Palm oil

Introduction

Coconut oil and palm oil are both edible, vegetable oils derived from palm fruits, that are also widely used in personal care. In this article, we will discuss how these oils are produced, and talk about their nutritional composition and impact on health, comparing them along the way.

Production

The initial substance in coconut oil production is, naturally, a coconut. After cracking the coconut, the white endosperm is removed and dried. This dried coconut meat, also known as copra, undergoes solvent extraction or is pressed with a special tool to attain the unrefined oil. To then produce refined oil the initial oil goes through more steps: it is mixed with agents, to change the texture of the oil, chemical solvents are added to remove free fatty acids. Later, this substance is filtered through clay and, finally, heated to remove the remaining scent from it.

Palm oil is primarily made from the African oil palm (Elaeis guineensis). Oil can be produced from both the palm fruit and the crushed kernel, however, kernel oil has different qualities compared with the palm fruit oil. First the palm fruits are steamed and pressed to remove the solids from the oil, then this oil is processed and refined to remove impurities from it. Later, this refined oil is fractionated into liquid and solid fats. Each fraction is used to produce various products.

Taste and Use

Vegetable oils are very versatile. They are used in numerous industries as ingredients in food, cosmetics and even as biofuels.

Coconut oil is predominantly used as a cooking oil, body and hair oil, and industrial oil. It is also used in the manufacture of sweets, margarine, as well as paints and pharmaceutical agents (1).

Palm oil is said to be in half of the products on supermarket shelves. You can find it in most foods, cosmetics and hygiene products.

Depending on the type of coconut oil, it can taste different. Unrefined coconut oil does have a taste of coconut, whereas refined coconut oil does not and therefore has a more neutral flavour.

The taste of palm oil is often described to be sweet, similar to carrots or neutral and mellow.

Varieties

Coconut oil comes in three forms, depending on the processing method: unrefined, also known as virgin or extra virgin, refined and partially hydrogenated. Unrefined coconut oil is simply made by pressing the oil out of the coconut meat. Based on the method, unrefined coconut oil can also be expeller-pressed or cold-pressed. This oil has a stronger coconut taste and scent, as well as a lower smoke point.

Refined coconut oil does not have a coconut flavour or odor, but has a higher smoke point, which makes this oil more appropriate for cooking with high heat.

Partially hydrogenated coconut oil is the most processed version of the three. The process of hydrogenating the oil turns the unsaturated fats into saturated fats, creating unhealthy trans fats along the way. This oil has a longer shelf life and a more solid form in room temperature.

You can find three common types of palm oil as well, but the difference mainly depends on which part of the palm the oil was made from. Oil derived from the palm fruit is simply named palm oil, while oil made from the palm seed or stone is called palm kernel oil. By further processing palm kernel oil, fractionated palm kernel oil is produced.

Nutrition

Depending on the level of processing and type of the oil, the nutritional composition may vary.

Macronutrients and Calories

Edible oils are overall not very diverse in nutrients. Coconut oil contains very little water, while palm oil is completely absent in water.

Coconut and palm oil have equal serving sizes: one tablespoon of oil weighting 13.6g.

Calories

Vegetable oils are very high in calories. Coconut and palm oil contain similar amounts of calories, however, coconut oil is a little higher.

One serving size of coconut oil contains 121 calories, while palm oil has 120.

Fats

Edible oils consist mostly of fats. Coconut oil consists of 99% fats, whereas palm oil is nearly 100% fat.

A serving size of coconut oil contains 13.5g of fats.

The fat in coconut oil consists of 91% saturated fatty acids. Next by portion is monounsaturated fat, and last, polyunsaturated fatty acids. 

Palm oil contains a lot more of monounsaturated and polyunsaturated fatty acids, however, saturated fat still makes up the majority.

The fat composition changes for partially hydrogenated oils, as poly- and monounsaturated fats turn into saturated fat. 

Protein and Carbohydrates

Coconut and palm oil contain no protein or carbohydrates.

Vitamins

Both oils contain only two vitamins: Vitamin K and vitamin E

Palm oil is much richer in both of these

Minerals

Coconut and palm oil contain only trace amounts of minerals as well. However, coconut oil is higher in iron and choline compared to palm oil. It also contains small amounts of zinc and calcium, whereas palm oil does not.

Glycemic Index

As both coconut oil and palm oil contain no carbohydrates, their glycemic indices are equal to 0.

Acidity

Raw coconut is alkaline, however, through heating and further processing coconut oil becomes acidic with an average pH of 3.5 to 5.5 (2).

Palm oil is also slightly acidic with a pH value of 6.34 on average (3).

Another way to look at the acidity of a food is by looking at the potential renal acid load (PRAL), which shows the capacity of the food to produce bases or acids.

The PRAL value for both coconut oil and palm oil is 0, making these oils neutral.

Weight Loss

Both coconut and palm oil are very high in calories, due to their high fat content. One tablespoon of these oils contains around 120 calories. 

Despite its high caloric value, coconut oil is often claimed to aid weight loss. Most research doesn't support the idea that coconut oil can lead to weight loss when used on it’s own. Coconut oil could increase high density lipoproteins and decrease the total cholesterol/ high density lipoprotein ratio in men with obesity, when used as a part of a low calorie, balanced diet (4). However, many studies have concluded that there is not enough consistent evidence that coconut oil has beneficial effects on energy metabolism, satiety or weight loss (5, 6, 7).

Studies on the association between palm oil consumption and weight loss have not achieved significant results as well. There is also insufficient evidence to claim palm oil’s superior qualities over other vegetable oils in obesity management (8)

Health Impact

In this section, we will discuss what effects coconut oil and palm oil have on human health and how these effects compare to each other.

Health Benefits

Cardiovascular Health

One meta analysis concluded that although coconut oil increases high density lipoproteins (also known as “good” cholesterol), that effect was not enough to make up for the negative effects caused by coconut oil’s property of raising low density lipoproteins (“bad” cholesterol) (9). In contrast to this, another study found that daily consumption of moderate amounts of coconut oil raises high density lipoproteins and shows no significant harmful side effects (10).

Coconut oil also significantly increased total cholesterol and low density lipoprotein cholesterol concentrations compared with palm oil, as well as other vegetable oils, due to the high saturated fat content (9).

However, in comparison to animal oils, coconut oil demonstrated more favourable changes in blood lipid profile, lowering low density lipoproteins. Virgin coconut oil performed the best results (11).

Some research, carried out on animals, has concluded that coconut oil is associated with an improvement in antioxidant activity, lipid profile, blood pressure, blood sugar and abdominal body fat (12). These effects still have to be studied in humans.

Meta analyses on the topic of palm oil consumption have concluded that it does not have incremental risks for cardiovascular disease or cardiovascular disease related mortality (13, 14). 

Diabetes

Multiple studies have found that coconut oil, especially virgin coconut oil, may ameliorate lipid profiles in diabetes mellitus type 2 (15, 16), as well as support normal glucose homeostasis and modulate the immune response (17). Virgin coconut oil may also be used as a functional food to prevent the development of diet-induced insulin resistance and associated complications, potentially due to its antioxidant qualities (18).

Some studies show that substitution with red palm oil as an antioxidant may reduce blood glucose in diabetic patients (19, 20). However, others have not found significant effects of palm oil on biomarkers of glucose metabolism (21). 

Cancer

Coconut oil has expressed antiproliferative and pro-apoptotic responses in tumor cells (22). Virgin coconut oil, as well as processed and fractionated coconut oil, have shown anticancer activities, especially against liver and oral cancer (23). Moreover, virgin coconut oil consumption during chemotherapy may also improve quality of life for breast cancer patients (24).

As for palm oil consumption and cancer correlation, there is no evidence associating palm oil intake and a higher risk of cancer, incidence or mortality in humans (25).

Downsides and Risks

Cardiovascular Health

American Heart Association has found that due to high saturated fats, coconut oil raises low density lipoproteins, which can pose a risk for atherosclerotic cardiovascular diseases (9).

The use of repeatedly heated palm oil, as well as other oils, is also a predisposing factor of atherosclerosis and the consequent cardiovascular issues (26).

Environmental Issues

The widespread palm oil production can cause environmental hazards that negatively affect not only nature but also our health. Large-scale palm oil production leads to deforestation, not only destroying the habitats of endangered species, but also leading to an increase of greenhouse gases in the atmosphere, further contributing to climate change (27).

Summary

In summary, coconut oil and palm oil are both high calorie foods, consisting mostly of fats. Coconut oil is a little higher in calories, while palm oil contains a little more fats. Both completely lack protein and carbohydrates and are low in micronutrients. However, coconut oil is relatively richer in minerals, whilst palm oil contains more vitamin E and vitamin K.

Research suggests that palm oil is a healthier choice than coconut oil when it comes to cardiovascular health, due to a lower saturated fat content. Both can have positive effects for people with diabetes type 2.

Overall, these oils can be healthy when used in moderation and as part of a healthy diet.
