Review Meta Analysis
Lowering breakfast glycemic index and glycemic load attenuates postprandial glycemic response: A systematically searched meta-analysis of randomized controlled trials.
Low glycemic index (GI) diets are recommended to reduce the risk for chronic diseases by managing postprandial elevations in blood glucose and insulin. However, to our knowledge, a systematic review of randomized controlled trials (RCTs) to investigate this relationship and interpret its clinical relevance has yet to be performed. This review aims to assess the effect of low versus high GI breakfast meals on postprandial glycemic and insulinemic responses in adults. ⋯ Low GI breakfasts significantly reduced postprandial blood glucose concentrations at all time points: 60 min (WMD: -1.32 mmol/L; 95% CIs, -1.64 to -0.99), 90 min (WMD: -0.74 mmol/L; 95% CI, -0.92 to -0.56), and 120 min (WMD: -0.44 mmol/L; 95% CI, -0.63 to -0.26). Further analyses not only indicated similar trends following the stratification of studies according to the glycemic load, but also showed a more pronounced decline in glycemic response among individuals with metabolic impairments. These results highlight the benefits of lowering breakfast meal GI to provide clinically relevant reductions in acute glucose response.

The aim of this study was to investigate the effects of zinc, vitamin D, and their co-supplementation versus placebo on changes in the Beck Depression Inventory II (BDI-II) score, serum cortisol level, and brain-derived neurotrophic factor (BDNF) in obese/overweight patients with depressive symptoms. ⋯ Supplementation with zinc, vitamin D, or in combination for 12 wk yielded significant beneficial effects on the BDI-II score in obese or overweight patients with BDI-II ≥10.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver morbidity. This condition often is accompanied by obesity, diabetes, and metabolic syndrome (MetS). The aim of this study was to evaluate the connection between lifestyle factors and NAFLD in individuals with MetS. ⋯ Physical activity, adherence to the Mediterranean diet, and consumption of legumes were inversely associated with a non-invasive marker of NAFLD in individuals with MetS. This data can be useful in implementing precision strategies aimed at the prevention, monitoring, and management of NAFLD.

In 2013, the American Medical Association recognized obesity as a disease, of growing scientific, social, and political interest. In 2016 in the United States, prevalence rates of preobesity and obesity exceeded 60%. In Italy, these rates exceeded 40%. ⋯ Obesity has all the criteria to be recognized as a disease. Proper clinical management will lead to cost and complications savings, such as in diabetes. The aim of this review was to discuss in detail the criteria for defining primary obesity as a disease in a step-by-step manner.

Multicenter Study
Changes in the availability of clinical practice guidelines for malnutrition: A 6-y multicenter study.
The aim of the study was to examine the availability of clinical practice guidelines for malnutrition in hospitals over a period of 6 y and the subsequent use of nutritional interventions in malnourished patients. ⋯ The availability of guidelines on malnutrition increased in participating hospitals over the 6-y study period. Regular controls of adherence to the guidelines positively correlated with their availability. More interventions to treat malnutrition were carried out in 2017. The use of clinical practice guidelines in this study was associated with more interventions treating malnutrition.
