Abstract Overweight and obesity are global health problems that affect more than 1.9 billion adults who overweight, of these 600 million obese. In the United States, 60% population. Critical to statistics is association with increased risk cardiovascular disease, type 2 diabetes, metabolic syndrome among other noncommunicable diseases. Many factors, including sugars, have been charged as potential causes. However, overweight their attendant continue increase despite fact there a decline in...

Food is a very common source of toxicant exposure to humans. An unknown number naturally occurring contaminants find their way into food. The most ominous are products mold growth called mycotoxins, which include the carcinogenic aflatoxins. On other hand, more than 2500 chemical substances added foods modify or impart flavor, color, stability, and texture, fortify enrich nutritive value, reduce cost. In addition, an estimated 12,000 used in such that they may unintentionally enter food...

COVID-19, also known as the “novel coronavirus disease 2019,” is a respiratory illness, and causative pathogen officially named “SARS-CoV-2.” Infections with SARS-CoV-2 have now been amplified to global pandemic—as of April 3, 2020, nearly 1 018 000 cases confirmed in more than 195 countries, including 300 within United States. Public safety guidelines are followed worldwide stop spread COVID-19 stay healthy. Despite illness mode invasion through tract, not gastrointestinal an average food...

Severe imbalance in iron metabolism among SARS-CoV-2 infected patients is prominent every symptomatic (mild, moderate to severe) clinical phase of COVID-19. Phase-I - Hypoxia correlates with reduced O2 transport by erythrocytes, overexpression HIF-1α, altered mitochondrial bioenergetics host metabolic reprogramming (HMR). Phase-II Hyperferritinemia results from an increased overload, which triggers a fulminant proinflammatory response the acute cytokine release syndrome (CRS). Elevated...

In May 2012, an oats workshop was held in New York to convene a group of international experts discuss the implications and applications relative human health. These diverse represented disciplines including, but not limited to, epidemiology, food regulation, nutrition science, grain breeding plant genetics, processing, medicine public-health policy. This ensuing series addresses three important aspects pertinent oats: brief overview dynamics oats; spectrum established emerging research...

A large body of clinical evidence suggests that the consumption 3 g or more per d β-glucan from oats barley, as part a diet low in saturated fat and cholesterol, may reduce risk CHD. The unique chemical physical properties physiological responses to oat contribute their demonstrated health benefits; other attributes are still under evaluation. Many these benefits, such those associated with reduced CVD, codified claims by several regulatory agencies, Food Drug Administration USA European...

As the COVID-19 pandemic intensified global health crisis, containment of SARS-CoV-2 infection in pregnancies, and inherent risk vertical transmission virus from mother-to-fetus (or neonate) poses a major concern. Most COVID-19-Pregnancy patients showed mild to moderate pneumonia with no pregnancy loss congenital virus; however, an increase hypoxia-induced preterm deliveries was apparent. Also, breastmilk several mothers tested negative for virus. Taken together, natural barrier function...
