Zhao Shunrong, pharmacist, chairman of Taiwan Province Preventive Health Care Association, said that vitamin B plays the role of "coenzyme" in helping enzymes metabolize nutrients, and is responsible for digesting food and generating and supplying energy for physiological operation. It is an important metabolic tool for the body. Therefore, when the intake of group B is not enough to play the role of coenzyme, the human body will naturally feel weak.
The combination of group B and coffee will make people feel more tired.
It is worth noting that caffeine in coffee will not only accelerate the blood circulation of human body, but also accelerate the consumption of vitamin B group. Therefore, it is widely rumored on the Internet that the combination of "Group B+Coffee" not only doubles the refreshing effect, but also makes people feel more tired, which is worth noting!
Therefore, for friends who are used to drinking coffee, it is best to take Group B with an interval of 30 minutes to 1 hour, and choose long-term basic dosage and long-term release of "sustained release tablets" to provide what the human body needs.
Note that the half-life of caffeine is related to age and liver function.
Caffeine is a xanthine alkaloid compound, and its main source is the seeds of coffee trees. It mainly exists in the fruits and leaves of coffee tree, tea tree, Paraguay tea and Guana tea. It is a central nervous system stimulant, which can temporarily dispel drowsiness and restore the spirit.
Caffeine will be absorbed by the gastrointestinal tract within 45 minutes after ingestion. The half-life of caffeine, that is, the time it takes for the body to convert half of caffeine intake, will be related to age, liver function, whether drugs are used or not, and the number of enzymes related to caffeine metabolism in the liver.
The half-life of caffeine in healthy adults is about 3-4 hours, which is extended to 5- 10 hour in women who take oral contraceptives and 9- 1 1 hour in pregnant women. Smoking will shorten the half-life of caffeine. When there is liver disease, caffeine will accumulate and the half-life will be extended to 96 hours.
Caffeine is not excessive. Enjoy coffee without any burden.
Pharmacist Zhao Shunrong said that according to the evaluation data of the European Food Science Committee, the daily caffeine intake is below 300 mg, which should not cause adverse effects on health. According to the British Food Standards Agency's recommendations on caffeine intake, the daily intake of caffeine per person should not exceed 300 mg.
In fact, the calorie of coffee itself is very low, about below 20 calories, and it contains almost no fat. However, if creamer, cream balls and sugar are added, it will not only increase the burden of calories and oil, but also threaten the terrible killer of cardiovascular health. Therefore, it is recommended not to add cream and cream balls, or to replace low-fat milk or sugar, which should be healthier.
Drinking coffee doesn't want to hurt your stomach. Avoid drinking on an empty stomach.
I want to drink coffee, but I don't want to hurt my stomach. How to drink is better? Coffee causes stomach upset, mainly because caffeine causes a large amount of gastric acid secretion, which causes or relaxes the extensor muscles at the lower end of esophagus, thus causing gastroesophageal reflux.
Pharmacist Zhao reminded that it is best not to drink alcohol on an empty stomach, which is easy to cause gastric ulcer, and the diuretic effect of caffeine will increase the excretion of calcium, which indirectly leads to the decrease of bone mineral density. Therefore, people who drink coffee are advised to pay more attention to calcium supplementation, exercise and drink more water to avoid water loss. Usually eat more milk, dried fish, cheese, vegetables or calcium tablets.
In fact, caffeine exists not only in coffee, but also in drinks such as cola and black tea, but not so much. Therefore, when there are cardiovascular diseases, arrhythmia, osteoporosis, gastrointestinal diseases and pregnancy, it is best to avoid or reduce drinking caffeinated drinks. Pharmacist Zhao reminded that pregnant women should consume less than 300 mg of caffeine every day. It is best for women over 50 to reduce caffeine intake. If they really want to drink coffee, they should not drink more than 2 cups a day. People with digestive tract diseases, such as gastric ulcer and duodenal ulcer, should temporarily avoid drinking coffee.
These people can supplement group b in moderation.
As for group B, who needs to supplement it? People suffering from diseases such as angular stomatitis and neuroinflammation, or those who spend a lot of money on night shifts, staying up late, socializing and drinking, and those who have vegetarian habits and often drink, the elderly, pregnant women and renal dialysis patients, due to special physiological changes and lifestyle changes, and during the period of weight loss and slimming, due to the need for a lot of energy to enhance metabolism, additional vitamin B groups should be properly considered.
There are many kinds of foods containing B family in daily life. Various vegetables, fruits, milk, eggs, beans, fish, meat, nuts, etc. all contain different vitamin B components.
How to choose group b? Pharmacist Zhao suggested that health care products that have passed the quality and safety certification of inspection institutions certified by the Ministry of Health should be selected to achieve the benefits of preventive health care. Because the amount of group B ingested by the human body in one day is not fixed, there are already "sustained-release tablets" that provide long-term basic dose of group B and release it for a long time, which is more suitable for groups with large activity, long working hours and great mental stress. Although vitamin B is a water-soluble substance, excessive intake will be excreted with urine and will not accumulate in the human body. However, it still needs to be reminded that a single dose of excessive intake of group B may still bring certain health effects.
Pharmacist Zhao's health advice;
What suggestions do office workers have for refreshing themselves? In fact, as long as we maintain a normal work and rest, don't stay up late, implement a "balanced diet", fry less, barbecue less, eat more fruits and vegetables, drink more water, and develop moderate "regular exercise" on weekdays, we can build good physique and resistance, and also take the opportunity to adjust bad living habits and add points to our health.
According to the evaluation data of the European Food Science Committee, the daily intake of caffeine is below 300 mg, which should not cause adverse effects on health.
