Cadmium Blood Concentrations in Relation to Nutrition

Evaluation of Nutritional Status and Heavy Metals Toxicity for Asthmatic Children

“…There were a negative significant correlation between B-Pb and animal protein intake (r = 0.278, P˂ 0.05). This result are agree with [15] who reported that, the heavy metal levels were decreased by increasing animal food consumption. Also, there were a negative significant correlation between B-Fe and Zn intake (r = 0.289, P˂ 0.05).…”

“…These results may be due to the largest amounts of Cd (75%) are deposited in liver and kidneys, which they cause a hepatotoxicity and nephrotoxicity. The accumulation and toxicity of cadmium in humans depend on various factors, such as the daily intake, the form of cadmium in food and its multiple interaction with dietary components mainly with calcium, zinc, selenium and iron [15].…”

“…Krajčovičová-Kudláčková et al [15] concluded that, the significantly higher mean blood cadmium concentration was measured in vegetarian group when comparison to nonvegetarian group. The highest cadmium content was found in vegan subgroup and that value decreased with increasing animal food consumption (which added dairy products and egg or fish and poultry).…”

Zinc and multi-mineral supplementation should mitigate the pathogenic impact of cadmium exposure

“…However, some food plants are more adept at assimilating soil Cd than others; green leafy vegetables, whole grains (Cd tends to be higher in the bran), tubers, and root vegetables tend to be relatively high in Cd [1] -ironically, this list includes many foods generally recommended for their health-protective potential! Indeed, a study evaluating vegetarians and semi-vegetarians in the Slovak Republic, the highest blood Cd levels were observed in the vegans, with progressively lower Cd levels in those whose diets included higher amounts of animal products [46]. As there is a growing consensus that diets rich in whole plant-derived foods impact health favorably in numerous ways, it does not appear that avoidance of specific foods (other than possibly organ meats and shellfish) will be a prudent strategy for minimizing Cd body burden.…”

“…Other nutraceutical antioxidants, such as astaxanthin, lipoic acid, melatonin, Nacetylcysteine, and phase II inducers, may likewise have potential for mitigating Cd's pathogenic impact [89][90][91][92][93][94][95][96][97][98][99] -though it should be acknowledged that oxidative stress is unlikely to be the only mechanism mediating Cd's adverse effects. The researchers who reported high Cd levels in vegans, also note that whole plant-based foods tend to rich in phytochemical antioxidants which might to some degree offset the toxic impact of Cd [46].…”
