What else can't be eaten besides the crab's lungs? What else can't be eaten besides the crab's gills?

Crab is a very popular nutritious food. It is rich in protein, minerals and other trace elements, etc. It has a good edible value and is deeply loved by people. Many people like to eat crabs, especially in autumn. There are certain rules for eating crabs. Some parts of the crab cannot be eaten. So what parts of the crab cannot be eaten? Let's take a closer look!

Which parts of crabs can't be eaten?

Crab intestines

First, let's take a look at the crab's abdomen. On the crab's belly, there is a crab navel that can be opened, and inside it is a black object, which is the crab intestine.

Crab intestines are very dirty and contain crab excrement, so they cannot be eaten. We can just tear off the entire crab navel and throw it away.

Crab stomach

Next, open the crab's back shell, and what comes into view is the full crab roe!

Don’t rush to eat it. There is a triangular capsule hidden in the crab’s back shell. This is the crab stomach. It is hidden in the crab roe. You have to find it carefully.

There is undigested food in the crab's stomach, so it tastes bitter. If it is not removed cleanly and eaten together with the crab roe, the crab roe will taste bitter and affect the taste.

Crab gills

On both sides of the crab body, there are some eyebrow-like objects, similar in texture to sponges, which are crab gills. The crab's gills are their respiratory organs and are also very dirty, so they cannot be eaten and must be plucked out completely.

Crab Heart

Finally, let's talk about the crab heart. This part is hard to find and many people tend to ignore it. Under the black film in the middle of the crab body, there is a small gray-white hexagonal object, which is the crab heart. Crabs themselves are very cold, and the crab heart is especially cold. If you eat it, it is easy to accumulate coldness in the body, which is not good for your health, so you should remove it.

How to Eat Crabs Healthy

Many people say that crabs have high cholesterol. In fact, only the head and roe have high cholesterol. If you only eat the meat, you don't have to worry too much as long as you don't eat too much. In addition, the polyunsaturated fatty acids in crab meat are beneficial to lowering bad cholesterol in blood vessels and are good for health. Just like cooking meat, it is best to steam or boil crabs, not fry them.

Although crabs are very good food, people with poor digestion, cholecystitis, gallstones, gout and other diseases should not eat them, while people with high blood pressure and high blood lipids should not eat crab roe. Of course, people who are allergic to seafood should also be careful. Because crabs are cold in nature, people with weak constitutions or weak bodies should eat less, or use seasonings such as onions, ginger and garlic to neutralize the coldness.

You should also avoid eating crab meat with tea or persimmons, because the tannic acid and other ingredients in them will coagulate the crab meat protein, which is not conducive to digestion, and in severe cases, people may even vomit or have diarrhea. In addition, crabs should not be eaten with beer, because beer will produce too much uric acid, which can easily cause gout.

How to choose crabs

The most important thing to look at when choosing crabs is the crab's vitality. You can shake the crab's eyes with your hand. If it can dodge quickly, it means it is still very alive. Then look at the weight. Some crabs look very big, but they are not as heavy as you imagined when you weigh them with your hands. It is best not to buy such crabs. Thirdly, check whether the crab's body is solid. You can pinch the first knuckle of the crab's leg closest to the body. Choose the ones that are full and meaty. Also pay attention to whether the joints are black. If so, it means it is not fresh. Finally, check whether the crab's body is damaged or bruised, which may affect the quality of the local meat.
