This paper investigates the possibilities of using two types vegetable oil emulsions as animal fat substitutes in cooked emulsified sausages. The sausage samples were made with full or partial substitution pork back emulsions. use oils meat formulations led to a reduction SFA/UFA ratio. PUFA/SFA ratio was improved where substituted chia (samples 2, 4 and 6), this most probably resulted from emu...

The study was aimed at assessing the effect of dietary supplementation with black pepper (Piper nigrum) on chemical and fatty acid composition in meat rainbow trout (Oncorhynchus mykiss W.), farmed a recirculating system.
 Rainbow were distributed two groups – experimental fed 1% powdered extract from (BPE) control (C) without extract. After end experiment, 6 fish each group euthanized, fi...

Reductions in dietary fat, saturated fat, and cholesterol have been recommended to reduce the risk of heart disease in our society. The effects of these modifications on human cytokine production and immune responses have not been well studied. 22 subjects > 40 yr of age were fed a diet approximating that of the current American (14.1% of calories as saturated fatty acids, [SFA], 14.5% monounsa...

BACKGROUND Consumption of tuna or other broiled or baked fish, but not fried fish, is associated with fewer subclinical brain abnormalities on magnetic resonance imaging (MRI). We investigated the association between plasma phospholipid omega-3 polyunsaturated fatty acids (PUFAs), objective biomarkers of exposure, and subclinical brain abnormalities on MRI. METHODS AND RESULTS In the communit...

BACKGROUND Experimental elevation of nonesterified fatty acids (NEFAs) impairs endothelial function, but the effect of NEFA composition is unknown. OBJECTIVE The objective was to test the effect of acute elevation of NEFAs enriched with either saturated fatty acids (SFAs) or SFAs with long-chain (LC) n-3 (omega-3) PUFAs on vascular function measured via flow-mediated dilatation (FMD), laser D...

Our aim was to study the influence of weight loss on the fatty acid (FA) composition of liver and erythrocyte phospholipids and oxidative stress status in obese, non-alcoholic, fatty liver disease (NAFLD) patients. Seven obese NAFLD patients who underwent subtotal gastrectomy with a gastro-jejunal anastomosis in roux and Y were studied immediately and 3 months after surgery. Seven non-obese pat...

The objective of this study was to compare the fatty acid (FA) composition of intramuscular fat from the LM of 3 divergent breeds of cattle: Angus (AN, n = 9), Brahman (BR, n = 7), and Romosinuano (RM, n = 11). Cattle were blocked by breed and finished 129 d before slaughter in one year and 157 d in the next year. Longissimus muscle samples were collected from each carcass between the 10th and ...

To the Editor: Longitudinal studies suggest that nutrition plays an important role in healthy aging.1 As people age, eventually they become less active, theirmetabolism slows, and energy requirement and dietary intake decrease.2 At the same time, nutrient requirementsmayeven increase as the ability to absorb and utilizemany nutrients becomes less efficient, thus maintaining a nutrient-dense and...

The aim of this study was to estimate genetic parameters for pork intramuscular fatty acid (FA) composition and indices for desaturase and elongase activities involved in n-3 and n-6 PUFA metabolism. The LM of 437 slaughter pigs was analyzed for FA composition (expressed as g/100 g of FA). Indices for enzyme activities were calculated from product to precursor FA ratios. Genetic parameters were...
