"Not only clams, but all shellfish have almost the same nutrients." The clam is rich in nutrition, including protein, calcium, magnesium, iron, etc. The most noteworthy thing is that the clam is rich in trace element selenium, which is essential in human body. It can improve human immune function, prevent cancer, prevent cardiovascular and cerebrovascular diseases, protect liver, resist oxidation, delay aging, repair cells and protect eyes. At the same time, selenium can also remove wastes, garbage and toxins in the body in time, create a "green environment" in the body, and reduce the toxic and side effects of chemical carcinogens, pesticides and indirect carcinogens. Therefore, in order to eliminate toxins in the body, you can eat the clam with high selenium in moderation.

These three kinds of clams should have slightly different cooking methods at home according to their delicious taste and fat meat. Generally speaking, Astragalus seeds are fleshy and suitable for roasting and mixing. However, because of the thin meat, it is suggested that the methods of spicy frying and soup making at home are more delicious.

Pick the shuttlecock-remember "one look, two touches, three touches and four smells"

Choosing the clams to see if they are fresh is on the one hand, and the thinness of the clams is also very important. Experts teach you the four steps of selecting clams. Take a look, first look at the shell of the clam, whether the shell surface is shiny, if the color is positive and shiny, it means fresh, if the color is dark, don't buy it; Second touch, gently touch the open-mouthed shuttlecock. If you can quickly close your mouth, it means that the shuttlecock is fresh. If the shuttlecock "senses" slowly, it means that it is not very fresh. In addition, most of the clams are usually closed. If you look at a large number of clams with their mouths open in front of the clams booth, it may mean that they are not very fresh; Three times, grab a few clams and weigh them. If there is weight in your hand, it means that the clams are fleshy. If they are light, it means that the clams are thin and taste bad, so don't buy them. Fourth, smell the delicious taste of the clams. If it smells fishy, even if it is very light, it means that the clams are not too fresh, at least a large part of them are not fresh, so don't buy it.

Spitting sand, releasing salt water, nails, dirty water, changing in time.

There is a lot of silt in the clam. If it is not handled properly, it will be "biting" to eat. Experts suggest that the bought clams should be thoroughly washed with running water first, and then soaked in salt water. The ratio of salt to water is about1:100, and the soaking time is not limited. When the water becomes dirty, it is necessary to change another pot of water until the water becomes clear. It is also effective to put nails or iron products in the water.

The clam is cold, so it is not suitable for people with weak spleen and stomach (easy to have abdominal distension and diarrhea, fear of cold and fatigue). People also try not to eat when they have a cold and fever. Because shellfish mostly feed on seaweed, which is toxic, although the clam itself will not be poisoned, people are prone to allergic poisoning after eating the clam, especially if they eat more, so don't eat too much clam at a time, not more than half a catty (with the weight of the shell) at a time, and not more than twice a week at most. When cooking, it is necessary to match warm food such as onion and ginger to neutralize the coldness of the clams, and cooking should be sufficient. It should be noted that children's spleen and stomach are weak, especially children under five years old, it is best not to eat clams. Children over five years old can eat a few at a time, and never eat too much.
