Palm Oil Is in Everything, and It’s Hurting More Than the Orangutans
By Helen A. Lee
We cook with it. We bathe with it. We use it for mood lighting. Palm oil is an ingredient in processed foods, cosmetics, hygiene products, biofuels and candles; experts estimate it's found in 50 percent of the items on grocery store shelves. Inexpensive to produce, palm oil contains no trans fats, and has a high melting point, making it versatile and easy to spread. The result: increasing demand. In 1996, global production totaled 16 million metric tons. By 2017, it was 60.7 million.
But there's a problem. Palm oil may not cost much to produce, but it exacts a high price on the environment. And thanks to this often-invisible ingredient's complex international supply chain, efforts to reduce that impact are proving challenging.
From Virgin Forest to Grocery Store
The story of palm oil begins with clearing tropical rainforests and peatlands for plantations of oil palm trees, which thrive on warmth, sunlight, and copious rainfall. The trees — native to West Africa — produce clusters of orange-red fruit year-round, and can be harvested every 10–14 days when mature. For the most part, oil palms don't need much help, but some farms do use herbicides and insecticides. Oil palms produce 3.8 metric tons of oil per hectare annually — eight times as much as soybeans (.5 t/ha), and almost five times the yield of canola (.8 t/ha).
Palm fruit contains oil in its flesh (palm oil), and its seed (palm kernel oil). At diesel-powered mills, fruit and kernels are pressed to extract oil. The next stop is often a refinery, where bleaching improves the oil's color, deodorization reduces its smell, and "fractionation" can create different oils suited for different purposes. Then, the oil is shipped all over the world.
The U.S. Department of Agriculture says palm oil is the most consumed oil in the world, and its non-food uses are also increasing. India, China, Europe and Pakistan are the top importers, collectively using more than half of the global supply. In Asia, it's used in home cooking. In Europe and the U.S., most demand comes from manufacturers for everything from Oreos to toothpaste. You can find it in Silk soy milk, Secret deodorant, Nutella, Jergens lotion, instant noodles and Girl Scout cookies.
Palm Oil and Environmental Devastation
Malaysian and Indonesian plantations make up about 85 percent of the industry, with Guatemala, Benin and Thailand among the other top producers. Areas with low wages and abundant labor often welcome palm plantations — despite the industry's history of slavery, child labor, and land-theft — because of their potential to lift workers out of poverty.
Around the world, the business of palm oil harms the environment. During conventional cultivation, forests are cleared for plantations, bringing biodiversity loss, human-wildlife conflict, and habitat destruction affecting many species, notably the orangutan. A recent International Union for Conservation of Nature report notes that 50% of all deforestation on Borneo between 2005 and 2015 was driven by palm oil development.
This deforestation also contributes to climate change; the conversion of forests to palm oil plantations releases carbon dioxide that had been absorbed by old-growth forests. The Union of Concerned Scientists estimated in 2013 that 10 percent of global greenhouse gas emissions come from tropical deforestation.
These impacts have proven hard to combat, in part because palm oil is rarely the end commodity. Richard Zimmerman, executive director of New York-based non-profit Orangutan Outreach, calls it a "pervasive yet hidden" problem. Given all the chemicals, sugars, fats, and allergens shoppers are already trying to avoid, he said, "Palm oil is low on the list, if it's even on the list."
Palm oil and its derivatives appear under a multitude of monikers, from "palm kernel oil" and "partially hydrogenated palm oil" to "sodium lauryl sulfate" and "glyceryl stearate." Other names, according to the Rainforest Action Network, include "stearic acid," anything that includes "palmitate," and "elaesis guineensis" (the oil palm's Latin name). Try finding products in your grocery store without these. Not that all these terms always mean palm oil — some are occasionally derived from other oils. But companies likely can't guarantee that, and there's no way of knowing from reading a package.
So how do we change things? One group trying to answer that question is the Roundtable on Sustainable Palm Oil (RSPO), a 4,000-member-strong industry non-profit. Its approach includes offering financial incentives to stakeholders along the supply chain in return for implementing best practices.
RSPO members must demonstrate that plantation land was purchased, not stolen, and that they offer safe conditions for workers. The RSPO prohibits clearing primary (never-logged) forests and imposes requirements like: obtaining free, prior, and informed consent from locals for new plantings; analyzing and protecting fragile soils and areas of high-conservation value; and mitigating carbon impacts in place.
But right now, only about 20 percent of palm oil is RSPO-certified, and critics think the group's approach still doesn't go far enough. Greenpeace's Senior Palm Oil Campaigner Diana Ruiz said investigations show that brands shift responsibility for palm oil sourcing problems onto traders, and traders don't enforce on their end. "Once you get … all the way to the grower, there is no monitoring being done," she says — and no good way to address violations.
Beyond the produce section, palm oil can be found in almost everything in your grocery store, from from Oreos to toothpaste and beyond.
The Future of Palm Oil
Palm oil has a long supply chain, which makes reducing its use complex. "Historically, companies have not paid attention to what happens at the farm level, because [palm oil] is a secondary ingredient," said Neil Blomquist, a spokesperson for the education and advocacy group Palm Done Right.
That may be changing, as palm oil gets more publicity. Still, places where palm grows see a clear economic boom from the industry, and there's always a market for cheap consumables.
"It's a difficult industry to regulate for that reason," Blomquist said. "There's been a growing demand for palm oil, the lowest-cost oil that can be produced. So, increasing demand with an increasing population in the world is really what's driving the problems… with more and more rainforest being destroyed."
Ending the use of palm oil may not be the answer. "Going to a boycott could cause more problems," said Dan Strechay, the RSPO's US outreach and engagement representative. "Because if we don't buy palm oil — or ingredients that contain palm oil — it's not like we snap our fingers and we have additional materials to put in. Something else has to be grown to replace it, and other oil seeds may require more land."
But continuing as we are means ignoring the true costs of palm oil: to the environment and people living in palm-oil-producing areas. Said Zimmerman,"If the humans aren't doing well, the orangutans are not going to do well."
So, what do we do now? Eating fewer processed foods, buying locally, and otherwise voting with your dollars is a start. Keeping companies accountable for meeting their stated deadlines around sourcing sustainable palm oil is also key.
Ruiz says the next step is asking suppliers and traders to create more transparency around their reporting, and the public can help. "We have huge influence over these brands," she said. "The key here is to use that buying power we have as consumers and demand that companies do better."

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
