• Monounsaturated fat - Wikipedia, the free encyclopedia - "Monounsaturated fats are found along with saturated fat in natural foods such as red meat, whole milk products, nuts and high fat fruits such as olives and avocados. Olive oil is about 75% monounsaturated fat while tea seed oil is commonly over 80% monounsaturated fat. Canola oil and Cashews are both about 58% monounsaturated fat. Tallow (beef fat) is about 50% monounsaturated fat and lard is about 40% monounsaturated fat. Other sources include macadamia nut oil, grapeseed oil, groundnut oil (peanut oil), sesame oil, corn oil, popcorn, whole grain wheat, cereal, oatmeal, safflower oil, sunflower oil, tea-oil Camellia, and avocado oil"
• Healthy oil components may fight pancreatitis - Nutra USA, 1/3/12 - "They found that the oleic acid and hydroxytyrosol – both of which are present in a particularly high concentration in virgin olive oil and omega-3 polyunsaturated fatty acids – offered protection from inflammatory damage from induced pancreatitis in pancreatic cells" - See Mega Twin EPA at iHerb and Jarrow Max DHA at iHerb and my olive Oil mayonnaise recipe.
• Olive Oil Linked to Reduced Stroke Risk - WebMD. 6/15/11 - "seniors who regularly used this healthy monounsaturated fat had a 41% lower risk of stroke compared to their counterparts who never used olive oil ... So what exactly is it about olive oil that may lower stroke risk? There are several theories, she says. It may be that people choose olive oil over saturated, artery-clogging fats. “Moreover, previous research found that the polyphenols from virgin olive oil account specifically for its ability to lower oxidized low-density lipoprotein (LDL)” or bad cholesterol. High cholesterol levels are a known risk factor for stroke ... Olive oil is a healthy fat and it can reduce cholesterol and inflammation, and has been shown to help reduce the incidence of heart disease" - Click here for my olive oil mayonnaise recipe.  See olive leaf extracts at iHerb.
• Fatty Acids and Cognitive Decline in Women - Medscape, 6/13/11 - "In this cohort of older women, greater MUFA intake was associated with less cognitive decline over a 3-year period. Previous studies generally but not invariably support this association. One previous prospective study found greater dietary MUFA intake to be associated with less cognitive decline,[10] a second found a trend in the same direction,[9] a third found a trend in the same direction in restricted analyses,[6] and three others were null.[7,8,11] None of the null studies had multiple measures of diet; one assessed diet using a measure of fatty acid composition of erythrocyte membranes,[7] but that study assessed cognitive decline exclusively using the Mini-Mental State Examination, which is probably not as sensitive as the neuropsychological test battery used in this study ... MUFA is thought to be one of the major protective components of the traditional Mediterranean diet, in which it is derived primarily from olive oil (median 46 g/d).[10] Two recent prospective studies of the Mediterranean diet have found greater adherence to be associated with less cognitive decline and lower incidence of Alzheimer's disease (AD).[31,32] One of these studies found an effect of the Mediterranean diet on an individual cognitive domain, namely memory.[31] This finding is consistent with the observed protective effect of MUFA on memory in the WHI CCW. In addition, the current study found an association between MUFA and less decline in visual–spatial abilities (copying and matching), a finding not previously made to the knowledge of the authors of the current study. Decline in visuospatial function has been associated with driving errors in older adults[33] and has also been suggested as a potential predictor (along with amnestic impairment) of transition from mild cognitive impairment to AD ... Several pathways may explain the apparent relationship between MUFA intake and cognitive function. MUFA and MUFA derivatives have antiinflammatory effects in vivo,[35,36] which may be important because chronic inflammation appears to be a precursor of symptomatic AD.[37–39] Oxidative stress has also been demonstrated in patients with mild cognitive impairment and AD,[40] and derivatives from MUFA, including low-molecular-weight phenols, have been found to have antioxidant effects.[41] MUFA may also exert their potentially beneficial effects on cognition indirectly by decreasing cardiovascular risk by reducing macrophage uptake of plasma oxidized low-density lipoprotein, apolipoprotein B, and f triglycerides" - Click here for my olive oil mayonnaise recipe.
• Eating poorly can make you blue: Trans-fats increase risk of depression, while olive oil helps avoid risk - Science Daily, 1/26/11 - "the participants with an elevated consumption of trans-fats (fats present in artificial form in industrially-produced pastries and fast food, and naturally present in certain whole milk products) "presented up to a 48% increase in the risk of depression when they were compared to participants who did not consume these fats," ... In addition, the study demonstrated a dose-response relationship, "whereby the more trans-fats were consumed, the greater the harmful effect they produced in the volunteers," ...Furthermore, the team, ... also analyzed the influence of polyunsaturated fats (abundant in fish and vegetable oils) and of olive oil on the occurrence of depression. "In fact, we discovered that this type of healthier fats, together with olive oil, are associated with a lower risk of suffering depression,""
• Essential oil pill prevents PMS, study suggests - Science Daily, 1/16/11 - "Women who were given capsules containing 2 grams of a combination of gamma linolenic acid, oleic acid, linoleic acid, other polyunsaturated acids and vitamin E reported significantly eased PMS symptoms at both 3 and 6 months after they began the treatment" - See borage oil products at iHerb (GLA) and Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at iHerb.  Oleic acid is omega-9 in which olive oil is a good source.  Linoleic acid is omega-6.  Most Americans get about 10 to 20 times too much omega-6 to begin with.  I don't know why they included it.  It makes me wonder about some of the researchers.  If they are showing a benefit, I would guess it's from the other ingredients and not the omega-6.  Gamma linolenic acid is an omega-6 also but it's a form that most don't get enough of.
• Fruit, vegetables, and olive oil and risk of coronary heart disease in Italian women: the EPICOR Study - Am J Clin Nutr. 2010 Dec 22 - "aimed to investigate the association between consumption of fruit, vegetables, and olive oil and the incidence of coronary heart disease (CHD) in 29,689 women enrolled between 1993 and 1998 ... A strong reduction in CHD risk among women in the highest quartile of consumption of leafy vegetables (hazard ratio: 0.54; 95% CI: 0.33, 0.90; P for trend = 0.03) and olive oil (hazard ratio: 0.56; 95% CI: 0.31, 0.99; P for trend = 0.04) was found. In contrast, no association emerged between fruit consumption and CHD risk"
• Olive oil protects liver from oxidative stress, rat study finds - Science Daily, 10/29/10 - "researchers separated the rats into a control group, an olive oil group, and 6 groups that were exposed to the herbicide '2,4-Dichlorophenoxyacetic acid' with or without either whole olive oil, or one of two oil extracts -- the hydrophilic fraction or the lipophilic fraction. All rats given the herbicide showed signs of significant liver damage. However, extra virgin olive oil and hydrophilic fraction intake induced a significant increase in antioxidant enzyme activity and a decrease in markers of liver damage ... The hydrophilic fraction of olive oil seems to be the effective one in reducing toxin-induced oxidative stress, indicating that hydrophilic extract may exert a direct antioxidant effect on hepatic cells" - See olive leaf extracts at iHerb.
• Olive oil compounds may boost cardiac fat oxidation: Study - Nutra USA, 10/21/10 - "Obese rats supplemented with olive oil, oleuropein, and cafeic acid had higher oxygen consumption, increased fat-oxidation, and lower carbon dioxide production than non supplemented obese rats" - [Abstract] - See olive leaf extracts at iHerb.
• Key mechanism links virgin olive oil to protection against breast cancer - Science Daily, 6/30/10 - "virgin olive oil is associated with higher incidences of benign breast tumours and at the same time with a decrease in the activity of the p21Ras oncogene, which spurs uncontrolled cell proliferation and stimulates the growth of tumours. In addition, olive oil suppresses the activity of some proteins, such as the AKT, essential for the survival of cells since they prevent apoptosis, the cell's "suicide" programme. Between proliferation and apoptosis in tumour cells, these effects tip the balance towards cell death, thereby slowing the growth of tumours" - See olive leaf extracts at iHerb.
• Olive oil could guard against developing ulcerative colitis - Science Daily, 5/3/10 - "those with the highest intake of oleic acid had a 90 per cent lower risk of developing the disease ... Oleic acid seems to help prevent the development of ulcerative colitis by blocking chemicals in the bowel that aggravate the inflammation found in this illness ... We estimate that around half of the cases of ulcerative colitis could be prevented if larger amounts of oleic acid were consumed. Two-to-three tablespoons of olive oil per day would have a protective effect"
• Eating Fish, Nuts And Olive Oil May Be Associated With Reduced Risk Of Age-related Blindness - Science Daily, 5/15/09 - "Individuals who consumed higher levels of trans-unsaturated fats—found in baked goods and processed foods—were more likely to have late AMD, whereas those who consumed the most omega-three fatty acids were less likely to have early AMD. "Olive oil intake (100 milliliters or more per week vs. less than 1 milliliter per week) was associated with decreased prevalence of late AMD," the authors write. "No significant associations with AMD were observed for intakes of fish, total fat, butter or margarine.""
• Source Of Major Health Benefits In Olive Oil Revealed - Science Daily, 4/1/09 - "Scientists have pinned down the constituent of olive oil that gives greatest protection from heart attack and stroke. In a study of the major antioxidants in olive oil, Portuguese researchers showed that one, DHPEA-EDA, protects red blood cells from damage more than any other part of olive oil"
• For Fats, Longer May Not Be Better - Science Daily, 1/8/09 - "Researchers have uncovered why some dietary fats, specifically long-chain fats, such as oleic acid (found in olive oil), are more prone to induce inflammation. Long-chain fats, it turns out, promote increased intestinal absorption of pro-inflammatory bacterial molecules called lipopolysaccharides (LPS)"
• New Anti-cancer Components Of Extra-virgin Olive Oil Revealed - Science Daily, 12/17/08 - "Extra-virgin olive oil is the oil that results from pressing olives without the use of heat or chemical treatments. It contains phytochemicals that are otherwise lost in the refining process. Menendez and colleagues separated the oil into fractions and tested these against breast cancer cells in lab experiments. All the fractions containing the major extra-virgin phytochemical polyphenols (lignans and secoiridoids) were found to effectively inhibit HER2"

• Beneficial effects of combined olive oil ingestion and acute exercise on postprandial TAG concentrations in healthy young women - Br J Nutr. 2012 Jan 23:1-7 - "Foods high in monounsaturated fat, such as olive oil, and endurance exercise are both known to independently reduce postprandial TAG concentrations. We examined the combined effects of exercise and dietary fat composition on postprandial TAG concentrations in nine healthy pre-menopausal females (age 26·8 (sd 3·3) years, BMI 22·3 (sd 2·0) kg/m2). Each participant completed four, 2 d trials in a randomised order: (1) butter-no exercise, (2) olive oil-no exercise, (3) butter-exercise, (4) olive oil-exercise. On day 1 of the exercise trials, participants walked or ran on a treadmill for 60 min. On the no-exercise trials, participants rested on day 1. On day 2 of each trial, participants rested and consumed an olive oil meal (saturated fat 15 % and unsaturated fat 85 %) or a butter meal (saturated fat 71 % and unsaturated fat 29 %) for breakfast ... A significant main effect on physical activity (exercise or control) was obtained for plasma TAG concentration (three-way ANOVA, P = 0·043), and the total area under the concentration v. time curve for TAG was 26 % lower on the olive oil-exercise trial (4·40 (sd 0·40) mmol × 6 h/l) than the butter-no exercise trial (5·91 (sd 1·01) mmol × 6 h/l) (one-way ANOVA, P = 0·029). These findings suggest that the combination of exercise and a preference for monounsaturated dietary fat intake in the form of olive oil may be most beneficial for reducing postprandial TAG concentrations"
• Substitution of Standard Soybean Oil with Olive Oil-Based Lipid Emulsion in Parenteral Nutrition: Comparison of Vascular, Metabolic, and Inflammatory Effects - J Clin Endocrinol Metab. 2011 Aug 10 - "Soybean oil-based lipid emulsions are the only Food and Drug Administration-approved lipid formulation for clinical use in parenteral nutrition (PN). Recently concerns with its use have been raised due to the proinflammatory effects that may lead to increased complications because they are rich in ω-6 polyunsaturated fatty acids ... Soybean oil-PN increased systolic blood pressure compared with olive oil-PN (P < 0.05). Soybean oil PN reduced brachial artery flow-mediated dilatation from baseline (-23% at 4 h and -25% at 24 h, both P < 0.01); in contrast, olive oil PN, lipid free PN, and saline did not change either systolic blood pressure or flow-mediated dilatation. Compared with saline, soybean oil PN, olive oil PN, and lipid free PN similarly increased glucose and insulin concentrations during infusion (P < 0.05). There were no significant changes in plasma free fatty acids, lipid profile, inflammatory and oxidative stress markers, immune function parameters, or sympathetic activity between soybean oil- and olive oil-based lipid emulsions. Conclusion: The 24-h infusion of PN containing soybean oil-based lipid emulsion increased blood pressure and impaired endothelial function compared with PN containing olive oil-based lipid emulsion and lipid-free PN in healthy subjects. These vascular changes may have significant implications in worsening outcome in subjects receiving nutrition support"
  • Parenteral nutrition - Wikipedia, the free encyclopedia - "Parenteral nutrition (PN) is feeding a person intravenously, bypassing the usual process of eating and digestion. The person receives nutritional formulas that contain nutrients such as salts, glucose, amino acids, lipids and added vitamins. It is called total parenteral nutrition (TPN) or total nutrient admixture (TNA) when no food is given by other routes"
• Olive oil intake is inversely related to cancer prevalence: A systematic review and a meta-analysis of 13800 patients and 23340 controls in 19 observational studies - Lipids Health Dis. 2011 Jul 30;10(1):127 - "Dietary fat, both in terms of quantity and quality, has been implicated to cancer development, either positively or negatively. The aim of this work was to evaluate whether olive oil or monounsaturated fat intake was associated with the development of cancer. A systematic search of relevant studies, published in English, between 1990 and March 1, 2011, was performed through a computer-assisted literature tool (i.e., Pubmed). In total 38 studies were initially allocated; of them 19 case-control studies were finally studied (13800 cancer patients and 23340 controls were included). Random effects meta-analysis was applied in order to evaluate the research hypothesis. It was found that compared with the lowest, the highest category of olive oil consumption was associated with lower odds of having any type of cancer (log odds ratio = -0.41, 95%CI -0.53, -0.29, Cohran's Q=47.52, p=0.0002, I-sq=62%); the latter was irrespective of the country of origin (Mediterranean or non-Mediterranean). Moreover, olive oil consumption was associated with lower odds of developing breast cancer (logOR=-0,45 95%CI -0.78 to -0.12), and a cancer of the digestive system (logOR=-0,36 95%CI -0.50 to -0.21), compared with the lowest intake.The strength and consistency of the findings states a hypothesis about the protective role of olive oil intake on cancer risk. However, it is still unclear whether olive oil's monounsaturated fatty acid content or its antioxidant components are responsible for its beneficial effects" - Note:  That last sentence has been my question on many of the olive oil studies.  I still use my olive oil mayonnaise made with the extra light plus I take the olive oil extract capsules.  I'm not going to suffer through the taste of the extra virgin olive oil.  See olive leaf extracts at iHerb.
• Adherence to the Mediterranean diet reduces mortality in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Spain) - Br J Nutr. 2011 May 17:1-11 - "Epidemiological studies show that adherence to a Mediterranean diet (MD) increases longevity; however, few studies are restricted to Mediterranean populations or explore the effect of a MD pattern that directly incorporates olive oil. Therefore the relationship between adherence to the MD and mortality was studied within the the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Spain) ... Risk of all-cause and cause-specific mortality was assessed according to the level of adherence to a relative MD (rMED) score, measured using an 18-unit scale incorporating nine selected dietary components. A high compared with a low rMED score was associated with a significant reduction in mortality from all causes (hazard ratio (HR) 0.79; 95 % CI 0.69, 0.91), from CVD (HR 0.66; 95 % CI 0.49, 0.89), but not from overall cancer (HR 0.92; 95 % CI 0.75, 1.12). A 2-unit increase in rMED score was associated with a 6 % (P < 0.001) decreased risk of all-cause mortality. A high olive oil intake and moderate alcohol consumption contributed most to this association. In this Spanish cohort, following an olive oil-rich MD was related to a significant reduction in all-cause mortality, and reduced the risk of mortality from CVD. These results support the important role that the MD pattern has on reducing mortality in Mediterranean countries" - Click here for my olive oil mayonnaise recipe.
• Oleate-enriched diet improves insulin sensitivity and restores muscle protein synthesis in old rats - Clin Nutr. 2011 Jun 21 - "Twenty-four 25-month-old rats were fed either a control diet (OC), an oleate-enriched diet (HFO) or a palmitate-enriched diet (HFP) for 16 weeks. MPS using labeled amino acids and mTOR activation were assessed after AA and insulin anabolic stimulation to mimic postprandial state ... IR and systemic and adipose tissue inflammation (TNFα and IL1β) were improved in the HFO group. Muscle genes controlling mitochondrial β-oxidation (PPARs, MCAD and CPT-1b) were up-regulated in the HFO group. AA and insulin-stimulated MPS in the HFO group only, and this stimulation was related to activation of the Akt/mTOR pathway ... The age-related MPS response to anabolic signals was improved in rats fed an oleate-enriched diet. This effect was related to activation of muscle oxidative pathways, lower IR, and a decrease in inflammation"
  • Oleate - dictionary.com - "a salt or ester of oleic acid" - Note:  Oleic acid is omega-9 like in olive oil.
  • Palmitate definition - medterms.com - "An antioxidant and a vitamin A compound that is added to low-fat and fat-free milk to replace the vitamin content lost through the removal of milk fat. Palmitate (more formally known as retinyl palmitate) contains palmitic acid, a 16-carbon saturated fatty acid, which is the major fatty acid found in palm oil. The palmitic acid is attached to the alcohol form of vitamin A, called retinol, to make vitamin A stable in milk. The name "palmitate" comes from the French "palmitique" from palmite, the pith of the palm tree"
• Effect of a traditional Mediterranean diet on apolipoproteins B, A-I, and their ratio: A randomized, controlled trial - Atherosclerosis. 2011 May 6 - "Apolipoprotein (Apo)B, ApoA-I, and their ratio could predict coronary heart disease (CHD) risk more accurately than conventional lipid measurements. Our aim was to assess the effect of a traditional Mediterranean diet (TMD) on apolipoproteins ... Participants assigned to a low-fat diet (control) (n=177), or TMDs (TMD+virgin olive oil (VOO), n=181 or TMD+nuts, n=193) received nutritional education and either free VOO (ad libitum) or nuts (dose: 30g/day). A 3-month evaluation was performed ... Both TMDs promoted beneficial changes on classical cardiovascular risk factors. ApoA-I increased, and ApoB and ApoB/ApoA-I ratio decreased after TMD+VOO, the changes promoting a lower cardiometabolic risk. Changes in TMD+VOO versus low-fat diet were -2.9mg/dL (95% CI, -5.6 to -0.08), 3.3mg/dL (95% CI, 0.84 to 5.8), and -0.03mg/dL (-0.05 to -0.01) for ApoB, ApoA-I, and ApoB/ApoA-I ratio, respectively ... Individuals at high-cardiovascular risk who improved their diet toward a TMD pattern rich in virgin olive oil, reduced their Apo B and ApoB/ApoA-I ratio and improved ApoA-I concentrations" - The question is; is it the polyphenols or the omega-9 or both in the virgin olive oil responsible for the benefit?

• Dietary Intake of Cholesterol Is Positively and Use of Cholesterol-Lowering Medication Is Negatively Associated with Prevalent Age-Related Hearing Loss - J Nutr. 2011 May 25 - "After multivariable adjustment, the likelihood of prevalent hearing loss increased from the lowest (reference) to the highest quartile of dietary cholesterol intake (P-trend = 0.04). Among persons self-reporting statin use (n = 274), a 48% reduced odds of prevalent hearing loss was observed after multivariable adjustment [OR = 0.52 (95% CI = 0.29-0.93)]. Participants in the second and 3rd quartiles of dietary monounsaturated fat intake compared with those in the first quartile (reference) had a significantly reduced risk of hearing loss progression 5 y later [multivariable-adjusted OR = 0.39 (95% CI = 0.21-0.71)] and [OR = 0.51 (95% CI = 0.29-0.91)], respectively. Our results suggest that a diet high in cholesterol could have adverse influences on hearing, whereas treatment with statins and consumption of monounsaturated fats may have a beneficial influence"
• Inverse association between serum phospholipid oleic acid and insulin resistance in subjects with primary dyslipidaemia - Clin Nutr. 2011 Mar 30 - "oleic acid (OA) ... By adjusted logistic regression, including the proportions of other fatty acids known to relate to IR, the odds ratios (OR) (95% confidence intervals) for IR were 0.75 (0.62-0.92) for 1% increase in OA and 0.84 (0.71-0.99) for 1% increase in linoleic acid. Other fatty acids were unrelated to IR. When using the alternate definition of IR, OA remained a significant predictor (0.80 [0.65-0.99]) ... Higher phospholipid proportions of OA relate to less IR, suggesting an added benefit of increasing olive oil intake within the Mediterranean diet" - Note: I saw olive oil mayonnaise advertised and I thought that would be a good way to increase the omega-9 in my diet. When I read the label in the store, olive oil was the main ingredient however it had three omega-6 oils listed after that so I’m sure it had much more omega-6 than omega-9. Bottom line, I started making my own omega-9 mayo. See the recipe at http://allrecipes.com//HowTo/making-mayonnaise/Detail.aspx.
