There is substantial evidence to show that consumption and increased blood levels of the very long-chain (VLC) ω-3 polyunsaturated fatty acids (ω-3 PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are associated with health benefits. The consumption of oily fish is an effective way of increasing EPA and DHA intake and status, but intake in most Western countries remains below the levels recommended for optimal health. The reasons for this include not liking the taste, a concern about sustainability of fish supplies, or potential chemical and heavy metal contamination. ⋯ Oil crops naturally rich in SDA or enriched through genetic modification may offer an alternative supplemental oil to boost the population status of VLC ω-3 PUFAs. This review discusses the currently available evidence that increased SDA consumption can increase red blood cell EPA content, although this is less than the effect of supplementation directly with EPA. There is now a need for trials specifically designed to assess whether an increased SDA consumption would translate into improved human health outcomes.

To estimate the nutritional risk in children 2 to 6 y old. ⋯ The prevalence of inadequate dietary intake was low for most nutrients. However, fiber, calcium, and vitamin D and E intakes were lower than recommended. Moreover, children consumed large amounts of sodium and saturated fat.

The Nutritional Risk Screening-2002 (NRS-2000) is currently recommended by the European Society of Parenteral and Enteral Nutrition as a screening tool in hospitalized patients. However, for preoperative risk prediction, the usefulness of this tool is uncertain and may depend on the type of surgical disease. The present study investigated the relative prognostic importance of the NRS-2002 and of established medical and surgical predictors for postoperative complications in patients scheduled for non-abdominal procedures. ⋯ In surgical patients with non-abdominal diseases, a modified NRS-2002 classification may be required to preoperatively identify patients at a high nutritional risk. The NRS-2002 alone is insufficient to precisely predict complications.

Dietary treatment is important for the management of Parkinson's disease (PD). Our objective was to describe the dietary habits and assess the nutritional status of Ghanaian patients with PD. This study is part of a larger project, for which Ghana has been selected as a pilot country. ⋯ This study has yielded information that could be useful for the study of the management of PD and for the assessment of response to therapy.

To investigate the effect of different dietary oils on the main hepatic enzymes involved in metabolism and their impact on oxidative stress status. ⋯ Different dietary oils modify the lipid composition of the plasma and liver, local and systemic antioxidant statuses, and the activity of the key enzymes of lipid metabolism. The interrelation between Ca(2+) and nitrite plus nitrate could be the causal factor underlying the observed changes.
