Can coronary heart disease patients drink tea?
Coronary atherosclerotic heart disease is a heart disease caused by atherosclerotic lesions in the coronary vessels that cause vascular stenosis or blockage, resulting in myocardial ischemia, hypoxia or necrosis. It is often referred to as "coronary heart disease". In recent years, due to changes in people's diet and lifestyle, the incidence of coronary heart disease has been rising, and it has become one of the cardiovascular diseases that seriously threaten health. But at the same time, studies have found that tea has a certain preventive effect on coronary heart disease!
For patients with coronary heart disease, diet is even more important, and many foods are not recommended. But usually people will have a misleading, that is, patients with coronary heart disease can not drink tea, in fact, drinking tea is not a taboo. Drinking tea in moderation is beneficial to coronary heart disease. It can reduce blood viscosity and blood lipids, thereby reducing the risk of coronary heart disease and stroke, and delaying aging.
Studies have shown that tea contains a variety of substances such as protein, amino acids, and tea polyphenols, which are beneficial to all aspects of the human body. Theophylline and a small amount of caffeine in tea can stimulate the spirit, promote blood circulation, reduce fatigue and diuresis, and also reduce the adverse effects of atherosclerosis on the kidneys. People with coronary heart disease are advised to drink more green tea, as green tea contains natural antioxidant flavonoids. Studies have shown that flavonoids can reduce cardiovascular disease morbidity and mortality.
The study found that tea drinkers suffered from coronary heart disease and stroke later and lived longer than their peers who never or rarely drank tea. Regular tea drinkers had a 20% lower risk of coronary heart disease, a 22% lower risk of death from coronary heart disease, and a 15% lower risk of all-cause death. This protective effect is most pronounced for people who have consistently maintained their tea drinking habit. This is because the active compounds (polyphenols) in tea cannot be stored in the human body for a long time, and only long-term tea consumption is effective.
The study also found that persistent tea drinking had a more significant protective effect on men. This may be related to the fact that there are many men who drink tea, and the incidence and mortality of coronary heart disease in women are lower than those in men, so the benefits of drinking tea are not obvious. Analysis of tea types showed that drinking green tea was effective in reducing the risk of coronary heart disease and extending lifespan, while black tea had no apparent protective effect in this regard. Studies suggest that green tea is rich in polyphenols, which may protect against cardiovascular disease and its risk factors, including high blood pressure and dyslipidemia. In contrast, in fully fermented black tea, polyphenols are oxidized to pigments and lose their related functions.
Although drinking green tea has a certain effect on the prevention and treatment of coronary heart disease, there are also the following points that need to be paid attention to:
- Avoid high concentration
Because tea contains a certain amount of oxalic acid, drinking a lot of strong tea will increase the content of oxalic acid in the urine, and it is easy to form oxalate crystals, which will lead to the formation of urinary stones.
In addition, drinking too strong tea damages the kidneys, stomach and blood vessels, which is equivalent to chronic suicide. Adults drink about 12g of tea every day, 3g each time, and it is suitable to brew with 150ml of water. If the amount exceeds this amount, it is strong tea.
- Avoid drinking tea before bed
Because tea contains caffeine, it has a certain stimulant effect. Drinking tea before going to bed may lead to insomnia. For patients with coronary heart disease, it will cause increased blood pressure and lipid metabolism disorders, which will affect the prevention and treatment of coronary heart disease.
- Avoid drinking tea on an empty stomach
Drinking strong tea on an empty stomach will not only cause gastrointestinal discomfort, loss of appetite, but also may damage the normal function of the nervous system. Drinking tea on an empty stomach also neutralizes stomach acid and inhibits gastric acid secretion, which may lead to indigestion.
In fact, drinking tea itself is a healthy eating behavior, but when it comes to patients with coronary heart disease, you really need to be careful, pay attention, and try to make the best use of tea. Don't drink tea because it affects your health is the most important thing.
