1. Are health products really useful?
Doubt 1: Does Cordyceps sinensis have a unique effect?
Cordyceps sinensis is a complex formed by fungi of ergotaceae parasitizing on the substrate of HYMENOPTERA larvae and their corpses. Cordyceps sinensis can enhance immunity and tonify kidney, which is relatively recognized and has clinical curative effect.
At first, people thought that cordycepic acid was the "most precious" component in Cordyceps sinensis, and many industries wanted to extract it. However, with the progress of science and technology, people gradually found that this rare ingredient is actually just a kind of mannitol, a very common industrial ingredient, and it is the raw material of Kaiser Dew, which costs only a few dollars in the market.
In 20 16, the state administration of pharmaceutical products also issued an approval, clearly pointing out that "Cordyceps sinensis belongs to Chinese herbal medicines, not to medicinal and edible substances", because its genuine Cordyceps sinensis contains heavy metal arsenic, which is fatal to human body. If you buy fake Cordyceps sinensis, it will contain more heavy metals such as lead and mercury, which will have a great impact on the human body.
Doubt 2: Is bird's nest really not as effective as eggs?
Bird's nest is so expensive, is it a universal tonic? Celebrity endorsement, e-commerce crazy sales In short, bird's nest nutrition has always given people a great impression.
Secret Jun: Don't believe it! Eating bird's nest is not as good as eating eggs.
Scientists carefully analyzed the composition of bird's nest. Studies show that dried bird's nest contains protein (50%), carbohydrates (30%), water and minerals (10%).
Carbohydrate can be understood as sugar, its main function is to provide energy for physical activities, and it is the cheapest nutrient for the human body to provide heat energy. Are there any other special places for most of the food?
The protein content of dried bird's nest is also high, but consumers of bird's nest health products will not take a big bite of bird's nest like tofu skin. Only wealthy families can eat a small amount of dried bird's nest every day, so they'd better eat protein in bird's nest directly (if an egg is 50g, it contains about 7g of protein). This is a fact.
But the quality of protein content is one-sided, and the quality of protein depends on its amino acid composition.
The protein amino acid composition of bird's nest is incomplete, and the quality of protein is far inferior to that of eggs. It can be concluded that bird's nest is just a very common food in terms of nutritional value.
Question 3: Where is the magic of enzyme?
With the appearance of enzymes, many weight-loss enthusiasts rushed to buy them, and even some merchants sold fermentation barrels to encourage people to make their own enzymes.
"Enzyme" is essentially another name for enzyme, which comes from Japan and was originally named "plant enzyme". After being selected by the merchants, it has become a bluff senior health care product.
Moreover, those health products and enzymes called "enzymes" on the market are not the same thing at all.
At present, the popular so-called enzyme products are mostly the products of sugar and fruit fermentation. Simply relying on it to supplement the body's need to lose weight will cause malnutrition.
Xie Mijun: Many people have the wrong idea that spending money on health is health care. In fact, health care does not need to spend money at all. It is better to eat food supplements, which are better than sleep supplements.
The simplest and most effective way to carry out this concept of health preservation is to sleep. People who sleep well will live longer.
This is not a rumor. In Li Yu's Collected Works of Li Weng in the Qing Dynasty, it was mentioned that "the key to health preservation is foresight. Sleep can restore essence, nourish qi, strengthen spleen and stomach, and strengthen bones and muscles. " It means calling on the human body to ensure adequate sleep, and adequate sleep time is the primary condition for high work efficiency.
There is some truth in this statement. Back to modern times, the latest medical research shows that the energy needed for one day's activities can be accumulated again for consumption after sleep, that is, to reserve new energy for the next day's activities. In a word, whether a person has spirit in a day depends on how much electricity he "charges" during his sleep.
So are people who sleep for 12 hours more energetic than those who sleep for 7 hours? Absolutely not, the key depends on the quality of people's sleep (whether they are interrupted during sleep, whether they enter an effective sleep period, etc.). ).
Xie Mijun's suggestion: stop working at 9: 00 ~ 1 1 every night, relax and rest, and then go to bed at 1 1.
"Yin Qi is all asleep (asleep) and Yang Qi is all asleep (awake)." Chinese medicine believes that when the sun is the weakest and the yin is the most abundant, sleeping at this time can nourish yin and the quality of sleep is the best. As soon as the sun supplements, people will naturally wake up and their spirits will wake up. Yang Qi can resist all diseases, and with proper exercise, maybe it really doesn't need the support of health care products.
2. How to maintain health correctly?
1. Sit down and pinch your knees.
As the saying goes, "when people get old, their legs get old first", while "when their legs get old, their knees get old first". The knee is the most complicated structure and the most vulnerable part of the human body. In addition, the knees are mostly ligament tissues and bones, and there are few muscles, that is, "more tendons and less meat", so the blood circulation here is relatively poor, and it always feels cool to touch the knees. Therefore, one of the key points of maintaining the knee joint is to heat and massage it. It is suggested that middle-aged and elderly people should form the habit of covering their knees with their hands when sitting on chairs and sofas, and give appropriate massage.
The specific approach is:
Put your hands and palms on the patella of your left and right knees respectively, and use the warmth of your palms to warm your knees. The naturally open five fingers play a massage role, which is equivalent to acupuncture. When massaging, first press radially outward around the patella with five fingers for about eight or nine times. Then put your fingers together and gently rub your knees, and finally rub your knees. Warm and kneading massage can promote blood circulation of knee joint together, thus nourishing joint and relieving joint pain and other symptoms.
Walking with clenched fists
Since ancient times, grip strength is a barometer of health. The greater the grip strength, the healthier it is and the longer its life span. Modern research also shows that the more flexible your fingers are, the less likely your brain is to rust. The research report on grip strength of University of London in recent 50 years shows that grip strength is an effective feature of longevity, and clenching fist is the easiest way to improve grip strength.
The specific approach is:
Tilt your wrist, fingers forward, palms down, then turn your wrist from front to back and make a fist. There are two main points in making a fist: one is to rotate the wrist, and the other is to press Laogong point with the middle finger. This is because the wrist has many original points of meridians, such as Taiyin Lung Meridian. By turning your wrist, you can stimulate all the original acupoints and strengthen the functions of related viscera. Secondly, when making a fist, the middle finger just falls on the Laogong point in the palm of your hand. Traditional Chinese medicine believes that Laogong point belongs to pericardium meridian. Pressing Laogong point has the functions of clearing away heart fire and calming heart fire. Usually, you can practice making fists while walking, pay attention to your wrists first, and then press Laogong point for 3 ~ 4 seconds to repeat the action.
Step 3 practice lifting anus while lying down
Lifting anus is a traditional way of keeping in good health. Chinese medicine believes that there are three meridians near the anus: Ren, Du and Chong. Ren pulse is always full of yin, Du pulse is full of yang, and Chong pulse is a sea of blood, which respectively governs yin essence, Yang Qi and sexual function of human body. The movement of lifting anus can promote the circulation of yin and yang. Among them, Yin Hui point is a very important point for longevity. Regular practice of lifting anus can play a good massage role on Yin Hui point and maintain reproductive function.
The specific approach is:
Shrink the anus slightly inward when lifting the anus, which is similar to the feeling of enduring defecation. Relax after 3 to 4 seconds, then lift the anus and do it repeatedly for a few minutes. Long-term persistence is helpful to reduce the occurrence of hemorrhoids and improve the symptoms of female urinary incontinence.
Stand up and lift your heels.
The foot is known as the "essence root", and the corresponding reflex zone of human reproductive system in the foot is the heel, so heel lifting exercise is beneficial to reproductive health care.
The specific approach is:
When practicing, you should completely raise your heel, and then slowly drop it to half the distance and quickly put it down, that is, bump your foot and shake your heel. This can strengthen the feeling of feet and exercise people's balance ability. Regular exercise for middle-aged and elderly people can prevent them from falling. The vibration caused by foot bumps also plays a benign massage role on the heel fat pad, which can relieve heel pain.
3. Daily health care knowledge
1. Slow health care in the morning: get up slowly and urinate slowly.
As the saying goes, "A day's plan lies in the morning", but the morning is also the most dangerous time. Although the bones and muscles have been stretched and the mind has become more sober, the organs and blood vessels in the body are still between dreams and waking. Therefore, the secret of keeping in good health in the morning is to be slow.
It takes three minutes to get up slowly. In the supine state, keep your eyes open and adapt to the alternating process from sleep to wake up. At this time, you can rub your hands and "dry your face" 1 minute. Then, sit up slowly in a semi-recumbent position and comb your hair with your fingers 100 times for 2-3 minutes. Then move your feet to the bed and sit still for 2-3 minutes. In the meantime, slowly practice deep breathing.
Secondly, urinate slowly. When you wake up in the morning, you may feel urgency, but the more urgent you are, the more you have to hold your breath. Because bladder emptying is easy to cause dizziness and even urination syncope. Urine as slowly as possible, not too fast and too hard, and hold the bracket when standing upright or squatting.
It is also important to drink water slowly. After a night of metabolism and water evaporation, you will get thirsty in the morning. At this time, if you drink a lot of water, it is easy to bring too much burden to your heart. The correct way is to pour a cup of warm water, first take a sip to moisten your mouth, then swallow it slowly, and then drink it in small sips, drinking 250-300 ml.
2. Exercise in the morning: Exercise more and do Sudoku.
From 9 am to noon 1, it is the most energetic and energetic time of the day. At this prime time, you should exercise at least 1 hour and use your brain for a quarter of an hour.
It is beneficial for the elderly to exercise at 9- 1 1 and 3-5 pm (when the weather is particularly hot, it should be chosen before 9 am and after 5 pm). 1 hour exercise, you can use 15 minutes to warm up, 30 minutes to exercise, and finally 15 minutes to stretch. After exercise, you can massage your waist and legs, sit down and lift your legs 10 minutes to relax and eliminate edema. People who don't exercise all the time can seize the scattered time to exercise. The so-called brain refers to positive thinking. No matter retired people or office workers, they can spare a quarter of an hour to do a few brain teasers or Sudoku during the break to really mobilize the potential of their brains.
When it comes to health care products, almost everyone believes it. If you are sick, you can cure the disease. If you are not sick, you can even prevent and beat cancer. But in fact, those so-called expensive health care products are not as magical as you think. Sometimes, doing more exercise, keeping fit and eating less junk food will be ten thousand times stronger than eating health care products.
