Is consumption of palm oil detrimental to health and does it deliver any nutritional advantages?
Palm oil, derived from the fruit of the oil palm tree, has faced scrutiny over potential health risks due to its high fat content and impact on cholesterol levels. However, studies suggest that consuming palm oil as part of a balanced diet poses no known health risks.
The oil comes in two main forms: red and white. White palm oil undergoes refinement, bleaching, and deodorization, resulting in lower levels of nutrients like beta carotene and vitamin E. Red palm oil, conversely, contains a higher concentration of antioxidants and micronutrients, making it the healthier option.
Recent research has examined palm oil's impact on cardiovascular health, often focusing on the oil's saturated fat content. Consuming a tablespoon of palm oil contains 13.6 grams of fat, 6.7 grams of which are saturated. However, some studies suggest that palm oil may have beneficial effects on blood cholesterol levels, with one review suggesting that it has less impact on cholesterol and LDL ("bad") cholesterol than saturated fat from animal sources. Another study found that a chemical compound in palm oil called tocotrienols lowered blood cholesterol levels by 7% to 38%.
Although some studies have raised concerns about the link between palm oil consumption and cardiovascular disease, a review from 2020 found no evidence supporting this association. Nevertheless, researchers have called for further research to better understand the relationship between the two variables.
While palm oil may have some health benefits, it is important to consider its nutritional information. A tablespoon of palm oil contains 120 calories, 13.6 grams of fat, 6.7 grams of saturated fat, 5.03 grams of monounsaturated fat, 1.26 grams of polyunsaturated fat, 2.16 milligrams of vitamin E, and 1.09 micrograms of vitamin K.
Environmental impact is another factor to consider when choosing palm oil and palm oil products. The palm oil industry has been linked to large-scale deforestation, habitat destruction for critically endangered species, and climate change. To minimize these impacts, the World Wildlife Federation advises consumers to look for palm oil and palm oil products featuring the Roundtable on Sustainable Palm Oil (RSPO) certification, which indicates adherence to sustainability practices such as robust policies to remove deforestation and human rights abuses from the supply chain, transparency in sourcing and use, and buying and using certified palm oil across operations globally.
Palm oil is not a seed oil and should not be confused with palm kernel oil, which is derived from the kernel inside the palm fruit.
In conclusion, while palm oil contains a balance of saturated and unsaturated fats, clinical evidence suggests that it may have some benefits for cholesterol levels and heart health. When consumed in moderation and as part of a balanced diet, palm oil can be integrated into a dietary fat intake plan. However, environmental considerations and dietary guidelines should also be taken into account when choosing palm oil products. Consumers are encouraged to look for RSPO certification to ensure the most robust environmental and human rights practices are being followed. As always, individuals should consult their healthcare provider to determine the best dietary choices for their individual needs.
