•No attempt was made as part of LIDNS to determine the degree of correlation between intake of a nutrient and its level on testing
•This was assessed in other nutritional surveys (see opposite)
•Data presented for males (above) and females (below)
•All data from NDNS except adults 19-64 yrs – vit. B12, from DNSBA
•All correlations were significant (p<0.05) except for vit. D (4-18 yrs) and vit. B12 men 65+ yrs
•The higher the correlation coefficient the more likely that a deficiency could be caused or treated by dietary factors alone
