Lake crab is high in nutritional value or river crab in high nutritional value

From the perspective of nutritional value, river crab and sea crab have their own advantages, and the nutrient content of different species is also slightly different.

River crabs have a slightly higher protein content than sea crabs.

River crabs have more than twice as much cholesterol as sea crabs.

The content of vitamin A, vitamin B1, vitamin B2 and vitamin E in river crabs is higher than that in sea crabs.

Sea crabs have higher levels of calcium, potassium, magnesium, selenium and other minerals than river crabs, and because they live in the ocean, they also have higher sodium content.

The nutritional value of river crab is relatively high, this kind of crab can achieve the effect of milking, can also reduce leucorrhoea can achieve the effect of leg length, can prevent low back pain, or limb numbness, can improve the body's immunity, can also supplement iron, calcium, can enhance physical fitness, meat is more fat.

The overall nutritional value of the two crabs has its own advantages:

The content of protein, vitamin A, vitamin E, iron, zinc and vitamin B group of river crabs is higher than that of sea crabs, so river crabs are more suitable for some friends who need to supplement protein, anemia, people who need vitamin A supplements for long-term eyes, and people who are prone to fatigue and have poor metabolism and need vitamin B.

The calorie and cholesterol content of sea crabs is lower than that of river crabs, and the content of minerals that are beneficial to blood pressure and bones is higher, so it is more suitable for people with high blood lipids, diabetes, high blood pressure, people who need calcium supplements, and friends who lose weight.

Personally, I think that sea crabs are more nutritious because the temperature in the sea is low, and the crabs grow slowly and are more nutritious.

The nutritional value of sea crabs is higher, because the environment for sea crabs to grow is better, and there are a lot of nutrients in the sea, and the number of crab roe will be more, which can make the body of sea crabs stronger, so the nutritional value will be higher.

Which is more nutritious, sea crab or river crab?

From the energy point of view, it can be seen that sea crabs are relatively low, and in terms of protein, river crabs are relatively high, and in general, crabs are indeed a high-protein food.

In terms of fresh weight, the protein content in 100 grams of crab meat is about 13 18. This value does not seem to be as high as the 20 of chicken and beef, but because the moisture content of crab meat is particularly high and the fat content is particularly low, if calculated by dry weight, its protein content accounts for 70 90 of the dry weight, which is difficult to achieve with other foods.

The nutritional value of sea crabs is higher, because this crab has a lot of protein, which can effectively replenish blood and vitamin B.

The nutritional value of sea crabs is higher, and sea crabs are rich in iodine, minerals, calcium and other nutrients.

I think they should have their own advantages, after all, the two live and grow in different environments, so the nutritional value is also different, and you can choose according to your preferences and tastes.

The protein content of river crab is relatively high, and its fat content is low, cholesterol is low, vitamin content is high, calcium, iron, zinc content are higher than the nutritional quality of sea crab.
