Is palm oil harmful to health and does it offer any nutritional advantages?
Palm Oil: Separating Facts from Myths
Palm oil, derived from the fruit of the oil palm tree, has been a subject of debate due to concerns about its impact on health. Let's sift through the rumors and reveal the truth.
Is Palm Oil Bad for Your Health?
A 2020 review affirmed that incorporating palm oil into your diet in moderation, as part of a balanced diet, doesn't pose known health risks. Although palm oil contains a decent amount of saturated fat, consuming it in moderation shouldn't increase your risk of heart disease.
A 13.6-gram (g) tablespoon of palm oil equates to 13.6 g of fat, out of which 6.7 g is saturated fat. Saturated fats are known to elevate cholesterol levels; however, research indicates that palm oil may offer certain benefits to our heart health.
Intriguingly, research suggests that palm oil may help modulate blood cholesterol levels. A 2021 review explored the influence of palmitic acid on cholesterol levels. Palmitic acid, found in both animals and plants, including palm oil, demonstrated that palmitic acid from vegetable sources, like palm oil, had a less significant impact on blood cholesterol levels than palmitic acid derived from animal sources. Further, this review revealed that a chemical compound in palm oil called tocotrienols can significantly lower blood cholesterol levels by up to 38%.
While some studies are reassuring, the jury is still out, and more research is needed to fully understand palm oil's impact on heart health.
Health Benefits of Palm Oil?
Red palm oil boasts a higher concentration of antioxidants and micronutrients, which makes it a healthier option compared to its refined counterpart. Key nutrients found in red palm oil include:
- Carotenoids, essential for synthesizing Vitamin A
- Tocotrienols and Tocopherols, various forms of Vitamin E
- Plant Sterols, aids in reducing cholesterol levels
- Phospholipids, fundamental for cell structure and function
- Squalene, beneficial for skin health
Nutritional Information of Palm Oil
According to the United States Department of Agriculture (USDA), one 13.6g tablespoon of palm oil offers:
- 120 calories
- 503 kilojoules (KJ) of energy
- 13.6g of fat
- 6.7g saturated fat
- 5.03g monounsaturated fat
- 1.26g polyunsaturated fat
- 2.16 milligrams (mg) Vitamin E
- 1.09 micrograms (μg) Vitamin K
Environmental Impact and Considerations
The palm oil industry has come under Fire for its role in large-scale deforestation, habitat destruction for endangered species, and contributing to global climate change. To make ethical choices, seek out palm oil and palm oil products certified by the Roundtable on Sustainable Palm Oil (RSPO). This certification ensures that growers and manufacturers follow appropriate sustainability practices, such as adhering to robust policies against deforestation and human rights abuses, maintaining transparency in their sourcing, and enforcing the use of certified palm oil across their operations worldwide.
In conclusion, while palm oil offers specific health benefits, its high saturated fat content raises concerns. Moderation is key when incorporating palm oil into your diet. Furthermore, the integral role of palm oil in environmental degradation mandates ethical decisions when selecting palm oil and related products. As always, consult with your healthcare provider before making any significant changes to your diet.

Scientific Evidence on Health Effects of Red and White Palm Oil
Palm oil, which includes both red and white varieties, has been studied extensively for its health effects, particularly regarding cholesterol levels and cardiovascular disease risk.
Red Palm Oil
- Nutritional Content: Red palm oil is brimming with essential nutrients such as beta-carotene (a type of carotenoid), gamma-tocopherol (a type of Vitamin E), and phytoene (a type of carotenoid). These compounds boast powerful antioxidant properties.
- Health Benefits: Studies have suggested that red palm oil may support cognitive function, reducing oxidative stress, and inflammation, thus improving overall brain health. Preliminary trials have demonstrated enhanced cognitive performance, particularly in memory and attention tasks, in human subjects [1].
White Palm Oil
- Fatty Acid Composition: White palm oil, similar to all palm oil, is high in saturated fats (approximately 50%), primarily palmitic acid. It also contains monounsaturated fatty acids, such as oleic acid, and polyunsaturated fatty acids, such as linoleic acid [4].
- Impact on Cholesterol and Cardiovascular Disease:
- Saturated Fat Content: Plentiful intake of saturated fats can contribute to increasing levels of unhealthy low-density lipoprotein (LDL) cholesterol and raise the risk of cardiovascular disease [4].
- Mixed Evidence: Recent meta-analyses have found no significant association between saturated fat intake (including from palm oil) and increased cardiovascular disease risk. However, some studies and health organizations recommend reducing saturated fat intake in favor of unsaturated fats [4][5].
- Cardiovascular Effects: While some findings indicate that palm oil might not be as harmful as once perceived, especially when consumed as part of a balanced diet [5], there remains ongoing debate, with more research needed to thoroughly understand its impact on cardiovascular health [4].
In the 2020 review, it was affirmed that consuming palm oil in moderation, as part of a balanced diet, doesn't pose known health risks, despite its saturated fat content.A 2021 review explored the influence of palmitic acid on cholesterol levels, suggesting that palmitic acid from vegetable sources, like palm oil, had a less significant impact on blood cholesterol levels than palmitic acid derived from animal sources.Red palm oil, richer in antioxidants and micronutrients, offers nutritional benefits such as carotenoids, tocotrienols, plant sterols, phospholipids, and squalene.According to the USDA, a 13.6g tablespoon of palm oil offers 120 calories, 13.6g of fat, and 2.16mg of Vitamin E.The palm oil industry has been criticized for its role in large-scale deforestation, habitat destruction, and contributing to climate change.Consulting with a healthcare provider is always advisable before making any significant changes to one's diet.In addition to health effects, the scientific evidence on the impact of red and white palm oil on cholesterol levels, cardiovascular disease risk, cognitive function, and other medical conditions is an ongoing area of study in nutrition, medical-conditions, and environmental-science.
