Copper plays a role in producing red blood cells and keeping your blood vessels and nerves healthy.
 
It also helps your body absorb iron and supports your immune system function.
 
Without enough copper, you might feel fatigued or notice frequent illnesses, which is why copper-rich foods like walnuts matter.
