Fatty acid supplementation increases muscle mass and function in older adults, but the effect of habitual dietary intake is uncertain. Therefore, the objective of this study was to examine the association between habitual dietary fat intake and risk of muscle weakness and lower-extremity functional impairment (LEFI) in older adults. ⋯ Habitual intake of SFA was associated with increased risk of LEFI. By contrast, habitual intake of MUFA and PUFA were associated with lower risk of physical performance impairment.

No evidence based recommendations for micronutrient requirements during paediatric critical illness are available, other than those arising from recommended nutrient intakes (RNI) for healthy children and expert opinion. ⋯ During critical illness, micronutrients should be provided in sufficient amounts to meet reference nutrient intakes for age. Although, there is insufficient data to recommend routine supplementations of micronutrients at higher doses during critical illness, the 'absence of evidence should not imply evidence of absence', and well designed prospective studies are urgently needed to elucidate paediatric micronutrient requirements during critical illness. The absence of reliable biomarkers make it challenging to determine whether low serum levels are reflective of a true deficiency or as a result redistribution, particularly during the acute phase of critical illness. As more children continue to survive a PICU admission, particularly those with complex diseases micronutrient supplementation research should also be inclusive of the recovery phase following critical illness.

Randomized Controlled Trial
Açaí (Euterpe oleracea Mart.) and juçara (Euterpe edulis Mart.) juices improved HDL-c levels and antioxidant defense of healthy adults in a 4-week randomized cross-over study.
To evaluate the effects of moderate-term açaí and juçara juice intake on fasting glucose, lipid profile, and oxidative stress biomarkers in healthy subjects. ⋯ The results indicated a positive impact of regular consumption of açaí and juçara juices on the HDL-c levels, as well as on the antioxidant enzyme activities, which may contribute to cardiovascular health.
