Chocolate sauce containing palm oil can cause cancer? You need to know the truth.
A while ago, China’s WeChat went viral about a brand of chocolate sauce products that caused cancer for the following reasons:
Chocolate sauce contains palm oil, which produces more carcinogens glycidyl fatty acid ester (GE) and chloropropanol ester than other vegetable oils, which promote and worsen tumor growth and increase cancer risk.
The article also said that “palm oil prices are much lower than other vegetable oils”, as if to suggest that businesses have no conscience.
Although it’s about chocolate sauce, many people are worried about all kinds of chocolate at the same time. If you had just received chocolate yesterday, what would you think if you saw it here?
Chocolate in short supply
In fact, only the price of palm oil, too one-sided.
Chocolate products contain a lot of oil. Chocolate is made from cocoa beans fermented and roasted, and natural cocoa butter is found in traditional chocolate.
But demand for chocolate has risen worldwide in recent years, and global cocoa production is expected to grow by nearly 25 per cent by 2020 to meet market demand.
In contrast, 1 / 3 of the cocoa trees destroyed by disease each year, coupled with recent droughts and global warming, have had a lot of impact on the cocoa harvest, and the shortage of cocoa beans is likely to worsen.
Chocolate demand is large, cocoa beans supply is insufficient, the use of other oils instead of cocoa butter, is the inevitable move of the development of the chocolate industry.
Chocolate has a unique smooth and delicate taste, the need to use a higher melting point of oil, the general vegetable oil can not meet the requirements.
Palm oil contains about 50% saturated fat and nearly 40% monounsaturated fat, which makes it a good substitute for cocoa butter because of its high melting point and good stability.
Chocolate companies have also used hydrogenated vegetable oils, but hydrogenated vegetable oils contain trans fats.
After the dangers of trans fats are well known, companies are looking for alternatives, and palm oil is a good choice.
It’s better than no chocolate, right?
Does palm oil really contain carcinogens?
Palm oil is vegetable oil from palm trees. Crude palm oil contains a lot of impurities, flavor, taste and processability are greatly affected, so it needs to be refined before use.
The refining process is usually treated at a high temperature of 200 °C, during which some by-products are produced.
Glycidyl fatty acid ester (GE) and chloropropanol ester are the two most concerned.
Let’s start with GE. If GE is hydrolyzed to form glycidyl, glycidyl is genotoxic and carcinogenic.
According to the European Food Safety Agency, it is not yet possible to find “intakes that do not increase health risks”.
In other words, as long as GE exists, it may pose a health risk, but it is difficult to judge how big the risk is. However, there have been no cases of poisoning due to GE.
Besides chloropropanol ester. At present, there is no limit of chloropropanol ester in vegetable oil in the world, after all, the establishment of standards requires the accumulation of sufficient scientific data.
Who has set the “safe dose” of chloropropanol esters, in particular 3-MCPD, at 2 micrograms per kilogram of body weight per day, compared with 0.8 micrograms per kilogram in the European Union.
In fact, not only palm oil, as long as the use of vegetable oil, food will be more or less brought into chloropropanol ester, but the amount is usually very low.
At present, scientists agree that these two things need to be paid attention to and paid attention to, but the research data is too little, and there are no cases of human poisoning caused by their use. It is still difficult to judge the extent of the harm.
On the whole, let the scientists be busy for a while.
Can you rest assured that you can eat chocolate?
Chocolate is divided into different purity of dark chocolate, milk chocolate, white chocolate and so on, sugar content has a lot of differences, but are high-fat and high-calorie.
So a good way to eat healthily is to pay more attention to the nutrition labels on the package when choosing and buying food.
You can clearly know the amount of heat, as well as whether palm oil or other vegetable oil has been added.
You know, the source of the most palm oil we eat is not chocolate, but a variety of fried processed foods.
To sum up, as a consumer, you should remember these points:
- Try to develop healthy and balanced eating habits and control the intake of each food.
- Palm oil is not “poison”, and foods containing palm oil are not “poisonous food”.
- Whether or not there is GE and chloropropanol ester, palm oil saturated fat content is high, should pay attention to eat less.
