In the past, seafood mentioned by the ancients once included edible animals and plants produced in the sea, but when modern people mention seafood, they all refer to animal foods such as fish, shrimp, crab, shellfish and sea cucumber. In people's eyes, plant seafood such as kelp and laver seems to taste worse than seafood, and nutrition is not valued. In fact, in the eyes of health care workers, edible plants in the sea are rich in nutrition and have medicinal value, and their health care efficacy is far higher than that of seafood respected by modern people.

Rich nutritional value Most algae plants growing in the sea can be eaten, and there are many kinds, such as kelp, laver, laver, auricularia auricula and Gracilaria lemaneiformis. Previously, people didn't realize the value of these edible plants in the ocean. With the deepening of modern research, scientists have found that marine plants have incomparable nutritional value to vegetables and fruits on land.

Edible plants in the sea are rich in protein, dietary fiber, vitamins and minerals, and also contain a variety of bioactive components, such as seaweed polysaccharide, carotene, riboflavin, mannitol, peptides and so on. Edible plants in the sea are rich in vitamin B 12, which is equivalent to meat nutrition and is generally lacking in land plants. Edible plants in the sea also contain trace elements such as calcium, potassium, magnesium and iodine, which are much higher than those in land plants.

Algae polysaccharides in edible plants with various health functions can destroy the DNA of cancer cells, inhibit the proliferation of cancer cells, and have good anti-cancer and anticancer effects. The fat content of seaweed plants is very low, and the polysaccharides in them can effectively decompose cholesterol in blood and reduce the formation of thrombotic factors in blood. Therefore, eating these plants regularly can not only reduce weight, but also prevent cardiovascular and cerebrovascular diseases such as arteriosclerosis, hypertension and coronary heart disease.

Polypeptides contained in edible plants in the sea can activate islet cells and lower blood sugar, which is an ideal food for diabetic patients. Algae contains mannitol, which has good diuretic and antihypertensive effects, and also has a certain protective effect on renal function.

Edible plants in the sea are rich in dietary fiber and gum, which can absorb toxins and garbage in the intestine, promote gastrointestinal peristalsis, and quickly discharge toxins and garbage, and have outstanding effects in detoxification and beauty.

Edible plants in the sea are rich in nutrition and have remarkable health care effects, so they are called marine golden food. Due to the serious pollution in modern society, although these plants in the sea are all natural and green, they are inevitably not polluted by heavy metals in the sea. When choosing these foods, we should pay attention to their safety and try to choose good quality foods.
