Vitamins and Minerals In Tea

by Elena Popec 17. May 2010 07:31

Due to the variety of minerals, vitamins and other elements contained in tea, this drink improves health, relieves fatigue, strengthens the immune system and has an overall tonic effect on the body.

Mineral substances contain in green tea leaf and in finished products, it constitutes about 5-6% of dry matter. Among them are the following: potassium, phosphorus, calcium, magnesium, sulfur, iron, manganese, fluoride and others. With the aging of the plant total number of minerals increases, while the most valuable part of the soluble reduces. Only the components of relatively small molecular weights which are infused with hot water give a specific accent to the tea infusion. Between the quality of tea and the content therein of soluble mineral substances there is a direct link.

The potassium content in the tea leaf is 50-60% of all mineral substances and depends on the mineral nutrition of plants. This compound plays a very important role in the livelihood of tea tree; it is given a great importance in the synthesis of carbohydrates and proteins, and in the general metabolism. Potassium is very important to the human body; it prevents muscle cramps and regulates fluid and electrolyte balance.

Another important mineral is located in the tea - phosphorus. Its content ranges from 15-20% of weight of all mineral substances in tea. The properties of the finished product depend on its quantity. The two top leaves and a bud have higher content of phosphorus compare to the lower coarse tea leaves and stems. It is known fact that phosphorus is needed for the human body for normal functioning, as part of the nervous, brain tissue and bones.

Despite the slight content, copper and iron play an important role in plant’s life. They are part of some physiologically important organic compounds, such as enzymes. Another, small in content, but necessary for redox processes, is manganese. Its share is approximately 1-4%. Due to the iron content, tea has a beneficial effect on the human blood, as well as a good means for the prevention of various vascular diseases. In addition, the body needs iron to transport oxygen.

The complex experiments revealed effects of the duration of brewing tea and the quantity of the tea leaves on the degree of content in the drinks of various trace elements. Adding citric acid increased the yield of all elements, except copper. In the end, it was found that  a tea drink satisfies the daily requirement of zinc, copper and manganese at 1, 2 and 50% respectively.

Now let us turn to vitamins contained in tea. This is mainly vitamins B complex and C. The tea shoot has the following B complex vitamins: B1 (thiamin), B2 (riboflavin), B3, and B5 (PP), B6, B12 and P. Since these compounds are very stable, in the processing they are almost completely transformed into finished products. Content of vitamin B1 is small - an average of 0.3 - 10 mg per 1 kg of dry tea leaves. In the body this vitamin (B1) regulates metabolism of carbohydrates, amino acids, fatty acids, has versatile affect on the function of the cardiovascular, endocrine and central nervous system. Vitamin B2 has positive effect on the skin and mucous membranes, the health of the liver. The most important is the presence in tea of vitamin P. One of its most important properties is the strengthening of the capillaries of the plant. During the technological processing of raw material quality and quantity of the vitamin are undergoing significant changes. Its content is reduced from 20-25% in green tea to 8-15% in the final. Along with others, the tea contains vitamin PP that is important for normalizing the higher nervous activity, the functions of the digestive system. It also affects the cardiovascular system, in particular, expanding the small vessels.

Tea leaves are rich in Vitamin C. Gentle leaves contain approximately 2-3 times more of this vitamin than the coarse. In the process of refining its amount is sharply reduced, especially during the fermentation and drying. This vitamin is essential for strengthening the immunity of a person, it reduces the risk of infections, but also useful for the prevention of osteoporosis and periodontitis (inflammation of the periodontal tissue, i.e. tissue surrounding the tooth root). Tea fluoride also provides the beneficial effect on teeth. This element exists in tea leaf as anion. Fluoride anion produces various fluoride compounds and covers the surface of teeth to prevent bacterial attack. Just wanted to point out that tea is very useful for vision, because it contained β-carotene and other elements, strengthens blood vessels.

 

Health Benefits of Tea

Health Benefits

Were you aware that our nation drinks approximately 165 million cups of tea daily? Millions of people love the taste of tea, but many of us are not aware of the healing powers tea can actually give us.

Tea is not only delicious, it can also help prevent High Blood Pressure by controlling angiotensin, which eventually leads to high blood pressure, according to health experts.

Studies have shown that drinking tea can also provide us with protection against cancer, heart disease and it can also aide in preventing memory impairment conditions such as Alzheimer’s.

 

Healthy Antioxidants within Tea

Flavanoids generally found in vegetables and fruits; contain powerful antioxidants such as Vitamin C and E.  So, one cup of tea actually contains twice as many of these Flavanoids as one apple.

You often hear about the importance of consuming fruits and vegetables, but rarely are you encouraged to drink tea - maybe more of us should.

Consuming tea and its healthy antioxidants provides us with antiviral, antibacterial, anti-inflammatory, and antiallergenic benefits. 

Drinking tea also has the benefit of helping improve concentration thus improving performance. Concentration is improved due to the caffeine that is within tea. The caffeine makes you more alert and focused.

Tea is also a natural source of fluoride; therefore it helps to keep teeth and gums healthy.  Because tea contains this natural source of fluoride, it can help prevent certain gum diseases and tooth decay. 

 

The Power of Green Tea

The Chinese have been using the healing effects of Green Tea for centuries, 4,000 years in fact. Only in the past 20 years other parts of the world began to take notice of this herbal treatment for headaches, depression, and beyond.

In 1994, a study was conducted that revealed Green Tea could possibly reduce esophageal cancer risks by 60%. Numerous other studies have been performed as well to establish the health benefits of consuming Green Tea and to learn why the herb is so healthy.

Clinical studies conducted over the years have found that Green Tea, or the herbs that create Green Tea, contain powerful antioxidants. Many believe that it may help prevent cancer cell growth, but to also selectively eliminate cancer cells. This is especially amazing because the powerful herb does not attack the healthy cells around the cancer cells.

Green Tea can also be efficient in lowering the bad cholesterol, LDL, levels while boosting the good cholesterol, HDL, levels.  By doing this, Green Tea is improving the ratio of good to bad cholesterol and possibly helping to prevent the onset of heart disease.

The Chinese have shown us many healing teas, but Green Tea is by far the best healing tea that has been introduced to us. Because Green Tea leaves are steamed, they are able to hold on to their potent antioxidants.

Green Tea as well as Fruit Blends, Rooibos, Herb Blends and Ayurvedic are fairly inexpensive and is well worth the cost for all of the potential healing effects and preventative abilities it has.

 

Drink Black Tea for a Healthier You

Black Tea, although made from the same plant as white and green tea, is almost completely different. Black Tea, unlike Green Tea and White Tea, is processed and fully oxidized.  Although from the same plant, what happens to the tea leaves after picking is what sets the three apart.

Black tea does not hold as many health benefits as Green Tea, but it still has retains enough to make it a smart choice for drinking. One reason why it’s considered the smart choice is simply because most studies have been only conducted on green tea. This is because it is the most consumed tea in the world.

The antioxidants in Black Tea can help protect against free radicals damage that generally leads to disease. Some properties of Black Tea have been shown to slow the growth of cancer cells but not effecting the growth of healthy cells.

The fact that the properties in the tea have the ability to selectively target the cancer cells and not the healthy cells is truly amazing.

 

Drinking Tea May Slow Down the Aging Process

Drinking Black Tea has also been said to slow down the aging process. Look at the anti-aging lotions and serums on the market today and you will find that many contain tea leaf extracts. Black Tea also is known to help rev up metabolism and fat burning. This is even more so when used in conjunction with caffeine and exercise.

To lower your LDL, bad cholesterol, studies have shown that drinking Black Tea is beneficial in doing so as well as helpful in increasing your HDL, healthy cholesterol. Drinking tea can help balance the ration of good and bad cholesterol and help to ward of heart disease.

If you are diabetic, drinking tea can aid in lowering glucose levels. Lowering your glucose levels will also lower your risk of conditions brought on by diabetes such as cataracts. Start drinking tea today for a healthier you tomorrow!

 

Rooibos

Rooibos in Afrikaans is translated as “red bush”.  This has a very sweet taste and it is frequently used as a base tea to blend tea.  It is rich in antioxidants and it is caffeine free. Here are a few health benefits of Rooibos:

 

·         Contains a host of vitamins and minerals such as copper, potassium zinc, calcium, potassium and manganese.
