TEEKANNE tea & health

Tea is a special drink that is as good for the body as it is for the spirit. The subtle aroma of over 150 active substances and the pleasant taste alone create a sense of calm and mobilise our inner energies.

But tea is more than a good-tasting drink.

Its positive effects on our health have been known for thousands of years. For some decades now, scientists have noted that tea drinkers are often healthier than people who don’t drink tea.

They suffer less frequently from certain kinds of cancer and glaucoma, cardiovascular diseases and cavities. Many scientific studies have attempted to discover why.

Substances in tea

Modern analysis methods are identifying more and more substances in tea. To date, more than 400 have been found. The most important are the polyphenols (previously called tannins), which make up about 30%, and caffeine, which makes up about 5%.

Others: essential oils, trace elements, minerals, enzymes, amino acids, vitamins, fluoride, and many more. While some of the substances in tea remain the same when the leaves are processed into white, yellow, oolong or black tea, some of the polyphenols are converted and other substances created. New catechin compounds are created, pigments develop, and the flavours change. The highest levels of catechins, especially the epigallocatechin gallate that has been identified by many authors as an important antioxidant, can be found in green and white teas because they have the lowest degrees of conversion into pigments and other active substances.

What makes tea so healthy?

It is the apparent interaction of the many active substances, which together with the polyphenols not only stimulate through caffeine but also protect against damage caused by everyday life, especially when consumed regularly.

What are antioxidants and how do they work?

Antioxidants capture the harmful “free radicals” in the body. Free radicals arise during metabolism in the organism, but are also formed when the body is exposed to harmful environmental influences, tobacco smoke and UV radiation. If they are not captured, they can cause damage to the body and DNA, and can also cause cancer. Antioxidants are beneficial for the body in different ways, for example by strengthening the immune system, preventing vascular disease and high blood pressure, protecting against skin damage and cavities, lowering the risk of cancer, and even slowing the ageing process in the cells.

For a healthy heart
Sadly, cardiovascular disease is the most common cause of death in western countries. Arteriosclerosis causes the arteries to narrow, and increases the risk of heart attacks. Scientific studies have proven that the antioxidants contained in tea at least reduce plaque deposits in the blood vessels, thereby helping to prevent cardiovascular conditions. This means that tea drinkers have a considerably lower risk of arteriosclerosis and heart attacks. Green and white tea contain especially high levels of antioxidants. This literally makes a cup of tea good for the heart.

For a stronger immune system
Green tea, which has been recognised as a healing agent and a beverage for roughly 3,000 years in China, rose quickly in popularity because of its many positive effects and its unique flavour. Imbalances in the body can result in the creation of “free radicals”, which attack cells and can damage the health. As shown by many studies, the antioxidants contained in green tea neutralise these free radicals and strengthen the immune system.

For healthy cholesterol levels
High doses of black and especially green tea can significantly cut cholesterol levels – LDL cholesterol (low density lipoprotein, considered a major risk factor in heart attacks and strokes) by as much as 16%. A Chinese study came to this conclusion, surprising even scientists. This proves that tea can help lower cholesterol levels.

For sufficient fluid intake
Drinking enough, at least 2 litres a day, is essential for maintaining physical and mental health. Tea drinkers have an easy time covering their daily fluid intake needs, and also getting a good supply of vitamins and minerals. Black and green tea have no calories, refresh the body and mind and taste good. That makes them ideal thirst quenchers.

For firm, healthy skin
The UV radiation in sunlight causes cell damage that can lead to premature skin ageing, sunburn and eventually skin cancer. For this reason, it is very important to protect against this dangerous radiation. The antioxidants in green tea protect against sun-related skin damage and help the skin to remain young and elastic longer. The minerals and vitamin C in green tea also help prevent wrinkling, and help sunburns to heal faster, for example.

For more energy
Thanks to the caffeine and polyphenols it contains, tea is not only refreshing, but also boosts concentration and supplies the body with energy. Unlike coffee, tea releases its caffeine into the body slowly, and has a stimulating effect for longer. Another advantage: The effect of the tea can be controlled by how long it steeps. When steeped for a short time (2–3 minutes), the tea primarily contains caffeine, while the polyphenol content increases after 4–5 minutes, causing the tea to have a calming effect on the stomach.
To lower the risk of cancer
Numerous scientific studies have shown that the regular consumption of large amounts of green tea (at least 10 cups per day) can significantly reduce the risk of cancer. The preventative effect is especially high for stomach and intestinal cancer. The protection in this case comes primarily from the antioxidants and vitamin C, which are abundant in green tea. Tea not only has a preventative effect, but can also inhibit the growth of existing tumours and the formation of metastases.

For a bright smile
Just one cup of tea per day can reduce the risk of cavities by up to 50%! This is above all because of the fluoride in tea, which strengthens the enamel and the teeth. The antioxidants in the tea also help to prevent cavities because their antibacterial effect inhibits the formation of plaque deposits. Cavities don’t have a chance!

It has been proven that drinking tea promotes good health.
Tea, especially green tea, contains highly effective antioxidants that neutralise so-called free radicals in the body and have a very positive effect on the human body and immune system. Numerous studies have shown that tea helps against high blood pressure and arteriosclerosis, lowers cholesterol levels and can even have a preventative effect against cancer. And another welcome side effect of drinking tea is the slowing of the ageing process in the body’s cells. Many important minerals such as fluoride, iron, zinc, calcium and potassium promote physical well-being and help you to stay healthy and fit.
