Coffee and tea the harm and benefit.
In recent times the trend — where there is a wide selection of tea, most people opt for coffee. Although green tea is gaining popularity among people who look after their health, consume it is not as common as coffee and coffee drinks.
Tea, Coffee, and Caffeine
Tea and coffee contain caffeine, but coffee usually contains 2-3 times more. Caffeine has some negative physiological effects. Negative effects of caffeine are increased anxiety, panic condition becomes harder to fall asleep, decreased digestion and headaches. Which in turn can act as a
catalyst and "the last straw" for cancers and large of heart problems. If You are concerned about the negative influence of caffeine, the remedy shall be to herbal tea or decaffeinated coffee.
Some studies have shown that people who ate coffee significantly increases the level of cholesterol in the blood, which increases the risk of coronary heart disease. As it turned out, the caffeine in coffee, is responsible for improving blood cholesterol. This happens due to the fact that coffee contains two natural chemicals called "diterpene compounds" — cafestol and caveolae, which affect a significant increase in LDL cholesterol (the so-called «bad cholesterol»).
Five cups of coffee a day can raise cholesterol levels by as much as 5-10%. If coffee is consumed with sugar and cream, this further increases the level of lipids in the blood. Scientists have proved that regular consumption of 5 or more cups of unfiltered coffee a day with cream and sugar, easily increases the risk of cardiovascular disease, and heart attack from 30 to 50%.
What about filtered coffee (household coffee makers)? Passing through the paper filter removes the majority of diterpene compounds, and thus filtered coffee has less influence on the increase in the level of LDL. However, recent studies have shown that consumption of coffee increases the level of homocysteine. Accumulate in the body, it attacks the inner walls of arteries, forming gaps that the body tries to heal. Then the damage is directed calcium and cholesterol, forming atherosclerotic plaque, which narrows and sometimes completely occludes the vessel lumen. This usually leads to a blood clot or rupture of the vessel, with all its consequences, such as stroke, myocardial infarction, lung embolism, and even death.
Later studies have shown that elevated homocysteine increases twice the risk of Alzheimer's disease.
The benefit of tea
There is growing scientific evidence that regular consumption of tea may reduce the risk of cardiovascular disease and even help to reduce your overall risk of developing cancer. Black and green tea contains many beneficial natural chemicals called flavonoids. In humans, flavonoids increase the activity of enzymes of metabolism. Some flavonoids have antimicrobial and antibacterial action. Flavonoids can reduce the oxidation of the particles of cholesterol and/or decrease the tendency of platelets (cells that play an important role in healing and repairing damaged tissues) to linger on the walls of the arteries. This suggests that black tea can reduce the risk of clogged arteries and/or heart attack. Scientists Wales have studied more than three thousand elderly patients and found that those who frequently drank tea, had less atherosclerotic lesions in the aorta. Recently, five research scientists Rotterdam showed that 70% lower risk of heart attack in people who drank 2-3 cups of black tea a day. The conclusion of the study — an increased intake of tea and flavonoids may contribute to the primary prevention of coronary heart disease.
