In May last year, the European Food Safety Authority (EFSA) assessed the risk to public health, in regards to contaminated substances.
EFSA help to regulate EU food safety, through scientific advice on any potential risks to consumers.
When vegetable oils and fats are refined at high temperatures (200°C), glycidyl fatty acid esters (GE), 3-monochloropropanediol (3-MCPD), and 2-monochloropropanedoil (2-MCPD) and their fatty acid esters, are formed.
This process is used during food processing, which means that when products are made in this way, they have a higher risk of having these three substances (EFSA, 2016). It was found that the highest level of these three substances were found in palm oil and palm fats. Therefore, foods that use a large quantity of the refined palm oil, will also contain higher levels of these glycidyl esters.
When we consume these glycidyl esters in products, they can be broken down and digested by the body to release glycidol and this is where problems arise.
EFSA had an expert panel (The Panel) look at the risk assessment of glycidyl esters if they are converted into glycidol. Dr Helle Knutsen, Chair of The Panel stated: “There is sufficient evidence that glycidol is genotoxic and carcinogenic, therefore the CONTAM (Contaminants in the Food Chain) Panel did not set a safe level for GE”. So essentially EFSA, will not even place a safe level at which it is ok to consume these products which contain glycidyl esters, due to the implication that they are carcinogenic and genotoxic, causing a potential health risk.
Carcinogenic is defined as any substance that has the potential to cause cancer to living tissues. They affect and damage our DNA, causing damage on a cellular level.
Some things that are included as carcinogenic are smoking; asbestos; processed meats; and charred food, especially meats, to name a few. This doesn’t mean that they are all equally dangerous in regards to their carcinogenic properties but that they all can cause cancer.
Genotoxic is where there is damage to a cell's genetic material, affecting its quality. Genotoxins are referred to as mutagens. These are agents which cause mutations within cells. These genotoxins can be carcinogenic, cancer-causing agents, mutagens, mutation-causing agents, or teratogens (causes malformation to an embryo), or birth defecting-causing agents (Shah, 2012).
Palm oil is a major contributor to 3-MCPD and 2-MCPD exposure for most individuals. However, it was found by The Panel that the levels of glycidyl esters in palm oils and fats have halved between 2010-2015, due to measures taken by producers in reducing exposure to these substances. However levels of 3-MCPD and its esters in vegetable oils have remained mostly unchanged over the last five years (EFSA, 2015). EFSA reported that further research was needed to fill in gaps and to help improve knowledge on the toxicity of these substances and the impact exposure may have on consumers.
So, recently in the news you may have seen that a well-known company has been impacted by this report from EFSA. Palm oil is also found within margarines, pastries and cakes to name a few and so many products which are processed, use palm oil within their recipes, even some that you wouldn’t have thought, including big name brands. (Independent, 2017).
The Panel at EFSA also picked up on the fact that infant milk formula contains glycidyl esters and that there is concern around the impact on infants’ health for those who are solely fed on these specific formulas, and what negative impact they could potentially have.
In Italy, the country’s biggest supermarket chain, called Coop, have, as a precaution, stopped selling a product because of this information. Coop is not the only retailer to have done this and there are several others who have joined in.
You'll mainly find this refined palm oil in processed foods, so by eating a fresh, healthy and balanced diet you should be able to steer clear of palm oil.
It’s not just us humans that are impacted by the effects of palm oil. It's also been a major cause of deforestation and impacts both the wildlife and those who live in the areas which they are now growing palm trees on.

.As our followers will no doubt know, we're fans of keeping things natural, where possible which is why we love this recipe for Chocolate Nut Butter. All you need is the ingredients and a good blender!
We also have a great recipe to make a Cacao Nut Butter, available here, which is vegan and gluten free.
Cacao Nut Butter – Vegan and Gluten Free
3 tbsp. Lucy Bee Cacao Powder/Drinking Chocolate
1 tsp. vanilla extract
1/4 tsp. Lucy Bee Cinnamon Powder
Preheat the oven to 180C, 350F, gas mark 4.
Cover a baking try with baking parchment, add the nuts and roast for 10 minutes.
Next, you need to remove most of the skins from the hazelnuts. This is done by placing the nuts in a clean kitchen towel and, holding the towel in one hand, rub the nuts together, through the towel, with your other hand.
Wrap the nuts in a kitchen towel to 'rub off' the nut skins
Place the nuts (minus the skins) into a blender and blend until oil is released and the nuts form a paste (this takes approximately 8-10 minutes, depending on your blender. You may need to stop halfway through and let the blender cool down).
Add Lucy Bee Cacao Powder/Lucy Bee Drinking Chocolate, the vanilla extract and Lucy Bee Cinnamon Powder and continue blending until smooth.
Unlike some shop-bought chocolate spreads, it won't go 'smooth smooth' because it still has some of the skins.
