There are no side effects of eating tomatoes and shrimp together.

1, because shrimp is a class of allergens, it is true that some people can not eat. But this allergy has nothing to do with tomatoes and other ingredients, shrimp and crab in the body of arsenic mostly in the form of organic arsenic, is non-toxic, the highest limit of the relevant national standards is 0.5mg/kg fresh weight. The human body is not a suitable reactor, vitamin C to pentavalent inorganic arsenic reduction into trivalent arsenic is only a theoretical possibility, and has not been observed.
2, even if you eat inorganic arsenic close to exceeding the standard shrimp and crab, and all were converted into arsenic, as the legend says, "poisonous", even according to the lower limit of poisoning to calculate, also need to eat a few kilograms to be poisoned. The so-called "with taboos", in fact, is not based. So tomatoes and shrimp eat together is actually no side effects.
