Assessment of Carbohydrate Availability, Fermentability, and Food Energy Value in Humans Using Measurements of Breath Hydrogen
Livesey G
Measurements in humans of their breath hydrogen is sometimes used to assess the availability, fermentability, and food energy value of carbohydrates that, to an unknown extent, resists small intestinal digestion and fermentation in the large intestine. Here I outline that the method is utterly flawed and conclude that it is unsuitable for making claims as to the availability, fermentability, and food energy value of carbohydrates. More traditional methods, although more demanding of time and effort, can be used. Otherwise further development of methodology is essential to avoid undue risk of bias.

The Fat-to-Lean Mass Ratio Is Associated with Hyperinsulinemia in Healthy Mexican Adolescents
Gamboa-Gómez CI, Guerrero-Romero F, Aradillas-García C, Rodríguez-Morán M and Simental-Mendía LE
To evaluate whether the Fat-to-Lean Mass (FyM) ratio is associated to hyperinsulinemia in healthy adolescents. Apparently healthy adolescents aged 10 to 15 years that according to sex, age, and percentiles of body fat percent, were included and allocated into the groups with elevated (body fat percent ≥85 percentile) and normal total body fat (body fat percent <85 percentile). The FyM ratio was calculated as total lean mass (kg)/total body fat (kg) and hyperinsulinemia was defined by fasting insulin levels ≥20 µUI/mL. A total of 1,299 adolescents, 665 (51.9%) girls and 634 (48.1%) boys, were enrolled and allocated into the groups with high (n = 439) and normal (n = 860) body fat. The FyM index remained significantly associated with hyperinsulinemia (OR 5.58; CI: 1.54-28.10) after logistic regression analysis adjusted by sex, age, body-weight, body mass index, and waist circumference. The FyM index is highly associated to the presence of hyperinsulinemia in adolescents, emerging as a useful tool from anthropometric measurements for identify insulin abnormalities.

Magnesium and COVID-19 - Some Further Comments - A Commentary on Combating COVID-19 and Building Immune Resilience: A Potential Role for Magnesium Nutrition? J Am Coll Nutr. 2020;1-9. doi:10.1080/07315724.2020.1785971. Cited in: PMID: 32649272
Micke O, Vormann J and Kisters K
The paper "Combating COVID-19 and Building Immune Resilience: A Potential Role for Magnesium Nutrition?" by TC Wallace, which was published in the Journal of the American College of Nutrition highlights the importance of adequate magnesium (Mg) supply in relation to COVID-19. Wallace notes that Mg deficiency is associated with low-grade chronic inflammation. Furthermore, hypokalemia and a lack of active Vitamin D are consequences of a Mg deficit. In this way, Mg deficiency may exacerbate the course of COVID-19. Therefore, in patients with Covid-19 permanent monitoring of the Mg status and, if necessary, supplementation should be carried out. The possible importance of Mg in COVID-19 was only recently discussed also by Iotti et al. and the German Society for Magnesium Research e.V. Considering the meaningful connections between Mg and COVID-19 there are relevant research topics that should be addressed: Does Mg deficiency increase the risk of infection with COVID-19 or the risk of a severe course of the disease? Is there an increased prevalence of Mg deficiency in COVID-19 patients? Could Mg supplementation alleviate the course of the disease in COVID-19 or reduce complications? Does pharmacological induction of hypermagnesemia via intravenous Mg provide clinical benefits for COVID-19 patients in the intensive care unit (for example with regard to lung function or thromboembolism)?
COVID-19 Infection Pandemic: From the Frontline in Italy
Gastaldelli A, Gastaldelli M and Bastianoni S
The infection caused by COVID-19 (i.e. corona virus disease 2019) has caused more than 5.2 million cases and more than 337,000 deaths worldwide. Italy was the European epicenter for virus spread and one with most cases and deaths. The first Italian patient was diagnosed on February 18, a young man hospitalized in Lombardy (Northern Italy). The Italian government not only isolated the village where he lived, but a few days later put the entire country in lockdown. We have here analyzed the COVID-19 Italian data during the first three months after the outbreak and the effect of lockdown. COVID-19 virus has a high transmission rate and is associated with high fatality rate especially in the older population. The initial reproduction rate of the virus (R0) in Italy was between 2.1 and 3.3 in different Italian regions, with a doubling time between 2.7 and 3.2 days. The number of confirmed cases has now reached 229,000 but after the lockdown R0 is finally below 1. Despite the lockdown, the number of infected and deceased patients in Italy was very high, with a lethality rate higher than in other countries. It is likely that number of cases is underestimating the real since the number of asymptomatic and paucisymptomatic is relatively high. It is important to investigate which patients are more vulnerable and also if other co-factors can account for this high fatality rate, since this pandemia is far from being resolved.

Nascimento-Souza MA, Paiva PG, Silva AD, Duarte MSL and Ribeiro AQ
The dietary total antioxidant capacity (TAC) has been proposed as a suitable tool to estimate the dietary antioxidant intake. However, the main foods/groups that contribute to the dietary TAC of older adults are poorly studied. We aimed to estimate the dietary TAC and to identify the main foods/groups that contribute to the dietary TAC of older adults in a medium-sized Brazilian city.
Renal and Hepatic Disease: as Diet Therapy Proposal for Prevention and Treatment
Manzanilla Valdez ML and Segura Campos MR
The lack of prevention of noncommunicable diseases (NCDs) has caused an increase in the mortality rate including conditions such as chronic kidney disease (CKD) and liver disease (LD). The high complexity of CKD and LD results in alterations in the metabolism of carbohydrates, proteins, and lipids. One of the changes observed in CKD and LD is the decrease in albumin, elevation of PO, K, creatinine, urea, and transaminase enzymes. The pharmacological treatment is expensive. Nowadays, phytotherapy is an option to treat NCDs. Aqueous, ethanolic, methanolic, and ethyl acetate extracts of have shown nephroprotective and hepatoprotective potential and can be an alternative to prevent and treat CKD and LD. , known as Chaya by Mayas in Yucatán, is a shrub that is consumed in Mexico and in the world, has a low cost, it is very accessible, and can growth in extreme weather. The aim of this review is to show the potential biological effects of extracts, and the association of the phytochemicals in the extract. It is known that different solvents result in the uptake of different phytochemicals. These have shown various effects such as hypoglycemic, hypotensive, hypolipidemic, and antioxidant, being a natural alternative to the treatment of NCDs.Key teaching pointsPhytotherapy is a proposal to treat NCDs. extracts have a hypotensive effect. extracts reduce blood sugar in diabetic rats.Chaya extracts are no toxic for renal and hepatic cells.

Analyzing Blood Pressure Ascent during Aging in Non-Diabetics: Focusing on Links to Insulin Resistance and Body Fat Mass
Preuss HG, Kaats GR, Mrvichin N and Bagchi D
A gradual upward progression of blood pressure (BP) occurs regularly in most humans during aging. This is unfortunate, because it is generally recognized that elevation of BP, even when relatively mild, is eventually detrimental to human health. Accordingly, considerably more understanding of the pathophysiology behind such a phenomenon is important in order to institute the correct remedies. Two components of the ubiquitous metabolic syndrome (MS) with nutritional implications, elevated insulin resistance (IR) and excess body fat mass (FM), are often postulated to be critical driving forces behind the elevated BP that is common with aging. The current study, therefore, focuses on the presence and importance of IR and/or body FM in BP regulation of non-diabetics over the lifespan.
Personalized Nutrition 2020: Proceedings from the American Nutrition Association's 61st Annual Summit
Behm VAY and Bush CL
The American Nutrition Association's 61st annual summit, Personalized Nutrition 2020, convened thought leaders and stakeholders to discuss innovations in personalized nutrition (PN) technology, science, and practice. Evolutions in PN science and technology are enabling novel inroads and applications, leading the ANA to launch a new component of its annual gathering, the Personalized Nutrition Business Leaders Forum. In light of renewed global interest in immune health during the COVID-19 pandemic, the flagship Science and Practice Conference focused on the topic of immune resilience. Presentations highlighted emerging research suggesting that individuals may have unique immunological responses to exogenous insults and that immune system resilience can be optimized by the application of nutritional factors that regulate immune function. Thus, PN tools and services may uniquely enhance immune preparedness by optimizing immune system function and status. Furthermore, PN practitioners trained to utilize emerging techniques and services can help prepare society to meet our modern immune challenges.HighlightsIn order to be effectively implemented, personalized nutrition requires ongoing research, innovative tools and services, and a specialized health care workforcePersonalized nutrition will continue to grow as an economic driver as consumer and patient interest surgeThere has been increased interest in the role of nutrition in immune function in light of COVID-19 and its comorbidities.
l-Cysteine Stimulates the Effect of Vitamin D on Inhibition of Oxidative Stress, IL-8, and MCP-1 Secretion in High Glucose Treated Monocytes
Jain SK, Micinski D and Parsanathan R
Vitamin D deficiency is common in the general population and diabetic patients, and supplementation with vitamin D is widely used to help lower oxidative stress and inflammation. The cytokine storm in SARS-CoV2 infection has been linked with both diabetes and Vitamin D deficiency. This study examined the hypothesis that supplementation with vitamin D, in combination with l-cysteine (LC), is better at reducing oxidative stress and thereby, more effective, at inhibiting the secretion of the pro-inflammatory cytokines, Interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) in U937 monocytes exposed to high glucose concentrations. U937 monocytes were pretreated with 1,25 (OH) vitamin D (VD, 10 nM) or LC (250 µM) or VD + LC for 24 h and then exposed to control or high glucose (HG, 25 mM) for another 24 h. There were significantly greater reactive oxygen species (ROS) levels in monocytes treated with HG than those in controls. Combined supplementation with VD and LC showed a more significant reduction in ROS (46%) in comparison with treatment with LC (19%) or VD (26%) alone in monocytes exposed to HG. Similarly, VD supplementation, together with LC, caused a more significant inhibition in the secretion of IL-8 (36% versus 16%) and MCP-1 (46% versus 26%) in comparison with that of VD (10 nM) alone in high-glucose treated monocytes. These results suggest that combined supplementation with vitamin D and LC has the potential to be more effective than either VD or LC alone in lowering the risk of oxidative stress and inflammation associated with type 2 diabetes or COVID-19 infection. Further, this combined vitamin D with LC/N-acetylcysteine may be a potent alternative therapy for SARS-CoV2 infected subjects. This approach can prevent cellular damage due to cytokine storm in comorbid systemic inflammatory conditions, such as diabetes, obesity, and hypertension.
