Extra virgin olive oil is known to contain a bit more as far as antioxidants in the final product. But if you look at the actual levels, they are still basically nothing compared to antioxidant-rich fruits or vegetables. All refined vegetable oils contain a small amount of trans fat, which is indeed the most harmful fat of all. This trans fat is created in the deodorizing process. As long as the total trans fat is less than 0.
Canola oil has been shown to actually contain 1. Some of the omega-3 and omega-6 fats are converted to trans fat in the deodorizing process. So there is no intake of trans fat without some potential adverse effects. So in that sense, it would seem best to eat no refined oils. But is this actually a major concern? He cites a study showing that canola oil, for instance, was part of a very successful heart disease reduction study.
One thing Dr. Michael Greger often points out is that trans fat is also naturally found in meat and dairy products. And that would probably be the priority before eliminating the small amount in processed vegetable oils. These are the partially hydrogenated oils. I wrote about these a bit in my post about vegetable shortening Crisco.
Partially hydrogenated oils are now being banned in more and more parts of the world. By January of , all food manufacturers were required to stop adding these oils to foods. The World Health Organization has called to eliminate all uses of partially hydrogenated oils, globally, by But I find some of these articles about partially hydrogenated oils to be misleading.
Other sources of trans fats—like meat and the small amounts found in other processed vegetable oil—are not being banned. If you want to avoid consuming those remaining sources of trans fat, it still takes your own diligence. Caldwell Esselstyn Jr. In the video below, he concisely explains why, especially for those fighting heart disease, oil should not be on the menu—not even olive oil. He cites studies on:. Vegetable oils have also been shown to impair the function of endothelial cells and flow-mediated dilation FMD in your arteries following a meal.
There have been long-term studies showing that heart disease patients eating monounsaturated fat like olive oil had just as much disease progression as those eating saturated fat from animals. Oil is generally considered vegan. Most oils do not contain animal products. However, vegans eating a whole-food plant-based diet may choose to limit or completely avoid some or all oils for health reasons.
So, there are reasons to be concerned about eating too much of any processed oil. That said, there are still better oils, relatively speaking. In Dr. Where does he rank the various oils on this scale?
He ranks all vegetable oils as red-light foods except for extra-virgin olive oil, which he ranks as a yellow-light food. EVOO is one of the oils that is also championed by the paleo and keto folks. Sometimes I like to cross-compare to see what the vegan gurus and the paleo gurus actually agree on—because they disagree about so much!
EVOO is high in monounsaturated fat one of the healthier kinds , and it contains some antioxidants like vitamin E, as well.
That said, olive oil is still shown to increase triglycerides in the blood and impair endothelial function for a time after eating it. So, olive oil not a full-on health food. Avocado oil is another one of the oils rich in monounsaturated fat —it has a similar fat profile as olive oil. Used in both prepackaged foods and in many restaurants around the world, these two examples of lard products continue to be utilized in the preparation of many time-honored recipes, despite the availability of products considered to be healthier for human consumption.
While the basic substance of both types of lard is all the same, there are some key differences in the composition of hydrogenated and partially hydrogenated versions. Lard in all forms is simply pig fat. For centuries, lard was the cooking fat of choice for many different types of cuisine. In some instances, lard was also served and used as a topping for hot sections of bread, in a manner very similar to butter or margarine.
During the 20th century, the use of lard began to decrease as scientific research uncovered the health risks associated with the consumption of saturated fats such as lard products. However, the rich flavor that lard often brings to a recipe continues to make it the cooking fat of choice for many people in different cultures.
Today, lard is usually made available as both partially hydrogenated and hydrogenated products. Deconstructing Peanut Butter Most peanut butter sold in the U. There is a small amount of naturally occurring saturated fat in peanut butter 3 grams.
If your natural peanut butter separates, this is the oil that is usually found floating above the peanut butter. You can stir it back in and store your peanut butter upside down or in the fridge to reduce this.
Palm oil is a tropical oil that is solid at room temperature, therefore it is effective at helping reduce separation at room temperature. It is higher in saturated fat, which is why it is solid at room temperature, adding about 1. This oil was used to replace partially hydrogenated fats when research showed that trans fats, which are found in partially hydrogenated fats, were unhealthy.
Hydrogenated fats are fats that are liquid at room temperature and have been altered to be more solid at room temperature. Importantly, fully hydrogenating fats does not create harmful trans fats yet yields a fat that helps improve shelf-stability and prevents oil separation Hinrichsen, These fats add a small amount of saturated fat to peanut butter when they are part of the formulation. Like the addition of palm oil, adding hydrogenated fats increases the saturated fat in peanut butter by about 1.
Bottom Line The bottom line is that peanut butter is a delicious and nutritious food that comes in a variety of formulations to meet every preference.
