich foods such as egg yolks, iron-enriched cereals and grains, oysters, scallops and clams, turkey and chicken giblets, beans, chickpeas and lentils, liver and artichokes. 

But how do you know if your iron levels are too high?

It's easy to get your iron levels checked. All you need to do is a simple blood test called a serum ferritin test.

Once you get your results, scrutinise them carefully. 'The healthy range of serum ferritin lies between 20ng/ml and 80ng/ml. Below 20 is a strong indicator that you're iron deficient, and above 80 suggests you have an iron surplus.

If your iron levels are too high, reduce your iron intake, drink green tea and add phenolic-rich herbs like rosemary to your meals to counteract the surplus.

And since green tea has other Alzheimer's benefits, why not make having a cup part of your daily routine. Green tea reduces the plaque formation implicated in the nerve damage and the memory loss seen in those with Alzheimer's.
