Abstract
Lead is a pervasive toxin that has been implicated in human poisonings throughout history. Exposure mitigation strategies in the United States and worldwide have led to a decline in symptomatic poisonings and population blood lead levels; however, lead remains a major health hazard. In this article, we review the history of lead toxicity, clinical manifestations ranging from subclinical and subtle features to life-threatening complications, and the subsequent public health interventions in the US. In addition, we explore common routes of lead exposure and the unique differences between the US and Iran. Although the US has made significant strides with regard to this public health issue, lead poisoning in both countries continues to be a health hazard in the adult and pediatric populations. It is also critical to consider natural disasters and reconstruction efforts as potential sources of lead contamination. In conclusion, we make recommendations that both the US and Iranian authorities can implement to eradicate lead as a public health hazard.

Obesity has reached epidemic proportions and is still escalating at an alarming rate worldwide
Obesity is associated with chronic activation of low-grade inflammation [3], which is implicated in the pathogenesis of obesity-associated diseases including insulin resistance, type-2 diabetes (T2D) [4, 5] and cardiovascular disease [6, 7]
A numerous of studies has been shown that shortchain fatty acids (SCFAs) inhibit inflammation with focus on butyrate and to a lesser extent on acetate and Propionic Acid (PA), [16]
Summary
Obesity has reached epidemic proportions and is still escalating at an alarming rate worldwide. In Palestine the prevalence of obesity has been shown to be approximately 4. The etiology of obesity and low-grade inflammation is complex and involves intrinsic and extrinsic factors. The colonization of germ-free mice with microbiota derived from obese mice results in significantly greater adiposity than colonization with microbiota from lean mice [12]. Prebiotic diets such as fructans [13] are associated with general better health, including the decrease in body weight, fat mass and the severity of T2D [14,15,16]. The factors that influence the composition and metabolism of intestinal
