Potential Risks Of Olive Oil
The benefits of olive oil don’t apply to all individuals. Consider these health risks when consuming olive oil:
Olive oil is a high-calorie food that can contribute to obesity, defined as a body mass index of 30 or more. Obesity has several health risks. For some individuals, cutting fat, even olive oil, can be a better strategy for their health.
Eating too much olive oil can be harmful for anyone. Remember that one serving is just one tablespoon. The benefits of the Mediterranean diet come from several factors not just olive oil. The diet is high in fish and seafood, low in red meat, and rich in fruits and vegetables.
Simply adding olive oil to your existing eating habits doesnt mean youre eating a healthy diet. You may need to make more changes in the way you’re eating to get all the health benefits of the Mediterranean diet.

Olive Oil And The Liver
A 2018 review of laboratory studies found that molecules in extra virgin olive oil may help prevent or repair liver damage.
How To Avoid Excess Weight Gain
Eating excess calories is only one reason for becoming overweight. Incorporating extra virgin olive oil into your diet can help counteract other factors responsible for fat buildup.
- Adding EVOO to your diet provides your body with important nutrients and all the healthy fats it needs, thus reducing the cravings that lead to nutrient-empty foods like soft drinks, cookies and breads.
- Consumption of man-made trans fats found in hydrogenated and refined vegetable oils interferes with numerous biochemical processes in the body and can cause serious health problems and contribute to weight gain. Using EVOO instead can begin reversing the negative effects of trans fats.
Many people consume EVOO strictly for its antioxidant power, but beyond that, the nutritional value of olive oil makes you full and satisfied. By feeding your body the healthy fats it needs and increasing your intake of olive oil, research shows you will feel more full for a longer period of time and be less tempted to overeat, making extra virgin olive oil an important aid in weight loss and improved health for adults and kids alike.

Olive Oil Is Rich In Healthy Monounsaturated Fats
Olive oil is the natural oil extracted from olives, the fruit of the olive tree.
About 14% of the oil is saturated fat, whereas 11% is polyunsaturated, such as omega-6 and omega-3 fatty acids .
But the predominant fatty acid in olive oil is a monounsaturated fat called oleic acid, making up 73% of the total oil content.
Studies suggest that oleic acid reduces inflammation and may even have beneficial effects on genes linked to cancer .
Monounsaturated fats are also quite resistant to high heat, making extra virgin olive oil a healthy choice for cooking.
Summary Olive oil is rich in monounsaturated oleic acid. This fatty acid is believed to have many beneficial effects and is a healthy choice for cooking.
Strengths And Limitations Of This Study
The randomised trial design comparing three dietary fat interventions minimised confounding and bias.
There was good compliance and participants were from the general community in a real life setting.
Objective measures of outcomeblood biochemistry and anthropometrywere used, minimising bias.
Participants were not blinded as to the intervention, and the intervention was relatively short term over 4weeks.

Help Reduce The Risk Of Strokes
A stroke is induced because of a disturbance of blood flow to your brain the disturbance can be caused by bleeding or a blood clot. As a result, strokes are the second most common cause of death in most developed countries, after heart attacks.
Many studies have found that using olive oil may reduce the chances of a stroke by up to 40%. The primary reason is that people who use extra virgin olive oil are essentially increasing the use of heart-healthy fats in their monounsaturated diet.
The combination of healthy fats, reduced oxidative stress, and a healthy diet always leads to better cardiovascular health and a reduced risk for strokes.
Quantity Vs Quality Of Hdl
Whats critical, then, is not the absolute amount of HDL cholesterol in your blood but how efficiently the HDL particles you have are removing excess cholesterol from your artery walls and trucking it back to your liver for disposal.
If you have a high HDL cholesterol level, but it is not functioning properly at reverse cholesterol transport because your diet is too high in fat, that high number may look good on your lab report, but your arteries may still be clogging up, warns Gomer.
Ultimately, we must ask: What happens to people after years and years? Who actually ends up with less heart disease? In every study, the rural Asians yes, the people with the low HDL levels win. Every time, the rural Asians beat out populations, like those of Crete, Greece, and Italy, with higher HDLs.

One of these is Helicobacter pylori, a bacterium that lives in your stomach and can cause stomach ulcers and stomach cancer.
Test-tube studies have shown that extra virgin olive oil fights eight strains of this bacterium, three of which are resistant to antibiotics .
A study in humans suggested that 30 grams of extra virgin olive oil, taken daily, can eliminate Helicobacter pylori infection in 1040% of people in as little as two weeks (
Extra virgin olive oil has antibacterial properties and has been found to be particularly effective against Helicobacter pylori, a type of bacterium that can cause stomach ulcers and stomach cancer.
Olive Oil Can Help Treat Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disease characterized by deformed and painful joints.
Though the exact cause is not well understood, it involves your immune system attacking normal cells by mistake.
Olive oil supplements appear to improve inflammatory markers and reduce oxidative stress in individuals with rheumatoid arthritis .
Olive oil seems particularly beneficial when combined with fish oil, a source of anti-inflammatory omega-3 fatty acids.
In one study, olive and fish oil significantly improved handgrip strength, joint pain and morning stiffness in people with rheumatoid arthritis (
Olive oil can help reduce joint pain and swelling from rheumatoid arthritis. The beneficial effects are greatly increased when combined with fish oil.

Cooking With Canola Oil
When people expose canola oil to high heat for long periods, a chemical reaction occurs that releases potentially unhealthful compounds.
To safely use canola oil, people can use it to quickly sauté vegetables, meat, or meat alternatives, making sure that the oil does not get too hot.
Manufacturers make vegetable oil from oilseeds, legumes, nuts, or the flesh of some fruits.
Vegetable oil contains the highest levels of polyunsaturated fats compared with olive, coconut, and canola oil.
Partially hydrogenated vegetable oils contain trans fats. Trans fats are unsaturated fatty acids with a different chemical structure. Clinical trials consistently report on the adverse effects of trans fats on risk factors for cardiovascular disease.
Trans fats are in a variety of processed foods such as margarine, baked goods, and deep-fried foods. Because of the dangers health experts associate with eating trans fats, manufacturers must include the trans fats content on food labels.
Olive Oil In Cooking And Smoke Point
When using oil for cooking, it is important to keep the heat level in mind. The smoke point is the temperature at which the oil begins to break down, become carcinogenic, and release smoke into the air. In other words, it is when the oil starts to burn.
If oil starts to burn or catch fire, a person should throw it away and start again.
The say that the following oils are relatively healthful for cooking and preparing food:

What This Might Mean
There just isnt enough research one way or another to claim the fruit or the oil made from it is dangerous. If you make the assumption that based on that study its mutagenic, then the next question would be whats causing that side effect.
Since the fatty acid profile of avocado oil vs olive oil isnt very different, it suggests these types fats are not the problem. If they were, we would expect to see similar mutagenic findings for olive oil.
Since refined oils are just that highly purified fat it would suggest that if there is a problematic compound in this fruit, only trace amounts would be present in the refined oil made from it.
In short, that study is a stronger case against eating whole avocados versus cooking with the oil.
But remember, all of this is theoretical. The only thing that we know for sure is that a study done at a cancer hospital in India found that the fruit and leaf in concentrations as little as 0.01% caused startling numbers of DNA mutations in the cultured human white bloods cells. That is concerning, but evaluating the same in the human body is a different thing, which has not been done.
Does the same happen after this food is digested? That deserves some serious research.
What Is Extra Virgin Olive Oil Made Up Of
Extra virgin olive oil, as we have already mentioned, is a fat, but in order to understand its specific properties, we must go deeper into its composition, which is made up of almost 98% triglycerides of three different types: oleic, linoleic and palmitic acids. The concentration of these components will depend on the variety of olives from which the extra virgin olive oil is made, but in this case, well focus on extra virgin olive oil made of picual variety, the most common in the Spain. Picual extra virgin olive oil has an 80% concentration of oleic acid. A big number of national and international researches find this ingredient with great health benefits, especially for the cardiovascular system. This is due to the fact that oleic acid is a monounsaturated fatty acid that belongs to the Omega-9 group.
In addition to the effect of triglycerides, other micronutrients, such as polyphenols and vitamin E, increase the nutritional value of this olive oil.

Fights Arthritis And Inflammation
Avocado Soybean Unsaponifiables is an extract made of 1/3 avocado and 2/3 soybean oil. In France, this formulation is used as a prescription treatment for osteoarthritis, sold under the brand name Piascledine. Multiple studies have found it offers significant improvement versus placebo and for patients with arthritis of the knee and hip, it reduced their need for pain relief from NSAIDs such as aspirin.
Even without the addition of soybean, theres research to suggest that the antioxidants in avocado help to offset some inflammatory responses in the body.
Meat creates lipid peroxides when it is cooked. In a study at UCLA, researchers measured the inflammatory markers in people who ate hamburgers with and without the avo slices on top.
There was significant vasoconstriction 2 hours following hamburger ingestion but that didnt happen when the fruit was included. Its believed this was due to the reduced activation of the NF-kappa B inflammatory pathway, thanks to the avocados antioxidant content.
The raw avocado has an ORAC value of 1,922 per 100g, which suggests it has even more antioxidants than kale of the same weight, which has a 1,770 ORAC. The bad news is that the oil of avocado will have very little antioxidants relative to the fresh fruit.

Can The Mediterranean Diet Help Reduce Ldl Cholesterol
Nearly twenty years ago two landmark randomized clinical trials appeared in The Lancet which forever changed the course of medicine for patients with coronary heart disease . The 4S study employed a cholesterol-lowering statin drug and reported a 30% mortality reduction. The Lyon Diet Heart Study utilized the Mediterranean diet and reported a 70% mortality reduction.
Subsequent studies of the Mediterranean diet have confirmed these findings and have also shown a reduced risk of cancer, diabetes, and Alzheimers disease. Subsequent statin studies have led the United States Food and Drug Administration to issue warnings regarding the increased risk of diabetes and decreased cognition with statin drugs. Paradoxically, statins have gone on to become a multi-billion dollar industry and the foundation of many cardiovascular disease prevention guidelines while the Mediterranean diet has often been ignored.
The authors of the study, Robert DuBroff and Michel de Lorgeril concluded we believe this statin-centric cholesterol-lowering approach to preventing CHD may be misguided. They further found.
The dramatic benefits of the Mediterranean diet are likely due to multiple mechanisms which do not directly involve cholesterol. Independent of cholesterol metabolism are the true fatal complications of coronary atherosclerosis thrombotic coronary occlusion, acute myocardial ischemia, left ventricular dysfunction, and malignant arrhythmias.
Its An Unsaturated Fat
All fat contains 9 calories per gram, but fats aren’t all created equal when it comes to their impact on your health, explains the American Heart Association. Saturated fats, which are found in full-fat dairy, some tropical plants and meats, and trans fats, which are mostly synthetic, can negatively affect your health by increasing inflammation, encouraging weight gain, and clogging your arteries. Transfats and saturated fats raise the level of LDL a harmful form of cholesterol in the blood, contributing to heart disease development. Unsaturated fats and monounsaturated fats can have a positive effect on your health when consumed in moderate amounts as part of an overall healthy diet.
The Academy of Nutrition and Dietetics suggests replacing foods that are higher in saturated fat with foods that are higher in unsaturated fats. You want just 10 percent, or fewer, or your daily calories to come from saturated fats, while unsaturated fats can make up 20 to 35 percent of daily calories. This means if you’re on a 2,000-calorie per day diet, aim to consume no more than 22 grams of saturated fat per day. But if you stick to unsaturated fats, you can enjoy between 44 and 77 grams a day while still following a healthy eating plan.
