Caviar is a nutritious food containing a large amount of protein, calcium, phosphorus, iron, vitamins and riboflavin. It is also rich in cholesterol and is a good supplement and growth agent for the human brain and bone marrow. . Caviar contains 63.85~85.29g of water per 100g; 0.63~4.19g of fat; 12.08~33.01g of crude protein; 1.24~2.06g of crude ash (crude ash also contains a large amount of phosphate and lime, with the average phosphate content reaching More than 46%, it is a good tonic for human brain and bone marrow). Eggs are also rich in vitamins A, B, and D. Vitamin A can prevent eye diseases, vitamin B can prevent athlete's foot and dysplasia, and vitamin D can prevent and treat rickets. In addition, fish eggs are also rich in protein and minerals such as calcium, phosphorus, and iron, as well as a large amount of nutrients such as cephalin. These nutrients are extremely important for the human body, especially for the growth and development of children, and they are easily lacking in our daily diet.

So, from a nutritional point of view, it is okay for children to eat some fish roe. However, we should pay attention to the elderly to eat as little as possible, because fish roe is rich in cholesterol, and it is not beneficial for the elderly to eat more. Children will not become stupid if they eat fish roe. Some elderly people say that children who eat fish roe will become illiterate and will become stupid. There is no scientific reason. At the same time, fish roe contains a variety of vitamins. Therefore, eating more fish seeds is not only beneficial to promoting development, strengthening physical fitness, strengthening the brain, etc., but it can also play a role in black hair and make people rejuvenated.

Although fish roe is very small, it is difficult to digest when eaten and difficult to cook thoroughly. After eating, it is easy to suffer from indigestion and diarrhea. Caviar, as long as we cook it thoroughly during the cooking process and do not eat too much when eating, will not only not affect intellectual development, but also help improve intellectual development and physical health. It should be noted that some fish roes, such as puffer fish roes, are poisonous and must not be eaten.

Q1. Eating fish makes you smarter?

Eating fish makes you smart because there are some omega-3 fatty acids in fish, which can synthesize brain functions when human brain cells are still developing. When the required fatty acid enzymes are insufficient, eating more can help the development of brain nerves (and retinol). In fact, adults are gradually developing conversion enzymes that can convert shorter chain omega-3 fatty acids into long-chain omega-3 fatty acids in human brain nerves. However, oils from terrestrial animals and plants, except for saturated fatty acids, are mostly omega-6 fatty acids. Only oils such as soybean salad oil have some shorter chain omega-3 fatty acids. For adults, the main benefits of eating more omega-3 fatty acids are to help control blood fat, lower blood pressure, slow down blood coagulation, and are good for cardiovascular prevention and treatment. Before children are four years old, it is mainly to supplement brain nerve materials, so adults and children should eat more seafood. However, it should be noted that not all fish contain a lot of omega-3 fatty acids. Deep-sea fish contain more fatty acids, and fish with more omega-3 fatty acids, such as swords, salmon, conger eels, turtles, and mackerel, are the best. Good source.

The nutrients absorbed by the mother during pregnancy not only affect the physical health of the fetus, but the latest research also points out that if women eat fish during pregnancy, the baby's language and communication skills will be better after birth.

Q2. Do babies whose mothers often eat fish during pregnancy have better language understanding?

This study is a research team from the University of North Carolina in the United States that analyzed the eating habits of 7,400 mothers during pregnancy. The results obtained. Researchers say that in the United States, pregnant women are advised not to eat more than 12 ounces of fish a week due to concerns about fish being contaminated by mercury in the ocean to prevent the mercury contained in fish from harming the fetus. In a minor UK study, researchers found that the benefits of eating fish during pregnancy outweighed the possible threat of contamination.

Daniel, a researcher at the University of North Carolina, pointed out that 70% of the women in the study ate fish at least once a week when they were pregnant. The biggest impact of these people's maintenance of fish-eating habits is on children's understanding of language. They tested the 15-month-old children of these women and found that children born to mothers who ate fish had an average score 7% higher than children born to mothers who did not eat fish; children who ate fish more often in the first year after birth were , and the results are relatively good. There are similar signs in social skills, but they are less obvious.

Daniel said, “Fish is a source of many nutrients that are good for women during pregnancy, but it is also a source of pollutants such as mercury.

He said that past research on the development of the fetal nervous system from eating fish focused on the possible harm caused by mercury pollution, while the potential benefits of eating fish were relatively undiscovered. Researchers tested the mercury levels in the umbilical cords of 1,200 newborns and found that they were generally quite low. Even if the mother's mercury content was high because she often ate fish, it had nothing to do with the baby's test performance.

Researchers say that eating 4 ounces of fish, one to three times a week, is enough to produce positive effects, and eating more does not increase the benefits.

Nurgent, a nutritionist from the British Nutrition Society, said that oily fish such as salmon and tuna are rich in omega-3 fatty acids, which are needed for the development of the baby’s brain and nervous system. Although this study does not Mentioned how often these mothers ate such fish during pregnancy, whether these babies were fed breast milk or cow's milk, and whether the diet after birth included fish, etc. However, research does show that pregnant women have benefits from eating fish during pregnancy. Follow-up More research is needed to understand the cognitive benefits of eating fish in young children.

The British Food Standards Agency recommends that pregnant women eat up to 2 servings of fish a week, while the average person can eat 4 servings.

Eat more fish and you will be healthier - fish is rich in DHA, a conductive substance needed by the cerebral cortex and retina

Q3. Is eating fish good for your eyes?

『 It is common knowledge that eating fish is good for your eyes, but how can fish protect your eyes and even promote eyeball development? There are clear studies in the medical community. Lu Dawen, director of the General Ophthalmology Department of the Tri-Service General Hospital, said that research has found that the unsaturated fatty acid DHA rich in fish is the main conductive substance in the cerebral cortex and retina, and the vitamin A rich in fish is the main nutrient for preventing night blindness.

The eyeball is found to be rich in unsaturated fatty acid DHA, especially in the retina. The human body is very mysterious. DHA does not appear in the retina for no reason, indicating that DHA is an essential fatty acid for the optic nerve and retina. Lu Dawen pointed out that the retina is like the integrated circuit of a large computer. It is the main "converter" for the objects that the eyes can see. Since the brain cannot directly judge light energy, all light energy that the eyes come into contact with must be converted into electrical energy through the retina. Only then can the brain receive signals and then see things.

Lu Dawen pointed out that although it is not clear what role DHA plays in the structure of the eyeball, a large amount of DHA is found in the retina, and this type of unsaturated fatty acid cannot be synthesized naturally by the human body and must rely on food. At this time, fish, which is rich in unsaturated fatty acid DHA, becomes the best choice for eye protection.

Lu Dawen said that another study found that prostaglandins, which cause inflammation in the body, are twenty-carbon unsaturated fatty acids, while DHA is a twenty-two-carbon unsaturated fatty acid. The elements are similar and may have antagonistic effects on each other. In other words, taking more DHA can inhibit the inflammatory response in the body.

In addition, the unsaturated acid DHA also has antioxidant capacity and can be used as a source of energy and a nerve conduction medium. The process of converting light energy into electrical energy requires a high amount of energy and many nutrients. In particular, DHA can replenish energy in a timely manner, so "eating fish to take care of your eyes" is based on research theory.

Q4. One of the foods that can change your life:

Wild salmon - provides essential fatty acids omega-3

Partner foods: black sea bass, oysters and Clams, sardines, flounder, canned mackerel, herring, trout.

Recommendation: Eat 2 to 4 times a week.

Not all fats are harmful to health. The unsaturated fatty acid omega-3 contained in salmon is one of the indispensable essential fatty acids for the body and helps

the body to produce ideal fats. cell membrane.

If the structure of the cell membrane is not perfect, the cells will not be able to obtain ideal nutrients, which will cause health to shine red

; these health problems include:

Stroke

Heart attack

Irregular heartbeat

Some cancers, such as breast and colon cancer

Diabetes

Asthma

Hypertension

Macular degeneration of the eyes

Chronic obstructive pulmonary disease (COPE)

Autoimmune system disorders, such as lupus erythematosus and rheumatoid arthritis

ADHD

Depression

Essential fatty acid deficiency is almost undetectable because its symptoms are not obvious. Symptoms such as dry skin, fatigue, easily broken nails and hair, constipation, frequent colds, inability to concentrate, depression and joint pain may all be caused by a lack of omega-3 fatty acids in the diet.

Q5. 1/3 of the salted fish eaten in the health market is unqualified and contains carcinogenic pigment saponin

Source: TVBS Reporter: Huang Zhiwei

Changhua County Health Bureau An inspection of the salted fish sold in traditional markets in September revealed that one-third of the salted fish sold illegally used industrial pigment saponin. Since saponin may cause liver cancer, the health bureau not only immediately ordered the operators to remove the unqualified salted fish from the shelves, but also today Take the initiative to distribute reagents to the market and allow people to DIY to check food safety. Canned tuna contains too much arsenic and damages the nervous system [2004-11-21]

Source: TVBS Reporter: Huang Chongtian and Leung Wai Hung Hong Kong report

People who like to eat sardines and canned tuna, please note According to the Hong Kong Consumer Council's test on imported canned sardines and tuna, it was found that cans from mainland China, Thailand, and Malaysia contain high levels of arsenic. Although they have not exceeded safety standards, arsenic will accumulate if consumed in large quantities for a long time. In the body, it damages the nervous and digestive systems. Industrial pigments added to yellow croaker in traditional markets hurt the liver [2004-11-21]

Preservatives are added to mainland food. The Taipei City Health Bureau announced a spot inspection report today. It was found that pickled yellow croakers, dried tofu and even... Industrial pigments are added to powdered balls to increase their color. Formaldehyde is added to pork, candied dates and vermicelli brought back from the mainland. The Health Bureau reminds that eating too much of these unscrupulous foods can seriously damage your liver and may even lead to death. Is seafood high in cholesterol? [2004-09-02]

Many people often think that seafood such as shrimps, crabs, and shellfish contain more cholesterol; patients with cardiovascular disease are often warned to stay away from such foods.

In fact, to judge the impact of food on cholesterol, we cannot just look at the amount of cholesterol in the food, but also consider the cholesterol and saturated fatty acids in the food. Now the nutrition industry has switched to the "cholesterol index" ” (CSI), replacing “cholesterol amount”.

The "cholesterol index" is an index that simultaneously calculates the amount of saturated fatty acids and cholesterol in food.

From the perspective of cholesterol-raising index, most seafood is lower than beef, pork, and chicken, said Zhou Xiujuan, a nutritionist at the Center for Chronic Disease Control and Prevention (please refer to "Cholesterol-raising Index of Common Foods" on page 115 surface").

And saturated fatty acids have a greater impact on cholesterol than the amount of cholesterol itself.

George Washington University cardiologist John. LaRosa said saturated fatty acids are four times more powerful in raising cholesterol than the cholesterol contained in food itself.

Because saturated fatty acids provide components for making cholesterol, they have the effect of raising cholesterol and are the killer behind heart disease.

Peng Qiaozhen, director of the Nutrition Department of National Cheng Kung University Hospital, further explained that even if shrimps, shrimps, and squids have high cholesterol levels, they are counted as whole. Cholesterol is only concentrated in the heads and yolks. As long as they are eaten, If the head and yolk are removed, it becomes a good food with low cholesterol and is very safe.

Moreover, eating more fish can protect your heart health.

Scientists were surprised to find in the 1970s that Eskimos have a very low rate of cardiovascular disease. The key may be that their main food source is marine fish rich in omega-3 fatty acids.

There are quite a few studies on omega-3, and almost everywhere in the world, people who eat more fish are less likely to have heart disease.

A Dutch study found that eating an average of one ounce of fish a day can reduce the chance of heart disease by 50%; a 25-year study in the United States found that people who don’t eat fish are less likely to develop heart disease than those who eat fish. People who eat fish are one-third more likely to die from heart disease; Danish research also shows that eating more fish is good for the heart.

The omega-3 fatty acids in fish fat can lower low-density lipoprotein (LDL, bad cholesterol), reduce platelet aggregation, lower blood pressure, lower triglycerides, etc., which can protect the heart.

However, it is worth noting that not all fish rich in fish oil are high in omega-3 fatty acids, said Chen Shumei, a nutritionist at Shin Kong Hospital.

Saury, mackerel, mackerel, and salmon are fish with high levels of omega-3 fatty acids; milkfish, cod, and mullet are high in fat but not omega-3 fatty acids. High; while tuna, yellow croaker, sea bass, and white hairtail fish contain almost no omega-3 fatty acids.

Since many studies have clearly pointed out the benefits of omega-3 fatty acids in fish oil, wouldn’t it be more convenient and direct to simply take fish oil capsules?

The overall impact of fish oil on arteriosclerosis is still inconclusive. For example, some studies in recent years have also found that fish oil may change the structure of LDL (bad cholesterol), making it easily oxidized, which is detrimental to arteriosclerosis.

At the nutrition expert meeting in 1996, the American Heart Association reviewed the relevant research on fish eating, fish oil supplementation, blood fat, and coronary heart disease in the past two decades, and put forward comprehensive suggestions: eat more Eat fish, but don't take extra fish oil. They believe that more research is needed to prove the benefits and dangers of fish oil in the future.
