Want to keep your memory as you grow older? Revealed, the 6 foods to boost your brain power

Are you doing what you can to nourish your brain?

Making sure you get as many nutrients as possible helps to optimise your focus, concentration, memory and even intelligence according to daily mail.

Here, Cassandra Barns, a nutritionist reveals the six best foods to boost your brain power.

Oily fish such as salmon are high in omega-3 fatty acids called DHA.

DHA is found in high levels in the grey matter of our brain – proof that we need lots of it for healthy brain function!

Researchers have suggested that having plentiful supplies of DHA supports learning and memory, as well as IQ.

Walking may help protect kidney patients against heart disease, infections

Heart disease and infection are major complications and the leading causes of death in patients with chronic kidney disease. It is now well established that immune system dysfunction is involved in both of these pathological processes. Specifically, impaired immune function predisposes to infection, while persistent immune activation leads to a state of chronic inflammation that can damage the insides of blood vessels and increase heart disease risk. Physical exercise may confer benefits by exerting anti-inflammatory effects and enhancing immunity, but such effects have been largely unexplored in kidney disease.

Drug-resistant bacteria brewing to become a ‘superbug’ for children

As bacteria evolves to fight antibiotics, the most likely to suffer are children with immature immune systems. New evidence that the power of antibiotics is fading fast has been gleaned from a decade-long study of child patients.

Scientists are in a race to develop new medicine to fight antibiotic resistant bacteria as infection rates soar. The Center for Disease Control and Prevention found that infections from P. aeruginosa – relatively common bacteria that can cause skin rashes and ear infections – have grown increasingly antibiotic resistant, according to BBC.

Molecules found on phones reveal lifestyle secrets

Molecules found on mobile phones reveal an astonishing amount about the owner's health and lifestyle - including their food preferences and medication.

Californian scientists found traces of everything from caffeine and spices to skin creams and anti-depressants on 40 phones they tested.

We leave traces of molecules, chemicals and bacteria on everything we touch, according to BBC.

Why wounds heal more slowly with age

Older bodies need longer to mend. Yet until now, researchers have not been able to tease out what age-related changes hinder the body's ability to repair itself.

Recent experiments explored this physiological puzzle by examining molecular changes in aging mouse skin. The results, delineate a new aspect of how the body heals wounds.

"Within days of an injury, skin cells migrate in and close the wound, a process that requires coordination with nearby immune cells. Our experiments have shown that, with aging, disruptions to communication between skin cells and their immune cells slow down this step," says Elaine Fuchs.

"This discovery suggests new approaches to developing treatments that could speed healing among older people," adds Fuchs.
