Rosie was asked which are the most dangerous and prevalent vitamin deficiencies.
Rosie said: “The most prevalent deficiency that is most notable is an iron deficiency which leads to anaemia.”
She said there is one major diet and lifestyle change causing the deficiency. “Many people who change their diet and cut out red meat tend to experience this,” she said.
The amount recommended needed daily is 8.7mg a day for men and 14.8mg a day for women.
How to get enough iron
Rosie said: “You can increase your iron-rich foods such as spinach, eggs, beans and nuts.”
Of course, it is also possible to supplement with iron tablets if you are worried and a deficiency.
Those diagnosed with aneamia will be given medication by their doctor.
