Exploring the Controversy: Is Palm Oil Harmful or Beneficial for Health?
Let's dive into the lowdown on palm oil, shall we? This stuff comes from that oil palm tree you might've heard of, known for its high-fat content. Folks have waved red flags, stating it could jack up cholesterol levels and increase the risk of cardiovascular disease (CVD). However, the scientific community's got their backs turned on that theory, as there's not much proof supporting it.
There are two main types of palm oil: red and white. The white kind's been refined, whitened, and deodorized, resulting in fewer micronutrients like beta carotenes, vitamin E, and the like. That's why people usually consider red palm oil the healthier pick.
Now, let's answer the million-dollar question: Is palm oil bad for your health?
A 2020 review tells us that consuming palm oil in moderation, as part of a balanced diet, doesn't seem to carry known health risks. People might worry about the saturated fat content and how it could hurt their health. Well, a 13.6-gram tablespoon of palm oil packs 13.6 grams of fat, with 6.7 grams coming from saturated fat. Saturated fats typically raise cholesterol levels, which could increase the risk of heart disease.
But guess what? Research suggests that palm oil might actually have some benefits when it comes to cholesterol levels. A 2021 review looked at the impact of palmitic acid (a saturated fatty acid found in palm oil and such) on cholesterol levels. They found that palmitic acid from palm oil and other plant-based sources had less impact on blood cholesterol levels and "bad cholesterol" (LDL) than palmitic acid from animal sources. Not only that, they discovered that a chemical compound in palm oil called tocotrienols could lower blood cholesterol levels by 7% to 38%!
An earlier review also couldn't find any evidence backing a connection between palm oil consumption and CVD. However, they pointed out some difficulties in quantifying the true association between the two variables and expressed the need for further research.
So, are there any health benefits to consuming palm oil?
As a 2021 review states, there are two primary types of palm oil: red palm oil and "refined, bleached, deodorized" (RBD) palm oil, also known as "white" palm oil. Red palm oil is chock-full of antioxidants and micronutrients like:
- carotenoids, which help the body produce vitamin A
- tocopherols and tocotrienols, types of vitamin E
- plant sterols, which help lower cholesterol levels
- phospholipids, crucial for cell structure and function
- squalene, which is great for the skin
The refinement process utilized in creating RBD palm oil leads to lower quantities of carotenoids, vitamin E, and sterols. Consequently, RBD palm oil comes with fewer health benefits than red palm oil.
Here's the nutritional rundown for one 13.6-gram tablespoon of palm oil:
- 120 calories
- 503 kilojoules of energy
- 13.6 grams of fat (6.7 grams of saturated fat, 5.03 grams of monounsaturated fat, and 1.26 grams of polyunsaturated fat)
- 2.16 milligrams of vitamin E
- 1.09 micrograms of vitamin K
Now, let's talk about the environmental impact of palm oil and some things to keep in mind when purchasing palm oil products.
The World Wildlife Federation (WWF) explains that palm oil is an efficient, high-yield crop that provides a decent income for growers and peasants. However, the palm oil industry is wreaking havoc, causing large-scale deforestation, destroying habitats for critically endangered species, and contributing to climate change all over the planet. Therefore, the WWF encourages individuals to make ethical choices when it comes to purchasing palm oil.
The WWF suggests looking for palm oil and palm oil products featuring the Roundtable on Sustainable Palm Oil (RSPO) certification. This global certification indicates that palm oil producers and manufacturers have stuck to the following sustainability practices:
- Devising strong policies to remove deforestation and human rights abuses from the supply chain.
- Achieving transparency in the sourcing and use of palm oil.
- Adopting certified palm oil across their operations worldwide.
Frequently asked questions:
- Why is palm oil not considered a seed oil? Palm oil doesn't come from a seed; it derives from the fruit of the oil palm tree. It's not the same as palm kernel oil, which comes from inside the fruit.
- The debate surrounding palm oil's impact on nutrition continues, with some claiming it may elevate cholesterol levels and risks of chronic-diseases like cardiovascular-health issues.
- However, the scientific-community largely discredits these warnings, citing lack of substantial evidence in support.
- Palm oil is categorized into two main variants: red and white, with white oil undergoing refinement, bleaching, and deodorization to decrease micronutrient content.
- Red palm oil, richer in nutrients, is often deemed healthier due to its high concentration of antioxidants, vitamins, and plant sterols.
- Consumption of palm oil within moderation, as part of a balanced diet, may not pose any known health risks, according to a 2020 review.
- Most controversy revolves around palm oil's saturated fat content, and fears it may adversely affect cardiovascular-health and other-nutrition factors.
- A 2021 review, however, revealed that palmitic acid from plant-based sources such as palm oil had less impact on cholesterol levels compared to animal sources.
- Additionally, it was uncovered that a chemical-compound in palm oil known as tocotrienols could reduce blood cholesterol levels by 7% to 38%.
- Earlier reviews also failed to draw a correlation between palm oil consumption and chronic-diseases, expressing the need for more research to quantify any association accurately.
- The health benefits of palm oil consumption may include lower cholesterol levels, enhanced by antioxidants, vitamins, and plant sterols found in red palm oil.
- Refined, bleached, deodorized (RBD) palm oil, also known as white palm oil, contains fewer health benefits due to reduced micronutrient levels.
- One 13.6-gram tablespoon of palm oil offers 120 calories, 503 kilojoules of energy, and a blend of fatty acids and essential vitamins.
- The environmental-impact of palm oil cannot be overlooked, with the palm-oil industry implicated in large-scale deforestation, habitat destruction, and climate-change concerns.
- Organizations like the World Wildlife Federation (WWF) advocate for conscious-consumption and responsible buying decisions, prioritizing products with Roundtable on Sustainable Palm Oil (RSPO) certification.
- RSPO certification signifies that producers have committed to eradicating deforestation, addressing human-rights abuses, and promoting transparency within their supply chain.
