Caffeinated Drinks



What Is Caffeine?
Caffeine is a new web indexing system that provides 50 percent fresher results for web searches compared to Google’s previous index and it’s the largest collection of web content they’ve offered.  Caffeine was built with the future in mind.  It is built on a robust foundation that allows for an even faster and more comprehensive search engine that scales with the growth of information online, and delivers even more relevant search results.
You can now find links to relevant content much sooner after it is published.  Caffeine allows for indexing of web pages on an enormous scale.  Every second, Caffeine processes hundreds of thousands of pages in parallel.   Caffeine takes up nearly 100 million gigabytes of storage in one database and adds information at a rate of hundreds of thousands of gigabytes per day



Caffeine acts as a stimulant to the heart and central nervous system, and is also known to increase blood pressure in the short term, although there is no conclusive evidence of long-term effects on blood pressure.


The effects on blood pressure are most likely when caffeine is taken in excessive quantities or by highly sensitive people. In particular, people who are hypertensive (have habitual high blood pressure), are advised to avoid caffeinated drinks, while pregnant women are advised to limit their intake of caffeinated drinks to less than 300mg per day.
   Coffee
Coffee has been linked with a number of the risk factors for coronary heart disease, including increased blood pressure and high blood cholesterol levels. However, no relationship has been found between coffee drinkers and the likelihood of developing coronary heart disease.Coffee may be beneficial in some areas of health. Research has found that coffee may reduce the risk of developing gallstones, kidney stones and colorectal cancer.
It's difficult to suggest a safe limit for coffee intake because of the huge variation in caffeine content of different brands and an individual's sensitivity to the drug. People with high blood pressure and pregnant women are advised to limit their caffeine consumption.
For the rest of the population, there's no evidence coffee does any long-term harm. Caffeine does have a very mild diuretic effect, however, so try to include plenty of non-caffeinated drinks throughout the day as well.
   Tea
Tea does contribute slightly to our intakes of minerals, and it certainly helps to replace lost fluids, but the health interest in tea at the moment surrounds its potential role in lowering the risk of coronary heart disease and some cancers.
Tea contains antioxidant substances called flavonoids. These have been shown to help slow or inhibit the chemical reactions thought to take place during the development of coronary heart disease. So sup up
