FEELING GRUMPY - COULD MEAN YOU LACK: Iron.

(RDA): 8.7mg men, 14.8mg women.

Pale skin, light-headedness and spoon-shaped nails are oft-quoted signs of iron deficiency. But feeling cranky (along with tiredness and poor concentration) is a more common early symptom due to reduced levels of oxygen going to the brain, according to the U.S. National Library of Medicine. 

Iron is a key component of red blood cells, and allows them to pick up oxygen and transport it around the body. 

Up to 30 per cent of teenage girls and 17 per cent of women are affected by a low iron status, with risk being higher in women who have heavy periods. 

FOOD SOLUTION: Red meat, nuts and greens - animal sources of iron such as beef, eggs and sardines are absorbed best, but nuts, pulses, green veg and fortified breakfast cereals are also good if taken with a source of vitamin C, e.g. orange juice, to boost absorption. Supplements may be the only solution in more severe deficiency.
