Hello! Here’s a book about The Components of Green Tea.

Do you ever wonder why green tea is popular nowadays?

You may have heard that green tea has many healthful benefits towards are body. Some said that it is the solution for some of our health problems and so on.

At first I am not convinced with the way green tea is introduced and how people describes how effective it is, until I discovered it for myself.

Now, here’s a guide on how green tea could be of great help and how to make it more effective. This also contains facts about green tea and many more.

People of the current generation chose green tea for its healthful benefits. Various researches were also made to prove the effectiveness of green tea. These fields of study have been presented in current years for the consumer’s familiarity with green tea. Even if these researches still lacks proof, it is slowly leading to an assumption that green tea really has huge effects in attaining a good health condition. Every element of green tea has its own part in making the herb so effective. Here’s an overview of the green tea’s components.

Chapter 1: Catechins and Polyphenols

Polyphenols are the most important antioxidant in green tea. It is divided into four main groups namely: phenol acids, flavonoids, stilbenes which are found in red wine and lignans in flaxseed. Catechins make up thirty percent of the dry leaf weight which is the biggest part of polyphenols in green tea. Due to the rising interest in the green tea’s health benefits, the inclusion of tea extracts in dietary supplements and functional foods was considered. However, there are some evidences which lead to the discovery of green tea as a cure and prevention to cancer is still conflicting. Green tea contains bioactive chemicals particularly catechins in which epigallocatechin gallate or simply Epigallocatechin gallate are greatly plentiful. These catechins and its byproducts contribute to the healthful effects of green tea as an herb.

Both polyphenols and Cathechins are useful scavengers of responsive oxygen group and indirectly functions as antioxidant through its effects on transcription features and enzyme activities. The rapid and extensive breakdown of Catechins emphasizes the significance of representing their antioxidant activity. In humans, temporary transient rises in an antioxidant ability of plasma which was demonstrated following the ingestion of green tea and other catechins. The impacts of tea were visibly seen on animal models but the data present in humans are still limited. Larger human researches in testing the effects of tea catechin intake are also needed. Catechins are tannin unique to green tea because the mixture of black tea procedure decreases its presence in black tea. Catechin is characterized as a powerful water soluble polyphenol and antioxidant. Some kinds are present in the plant world. There are about two thousand flavor structures called flavonoids known.

Catechins belong to the group. Green tea is derived from fresh and unfermented tea leaves. The oxidation of this component is limited but it serves as an antioxidant. According to researchers, catechin is beneficial because it easily attach to amino acids, opposing bacteria from staying to cell walls and disables their capacity to break them. Viruses on the other hand, have a peg on the topmost part and have the ability to stick to cell walls. The green tea catechin stops viruses from causing damage. It responds with toxins-made harmful bacteria and few types of metal. Catechin found in green tea overtakes Vitamin C and beta-carotene in hunting the radical of alkyl peroxyl for about ten times. Green tea polyphenols are stronger than any other vitamins such as C and E.

Catechins’ Advantages:

• Stops the development of cancer by removing free radicals
• Blocks aging
• Links with cholesterol, captivate and oppose it
• Reduces level of cholesterol and avoids bad cholesterol brought about by oxidation
• Inhibits various diseases such as heart attack, arterial sclerosis, brain strokes, thrombosis etc.
• Controls high blood pressure

• Stops enzyme functions that leads to sugar digestion and absorption
• Prevents diabetes
• Restrains collection of platelets that causes thrombosis and other diseases
• Combats viruses and bacteria to prevent cavities, influenza and food poisoning
• L with substances and averts foul smell

• Cleanses the body by dissolving harmful substances and heavy metals Polyphenols’ Benefits
• Certain necessary types of polyphenols like resveratrol, flavones, isoflavones and flavonoids are proven to have anti-aging components. These types are also believed to be effective as an anti-inflammatory and in enhancing the immune system. • Nearly all of the polyphenols are considered as antioxidants, and being one, they can deactivate the greatly volatile free radicals and reduce their harmful influence on the body organs, cells and tissues in particular.

• Free radicals are usually held responsible for causing cellular destruction, which is related with aging. So being an influential form of antioxidant, they can delay the aging activity. • Additionally, polyphenols can be revitalizing to the immune system. A powerful immune system is necessary for reaching the state of being healthy and preventing inflammations and other ailments. • Polyphenols could greatly help in the enhancement of the blood’s circulation and making the central nervous system vigorous making the body less prone to heart-related ailments. •

• Few kinds of polyphenols such as resveratrol are proven to be efficient in commotions which are anti-tumor. These types of polyphenols are capable of preventing certain types of cancer from developing. • A raspberry which contains polyphenols reduces the possibilities of bone loss. The main cause of a bone disease called osteoporosis is known as bone loss. • The catechins which are a component of green tea, particularly polyphenols are very efficient as a weight loss agent. The concentration enables the body to eliminate a larger quantity of calories and fats.

• An additional type of polyphenols, isoflavone could be helpful in coping with the signs of menopose. Isoflavones are bounty in substances like soy products. Polyphenols could still possess other healthful characteristics even though some of these advantages are still under further researches until now. An efficient method in getting the advantages of these substances is to add in quantity of foods sufficient enough to contain polyphenols. Yet, this technique must only be performed with the guidance of an expert because too much intake can be dangerous to the body. Furthermore, it is a must to maintain a vigorous diet which is bounty in fruits and vegetables and could give you a great amount of important nutrients needed by the body.

Chapter 2: Vitamin A

Vitamin A or Retinol is a vitamin which is fat-soluble in nature and it is usually found in animal foods. Vegetables and fruits contain carotenoids which functions as a great source of carotenes that is converted into vitamin A. Vitamin A is necessary for a person’s health and is particularly rich in liver, some fruits and vegetables.

Vitamin A’s Advantages:

• Resistance
Aside from reinforcing “entry points” into the body of humans, like mucous membranes, respiratory, the lining of the eyes, urinary and intestinal tracks, it is likewise necessary for white blood cells known as lymphocytes that battle against viruses in our body. Vitamin A enables us to have a strong immunity.

• Eyes

When converted into the form of a retinal, Vitamin A is essential for vigorous eyes. It enables the eye to determine between light and dark more effectively leading to the further development of night vision. In addition, Vitamin A combats against ocular diseases such as cataracts and glaucoma.

• Bones and Teeth

Vitamin A efficiently upholds vigorous teeth and bones when transformed into retinoic acid. A substance called dentin involves vitamin A in order to form the strong layer of substance inside our teeth, thus guarantees its strength. Moreover, vitamin A replaces damaged tissue to assure vigorous bones and teeth. • Urinary Stones

When stones are formed, dense fragments in the urinary system called urinary calculi causes discomfort, nausea and vomiting. Vitamin A creates calcium phosphate, an inorganic compound inside the body that stops the development of urinary calculi.

• Cancer

Vitamin A combats cellular rust, commonly known as stress inside our body. Being an antioxidant, it defends us from various health problems like cancer.

• Skin

Vitamin A’s antioxidant behavior combats free radicals that destroy the skin by oxidative stress. The skin is not only armored from ordinary dryness but likewise hardens the epidermis into a dense substance that comprises the hair and nails, a skin ailment which is particularly red and itchy called psoriasis, acne and wrinkles by preserving the moisture content.

• Reproductive System

Vitamin A is necessary for both female and male reproductive course. Vitamin A also functions in:


In the process of vision, the function of Vitamin A is precisely associated to the retinal form. The isomerization of retina provokes a nervous indication along the optic nerve to the visual center of the brain.

Gene transcription

In the retinoic acid form, vitamin A takes part in gene transportation. When retinol has been used by a cell, it can be dissolved to retinol dehydrogenises and then retinal can be dissolved into retinoic acid. The transformation of retinal to acid is a permanent pace, meaning that the manufacture of retinoic acid is strictly implemented, because of its motion as a ligand for nuclear receptors.

Side Effects of Vitamin A

If Vitamin A is taken at an amount less than ten thousand units a day, it could probably be safe. A number of systematic studies indicate that too much Vitamin A intake could contribute to a higher possibility of having certain diseases like hip fracture and osteoporosis, mostly for the elderly. Vitamin A supplements are not normally intended for individuals who eat plenty of fruits and vegetables rich in vitamin A together with low-fat foods.

Consuming huge quantity of vitamin A for a long period of time might trigger vital disadvantages such as anorexia, mental charges, irritability, excessive sweating, and several other discomforts.

Higher amount of vitamin A intake could bring a person lot of disadvantages than the advantages itself. Studies show that large amount of vitamin A intake could contribute to death risk and several other vital effects.

Vitamin A could also be prescribed to children but a reasonable quantity is strictly advised. Once the amount of intake is higher than what is advised, the child could experience vital disadvantages like sleepiness, diarrhea, vision impairments and other disorders. The quantity of vitamin A prescribed for children depends on their age: For children up to 3 years of age, not more than 2000 units daily For children ages 4 to 8 years of age, not more than 3000 units daily For children ages 9 to 13 years of age, not more than 5700 units daily For children ages 14 to 18 years of age, not more than 9300 units daily

Safety Measures
Pregnancy and breast-feeding

Vitamin A is probably harmless for pregnant or breast-feeding women if intake is within advised quantity of not more than ten thousand units daily. Bigger quantities could be harmful. Vitamin A can contribute to the development of birth imperfections. It is necessary for pregnant women to observe their intake of vitamin A coming from different resources throughout the first three months of pregnancy. Classifications of vitamin A are originated in several foods including animal products, primarily liver, some fortified breakfast cereals, and dietary supplements. Too much alcohol intake

Consuming alcohol could greatly trigger the vital disadvantages of vitamin A on our organs especially on our liver. Type V of hyperlipoproeinemia A particular kind of high cholesterol: Type V hyperlipoproteinemia may add risks of vitamin A toxins. If a person has this kind of ailment, he or she is advised to avoid intake of vitamin A.

Liver ailments

Excessive intake of vitamin A could deteriorate the condition of liver diseases. Likewise, it is also not advisable to consume vitamin A with this type of ailment.

Chapter 3: Dietary Fiber

The health benefit of a nutritious diet which contains enough dietary fiber is easy to distinguish. All at once, the health risks of fiber shortage is becoming mutually obvious. Dietary fiber (can be spelled dietary fibre) is the complex part of plant foods having two main parts: • Soluble also known as prebiotic or viscous fiber is a component of dietary fiber which is promptly distilled in the anus into the gases and physically active result. • Insoluble fiber is a component of fiber that is metabolically motionless, absorbing fluid as it moves across the digestive system relieving excretion. Dietary fiber acts by changing the kind of contents of the gastrointestinal zone and by altering the way other nutrients and chemicals are being soaked up. Soluble fiber takes in water in order to be a jellylike, sticky material and is fermented by bacteria in the digestive tract.

On the other hand, fibers that are certainly insoluble are composed of loose activities and are sober. Lignin, a main source of nutritive intricate fibers, may change the outcome and breakdown of soluble fibers. Naturally, dietary fiber is composed of polysaccharides that do not have starch or thickeners just like cellulose, chitin and other constituents that makes up the plant itself. The word “fiber” is somewhat of a misnomer, since numerous kinds of dietary fiber are not really fibrous.

The food supplies of dietary fiber are frequently separated to what they predominantly give – soluble or insoluble fiber. Food of herbs consists of both kinds of fiber in different degrees, according to its characteristics. Benefits of eating fiber rich foods are the manufacture of the healthful mixture during the distillation of soluble fiber, and the insoluble fiber’s capacity through its inert hygroscopic properties to boost bulk, alleviate stool, and minimize transport time by means of intestinal tract.

Soluble Fiber Advantages:

• Soluble fiber decelerates digestion both in the small intestine and stomach. This contributes in slowing down the transformation of carbohydrates into a type of sugar called glucose, hence alleviates blood levels of glucose. The existence of fiber in carbohydrate-rich foods really lessens the glycemic index of that particular food. By decelerating the process of digestion in the stomach, hence pushing nutrients to devote additional time in the digestive area, soluble fiber may likewise expand the uptake of minerals and other nutrients in food.

• Soluble fiber develops a substantial gel in terms of contact with water in the digestive tract. This puffy-effect, associated to the deceleration of the process in the digestive system, thus increases a fullness sensation without increasing calories. Therefore fiber is an essential element in any healthy diet or weight loss treatment.

• Soluble fiber seems to lower the levels of blood cholesterol because the fiber connects with the bile acids and cholesterol in the digestive tract, stopping them from being taken up by the body.

• Soluble fiber might as well have cancer benefits. Altered citrus pectin, once nourished reduces the size of tumors. In a number of unidentified method, the pectin appears to meddle with cancer cells joining together to develop tumors.

Insoluble Fiber Advantages:

Dietary fiber is included in the entire part of foods which is originated from plants that our body does not disintegrate. These characteristics might cause the fibers to seem an unnecessary portion of our daily diet, yet dietary fibers truly contribute in achieving a healthful body. Insoluble fiber, being a type of dietary fiber is usually found in foods like nuts, whole grains and different kinds of vegetables. It is in contrast with the soluble dietary fiber since it remains whole even when it gets in touch with water and other fluids.

• Normal Bowel Movements

Since insoluble fiber is capable of remaining whole even if exposed in water, it does not develop a cream-like substance between your intestines. Rather, it increases the mass of your feces and decreases the possibilities of constipation. If your feces are wobbly and watery, consumption of insoluble fiber could contribute in making it firm by enabling it absorb water. You could also possibly lessen the risk of experiencing irritable bowel conditions with a regular intake of insoluble fiber.

Several studies propose that consuming insoluble fiber in a regular basis might decrease the possibilities of colon cancer through maintaining an ideal level of pH in your intestines and stops the bacteria in creating vital toxins inside your body. Conversely, opposing proofs propose that these fibers have no effect on cancer and eventually contribute to greater possibilities of triggering it. Consistent consumption of nutritious foods and having regular medicals tests is a way to ensure the health condition of your body.

• Vigorous Heart

If you don’t have any cardiovascular or heart-related ailments, a regular consumption of insoluble fiber could greatly help in reducing the probability of having these diseases. But, if you do have signs of these ailments, consumption of insoluble fiber could slow down the development of these types of ailments inside your system. Other studies also state that insoluble fibers could also be helpful to your heart in terms of lowering your blood pressure and decreasing the risks of blood clots.

• Normal Body Weight

When eating fiber-rich foods, it is necessary to chew the food at a lengthy time. Extending your mealtime because you need to carefully chew these kinds of food allows you to enjoy your meal and decreases the possibilities of overeating. Consumption of dietary fibers allows you to feel satisfied with what you eat for a longer period of time. Foods rich in dietary fiber have fewer calories which means that with insoluble fibers you can maintain an average weight for your body.

Proper Dose of Dietary Fiber
Based on several researches, the regular necessities of both women and men for dietary fiber are different, and alter as they grow older. For ages 50 and below
Women are advised to have a fiber intake of 25 grams daily
Men are advised to have a fiber intake of 38 grams daily
For ages 51 and above
Women are advised a fiber intake of 21 grams daily
Men are advised a fiber intake of 30 grams daily
Professionals in this field do recommend methods for people to include the prescribed dosage of dietary fiber into the food they are eating. Then again, in order to prevent diarrhea and other similar ailments, you must enhance your fiber consumption little by little weekly.

Chapter 4: Theanine

Epigallocatechin gallate.

Theanine also has important medical outcomes for innately soothing and concentrating the brain. This nutrient helps in balancing the brain which is usually flowing in a number of diverse tracks. In humans, studies regarding this matter are still incomplete but smaller researches have concluded to several anti-anxiety benefits too. Patients normally characterize the effects as gentle, yet beneficial. The calming property may also be helpful to those who are not certainly anxious, but cannot calm the mind before sleep at night time, and those who have neck muscle tension. Expectantly, its benefits of anti-anxiety would be more definite through further medical studies. Theanine can cure mostly those have previously taken profound anxiety medications. However, an immediate replacement is not directly recommended. The normal dose of theamine is a hundred to two hundred milligrams one to two times a day. One should be aware with any anti-anxiety supplements until complete possible side effects have been subject in controlled surroundings.

Animal researches show that theanine also brings effects which are nearly optimistic to the brain. It shields the body from an environmental neurotransmitter that lets signaling among nerves called excess glutamate. Excess glutamate can cause harm to nerve tissue if the quantity is not controlled well. Theanine also protective benefits to nerve cells when blood flow is lessened caused y a stroke or other ailments. Protecting the cells of the brain performs a significant role in diseases that contemporarily cause anxiety, like Alzheimer’s disease.

Cholesterol impaired by redness and swelling becomes more harmful to the body. Theanine can greatly contribute in the prevention of this damage. It is also proven to improve the efficiency of chemotherapy medicines in animal researches. As anxiety is frequently a result of cancer analysis, this is outrageously significant. In addition, theanine can ease anxiety caused by medication and accompaniment of chemotherapy.

By simply drinking green tea regularly, you can obtain the same benefits from medication and other treatments. A number of patients encounter a soothing effect by simply drinking a glass of green tea daily. Supposedly, the amount of theanine found in a glass of green tea is noticeably fewer than the capsule which contains more concentrated extract of theanine. Similarly, a person could not obtain the same benefit as those in 1 one or two capsules of theanine even with a lot of green tea intake. Green tea does have other several ingredients of great benefits, so the issue about the greater concentration of theanine on capsules than those in green tea should not suppress the consumers from enjoying a nice and refreshing glass.

There were few studies made to show the effect of merging theanine with other anti-anxiety treatments. A number of patients have tolerated the recommended medications for anxiety with theanine added. Patients on anti-anxiety treatments should continue the prescribed anti-anxiety medicines by their doctors. They must first consider the advice of a doctor if they would want to substitute green tea for their anti-anxiety medications. Theanine’s Health advantages:

Theanine, as a relaxing component of green tea is already recognized as a substance with positive effects against anxiety. It could also bring positive effects to heart diseases and various types of cancer.

When it comes to relaxing and stimulating the brain, theanine is very much reactive. The components of theanine helps calm the brain which is usually functioning in different fields. For human beings, studies are still limited and needs proof, yet few other experiments suggested that this theanine is effective in fighting against anxiety. Consumers characterize the effects as gentle yet beneficial. The relaxing characteristics can also help individuals who are not really anxious, but can calm the brain before sleeping and cure the neck’s muscle tension.

Animal-related researches suggest that theanine also have protective impression for the mind. It shields the body from too much glutamate. Glutamate is a neurotransmitter that lets nerve signaling inside the body. It is a chemical which can be harmful to nerve cells if excessive intake took place. Theanine also protects the nerve cells once the blood flow is reduced. Protecting the cells of the brain is significant in the prevention of various ailments like Alzheimer’s.

Once cholesterol is harmed by inflammation, it becomes more harmful to the body. With proper consumption of theanine, this harmful condition could be prevented. Theanine also improves the efficiency of different kinds of cancer treatments. This is very significant since anxiety often caused by cancer treatments.

Theanine is much effective in supplement form or once combined with green tea. Optimistically, the advantages of theanine against anxiety could then be elaborated with further studies. It can also help individuals who previously underwent anti-anxiety treatments. However, sudden intake without the prior notice from the professionals is not advisable. Some theanine supplements also needs supervision from experts.

The usual theanine prescription ranges from one hundred to two hundred milligrams taken twice daily.

Chapter 5: Vitamin C

Ascorbic acid also known as vitamin C is an important water soluble nutrient for all creatures. Parsley, papaya, oranges, strawberries and bell peppers are example of foods that are enriched with vitamin C.

A requirement for a series of essential metabolic responses in a lot of plants and animals is an ion of ascorbic acid called ascorbate. It is internally created by almost all living things even though distinguished group of mammals such as chiroptera and anthropoidea are not included. Birds and fishes are also incapable of manufacturing ascorbate internally. Those organisms that do not internally manufacture ascorbate are required to have a regular intake of vitamin C which is included in their diet. In humans, scurvy disease is developed when there is a lack on ascorbic acid intake. It is also used commonly as a food preservative.

Ascorbic acid is entirely an ascorbate L-enantiomer while the D-enantiomer, ehic is considered as a counterpart has no biological importance. Both types almost have the same structure of molecules. L-ascorbate, being a firm agent of reduction, brings its function and is transformed into an oxidized form called L-dehydroascorbate. Then, L-dehydroascorbate would be reduced back to its original form in the body by glutathione and enzymes.

Semi-dehydroascorbic acid is made during this process. Free radicals of ascorbate badly respond with oxygen and therefore a superoxide is not formed. Instead of a superoxide, two radicals of semi-dehydroascorbate will respond resulting in the formation of a dehydroascorbate and an ascorbate. Glutathione on the other hand, converts dehydroxyascorbate to its base form which is ascorbate. Glutathione existence is significant because it saves ascorbate and leads to the improvement of the blood’s anti-oxidant capacity.

Benefits of Vitamin C or Ascorbic Acid

• Immunity

Researches had proven that toxicity of lead can bring developmental and behavioral problems like learning disorders and IQ impairment for children. As for adults, they may suffer from high blood pressure and kidney disorders.

• Cataracts

For the eye to function properly, ascorbic acid is necessary for its lens. An inadequate amount of ascorbic acid in the eyes can cause cataracts. Cataract is an eye disorder in which causes a blurry vision. A high amount of ascorbic acid allows you to lessen the possibilities of cataracts by
regulating blood flow to the eye.

Chapter 6: Vitamin E

Vitamin E could be characterized as a fat-soluble nutrient necessary for our body to function accurately. It effortlessly connects to fat, simply transporting it throughout the body. Appropriately, it is necessary to have an adequate amount of fat in your diet. The body has the ability to keep fat-soluble vitamins including vitamin E. Vitamin E is considered as a part of tocopherols.

Vitamin E advantages:

It is very efficient in eliminating various kinds of skin scars and it can promote a younger looking skin. 2. a lot of advantages of Vitamin E are observable because of its antioxidant nature. Eventually, free radicals are developed during the usual body digestion. The body acquires numerous toxic wastes through various ecological elements such as pollution. In this instance, oxidation between free radicals can eliminate fats. When this happens, vitamin E would be able to divert free radicals, leading to the prevention of chain response to lipid devastation. 3. Several advantages of vitamin E have been proven throughout time. It is incredibly beneficial as a cure or prevention for menstrual cramps, brain ailment, eye irritation, asthma, rheumatoid arthritis and other cardiovascular diseases.

4. Lots of people similarly believe that Vitamin E is essential especially in instances of Alzheimer’s and other similar ailments since as we get older, our body becomes feeble. 5. Several benefits of vitamin E can likewise be felt since it aids to lessen the danger of cancers like breast and prostate. Some people say that vitamin E could help in restraining pre-oxidation of lipids in blood whether a person is a smoker or not, without distressing the distillation of plasma lipoprotein. Lipoprotein with low concreteness helps in transfer of cholesterol and vitamin E in the bloodstream.

6. People who are experiencing cataracts benefits in vitamin E. Cataracts are classified as a disorder in the eye lens which leads to a blurred vision with a threat of being blind usually encountered by old people. Researchers have proven that frequent intake of vitamin E leads to prevention and cure of such diseases. • Vitamin E deficiency can lead to Abetalipoproteinemia. It is a unique ailment caused by low intake of dietary fiber and vitamin E which leads to a series of health problems such as retinal degeneration, muscle weakness and other diseases.

Vitamin E Disadvantages:

Once directly used on skin or swallowed, vitamin E could be harmless for those individuals who are physically fit. Several individuals does not undergo vitamin E’s disadvantages because they are using it according to the prescription of a professional. The normal dosage of vitamin E is usually fifteen milligrams.

Otherwise, vitamin E could also be harmful if the regular intake is too excessive. Individuals who have ailments like diabetes and cardiovascular disorders are not advised a vitamin E intake of four hundred International Units and above. Several studies show that excessive intake of vitamin E may cause vital effects or even death.

Hemorrhagic stroke is a disorder that has vital effects on an individual’s mind which may cause bleeding and other fatal conditions. The possibilities of having this kind of disorder are being increased with wrong vitamin E intake. Vitamin E intake can increase the possibilities of this stroke by twenty-two percent once taken in three hundred to eight hundred international units a day. On the other hand vitamin E could be advantageous in decreasing the possibilities of having another kind of stroke known as the ischemic stroke.

Inconsistent facts are also present regarding the capability of vitamin E in increasing the possibilities of having prostate cancer. Studies show that excessive intake of various vitamins together with an isolated intake of vitamin E could definitely contribute in acquiring prostate cancer especially in men.

Excessive intake could also contribute in developing fatigue, bleeding, stress, diarrhea and other fatal conditions.

Safety Measures:
Pregnant and breast-feeding individuals

Once vitamin E is taken in a correct amount prescribed by an expert, it could be harmless especially for pregnant and breastfeeding individuals. Vitamin E medications could be fatal if taken in the pregnancy’s first three months. Rather, this research is yet to be proven. It is better to consult an expert individually for secure health condition.


If an individual is about to undergo this type of heart surgery, he or she is advised to stop his or her vitamin E consumption or consult a health expert. This is because some theories suggest that vitamin E could be a hinder to this kind of heart surgery and may delay the process of curing. Lack of vitamin K

Cancer of Neck and Head

Vitamin E may contribute to higher chances of having these types of cancer. Excessive vitamin E intake should be avoided. It is advised not to take medications of vitamin e with four hundred international units or above in a day.

Chapter 7: Fluoride

Fluoride is stored in the leaves of particular tea plants. As a whole, the primogenital leaves of tea are the ones who have the greatest amount of fluoride. Majority of the leading teas utilizes the bud particularly the youngest leaves of the tea plant. A lower class of tea called brick tea is derived from the oldest tea leaves and is usually has a high fluoride concentration. In contrast to brick tea, green tea is mostly similar to those supplements that are suggested for the inhibition of cavities. Hence, everyday ingestion of one liter of green tea would be too much compared to what is recommended by professionals for dental health.

Fluoride is a type of substance particularly a mineral which normally constitutes a number of food and fluids. Minerals are continually added to and lost from the enamel level of your teeth daily. This gain and loss are done by means of two methods namely re-mineralization and demineralization. The loss of minerals from the enamel layer of the tooth caused by sugars and bacteria found inside a person’s mouth is called demineralization. On the other hand, demineralization happens when phosphate, fluoride, and calcium which fall under the minerals category are left behind the enamel layer from fluids and other foods eaten. Demineralization should be in proportion with re-mineralization to inhibit the gradual damage of teeth that may eventually lead to loss.

Fluoride helps in the prevention of tooth damage through maintaining tooth resistance from damage causing acids brought about by sugar, plaque and bacteria inside an individual’s mouth. It provides protection against tooth decay. Fluoride becomes integrated into the growth of permanent teeth demineralization impossible at the age of six. Therefore, tooth decay is more prone to children. Another function of fluoride is to help quicken the process of re-mineralization and interrupts the production of acid in previously broken teeth of a person.

Fluoride is dangerous when …

• Dry state of the mouth

Several medications and ailments like Sjögren’s syndrome cause a person’s mouth to be dry. A dry mouth increases the risks of having tooth decay. The inadequate quantity of saliva contributes to acid neutralization problems including the swallowing of food particles.

• Gum disease

Gum disease or gingivitis in other words is a gum disorder which lets both your tooth and tooth roots more prone to bacteria which increases the possibilities of having tooth decay. • Frequent cavity history

You might take advantage mostly of additional fluoride if you have one cavity yearly or even every other year.

• Presence of braces

This kind of medication and procedure can put teeth in great danger of decay at a certain area wherein the braces congregate with the main structure of the teeth.

Green tea possesses sterile properties which are helpful in killing bacteria that produces plaque on your teeth. Several studies show that risks of gum disease could be prevented for every glass of green tea that you drink because green tea is composed of a reasonable amount of fluoride which is very helpful in fighting against cavities.

Fluoride’s pieces of information

• Ninety-seven percent of the western part of Europe chose to have water with no fluoride content. • Water has fluoride content for the prevention of cavities which causes the tooth to decompose. • Fluoride is more efficient if “not” swallowed since its advantages has a great effect on the outer portion of the teeth. • Infants are not advised to be exposed water with fluoride content. It is proven that infants who are exposed to water-containing fluoride are more prone to a disease called dental fluorosis and other teeth disorders.

• Being a healthy substance, fluoride is normally put on water. In some areas, it is more preferable to put fluoride on other substances such as mouth wash and toothpaste, aside from water because it fluoride-containing water could be harmful especially to infants.
