Fish oil or cod liver oil, don't tell foolishly
Father's Day is approaching. Children who care about the health of the elderly particularly favor health care products. However, the reporter visited the market and found that the fish oil products often eaten by the elderly have a wide variety of functions and are often indistinguishable. I do not know how to buy them.
In particular, many people report that they are confused about fish oil and cod liver oil, resulting in confusion when taking it. The difference between cod liver oil and fish oil is only a single word, but it is actually a completely different and incorrect use. It will not only fail to achieve the desired effect, but also May damage health.
Cod liver oil long-term use or poisoning fish oil
Different compositions of fish oil and cod liver oil have different mechanisms of action on the human body. Chen Chaogang, director of clinical nutrition at Sun Yat Sen Memorial Hospital, Sun Yat-sen University, said that cod liver oil is a fatty oil extracted from the liver of marine fish. The main components are vitamin A and vitamin D. It can prevent night blindness caused by vitamin A deficiency, and at the same time it can help calcium absorption and promote the function of bone calcification. Fish oil is the collective name of all oil substances in fish, including body oil, liver oil and brain oil. The main functional ingredient of fish oil is rich in omega-3 polyunsaturated fatty acids (DHA and EPA), which helps regulate blood lipids and brain development.
Fish oil and cod liver oil should not be confused. Chen Chaogang said that if fish oil is taken as a dose of cod liver oil, fish oil cannot exert the effect of the drug because the dose does not reach the effective dose of fish oil; however, if fish oil is taken as the dose of fish oil, it will have a great impact. Both vitamin A and vitamin D are fat-soluble vitamins, and long-term high doses can cause harm to humans.
High levels of vitamin D can cause vitamin D intoxication, which can cause calcium deposits in the viscera. The data shows that the risk of kidney stones in postmenopausal women supplemented with 1000 mg of calcium and 400 IU of vitamin D can increase by 17%. Excessive amounts of vitamin A are also toxic. There are provisions that can tolerate the highest intake: infants and young children aged 0-3 years are 2000IU, 3000IU in 4-8 years old, 5667IU in 9-13 years old, 9333IU in 14-18 years old, and 10000IU in adults.
The exact function of fish oil is mainly to regulate blood lipids
"Hypolipemia, blood pressure, anti-thrombosis, anti-tumor, enhance disease resistance, brain stimulation, anti-aging." In the market, we can often see the various functions of fish oil propaganda. "Currently, the function is mainly blood lipid regulation," said Chen Chaogang. In 2014, experts from various professional committees such as the Chinese Society of Rehabilitation Medicine's Cardiovascular Disease Committee and the China Nutrition Society's Clinical Nutrition Committee jointly issued the "Cardiovascular Diseases Nutrition Prescription". The Expert Consensus stated that fish and fish oils (rich in EPA and DHA) are closely related to the reduction of cardiovascular disease.
The international "fish oil fever" began with the study of the diet of the residents in some areas. Chen Chaogang said that the most famous is the "Mediterranean diet," and Greece, Spain, southern Italy and other countries in southern Europe on the Mediterranean coast eat vegetables, fruits, fish, whole grains, beans, and olive oil, including fish. In the diet, deep-sea fish such as salmon, mackerel, and sardines can provide this important polyunsaturated fatty acid, which is associated with reduced risk of heart disease.
In addition, according to a survey report released by the Swedish Royal Academy of Sciences in the late 1970s, the Eskimos living near the Arctic Circle are dominated by seals and fish all year round. They rarely eat fresh vegetables but the Eskimos’ cardiovascular system. The incidence of the disease is lower than that of people in some countries. According to scientists, this is probably related to the Eskimos' preference for sea fish. Subsequently, Swedish and Dutch scholars confirmed through experiments that cold-water marine fish are rich in omega-3 fatty acids and have a significant preventive effect on cardiovascular disease.
Since then, "fish oil" has become a popular hot item in the international market. As in the Nordic countries such as Iceland, there is a natural Arctic Circle pollution-free deep-sea fishery resources. Deep-sea fish and fish oil have become regular visitors to the daily table, and the local life expectancy is also among the highest in the world.
Vitamin A easily oversupply, cod liver oil do not eat
Usually, in order to prevent rickets to ensure the child's healthy growth, vitamin D is required to be added from the first half of birth, and it has been said that calcium deficiency is actually a deficiency of vitamin D. According to Yuan Lijuan, chief physician of the Children's Hospital of Shanghai Children's Hospital, there are few natural foods containing vitamin D. Only the livers of oysters, clams, sardines and herrings contain a large amount of this fat-soluble vitamin.
Many children's specialist hospitals recommend a single vitamin D pill that can easily be adjusted to 400 or 800 units at any time, or 600 units per day alternately every other day. Past common cod liver oil, usually containing vitamin A1500 units and vitamin D500 units, if you need 800 units of vitamin D can not take 2 tablets, because vitamin A exceeds, vitamin A too much will hinder the effect of vitamin D, vitamin A also Easy to oversupply, because the food can provide the original vitamin A, the human body can convert it into active vitamin A, vitamin A originally from several carotenoids, fruits and vegetables with high vitamin A content of raw fruits and carrots, pumpkin, green peppers, spinach , cabbage and other green leafy vegetables, so adults can get enough vitamin A from food without additional supplements.
â– Tips
Use fish oil products to pay attention
Fish oil is good for health, but there are various kinds of fish oil products on the market. Chen Chaogang said that it is very important to choose high-quality fish oil products. When selecting products, it is recommended to focus on the following aspects:
1. Normal people do not need to specially supplement fish oil, and often eat some seafood and fish can fully meet the needs of the human body. Some people say that only deep-sea fish contain omega-3 fatty acids, but this is misleading. Shrimp, cuttlefish, squid, small yellow croaker, and octopus all contain omega-3 fatty acids, and some river fish also contain omega-3 fatty acids, but the content is lower.
2. People with dyslipidemia and family history of cardiovascular and cerebrovascular diseases may properly supplement fish oil. If they really need fish oil supplements, they should also be taken under the guidance of a physician or nutritionist.
3. Look at the quality control of fish oil products. Good fish oil products will strictly control environmental pollution factors such as PCBs, dioxins and heavy metals; large brands are generally more reliable; domestic products should be confirmed without overreaching public health foods. The CFDA website queries the lot number and allowed function declarations. Imported products are more reliable with GMP certification, such as the Risley Hi brand from Iceland.
Black glutinous maize is a special type of maize, whose kernel cuticle deposits melanin to varying degrees, giving it a dark and shiny appearance. The kernels are rich in water-soluble melanin and various essential trace elements, plant protein and various amino acids, with a significantly higher nutritional content than other cereal crops.
The origin of black glutinous maize: coloured glutinous maize is generally white, yellow, red, purple and black, with white, yellow and purple maize being the basic colours. The purple gene of a purple-white cross naturally becomes purple if it "beats" the white gene, and vice versa, so if the two make a tie, we see white and purple maize. Purple can turn into red and black maize, or as we often say, "red is purple and black is purple".
