McDonald's fries were retested in the United States and found to contain high levels of harmful substances - trans fatty acids. According to reports, the US Food and Drug Administration believes that McDonald's fried food poses a threat to male reproductive function.
But McDonald's China has sent an urgent statement stating that McDonald's fries in China are fried in vegetable oil and do not contain trans fats. KFC has also clarified that the oil used by the company is not hydrogenated, so the content of trans fatty acids is extremely low.
It is reported that the United States has recently introduced a new method for testing McDonald's fries, and the results show that the content of trans fatty acids in each McDonald's fries has increased from 6 grams in the past to 8 grams, and the overall fatty acid content has increased from 25 grams in the past to 30 grams. The content of unhealthy trans fatty acids in each McDonald's fries has increased by one-third compared to before.
According to reports, the US Food and Drug Administration (FDA) has stated that trans fatty acids can increase the body's "bad cholesterol" and increase the risk of heart disease. At the same time, trans fatty acids can also reduce male hormone secretion, have a negative impact on sperm, and interrupt sperm response in the body.
McDonald's China stated that McDonald's tastes are the same globally, but the differentiation in different markets has led to slight differences in the composition of McDonald's products in each market.
For example, in Chinese Mainland, McDonald's fries use palm oil, and strictly comply with Chinese food safety, nutritional diet guidelines and laws and regulations to protect public health. Palm oil does not contain trans fatty acids.
In addition, KFC emphasized in an interview with reporters yesterday that the oil used by the company is different from McDonald's. They use oil that has not been hydrogenated, so the content of trans fatty acids is extremely low.
It is reported that there is currently no industry standard for the content of trans fatty acids in China, nor is there a method for detecting trans fatty acids.
