July Advances in Nutritrion from Roc Nutrition Investigator

Happy Labor Day.  Good time to regenerate your brain through healthy nutrition, directions sent previously here. Here are other notes from Advances in Nutrition July 2012.

Cardiometabolic disease, comprising cardiovascular diseases, type 2 diabetes, and their associated risk factors including metabolic syndrome and obesity, is the leading cause of death worldwide. Plant foods are rich sources of different groups of bioactive compounds, which might not be essential throughout life but promote health and well-being by reducing the risk of age-related chronic diseases. Most important may be quercetin (in blueberries), EGCG (in green tea), cocoa (in dark chocolate), polyphenols, caffeine and plant sterols, and the identified potential determinants involved.  Reading this article may help you realize how valuable these foods are to heart health.

The Impact of the Mediterranean Diet on the Cognitive Functioning of Healthy Older Adults: A Systematic Review and Meta-Analysis. The strongest evidence suggests a beneficial effect of the Mediterranean Diet on older adults’ global cognition.

Current Evidence on Associations of Nutritional Factors with Ovarian Reserve and Timing of Menopause: A Systematic Review. Ovarian aging is thought to be influenced by environmental factors, including nutrition. Significant associations with ovarian reserve markers were found in 4 of 7 studies on serum 25(OH)D, 2 of 6 studies on soy or soy products, 1 of 2 studies on fiber intake, 1 study on serum zinc and copper concentrations, and 1 study on serum antioxidant concentrations.

Dietary Guidelines for Breast Cancer Patients: A Critical Review. A conservative energy restriction of 500–1000 kcal/d could be considered in the dietary intervention when appropriate. Garlic and cruciferous vegetables must also be part of the nutrition therapy. Adequate dietary intakes of food-based macro- and micronutrients rich in β-carotene and vitamins A, E, and C can both prevent deterioration in BCPs’ nutritional status and improve their overall health and prognosis.

JUST FOR DOCTORS: Energy, Protein, Carbohydrate, and Lipid Intakes and Their Effects on Morbidity and Mortality in Critically Ill Adult Patients: A Systematic Review. Enteral nutrition (EN) is generally recommended over parenteral nutrition (PN) and is beneficial when administered within 24–48 h after ICU admission. In contrast, early PN does not provide substantial advantages in terms of morbidity and mortality, and the time when it is safe and beneficial remains unclear. The most advantageous recommendation seems to be administration of a hypocaloric (<20 kcal · kg–1 · d–1), high-protein diet (amino acids at doses of ≥2 g · kg–1 · d–1), at least during the first week of critical illness. Another important factor for reducing morbidity is the maintenance of blood glucose concentrations at 120–150 mg/dL, which is accomplished with the use of insulin and lower doses of glucose of 1–2 g · kg–1 · d–1, because this prevents the risk of hypoglycemia and is associated with a better prognosis according to recent studies.
