Per one hundred grams of shrimp 991 mg of calcium, in the food is considered to be relatively high in calcium, but if you only focus on the amount of a nutrient contained in the food, it is a little too one-sided, because the shrimp, although the calcium content is relatively high, however, there are also several unfavorable to the existence of their own calcium factors, which ultimately lead to the shrimp, this food, and can not be Become a calcium star.

2/7

First of all, the consumption of shrimp is not high.

Shrimp skin, although appearing on the dinner table very often, but as a side dish, the amount of food consumed at each meal is not large, and the amount of food consumed by each person per day is even smaller. Calculated in accordance with the daily calcium needs of adults 800 milligrams, if half of the calcium content needs to be supplemented by shrimp, about more than 40 grams, this amount is far from being reached, do soup shrimp probably not more than 5 grams of use at a time.

3/7

While shrimp skin is high in calcium, it is also high in salt.

Each hundred grams of shrimp in the sodium content of more than 5,000 milligrams, this amount is far more than the Chinese residents dietary guidelines for adults daily salt recommendations, from this point of view, shrimp even more can not eat. And shrimp contains traces of nitrite, is not suitable for long-term consumption of large quantities, so it seems, by eating shrimp calcium, is simply a luxury.

4/7

Secondly, the calcium in shrimp skin is not well absorbed.

No matter how to cook, shrimp can not be completely chewed by the teeth fine, although into the stomach can still be digested under the action of gastric acid part, but most of the shrimp ingredients will still be discharged with the feces, in this way, we just rely on eating shrimp to estimate the amount of calcium to supplement the amount of calcium, it is a false high.

5/7

Many people also choose to bake dried shrimp with a cooking machine after crushing, stir-fried vegetables as a seasoning, so after processing, shrimp absorption rate will indeed increase, but in the way of the amount of limited, so the human body still can not meet the daily demand for calcium. But as a family life use, is a good way.

6/7

Finally, the calcium content is not the only thing that counts, but the factors that promote the absorption of calcium are also critical.

Vitamin D in food, lactose, the right amount of protein are effective factors to promote the absorption of calcium, but these conditions are not in the shrimp, just rely on purely high calcium content is not to solve the fundamental problem. In contrast, we have to talk about the real master of calcium, is milk. Simply look at the calcium content, milk is not high, but which promotes the absorption of calcium lactose, protein, vitamin D has played a good role in helping calcium absorption.

Thus, shrimp skin calcium, really not so reliable.
