Departments whose administrative spending occurred mainly in the
central Whitehall departments, and were correspondingly less
affected by reclassifications, showed rather smaller proportional changes (11 per cent reduction on average, compared to 32 per cent among the four departments with the largest
administration costs).
For those suffering from lead or other heavy metal poisoning, a protective diet that avoids processed foods and emphasizes the
central components of a nutrient - dense and antioxidant - rich WAPF - style diet is essential (see sidebar).21 Nutritional status shapes susceptibility to lead toxicity in important ways,
affecting lead's intestinal absorption; its mobilization, distribution and retention in the body; and excretion.22 Because oxidative stress is a likely mechanism explaining some of lead's toxic actions, some investigators have begun to explore whether natural antioxidants and trace minerals may help mitigate lead - induced cell damage.17 Specifically, researchers in Spain found that
administration of vitamins A, B6, C and E along with zinc modulated some of the negative effects of lead exposure in rat pups, confirming the influence of nutritional factors on health outcomes following lead exposure.17 Vitamin D also should be a major component of a protective diet.
