Abstract
The phenolic profiles of extra virgin olive oils (EVOOs) may influence their cardiovascular benefits. In a randomized crossover of acute EVOO intake on platelet function, participants (n=9) consumed 40 mL of EVOO weekly. EVOOs were matched for total phenolic content and were either tyrosol-poor with 1:2 oleacein/oleocanthal (D2i0.5), or 2:1 oleacein/oleocanthal (D2i2), or predominantly tyrosol (D2i0). Ibuprofen provided a platelet inhibition control. Blood was collected pre- and 2 hr post-EVOO intake. D2i0.5 and D2i2 reduced 1 µg/mL collagen-stimulated maximum platelet aggregation (Pmax), with effects best correlated to oleocanthal intake (R=0.56, P=0.002). Total phenolic intake was independently correlated to eicosanoid production inhibition, suggesting that cyclooxygenase blockade was not responsible for the Pmax inhibition. Five participants exhibited >25% ΔPmax declines with D2i0.5 and D2i2 intake and plasma metabolomic profiles discriminated subjects by oil responsivity. Platelet responses to acute EVOO intake are associated with oil phenolic composition and may be influenced by diet.

Abstract
PUFA n-3 diets have hypolipemic and cardiovascular protection properties, however their effects on liver lipids are not well established. This work aimed to find out the acceptability and effects of diets containing olive oil-fried sardines on serum cholesterol, liver lipid and fatty acids profile in hypercholesterolemic growing Wistar rats. Hypercholesterolemia was induced for three weeks by a casein plus DL-methionine, olive oil and cholesterol plus bovine bileas cholesterol-raising agent. Rats were later transferred for three weeks to semisynthetic diets containing casein plus DL-methionine and olive oil (CO), casein plus DLmethionine, olive oil and the cholesterol-raising agent (COC), sardines fried in olive oil (S), and sardines friedin olive oil and the cholesterol-raising agent (SC). SC or S diets were well accepted by the rats. The SC-diet markedly blocked and reversed the hypercholesterolemic induction of the cholesterol-raising agent. The cholesterol withdrawal decreased serum cholesterol in CO and S dietsby decreasing the serum non-HDL-cholesterol content but the S-diet totally normalised the serum cholesterol. Fried sardines did not change the triacylglycerol, free, esterified and total cholesterol contents of liver. Although long PUFA n-6 and PUFA n-3 were decreased by the dietary cholesterol, olive oil-fried sardine consumption maintained the docosahexaenoic acid and thedocosahexaenoic acid/linolenic acid ratio in liver and cholesterol ester fraction at a high level. Olive oil fried sardines blocked the hypercholesterolemic effect of the diet containing cholesterol and help normalising lipoprotein profile in a rather short period. The oleic acid esterification of cholesterol was kept high in all experimental diets as a mechanism to maintain the liver cholesterol ester/free cholesterol ratio as high as possible. The fat in the oliveoil-fried sardines was used similarly to the oleic acid by the liver of hypercholesterolemic rats but increased its PUFA n-3 content in the total liver and its cholesterol ester fraction.

Abstract
The aim of this paper was to design and analyse the nutritional composition (fatty acid profile, cholesterol, mineral and amino acid content) of low-fat frankfurters enriched with n-3 polyunsaturated fatty acids (PUFA) (using algal oil to add 400mg of docosahexanoic acid - DHA/100g of product) as affected by the addition of seaweed (5.5% Himanthalia elongata) and the partial substitution (50%) of animal fat by olive oil (as a source of monounsaturated fatty acids - MUFA) or combinations of olive oil and seaweed. Reduction of NaCl level was also studied. The presence of algal oil produced frankfurters with high long-chain n-3 PUFA contents. The partial substitution of the pork fat by olive oil reduced (P<0.05) saturated fatty acids (SFA) and promoted (P<0.05) MUFA. A healthier lipid formulation (algal and olive oils and the reducing animal fat) produced a good balance of MUFA/SFA, PUFA/SFA and n-6/n-3 ratios. Although adding seaweed had little effect on the lipid and amino acid profiles of frankfurters, it does constitute a means to produce low-sodium products with important dietary fibre content, with better Na/K ratios and rich in Ca.

Abstract
Walnut consumption produces beneficial cardiovascular effects. The aim of the present study is to compare the effects of meat enriched in walnut paste (WM) and low-fat meat (LM) consumptions on platelet aggregation, plasma thromboxane A2(TXA2, measured as TXB2), prostacyclin I2(PGI2, as 6-keto-PGF1α) and the thrombogenic ratio (TXB2/6-keto-PGF1α) in volunteers at high CVD risk. Twenty-two adults were placed on a random, non-blinded crossover study involving two test periods (five portions WM/week for 5 week; five portions LM/week for 5 week) separated by a 4- to 6-week washout period. The participants were asked to complete a diet record throughout the study. Platelet aggregation, plasma TXB2, 6-keto-PGF1αproduction and the TXB2/6-keto-PGF1α ratio were determined at baseline and at weeks 3 and 5 for the two dietary periods. The WM diet contains a lower SFA content, a higher concentration of PUFA and a more favourablen-6/n-3 ratio than the LM diet. Significant time × treatment interactions were observed for TXB2(P = 0·048) and the TXB2/6-keto-PGF1α ratio (P = 0·028). The WM diet significantly increased the level of 6-keto-PGF1α (P = 0·037) and decreased the TXB2/6-keto-PGF1α ratio (P = 0·048). At week 5, significant differences (P < 0·05) between treatments were found for maximum aggregation rate, TXB2values and the TXB2/6-keto-PGF1α ratio. The effects on TXB2and the TXB2/6-keto-PGF1α ratio were time-course dependent (P = 0·019 and 0·011, respectively). The WM and LM diets reduced TXB2levels most (P = 0·050) in obese individuals, while the TXB2/6-keto-PGF1α ratio decreased most (P = 0·066) in volunteers whose serum cholesterol levels were ≥ 2200 mg/l. The WM diet should be considered a functional meat because it improves the thrombogenic status mainly in individuals with high-cholesterol levels or high BMI.

Abstract
Increased HDL-cholesterol levels have been associated with lower coronary heart disease (CHD) risk. However, HDL are heterogeneous lipoproteins, and particles enriched in apolipoprotein (Apo) AII have been associated with increased CHD risk. We examined the effect of dietary intervention on HDL composition in 14 postmenopausal women subjected to two consecutive diet periods, i.e., an oleic acid sunflower oil diet followed by a palmolein diet, each lasting 4 wk. The linoleic acid was kept at 4% total energy and the cholesterol intake at 400 mg/d. The palmolein diet increased serum total cholesterol (TC) (P < 0.001), phospholipids (P < 0.001), Apo AII (P < 0.001), HDL cholesterol (P < 0.05), HDL lipids (P < 0.05), HDL proteins (P < 0.01) and the HDL total mass (P < 0.05). The HDL cholesterol/Apo AI ratio was increased 22.0% (P < 0.05), whereas the HDL cholesterol/Apo AII and the Apo AI/Apo AII ratios were decreased 19.4% (P < 0.01) and 30.4%, (P < 0.001), respectively. When the effects of the dietary intervention were examined according to the cholesterolemia status (< or >6.2 mmol/L), the most significant changes (P < 0.001) were related to Apo AII levels. Moreover, a significant dietary oil by cholesterol level interaction was found for Apo AII and the HDL cholesterol/Apo AII ratio. In summary, a palmolein diet increased TC and HDL cholesterol compared with oleic acid sunflower oil diet; however, the increase in Apo AII but not in Apo AI suggests the impairment of reverse cholesterol transport and potentially an increase in CHD risk. This effect was more marked in women with serum TC > 6.2 mmol/L.

Abstract
The present paper compares the effects of two monounsaturated oils, extra virgin olive oil (EVOO) and high-oleic acid sunflower oil (HOSO), on serum and LDL peroxides, eicosanoid production and the thrombogenic ratio (thromboxane (TX) B2:6-keto-prostaglandin F1alpha) in fourteen non-obese post-menopausal women. The subjects, mean age 63 (SD 11) years, were assigned to two consecutive oleic acid-rich 28 d dietary periods. EVOO and HOSO represented 62 % of the total lipid intake and were used as the only culinary fat during the first and second dietary periods respectively. Serum peroxides, plasma alpha-tocopherol and TXB2 levels in stimulated platelet-rich plasma (PRP-TXB2) were significantly higher (P < 0.01, P < 0.001, and P < 0.05, respectively) after the HOSO diet than after the EVOO diet. The relationship between the serum cholesterol level (< 6.21 mmol/l or > or = 6.21 mmol/l) and the type of dietary oil on eicosanoids, peroxides and alpha-tocopherol were evaluated by two-way ANOVA. Dietary oil significantly affected (P < 0.05) the PRP-TXB2 level, whereas serum and LDL peroxides were significantly affected (P < 0.001 and P < 0.01, respectively) by the serum cholesterol level. The plasma alpha-tocopherol level was significantly affected by the serum cholesterol level and the type of dietary oil (both P < 0.001). No significant relationships were found between serum cholesterol levels, serum peroxide or LDL peroxide levels, plasma alpha-tocopherol concentrations or alpha-tocopherol intakes with eicosanoid production or the thrombogenic ratio due to dietary changes. However, in spite of their higher alpha-tocopherol levels, hypercholesterolaemic subjects showed increased peroxidation in serum and LDL in comparison with normocholesterolaemic subjects on the HOSO diet in comparison with the EVOO diet. These findings suggest that differences in the type of minor compounds, as well as in the concentration of linoleic acid, in both these monounsaturated oils may play an important role in modulating eicosanoid production and lipoprotein peroxidation when they constitute a large proportion of the diet of post-menopausal women.
