“…The mean concentration of Cd in this study was 0.0085 mg/ kg. Milk and dairy products were the lowest Pb contaminated foods in Jiangsu Province in 2014; the mean concentration was 0.036 mg/ kg (Jin et al, 2014), which was higher than the average Pb content (0.0189 mg/kg) in all foodstuffs found in this study. The highest content of As in this study was cod, with a mean concentration of 1.403 mg/kg.…”

“…Sun et al [50] estimated the dietary intake of lead in Jiangsu Province using the diary study method and found a mean intake of 2.75 μg/kg bw/day for children aged 2–6 years and 1.55 μg/kg bw/day for the general population. Jin et al [44] re-estimated the dietary lead exposure in Jiangsu using new contaminant surveillance data, and their results indicated a dietary lead intake of 3.019 μg/kg bw/day in children aged 2–6 years and 1.742 μg/kg bw/day in the general population. Fan et al [51] reported dietary lead exposure values for children aged 2–6 years and for the general population in Shaoxing of 1.87 and 1.14 μg/kg bw/day, respectively.…”

“…A dietary lead exposure assessment in the Chinese population conducted by Li et al yielded MOE values of 0.1 for those aged 2–12 years, 0.7 for those aged 13–19 years, and 0.7–0.9 for those at least 20 years of age [34]. For the residents of Jiangsu province, the MOE values for the mean lead exposure were found to be 0.272 for those aged 2–6 years and 1.031 for those aged 18–80 years [44]. The MOE values of dietary lead exposure in Shaoxing were found to be 0.32–0.35 for those aged 2–6 years, 0.49–0.59 for those aged 7–17 years, and 1.3–1.7 for those aged ≥18 years [51].…”

Lead exposure is associated with a wide range of adverse effects on human health. The principal exposure route in the general population is through the diet. In this study, we estimate the dietary lead intake and associated health risks among the residents of Guangzhou, China. Data on lead concentrations were derived from the food safety risk monitoring system, which included 6339 samples from 27 food categories collected in 2014–2017. Food consumption data were taken from a 2011 dietary survey of 2960 Guangzhou residents from 998 households. Dietary lead intake was estimated by age group (3–6, 7–17, 18–59, and ≥60 years), and relevant health risks were assessed using the margin of exposure (MOE) method. The mean and 95th percentiles (P95) of dietary lead intake were respectively 0.7466 and 2.4525 μg/kg body weight per day for preschool children aged 3–6 years; 0.4739 and 1.5522 μg/kg bw/day for school children aged 7–17 years; 0.3759 and 1.1832 μg/kg bw/day for adults aged 18–59 years; and 0.4031 and 1.3589 μg/kg bw/day for adults aged ≥60 years. The MOE value was less than 1 for preschool children at the mean exposure level and for all age groups at the P95 exposure level. Rice and its products, leafy vegetables, and wheat flour and its products were found to be the primary food sources of lead exposure. Our findings suggest that the health risk from dietary lead exposure is low for Guangzhou residents overall, but that young children and consumers of certain foods may be at increased risk. Continued efforts are needed to reduce the dietary lead exposure in Guangzhou.

“…Among young children living in the US and Mexico, lead concentration in candy was associated with BLLs. 56,57 Others have also found the potential for lead exposure from foods, including vegetables and cereals, [58][59][60] with some home-grown vegetables, particularly from urban gardens, being one possible source of exposure. 61 The Food and Agriculture Organization of the United Nations/ World Health Organization guidance on food-based lead exposure, set at a provisional tolerable monthly intake of 25 mg/ kg body weight, is now considered inadequate to protect human health.…”

The “Lead Diet”: Can Dietary Approaches Prevent or Treat Lead Exposure?

lthough blood lead levels (BLLs) have been declining in the US for decades, pediatric lead exposure is an ongoing public health issue. 1 Given the welldocumented cognitive deficits at BLLs <10 mg/ dL, in 2012 the Centers for Disease Control and Prevention (CDC) called for renewed efforts for the primary prevention of any lead exposure in children. 2 Recent events in Flint, Michigan, also have served to refocus the public and health professionals on the seriousness of lead exposure. According to CDC statistics for years 2010-2014, 0.5%-0.6% of children (13 000-26 000) had confirmed BLLs ≥10 mg/dL and 4%-6% (106 000-282 000) ≥5 mg/dL. 3 Only 10%-18% of all children in the US aged <6 years, however, had a BLL test during that period. A recent study based on a national clinical laboratory database reported an overall prevalence of BLLs ≥10 mg/dL at 0.58% and ≥5 mg/dL at 2.95% for the years 2009-2015, with certain US states and cities particularly affected. 4 Whether through contaminated water, lead-based paint, or a combination of sources, the problem of lead exposure resurfaces periodically in US municipalities like Flint, Michigan, Washington, DC, or Buffalo, New York, 5-7 highlighting issues of aging infrastructures, under-resourced communities, poor decision making, and environmental injustice. Overlaid on these systemic causes are personal poverty and complex family situations, potentially creating multiple threats to optimal child health and development, including factors such as poor diet or low developmental stimulation. Parents and frontline health workers often are left to figure out how to help affected children, posing questions regarding effective interventions. Because dietary approaches seem relatively easy to implement compared with, for example, lead abatement or replacing old plumbing infrastructure, the conversation often turns to dietary recommendations. The 2012 CDC report highlights the role of pediatricians in educating families on nutrition as one primary prevention approach. 2 It should be emphasized that the prevention of lead exposure among vulnerable populations is the best solution to this problem and that intervening in exposure via dietary approaches does not address the root cause. Furthermore, careful examination of the links between nutrition (nutritional status, nutrients, diet) and lead exposure reveals limited and tenuous evidence.
