Selenium shields your brain against dementia

0 Comments

It’s one thing to have the odd embarrassing senior moment, but repeated memory lapses could signal the early stages of dementia. That’s why awareness is key because diet and lifestyle changes can really make a big impact on the disease’s progression.

According to a new study, eating more selenium-rich eggs may help to protect your brain against dementia-induced damage.

Powerful memory shield

In this latest study, Turkish researchers showed that selenium — a trace element and powerful antioxidant found in eggs, Brazil nuts, salmon, shellfish, and meat — can help shield your brain from brain changes typically associated with dementia.

While doctors and researchers are still trying to figure out exactly what causes dementia, they do know that inflammation and oxidative stress play a role in the development of the disease.

In the study, the researchers divided dementia-induced rats into two groups. One group received selenium and the others a placebo.

By the end of the trial, the rats treated with selenium showed less inflammation and decreased signs of oxidative stress in their blood, compared to the rats who did not receive selenium.

The researchers believe that the “master antioxidant” glutathione plays a key role in protecting your brain from inflammation because if your levels are depleted, you’re more likely to show signs of oxidative stress.

And guess what else selenium was shown to do in this latest study? Increase levels of glutathione.

This antioxidant and anti-inflammatory action is also thought to help prevent certain types of cancer — including liver, breast, prostate, and colon cancer. In addition, glutathione also helps in regulating metabolism and detoxing your body to prevent infection.

You can easily get more selenium in your diet by eating selenium-rich foods like eggs.

Studies show that blood concentrations of selenium decline with age, so you may need an extra boost. If your multivitamin doesn’t include selenium it’s best to check with your doctor first before supplementing with additional selenium, since too much can actually be bad for your body.
