Green tea has a reputation for having tremendous positive effects on your health but what are the reasons behind it? This article will help explain the reasons. What are the compounds included in green tea that makes it so good for you? Below is a list of what the most significant ingredients are, and how they benefit your health:

Polyphenols - a powerful-acting antioxidant, which is naturally occurring and most responsible for the color, flavor, and taste in fruits, vegetables, seeds and types of plants. The benefits include lowering the risk of heart disease, cancer and other types of diseases. The properties in polyphenol can be such that they serve as an anti-oxidant, anti-bacterial, anti-inflammatory and anti-allergenic.

Catechins - a class of polyphenol, commonly in high doses in green tea. Benefits include anti-carcinogenic, lowering of cholesterol and LDL levels, prevention of high blood pressure, prevention of red blood cell clots, prevention of allergies, anti-biotic acting functionality, and improvement of digestion and elimination of body odor.

Flavonols - another class of polyphenol with anti-oxidant properties. Benefits include the trapping of free radicals and peroxides, and the prevention of destruction of body tissue. Works in conjunction with vitamin C, helping to strengthen the walls of blood vessels.

Glycosides - complex sugar. Prevents blood sugar increase.

Carotene - compound which is organic and found in most orange and yellow vegetables and fruits. Helps to make body produce vitamin A. Benefits include prevention of oxidation, improves immunity and has anti-carcinogenic properties.

Flouride - mineral which helps strengthen tooth enamel, thereby preventing tooth decay.

Caffeine - diuretic. Benefits include speeding of nervous system, prevention of asthma, increase in metabolism.

Vitamin C - vitamin which helps fight against infections and helps the immune system.

Vitamin E - vitamin which helps in prevention of breakdown of body tissues. Also helps with infertility and is anti-carcinogenic.

Vitamin B - vitamin which helps in metabolism, maintenance of healthy skin and muscle tone, enhancement of immune and nervous system, promotion of cell growth, and reduction of certain cancers.

Zinc - mineral which helps in prevention of skin inflammation and helps in maintenance of immunity level.

Selenium - mineral which helps in prevention of oxidation and heart muscle deterioration.

Westerners have recently rediscovered the green tea. It has its origin in China; the Chinese believe that green tea has the ability to prevent many hazardous diseases, and even treat symptoms of others. This belief has now passed on to the western world, through word of mouth, and of course, the most well-known promotional tool in the world: the Internet. The west is now slowly adapting to the taste of green tea instead of black tea; not everyone likes the idea of 'green' tea, but the color is paler, not green, and the flavor is crisper. Green tea is made from a leaf called Camellia Sinensis, most commonly. These leaves do not require a high amount of oxidation and which makes green tea a good source of the antioxidants known as “Catechins”.

Antioxidants & Catechins

Antioxidants are agents that fight free radicals in the body. Free radicals can cause cell damage and a number of other diseases, --free radicals, are abnormal foreign agents, in some cases, and they are linked to the development of various kinds of cancer. Catechin in green tea is what gives it the strong taste and smell. Catechin also has the capability to move up to infiltrate our body's natural digestive system. It once absorbed by our digestive system, it’s filtered through the blood, where it eventually, reaches our retina, and eyes. The catechins then protect the eyes and reduce the occurrence of eye diseases. Research has been done on whether or not green tea can prevent glaucoma; the findings are pretty amazing. Glaucoma is a disease that can cause loss of eyesight, visual impairment, and even permanent blindness.

How it Works

An experiment was conducted on mice to prove that green tea can fight eye ailments. The tiny animals were fed green tea orally on a regular basis, and then their eye tissues were analyzed. The analysis revealed that the retina absorbed the highest number of catechins. The antioxidant lowered the harmful oxidative pressure in the eye and the effect lasted for about twenty hours. Many people are also aware of green tea's effect on weight loss; everyone seems to be jumping on some kind of green tea fad diet. Well, these diets aren't just trendy, 'here today, gone tomorrow', weight loss schemes. When used in your regular diet program and health regime it is extremely beneficial. People who replaced coffee for green tea rarely come back to coffee.

Add Green Tea for a Healthier Future!

Because of its medicinal values in the last few years Green tea has become an important subject of scientific research and analysis. These studies have proven that green tea also has other medicinal effects and benefits that help in reducing or preventing some hazardous diseases like cancer. Even more studies have proven that green tea may be effective in the treatment of joint diseases, like rheumatoid arthritis, or impaired immune disease and other serious illnesses associated with the liver. A cup of green tea is a good refresher and pumps in a high amount of energy in to the system, --and don't forget, it tastes great too!

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.

 

Ayurveda is a Doctrine Of Life, Health, Endurance, and Equilibrium Part 1

by Elena Popec 26. April 2010 13:05

In the last decade, Ayurveda concepts have become very common and fortunately, made people think again about their health. Therefore, more and more people are beginning to be interested in Ayurvedic teaching. Many do not know that Ayurveda is much more than a massage with oils or an art of relaxation. Ayurveda is an ancient doctrine which arose in the traditional Indian philosophy and was first described in ancient Indian writings, the Vedas. The term "Ayurveda" comes from Sanskrit words "Ayur" meaning "life" and "veda" - "knowledge", "doctrine". Thus, this concept can be translated as "the science of life." In the heart of yoga and meditation is also Vedic knowledge. Ayurveda has survived primarily because of the revival of Vedic master Maharishi Mahesh Yogi, who opened the old knowledge to the modern world. For nearly twenty years of this vast topic of Ayurveda experts are engaged, as well as western doctors and scientists. The Ayurvedic doctrine is also described as an “integrated combination of the empirical doctrine of nature and philosophy” which focuses on the physical, mental, emotional and spiritual aspects which are necessary to human health.

Submission of a man in Ayurveda

Ayurveda considers not only the human body, but the unity of body, mind and spirit in their relationship with the surrounding world and nature. Each person is different from each other, physically and mentally. With Ayurvedic extensive and integrated examination of nature, human beings in nature and all that surrounds it, Ayurveda is the doctrine of Medicine, which focuses on the concern for the preservation of health. While modern medicine considers mainly a disease and its symptoms, thus engaging the body, not spirit, or analyzes the impact on the human body. The starting point of Ayurveda is different, finding the right balance, or rather the balance of the three defining concepts of Ayurveda, so-called Doshas.

- Vata (Wind, Air, Pneuma)
- Pitta (Fire and Water, Chole)
- Kapha (Earth and Water, Phlegma)

The essence of the Ayurvedic doctrine is that the Doshas should be harmoniously balanced and this can be supported with the addtion of certain spices.

Basic principles of Ayurveda

Everyone has a balance of Vata, Pitta and Kapha, which is constantly changing. Mental state, time of the year and day continuously affect the individual balance and the balance of Vata, Pitta and Kapha. This equilibrium is not constant, it changes all the time. One might say that human health constantly updates; therefore a human being is a self-regulating system. However, the ability of the organism to self-regulation can be exhausted. For example, this may occur because of high level of irritation, stress, malnutrition, or due to the fact that in our sometimes too loud world, the human being loses the ability to listen to itself, enjoy the silence and cognize the quiet force in itself. Or, in other words, one may lose the ability to appreciate the moment without having a special occasion to celebrate.  Initially, Ayurveda strives to create an environment in which it will be possible to avoid disturbances. Therefore, the teaching of Ayurveda is the guidance for the construction of life: food, drink, sleep, choosing a partner, and more. These instructions are given to man to have three doshas (Vata, Pitta and Kapha) in equilibrium. Thus, Ayurveda is a system of healing, which aims to maintain health. The slightest disturbance can lead to illness and disease. Conversely, small corrections in the style of life entail improvements. And, of course, according to the teachings of Ayurveda, everything that exists in the world can be used as a medicine.

Stay tuned for part 2 as we will examine the three Doshas.
