1. Offshore carbon dioxide sequestration will affect the ecological environment
Gossip:
In recent years, offshore carbon dioxide storage technology has gradually emerged, but storing carbon dioxide on the bottom of the sea will pollute the marine ecological environment.
The truth:
Marine geological carbon sequestration refers to the transportation of CO2 to a site in the ocean through ships or pipelines and poured into geological bodies below the seabed for storage. In fact, the way of ocean storage is safer than storing carbon dioxide underground - this is because the coverage of seawater can not only avoid direct discharge into the atmosphere when carbon dioxide leaks, but also the additional seawater pressure reduces the requirements for the closure of the cover, so that carbon dioxide storage on the seabed has higher stability. Due to long-term seawater exchange, the pore fluid in the seafloor formation is closer to the chemical composition of normal seawater, which can avoid fracture activity induced by pressure imbalance during carbon dioxide injection to prevent the risk of leakage.
There is no direct evidence that marine storage pollutes the ecological environment. For example, the Sleiplier project in Norwegian waters began seabed storage in 1996, the first five years of engineering demonstrations proved to be safe, and since then it has been commercially operated, and has been perfusion for 27 years, and is still perfusion with no anomalies. Japan infused 300,000 tonnes of carbon dioxide in waters off Hokkaido in 2016-2019, which has been monitored so far and no safety risks have been identified.
2. Eating more spicy can prevent and treat diabetes
Gossip:
The ingredients in chili peppers can prevent and treat diabetes, usually eat more spicy, it is not easy to get diabetes.
The truth:
Studies have found that capsaicin in chili peppers is related to reducing fasting blood sugar levels and insulin levels, and eating spicy foods will promote fat oxidation and energy consumption, which may reduce the risk of diabetes, obesity and other diseases to a certain extent; Cayenne pepper may also increase the number of insulin receptors, improve insulin clearance, and improve postprandial hyperinsulinemia, and people who regularly eat spicy pepper will have a lower probability of postprandial insulinemia.
However, the claim that diabetes can be prevented and treated by relying solely on chili peppers is not rigorous. This is because diabetes is a chronic disease, and its cause involves a variety of factors, such as genetics, lifestyle, obesity, high blood pressure, high cholesterol and high blood lipids, etc., and the common "spicy food" in our lives, such as hot pot, spicy hot, etc. In addition to spicy, often have high oil, high salt and other problems, excessive eating may lead to the aggravation of other diseases.
In addition, diabetic people in the mainland are mainly middle-aged and elderly people, and whether the gastrointestinal condition can accept the stimulation of spicy food varies from person to person. If you usually eat spicy stomach discomfort, or have other uncomfortable feelings, it is not recommended to eat spicy; People with chronic cough and bronchitis dilation can not eat spicy, there will be a risk of inducing asthma, in the specific food choice should pay attention to adhere to the principle of light diet, moderate spicy food, pay attention to avoid heavy oil and salt cooking.
Diabetes prevention should begin with a well-rounded healthy lifestyle and treatment and management strictly as recommended by your doctor. We should develop good living habits, reasonable diet, moderate exercise, quit smoking and limit alcohol, and avoid excessive stress, so as to maintain good health and prevent the occurrence of diabetes.
3. Long-term wearing glasses will become "goldfish eyes"
Gossip:
Wearing glasses for a long time, the eyeball will gradually bulge and become "goldfish eyes".
The truth:
Bulging of the eyes is usually caused by the enlargement of the eye axis caused by myopia, which tends to occur in patients with high myopia. A pair of qualified glasses can help with vision correction. If you are myopic and do not wear glasses, unclear vision can easily lead to visual fatigue, and over time it will cause changes in visual functions such as adjustment and dispersion, which not only tends to deepen myopia, aggravate eyeball protrusion, and may even lead to strabismus.
Therefore, if you are myopic, you must go to a regular medical institution for standardized examination and scientifically dispense glasses.
4. If you have stomach problems, you should eat less and eat more meals
Gossip:
If you suffer from stomach problems such as stomach ulcers, you should change your eating habits and eat fewer meals.
The truth:
After the food enters the stomach, it will stimulate the gastric mucosa, causing it to secrete stomach acid, and the secretion of gastric acid will last for 2 to 3 hours after each meal. For people with gastric ulcers, "multiple meals" will constantly stimulate the gastric mucosa to secrete gastric acid, resulting in the ulcer of the stomach often eroded by gastric acid, which is not conducive to the healing of the ulcer surface.
The diet of patients with stomach diseases should pay attention to "regular quantitation, three meals a day, and thick and thin", so that the gastrointestinal tract will be healthier.
5. The slower the heartbeat, the better the body
Gossip:
The number of central beats in a person's life is a certain amount, the heartbeat is slow, the consumption is slow, and the life expectancy is long; The heart beats fast, the consumption is fast, and the life expectancy is short.
The truth:
Normal people's heart rate is 60~100 times / min when they are quiet, and athletes are slightly special, and the heart rate is generally about 50 times / min. Therefore, some people have the cognition that "the slower the heartbeat, the better the body". In fact, the reason why athletes have a slow heart rate is mainly due to long-term exercise, strong heart function, high efficiency, and fewer heart beats can meet the need to pump blood, so their heart rate is slow.
However, there is currently no relevant evidence to prove that the slower the heartbeat, the better, on the contrary, if the average person's heart rate is lower than 50 times / min for a long time, it is possible that because the blood pumped by the heart is insufficient, resulting in the body due to ischemia, lack of oxygen and episodic dizziness, palpitations, tiredness, fatigue and decreased exercise endurance and other symptoms, severe cases can appear angina, heart failure, syncope, and even sudden death.
Therefore, it does not mean that the slower the heart rate, the better. Within a normal heart rate range, maintaining a proper heart rate is more important for health and longevity.
6. The faster high blood pressure is lowered, the better
Gossip:
High blood pressure should be lowered quickly, and the faster the blood pressure is lowered, the better.
The truth:
This statement is a misunderstanding. Blood pressure is gradually increased, and blood pressure is gradually reduced. Blood pressure reduction can not be in a hurry, can not see that blood pressure is high, immediately take medicine to lower blood pressure.
If it is a hypertensive emergency, the blood pressure can be slowly reduced to 160/100 mm Hg within 24-48 hours, and if there are no special circumstances, it is not recommended to quickly and significantly reduce blood pressure, otherwise it will cause unexpected conditions such as cerebral hypoperfusion.
It is reasonable to lower blood pressure smoothly and drop blood pressure to the target level within 4 to 12 weeks. If high blood pressure is combined with life-threatening diseases, such as acute myocardial infarction, unstable angina, acute left heart failure, aortic dissection, etc., doctors will instruct the patient to reduce blood pressure to the desired level as soon as possible.
7. Ancient Chinese architecture does not use a nail
Gossip:
Chinese wooden buildings do not use a single nail, but rely on mortise and tenon structures.
The truth:
In the mortise and tenon structure, the wooden nails themselves are an integral part. When we visit many museums, we will see a semi-circular tube tile, often near the tile surface there will be a swastika eye, the complete set will have a ceramic nail or a decoration, that is where the tile nail is. Many tenons and tenons themselves also use nails, a wooden wedge nail, used for the overlap of two sections of wooden members connected with tenon and tenon joint, and use wedge nails to insert into the eye to ensure that the tenon and tenon members will not loosen due to sliding. This connection method will not loosen the structure due to the aging of the wood, unlike nails that force the wood itself to fix by squeezing, which is stronger and more durable.
In the maintenance and reinforcement of wood buildings, nails are also used extensively, especially iron nails. Due to its own organic matter properties, wood will have problems such as cracking, erosion, decay, and coming out over time, and traditional repair methods will use iron parts to reinforce.
It can be seen that nails are very common in Chinese wood structures, and most of the locations are in the building part above the beam frame, or in the mortise and tenon structure itself. The mortise and tenon joints or the part of repair and maintenance are often relatively hidden, paying attention to "repairing the old as the old", seamlessly integrated, and trying not to leave traces. Therefore, when visiting ancient buildings, if you do not observe specifically, the chance of seeing nails is actually not great.
Therefore, nails and wooden ancient buildings are actually complementary to each other, although wooden works can be built through mortise and tenon structures, but the use of nails is the guarantee of the firmness and durability of the tenon and tenon structure itself.
8. Bamboo charcoal food can detoxify and rejuvenate
Gossip:
Bamboo charcoal can absorb harmful substances in the human body, purify toxins in the blood, and also help the human body to digest and excrete, cleanse the intestines, and have the effect of detoxifying and rejuvenating.
The truth:
Bamboo charcoal food refers to adding a certain amount of edible bamboo charcoal powder to food to make food have "additional nutritional value". Bamboo charcoal itself has a strong adsorption effect, can be placed in the room or refrigerator as a moisture absorbent, deodorant, etc., but experts said that the adsorption performance of bamboo charcoal is not the same as the principle of adsorbing toxins in the human body, and the function of the so-called "adsorption of toxins in the body" is not credible and has no scientific reason.
For normal people, bamboo charcoal, activated carbon, etc. cannot be digested after swallowing as foreign substances, and eventually they are basically excreted as they are, which not only does not play a good role, but also affects the absorption of nutrients, causing problems such as indigestion and constipation.
In addition, in the mainland food additive use standards, bamboo charcoal is not allowed to be used as a food additive. Consult the "Hygienic Standards for the Use of Food Additives", vegetable carbon black can be used as a colorant in the production and processing of some foods, and plant activated carbon can be used as a processing aid in the food industry, but it should be removed before making the final product. Therefore, bamboo charcoal food is actually a food processed with materials not allowed by the state, and its functional effects and safety such as detoxification in the human body have not been scientifically and effectively verified, and consumers should be cautious.
9. "Fugui bag" is fat
Gossip:
The "rich bag" on the back of the neck is because it is fat, which does not affect health.
The truth:
The "rich bag" is a large bag that grows at the back of the neck. Some people have excessive lordosis in the lower part of the cervical spine, and excessive kyphosis in the upper part of the thoracic spine, which will lead to kyphosis and fat accumulation, forming a "rich bag". "Fugui bag" is mostly caused by long-term bowed head posture, such as long-term bowed head work, study, long-term playing mobile phones, computer games, pillows are too high, etc., and there is no clear correlation with fat and thin.
"Rich bag" is not only not rich, but also a health hazard. The larger its volume, the more severe the symptoms. It not only affects the physical beauty, but also makes the shoulder and neck back muscles often appear tense and stiff, sore and painful, and even radiates to the head and neck, back or shoulders, causing upper back swelling pain, numbness in the area around the mass and other symptoms. Generally speaking, the larger the size of the "Fugui bag", the more severe the symptoms.
In addition, "Fugui Bao" may also affect the blood supply to the brain, which is associated with cardiovascular and cerebrovascular diseases such as dyslipidemia and hypertension, and individual patients will have sympathetic nerve irritation symptoms such as tachycardia, arrhythmia, increased blood pressure, chest tightness, insomnia, etc.
In daily life, we should pay attention to prevention, correct bad living habits, and avoid chronic neck injuries. Be sure to sit in a straight posture and the computer screen should not be lower than the line of sight. It is necessary to adhere to the exercise of the neck and shoulder muscles to maintain the stability and grace of the cervical spine. Do not work or play with your head down for a long time, and do more movements of holding your head high and stretching your neck.
10. Drinking sparkling water can lower uric acid
Gossip:
Carbon dioxide sparkling water belongs to "alkaline water", often drink can lose weight, slimming, lower uric acid.
The truth:
After drinking sparkling water, the carbon dioxide contained in it enters the human body to produce bicarbonate ions - bicarbonate is a weak alkaline ion, which has a certain effect of neutralizing uric acid, which is also the main "basis" of "bubble water lowering uric acid" in the flow legend. However, in the face of a powerful human body system, the acid-base neutralization ability of sparkling water is really a "drop in the bucket", which can not cause acid-base changes in the human body, let alone achieve the therapeutic effect of lowering uric acid.
As for the statement that "sparkling water can produce satiety, thereby reducing calorie intake, achieving weight loss and reducing uric acid", its role in reality is also limited.
In fact, sparkling water has a fresher taste and a richer drinking experience, and you don't have to be obsessed with health effects, and you can drink it purely for the purpose of happiness.
