Palm oil provides several health benefits. On the other hand, it may be risk to heart health. There are also environmental concerns related to the increase in its production.

It is widely used in food products, cosmetics and as a biofuel. However, its production has raised concerns due to its environmental impact, particularly deforestation and habitat destruction for wildlife. In this article, we will explore what palm oil is, its uses and whether it has any health benefits.
What is Palm Oil?
Palm oil is extracted from the fruit of oil palm trees primarily the African oil palm (Elaeis guineensis) and to a lesser extent the American oil palm (Elaeis oleifera). The oil palm tree is native to West Africa but it is now grown extensively in tropical regions around the world, including Southeast Asia and South America.
Unrefined vs. refined palm oil
Unrefined palm oil
Processing: Unrefined palm oil is extracted from the fruit of the oil palm tree through a simple mechanical process, often using traditional methods. It is not subjected to refining or chemical treatments.
Color and Flavor: Unrefined palm oil retains its natural red color due to the presence of carotenoids which are natural pigments with antioxidant properties. It has a distinct flavor and aroma, often described as nutty or earthy.
Nutritional Content: Unrefined palm oil contains higher levels of antioxidants such as carotenoids and tocopherols (forms of vitamin E), compared to refined palm oil. It also retains more of its natural nutrients during processing.
Smoke Point: Unrefined palm oil has a lower smoke point compared to refined palm oil, making it less suitable for high-temperature cooking.
Refined Palm Oil:
Processing: Refined palm oil undergoes a more extensive refining process, which involves physical and chemical treatments to remove impurities, odor and color. This process may include bleaching and deodorization to produce a neutral flavor and aroma.
Color and Flavor: Refined palm oil has a lighter color and a neutral flavor and aroma compared to unrefined palm oil. The refining process removes the natural pigments and flavors present in unrefined palm oil.
Nutritional Content: Refined palm oil may have lower levels of antioxidants and other natural compounds compared to unrefined palm oil due to the refining process. Some nutrients and beneficial compounds may be lost during refining.
Smoke Point: Refined palm oil has a higher smoke point compared to unrefined palm oil, making it more suitable for high-temperature cooking methods such as frying.
How is it used?
Palm oil both unrefined and refined is used in a variety of ways in cooking, food processing and other industries. Here are some common uses for both types of palm oil:
Unrefined (Red) Palm Oil:
Cooking: Unrefined palm oil is widely used for cooking in regions where it is produced, such as West Africa and parts of Southeast Asia. It is often used in traditional dishes to add flavor and color to the food.
Food Preparation: Unrefined palm oil is used in the preparation of sauces, soups, stews and curries, where its distinct flavor and color are desired.
Nutritional Supplements: Due to its high content of antioxidants, unrefined palm oil is sometimes used as a nutritional supplement in the form of capsules or added to health drinks.
Refined Palm Oil:
Cooking: Refined palm oil is commonly used for cooking in commercial food production and in households where a neutral flavor and higher smoke point are preferred. It is suitable for frying, baking, and other high-temperature cooking methods.
Food Processing: Refined palm oil is used extensively in the food industry for the production of processed foods, including snacks, baked goods, margarine and non-dairy creamers. Its neutral flavor and stability make it a versatile ingredient in food processing.
Cosmetics and Personal Care Products: Refined palm oil and its derivatives are used in the production of cosmetics, soaps, shampoos, lotions and other personal care products due to their emollient properties.
Biofuel: Refined palm oil is used as a feedstock for the production of biodiesel, a renewable and environmentally friendly alternative to conventional diesel fuel.
Palm oil nutrition
Here are the approximate nutritional values for 1 tablespoon (14 grams) of palm oil:
Calories: 120
Total Fat: 14 grams
Saturated Fat: 7 grams
Monounsaturated Fat: 5 grams
Polyunsaturated Fat: 1.5 grams
Vitamin E: 1.9 mg (10% of the Daily Value)
Vitamin K: 8.1 mcg (10% of the Daily Value)
Keep in mind that these values are approximate and can vary slightly depending on the specific product and its processing. Palm oil is high in saturated fat so it should be consumed in moderation as part of a balanced diet.
Benefits of palm oil
Palm oil contains several compounds that may offer potential health benefits although it’s important to consume it in moderation due to its high saturated fat content. Here are some potential benefits associated with palm oil:
Antioxidant Properties: Palm oil contains tocotrienols and tocopherols which are forms of vitamin E with antioxidant properties. Antioxidants help protect cells from damage caused by free radicals, which are unstable molecules that can contribute to aging and various diseases.
Nutrient Absorption: The fat in palm oil may aid in the absorption of fat-soluble nutrients like vitamins A, D, E and K. These vitamins play crucial roles in various bodily functions, including vision, bone health, immune function and blood clotting.
Heart Health: Some studies suggest that the tocotrienols found in palm oil may have potential benefits for heart health. Research indicates that tocotrienols may help reduce cholesterol levels and improve overall cardiovascular health although more studies are needed to confirm these effects.
Skin Health: Vitamin E, which is present in palm oil is known for its role in skin health. It is an antioxidant that can help protect the skin from damage caused by UV rays and free radicals, potentially reducing the signs of aging and promoting overall skin health.
Nutritional Benefits: Palm oil contains a balanced ratio of saturated and unsaturated fats, which makes it suitable for cooking purposes. It also contains some essential fatty acids such as linoleic acid which are important for overall health.
It’s important to note that while palm oil may offer some potential health benefits it is high in saturated fat which, when consumed in excess can increase LDL cholesterol levels and the risk of heart disease. Therefore, it should be consumed in moderation as part of a balanced diet and individuals with existing heart conditions or high cholesterol levels should consult with a healthcare professional before consuming palm oil regularly.
