Autumn winds rise, crab feet itch. Crab as a fall aquatic delicacy, attracted foodies stupid. However, there are folk rumors that crabs can not be eaten together with tomatoes, otherwise it will form arsenic poisoning. This claim has triggered a wave of surprise and skepticism among netizens, who are inevitably more careful when eating crabs. Such rumors have been circulating in folklore for many years, the public are more convinced that this statement, or rather believe it, will be in the life of the two to avoid eating together. But some experts have looked through a large number of books and literature to understand "that crab thing", found that the crab is wrong, these are not the crab's fault.

Truth: Eating a very large amount of crabs and VC is likely to be toxic, and this possibility has not found enough evidence.

Nutrition and chemical experts said that, theoretically, the crab body contains pentavalent arsenic, is a compound, it is possible to be tomatoes in the VC reduction into trivalent arsenic, trivalent arsenic may form arsenic trioxide, which is often referred to as arsenic. But the human body environment can occur such a reaction, has not yet been confirmed from the official official scientific research results (including the U.S. FDA data).

Commercially available crabs require arsenic levels (by wet weight) of no more than 0.5mg/kg, and generally uncontaminated crabs are far from reaching this limit. And arsenic contamination can be accumulated through the food chain in many foods, that is to say, such as aquatic products, grains and even drinking water will contain a certain dose of arsenic, but in the safety threshold range will not cause harm to human health.

According to Nutrition and Food Hygiene, the daily allowable intake of arsenic is 0.05mg per kilogram of body weight, and for an adult man weighing 70kg, the daily allowable intake of arsenic is 3.5mg. Without taking into account the human body's ability to react to it or not, or the human body's digestibility, conversion rate, absorption rate, and under the premise of settling with 1mg as the maximum allowable intake, it is necessary to consume more than 20kg of crabs and more than 20kg of crabs at a time, as well as the maximum allowable intake. If we take 1mg as the maximum permissible intake, we need to consume more than 20 kilograms of crabs and more than 5 kilograms of tomatoes at one time in order to have a toxic reaction, while the lethal dose would require consuming several hundred kilograms of crabs at one time, which is not possible in reality.

Conclusion: rumor busting. This rumor is a masterpiece of scaremongering with a low-level knowledge of chemistry. Seafood inorganic arsenic content is very low, even if the vitamin C can be reduced to get arsenic, so a small amount, even the toxic reaction will not appear, not to mention the "violent death". The same: vitamin C and shrimp with food will be poisoned is the same reason.

Crab can not eat with what food

Crab + Sydney: cause diarrhea, gastrointestinal damage

Crab + pear: the two together, hurt the stomach

Crab + loach: the opposite of the function, should not be eaten

Crab + persimmons: together will be sick, poisoned

Crab + perilla: abdominal pain

Crab + perilla leaves: the first time in the past year, the first time in the past year, the second time in the past year, the first time in the past year, the first time in the past year, the third time in the past year, the first time in the past year. p>Crab + cherry tomato: produce arsenic will be poisoned
