Epidemiologic studies evaluating the association between the intake of vegetables and fruit and the risk for glioma have produced inconsistent results. Therefore, the aim of this study was to test the hypothesis that higher vegetable and fruit intake may have a protective effect on risk for glioma. ⋯ This analysis indicated that intake of vegetables might have a protective effect on glioma. The intake of fruit might have a protective effect on glioma in the Asian population; however, the results need to be confirmed.

Review
Perioperative nutritional support of patients undergoing pancreatic surgery in the age of ERAS.
The results achieved through the Enhanced Recovery After Surgery (ERAS) approach in gastrointestinal surgery have led to its enthusiastic acceptance in pancreatic surgery. However, the ERAS program also involves an early oral feeding that is not always feasible after pancreatoduodenectomy. The aim of this review was to investigate in the literature whether the difficulty with early oral feeding in these patients was adequately balanced by perioperative enteral or parenteral nutritional support as recommended by the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines or whether these recommendations have lost value in the "bundle" of the ERAS. ⋯ The current practice of the ERAS program in these patients appears to neglect some ESPEN recommendations. On the other hand, both ESPEN and ERAS recommendations could be combined for a supplemental benefit for the patient.

Randomized Controlled Trial
Dietary fatty acids intake and mortality in patients with heart failure.
Dietary strategies in heart failure (HF) are focused on sodium and fluid restriction to minimize the risk for acute volume overload episodes. However, the importance of dietary factors beyond sodium intake in the prognosis of the disease is uncertain. The purpose of this study was to evaluate the association of macro- and micronutrients intake on 1-y mortality in patients with HF. ⋯ Intake of PUFAs and SFAs was independently associated with 1-y all-cause mortality in patients with chronic HF. Limiting dietary SFA and increasing PUFA intake may be advisable in this population.

Randomized Controlled Trial
A meal replacement regimen improves blood glucose levels in prediabetic healthy individuals with impaired fasting glucose.
The aim of this study was to investigate the effect of a 6-wk intervention with either lifestyle intervention (increased physical activity and a low-calorie diet) or a meal replacement regimen on glycemic control in patients who are prediabetic and have impaired fasting glucose. ⋯ Both interventions resulted in a significant decrease in body weight and BMI, although the reduction was more pronounced (P < 0.05) in the MR group. In both groups, glucose concentrations decreased significantly (LS: -12 mg/dL, P < 0.01; MR: -11 mg/dL, P < 0.01), and mean glucose levels returned to the normal range. Insulin (LS: -1 μU/mg [not significant]; MR: -6.3 μU/mg, P < 0.01) and homeostasis model assessment of insulin resistance (HOMA-IR; LS -0.92, P < 0.01; MR: -2.1, P < 0.01) were also significantly lower following both interventions; again improvements were more pronounced in the MR group (insulin: P < 0.05; HOMA P < 0.01) CONCLUSION: It can be concluded that meal replacement is an effective intervention for rapid improvement of elevated fasting glucose and increased insulin concentrations, these being important biomarkers of the prediabetic state. The 6-wk intervention has shown that the effect of meal replacement on fasting blood glucose was comparable to the effect of lifestyle intervention. The alterations in BMI, insulin, and HOMA-IR were significantly more pronounced following the meal replacement regimen.

The aim of this study was to estimate the intake of known individual polyphenols and their major dietary sources in the Polish arm of the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study. ⋯ The current study provides the most updated data for individual polyphenols intake in the diet of a well-established nutritional cohort. These findings will be useful to assess potential beneficial role on health of specific foods with high polyphenol content and characterize the effects of individual phenolic compounds.
