Tea, whose production and consumption is quite common in our country, is the most consumed beverage in the world after water. In addition to its taste, the health-improving effects of tea have come to the fore again, especially with the studies conducted in recent years.
It is possible to say that tea is protective against many diseases, especially cardiovascular diseases and cancer types, as it is rich in flavonoids that have antioxidant properties.
Tea is mostly consumed as black and green tea. Black and green teas differ from each other due to the processes they are subjected to during production, and green tea, which has been less processed in terms of antioxidant properties, stands out one step further.
Studies have shown that those who consume more than 3 cups of black tea a day have a lower risk of heart attack than those who do not consume it at all. showed that it was 68% less than the It is also emphasized that tea types are protective against many types of cancer such as lung, colon and stomach, and it is reported that both green and black tea prevent the proliferation of cancer cells, and especially green tea is protective against stomach cancer due to its bactericidal effects. Since green tea consumption is very common, especially in the Japanese, the risk of lung cancer is low, even though cigarette consumption is high.
Caffeine is naturally found in tea, as in coffee, cocoa, cola and some medicines. There is approximately 40 mg of caffeine in 1 cup of black tea prepared using the classical method. Daily caffeine consumption should not exceed 300 mg. Since caffeine consumed in excess has a diuretic nature, it may negatively affect body fluid balance and cause negative consequences such as fatigue, irritability, insomnia and palpitations. Keeping the body fluid balance at appropriate levels is very important for maintaining health. Because 17% of deaths under the age of 5 observed in underdeveloped and developing countries are due to dehydration.
With obesity becoming a problem that threatens more and more people every day, attractive advertisements, especially on the internet, encourage people to become dehydrated. products, and people have developed a belief that what is natural is harmless. Especially the herbs contained in products sold under the name of slimming tea. Although r is known, the fact that their quantities are not included in the label information indicates that there is no standardization in this regard. The plants it contains are mostly muesli, diuretic and diaphoretic, disrupting the body fluid balance. Green tea is a plant that has come to the fore with its slimming effects, especially in recent years. What distinguishes green tea from other herbal teas is that it increases energy expenditure, in other words, accelerates metabolism.
One question that comes to mind when tea is mentioned is whether tea causes anemia. When plant and animal sources of iron are compared, it is known that tea negatively affects the absorption of especially plant iron sources. However, it would be wrong to attribute anemia only to tea and coffee consumption. Because iron absorption is affected by many factors.
To mention the precautions that can be taken to prevent tea from negatively affecting iron absorption; It can be said that not consuming tea, especially during meals, or even having a time difference of at least 1 hour between meals and tea, can eliminate the negative effects we have just mentioned. However, consuming animal-based foods rich in iron simultaneously with vitamin C is one of the factors that increase iron absorption.
In addition to a nutrition program that includes foods from the 4 basic food groups in balanced amounts, consuming 5-6 cups of tea a day is beneficial for health. It can be said that it will not create any negative effects and will even contribute to reducing the risk of chronic diseases and improving general health.
