Rio - In the story of Alice in Wonderland, the Mad Hatter character is destined to drink tea for life because time has punished him in revenge, stopping time at 6 o'clock - tea time. Outside of fiction, drinking too much tea would be great. Further studies, including one done in Brazil, proving that drinking tea and coffee every day increases longevity. This is because these foods are rich in substances that scavenge arteries, reducing blood pressure and prevent premature death of cells, including the brain. Coffee, for example, has an acid that reduces glucose absorption, preventing diabetes.

The latest research on teas, made with 83 thousand Japanese 45-74 years, followed for 13 years, says that drinking green tea reduces the risk of stroke by 14% to 20%. It seems little, but it makes a difference. This disease affects 16 million people worldwide each year. "If you do not have healthy habits, at least drink tea every day," said Yoshihiro Kokubo, lead author of the study.
Both green tea and black have a pigment that prevents clot formation in blood vessels, explains nutritionist Joice Amaro, Master of Public Health. "Hence its effect against stroke." The nutritionist Maia Simone, Cia Athletica, reinforces this view: "The power of tea is in substances called catechins. They act against premature aging and are anti-inflammatory. "
DRINK AT THE RIGHT TIME
So how did the Mad Hatter, one should take the tea at the right time. "Teas contain tannins, which may inhibit the absorption of nutrients such as calcium. It is better to drink tea outside of mealtimes at least an hour and a half later, "Simone teaches. "It is not good for tea and coffee after lunch, because caffeine competes with vitamin C and iron, may cancel these nutrients," says Joyce.
Drink in the right dose is healthier
The research indicating that drinking tea and coffee daily is good for health are conducted with specific groups of individuals in controlled doses and for specific periods. In general, drink up to 500 ml of green tea or white per day (about 4 cups) is enough to have the beneficial effects of the drink, says nutritionist Maia Simone.
As to coffee doses of 200 to 300 mg per day (3 cups) are considered safe and advisable to have therapeutic effects. "Teas and coffees are stimulants and should be avoided close to bedtime," says Simone.
Brazilian study demonstrates the unprecedented power of tea
Among a cup of tea and one of coffee, the Brazilian tends to prefer the latter. But the tea should make more space in the daily diet, when they think of health benefits. A Brazilian study, unpublished, which appears in the first week of April at the Congress of Cardiology Society of the State of Rio de Janeiro (SOCERJ), showed that green tea lowers blood pressure.
The research was done with women 25 to 59 years, at risk for hypertension (above 120 by 80) and obese, the Hospital Pedro Ernesto UERJ.
For three months they took every day, 500mg capsules of green tea extract. Result: the pressure fell. "Green tea contains substances that retard the aging of cells, strengthen the veins and arteries, reduce levels of bad cholesterol and protect against heart disease," says Livia nutritionist Paula Nogueira, coauthor of the study with Antonio Sanjuliani. "We capsules extracts, but it is likely that the consumption of the drink has the same beneficial effect."
The different kinds of teas
GREEN - This is what has been studied, and the research proved its effects. It's good to clear the arteries and has anti-inflammatory action. Helps reduce bad cholesterol, LDL, and increases energy expenditure.
It is obtained from the harvest of young shoots. It tastes sweeter and more delicate than green. And has high content of substances that prevent early deterioration of the arteries.
BLACK - It tastes less strong than the green. But it is also rich in substances that help maintain normal blood pressure, and others that accelerate fat burning.
RED - Its flavor is milder than the black and green. There are few studies on this it, but nutritionists say is good for lowering cholesterol and has anti-inflammatory action.
Cups therapeutic
BLACK - Less fatigue and improved attention and memory are the known effects of coffee. But that does more for health food. Coffee contains chlorogenic acid protects against diabetes, cardiovascular and other diseases caused by premature aging of cells, say scientists. Coffee also seems to prevent neurological diseases such as dementia. A likely explanation is that coffee ingredients prevent the accumulation of a protein between neurons, a cause of Alzheimer's. And there is another compelling reason to drink coffee: "It has antibacterial action," says Maia Simone. Another good news is that consumption of up to 3 cups per day does not increase the pressure.
