Green Tea Diet

Obesity has become one of the major health issues in our society today. More than half of the American population is overweight or obese. As a result, diet and weight loss plans have become increasingly popular. But not all diet plans work. And not all of them are necessarily risk-free. A safer alternative for people wanting to lose weight are green tea diets.

About Green Tea

For thousands of years, green tea diet has been highly valued by the Chinese as an herbal and medicinal drink. It was believed that green tea diet was first discovered by the Chinese Emperor Shen Nung who was boiling water when the leaves of a nearby tree fell into his pot. The result was the first ever pot of green tea.

Like all three of the major Asian teas in the market, green tea comes from the plant called Carmellia sinensis. Much of the health benefits of green tea diets owe to the steaming method of making it. As opposed to black and oolong tea which undergoes full oxidization, green tea diet is only gently steamed, preserving the natural antioxidants in its original form.

The Health Benefits of Green Tea Diet

There are many health benefits associated with having a green tea diet. One of these green tea diet benefits is preventing cancer. Certain substances present in green tea diets are said to help in destroying cancer cells without harming any neighboring tissues. This substance in green tea diets is called epigallocatechin gallate or EGCG.

EGCG in green tea diets is also helpful in increasing the 24-hour energy expenditure of the body. A study on green tea diets conducted by American and Swiss scientists in the University of Geneva showed an additional increase of four percent in the body’s natural energy expenditure. People who were on a green tea diet were more likely to use up more fats than those not on a green tea diet.

Also, green tea diets are said to greatly help in lowering down cholesterol levels in humans. The study on green tea diets was conducted in China using 240 people with high cholesterol levels as subjects. These people were placed on a green tea diet of one capsule (equivalent to seven cups of green tea) or were given one placebo every day. After twelve weeks, those who were on a green tea diet dropped sixteen percent in their cholesterol levels.

Green tea diets can also be a potential cure to obesity. The catechin polyphenols present in green tea diets can delay the reaction of gastric and pancreatic lipases in the body. These enzymes are responsible for converting calories in the body into fats. By delaying these enzymes, green tea diets can therefore stop fat from being stored and prevent obesity in people.

Green tea diets contain substantial amount of caffeine that make it a mild appetite-suppressant. However, caffeine content in green tea diets is not as high as those found in other caffeine-based beverages, like coffee. Caffeine may be harmful for the body since an excess of it can cause heart palpitations, hypertension, and insomnia. Because green tea diets contain only very low levels of caffeine, there is no danger of experiencing these side-effects.

THE GENESIS OF SOIL.

Soil primarily had its beginning from rock together with animal and vegetable decay, if you can imagine long stretches or periods of time when great rock masses were crumbling and breaking up. Heat, water action, and friction were largely responsible for this. By friction here is meant the rubbing and grinding of rock mass against rock mass. Think of the huge rocks, a perfect chaos of them, bumping, scraping, settling against one another. What would be the result? Well, I am sure you all could work that out. This is what happened: bits of rock were worn off, a great deal of heat was produced, pieces of rock were pressed together to form new rock masses, some portions becoming dissolved in water. Why, I myself, almost feel the stress and strain of it all. Can you?

Then, too, there were great changes in temperature. First everything was heated to a high temperature, then gradually became cool. Just think of the cracking, the crumbling, the upheavals, that such changes must have caused! You know some of the effects in winter of sudden freezes and thaws. But the little examples of bursting water pipes and broken pitchers are as nothing to what was happening in the world during those days. The water and the gases in the atmosphere helped along this crumbling work.

From all this action of rubbing, which action we call mechanical, it is easy enough to understand how sand was formed. This represents one of the great divisions of soil sandy soil. The sea shores are great masses of pure sand. If soil were nothing but broken rock masses then indeed it would be very poor and unproductive. But the early forms of animal and vegetable life decaying became a part of the rock mass and a better soil resulted. So the soils we speak of as sandy soils have mixed with the sand other matter, sometimes clay, sometimes vegetable matter or humus, and often animal waste.

Clay brings us right to another class of soils clayey soils. It happens that certain portions of rock masses became dissolved when water trickled over them and heat was plenty and abundant. This dissolution took place largely because there is in the air a certain gas called carbon dioxide or carbonic acid gas. This gas attacks and changes certain substances in rocks. Sometimes you see great rocks with portions sticking up looking as if they had been eaten away. Carbonic acid did this. It changed this eaten part into something else which we call clay. A change like this is not mechanical but chemical. The difference in the two kinds of change is just this: in the one case of sand, where a mechanical change went on, you still have just what you started with, save that the size of the mass is smaller. You started with a big rock, and ended with little particles of sand. But you had no different kind of rock in the end. Mechanical action might be illustrated with a piece of lump sugar. Let the sugar represent a big mass of rock. Break up the sugar, and even the smallest bit is sugar. It is just so with the rock mass; but in the case of a chemical change you start with one thing and end with another. You started with a big mass of rock which had in it a portion that became changed by the acid acting on it. It ended in being an entirely different thing which we call clay. So in the case of chemical change a certain something is started with and in the end we have an entirely different thing. The clay soils are often called mud soils because of the amount of water used in their formation.

The third sort of soil which we farm people have to deal with is lime soil. Remember we are thinking of soils from the farm point of view. This soil of course ordinarily was formed from limestone. Just as soon as one thing is mentioned about which we know nothing, another comes up of which we are just as ignorant. And so a whole chain of questions follows. Now you are probably saying within yourselves, how was limestone first formed?

At one time ages ago the lower animal and plant forms picked from the water particles of lime. With the lime they formed skeletons or houses about themselves as protection from larger animals. Coral is representative of this class of skeleton-forming animal.

As the animal died the skeleton remained. Great masses of this living matter pressed all together, after ages, formed limestone. Some limestones are still in such shape that the shelly formation is still visible. Marble, another limestone, is somewhat crystalline in character. Another well-known limestone is chalk. Perhaps you'd like to know a way of always being able to tell limestone. Drop a little of this acid on some lime. See how it bubbles and fizzles. Then drop some on this chalk and on the marble, too. The same bubbling takes place. So lime must be in these three structures. One does not have to buy a special acid for this work, for even the household acids like vinegar will cause the same result.

Then these are the three types of soil with which the farmer has to deal, and which we wish to understand. For one may learn to know his garden soil by studying it, just as one learns a lesson by study.
