Is palm oil detrimental to health and does it offer any nutritional advantages?

So, is palm oil the devil in your pantry or just a misunderstood fruit of the oil palm tree? Let's dig a little deeper.

Here's the scoop: there are two main types of palm oil, red and white. Red palm oil, having undergone fewer processing steps, maintains its nutritional robustness with a higher concentration of antioxidants, vitamins, and plant sterols. On the other hand, white or "refined, bleached, deodorized" (RBD) palm oil loses much of these beneficial nutrients during the refinement process.

Some folks might be concerned about the high saturated fat content in palm oil, as it may contribute to raising cholesterol levels and increasing the risk of cardiovascular disease (CVD). However, the current scientific consensus on palm oil's health effects, particularly its impact on cholesterol levels and heart disease risk, is mixed and evolving.

A 2020 review found that consuming palm oil in moderation and as part of a balanced diet does not present known health risks. Interestingly, the research surrounding the consumption of palm oil and its effect on blood cholesterol levels suggests that palm oil may have some benefits. For instance, a 2021 review discovered that palmitic acid, a common saturated fatty acid in palm oil, has less impact on blood cholesterol levels and "bad cholesterol" than palmitic acid from animal sources. Moreover, the review highlighted that a chemical compound in palm oil called tocotrienols actually helps lower blood cholesterol levels by 7% to 38%.

However, other studies have yielded more cautionary results. An earlier review found no evidence to support an association between palm oil consumption and CVD. But the reviewers also pointed out difficulties in quantifying the true association between the two variables, necessitating further research in this area.

When it comes to health benefits, red palm oil boasts a rich nutritional profile. It's packed with beneficial compounds like carotenoids, which the body uses to synthesize vitamin A, tocopherols and tocotrienols (types of vitamin E), plant sterols, phospholipids, and squalene, which has benefits for the skin. On the other hand, RBD palm oil contains fewer of these beneficial nutrients due to the refinement process.

Now, let's not forget about the environmental impact. The palm oil industry is causing widespread deforestation, threatening critically endangered species, and contributing to climate change. To make ethical choices when purchasing palm oil, the World Wildlife Federation (WWF) advises looking for products featuring the Roundtable on Sustainable Palm Oil (RSPO) certification. This certification indicates that palm oil growers and manufacturers have adhered to robust environmental and human rights policies.

In conclusion, while palm oil can be part of a balanced diet when consumed in moderation, its high saturated fat content necessitates careful consideration of overall dietary fat intake to manage heart health. Furthermore, it's essential to prioritize sustainable, responsibly-sourced palm oil options to minimize the industry's harmful environmental footprint.
