No human studies directly link palm oil consumption to causing cancer, but research in mice suggests its main fatty acid, palmitic acid, can promote cancer cell spread (metastasis). Palm oil contains antioxidants but also saturated fats; a balanced diet focusing on unsaturated fats is recommended, with moderation for all fats, and avoid overheating any oil to prevent harmful compounds.
While small amounts can also be found in other vegetable oils, the concentration of carcinogenic glycidol in palm oil is 264 times higher than in olive oil, 24 times higher than in rapeseed oil and 15 times higher than in sunflower oil. The ratios are similar for 2-MCPD and 3-MCPD, as the graphs show.
About 90% of cancers are caused by environmental and lifestyle factors, not genetics, including smoking, poor diet (red meat, fried foods), alcohol, sun exposure, pollutants, infections, obesity, and inactivity; only 5–10% are due to inherited genetic defects, with most cancers arising from lifestyle-induced genetic mutations. Tobacco alone accounts for about a third of cancer deaths, while diet, obesity, and inactivity contribute significantly, with controllable factors being key to prevention.
Unfortunately, the cultivation of palm oil has been linked to deforestation. This is because palm oil plantations require large amounts of land to grow, which leads to clearing of forests, particularly in tropical areas.
While no single oil can directly “fight” cancer, certain oils contain compounds that may support the body's defenses against cancer progression. Extra virgin olive oil, for instance, is rich in polyphenols and monounsaturated fats, which have anti-inflammatory and antioxidant properties.
About 90% to 95% of melanoma skin cancers are caused by overexposure to ultraviolet (UV) radiation, primarily from the sun, but also from tanning beds, leading to DNA damage in skin cells and uncontrolled growth. This damage often results from short, intense periods of sun exposure and sunburn, especially during childhood, making sun protection crucial for prevention.
Previous studies demonstrated that a component found in some olive oils—oleocanthal—has this cancer-killing power. The new study demonstrates that olive oils rich in oleocanthal are powerful enough to kill cancer cells, while oleocanthal-poor olive oils are not.
McDonald's leads in palm oil use but not in commitments
Despite signing on to the non-binding New York Declaration on Forests in September reiterating the global importance of forests, McDonald's palm oil policies do not protect forests.
You should limit your intake of palm oil, which is high in saturated fat that can raise your heart disease risk. Palm oil contains antioxidants and can help treat vitamin A deficiency if you consume it in moderation.
Cervical cancer is one of the most preventable cancers thanks to the HPV vaccine. HPV, or the human papillomavirus, causes 99% of all cervical cancers. The HPV vaccine, which is given in 2 doses, targets 9 different types of the virus.
The number one preventable cause of cancer globally is tobacco use, including smoking and secondhand smoke, responsible for about one-third of cancer deaths and linked to many cancer types, followed by factors like unhealthy diet, inactivity, alcohol, obesity, and infections. While genetics and radiation also play roles, tobacco is the leading avoidable risk factor, making living smoke-free the best way to reduce risk.
Lung and bronchial cancer causes more deaths in the U.S. than any other type of cancer in both men and women.
But while it's not considered as unhealthy as trans fats, palm oil is 50% saturated fat. Saturated fat is often linked to heart disease. Palm oil has long been used in traditional medicine to treat everything from backaches to malaria. Some research has indicated that palm oil might have certain health benefits.
Exploring sustainable alternatives to palm oil in personal care products is crucial in reducing the environmental impact of our everyday choices. Shea butter, coconut oil, olive oil, babassu oil, and torula oil, are just a few of the viable options available.
The palm oil is easily digested and absorbed by human body. Its savory taste that enhances the taste of foods (palatability) and its important nutritional content have made it popular in many countries (Calloway and Kurtz, 1956).
When choosing a cooking oil, it's best to choose an oil high in poly and/or mono-unsaturated fats, which are heart-healthy fats derived foods such as olives, seeds, nuts and vegetables. Olive oil, which is high in monounsaturated fats, is a particularly beneficial choice for heart health.
The oils which should be avoided for cooking are oils like soybean, corn, canola, sunflower, and safflower. These oils have unstable fats and will decimate the nutritional properties of your food.
In terms of health benefits, canola oil is healthier than palm oil as it is higher in vitamin K, vitamin E, monounsaturated and polyunsaturated fats. Moreover, canola oil is lower in saturated fats (considered unhealthy fats).
Kentucky Fried Chicken had the latter in mind when selecting which vegetable oil it would fry its famous chicken in. As of 2007, KFC uses low-linolenic soybean oil for all of its frying needs. Different from typical hydrogenated soybean oil, the low-linolenic variety has less linolenic acid.
We use palm oil - an edible vegetable oil derived from the fruit of oil palm trees - in a number of our products. It's a versatile and highly efficient ingredient, requiring less land for production than any other oilseed crop (including soy, sunflower, rapeseed or coconut).
In the BURGER KING® system, palm oil is used in two ways—as frying oil in the Asia/Pacific region and as a minor ingredient in baked goods globally. Virtually all of our vendors who produce BKC's frying oils and baked goods source palm oil from suppliers who are members of the Roundtable on Sustainable Palm Oil (RSPO).
People are taking olive oil before bed for potential benefits like improved digestion, better sleep (by boosting melatonin/serotonin), reduced inflammation, heart health, and promoting satiety for weight management, leveraging its healthy fats and polyphenols. It's a growing wellness trend, particularly in Mediterranean cultures, to enhance overall vitality and support natural bodily repair overnight.
What cancers have the highest survival rates?
Cardiologists overwhelmingly view olive oil, especially extra virgin, as a heart-healthy fat, a cornerstone of the Mediterranean diet, linked to lower cardiovascular disease risk and mortality due to its monounsaturated fats and antioxidants that improve cholesterol, blood pressure, and inflammation. They recommend using it as a primary cooking/dressing oil, replacing less healthy fats like butter or margarine, and consuming it in moderation as part of a balanced diet rich in whole foods.
