Consumer: Can crabs still eat?
The US media report quoted the staff of the New York Health Department as saying that the dangerous chemicals contained in New York waters are mainly PCBs, dioxins and cadmium, which will accumulate in the human body and may cause birth defects and cancer, which may cause heated discussion.
Recently, the domestic media investigated a number of aquatic products markets, breeding sites, etc., and interviewed the aquatic experts of the Municipal Academy of Agriculture and Forestry. The results confirmed that most of the crabs are currently farmed, and the water quality and ecological environment are safe and controllable. The rumored New York crab problem is limited to the local polluted waters.
Experts say that most of the domestic crabs are farmed and can be safely eaten.
Academy of Agricultural Sciences experts:
Crab safety is related to water quality
Experts from the Chinese Academy of Agricultural Sciences pointed out that the online statement is based on the prejudice. "Whether the crab is over-standard, whether it is harmful to the human body, at least from three aspects."
The first is that growing waters can affect crabs. If grown in good waters, the crab's heavy metal content is minimal. However, if grown in polluted waters, crabs will naturally be contaminated. Crabs that have problems in rumors should only refer to a polluted water in New York.
At present, most crabs in China are artificially cultured. Compared with the wild environment, artificial breeding has controllability. If the water quality, medication and other aspects are tested, the crabs raised can be safely consumed.
Secondly, from the biological point of view, the most vulnerable part of crabs is not crab yellow, but the crab, crab lung, crab liver and other inedible parts.
Finally, look at the intake. Eating crabs is seasonal, and crabs don't necessarily eat food. "The amount of food is generally small, and generally there is no problem."
Nutrition expert:
Do not eat more than 2 crabs at a time
Crabs are delicious, but they should not be eaten. Nutrition experts say that from the nutritional value point of view, hairy crabs are rich in protein, several times higher than the average fish, but also rich in trace elements. "Chinese medicine believes that hairy crabs are salty and cold, with heat and nourishing yin, promoting blood circulation and removing blood stasis. efficacy."
Experts suggest that people who eat crabs should keep their consumption within 2 or less. Crabs have high cholesterol and high protein, which will increase the burden of digestion. Especially in the elderly with coronary heart disease, high blood pressure and other diseases, younger children and patients with diabetes and kidney disease are not suitable for consumption. When eating crabs, do not eat beer, tea, persimmons, etc., which may cause digestive problems in the stomach.
In addition, while eating crabs, you can mix some vegetables and fruits to help metabolize and degrade some harmful substances.
