Much is being written about in the media about the growth of nutraceuticals (nutritional substances that provide greater health benefits than simply being nutritional) and people are exploring a great number of foods for these proposed health benefits. From Omega-3 fatty acids in seafood to resveratrol found in red wine, there are a great number of opportunities to enhance one’s health while simply eating or drinking something enjoyable. Green tea has come to the forefront of the nutraceutical movement for the many health benefits associated with its consumption. The American Institute for Cancer Research (AICR) has presented much evidence to the effect that green tea may prevent cancer, yet, interestingly, the Food and Drug Administration (FDA) continues to disallow any health claims to be associated with green tea for food labeling purposes. This may cause some confusion to tea drinkers in the U.S. Green tea it turns out is particularly rich in the powerful antioxidant epigallocatechin gallate, otherwise known as EGCG. While black tea is also a source of EGCG, it turns out that green tea contains far more than black tea. Why does this matter you ask? well, ECGC has been shown to inhibit the growth of cancer cells in the laboratory. While less consistent results have been shown in the general population, enough evidence is there to show that this powerful food is of benefit to one’s health. This lack of consistency is the reason why the FDA has not approved a health claim on green tea…. yet. Another property of green tea is that its consumption has been shown to lower one’s low density lipoprotein (LDL) cholesterol level, otherwise known as the bad cholesterol. It has also been shown to help prevent heart disease. Recent studies at the Medical College of Georgia have shown that green tea may help protect against autoimmune diseases as well. Essentially, the antioxidant EGCG helps to stabilize highly reactive molecules we call free radicals that damage blood vessels and increase the risk of heart disease, or alter the DNA in our genes, which can lead to cancer. It turns out the EGCG may also affect the enzymatic reactions and cellular signaling between cancer cells, which can slow the development of existing cancer. Why Green Tea? While all tea contains EGCG, green tea contains far more than other teas. The difference is that green tea is steamed before it can oxidize, while other tea types are allowed to oxidize partially or fully. Steaming the tea leaves while they are still green helps prevent the naturally occurring EGCG from breaking down during oxidation. Another substance mentioned in the news these days is the resveratrol content in red wine, which also has been shown to have similar properties. What makes this interesting is that French studies have shown that the the French have much lower incidences of heart disease than people living in the U.S., which has been correlated with red wine consumption. However it turns out that EGCG is approximately 50% more powerful than than resveratrol, therefore making green tea, by volume, a much stronger source of powerful antioxidants. There are also studies recently that have shown that the consumption of green tea can help the body burn more calories in those who drink it compared to people who do not (a property now being noted and exploited by a major soft drink manufacturer that shall remain nameless in this discourse). Green tea has also exhibited anti bacterial qualities, which has been shown to help prevent tooth decay in green tea drinkers. A Healthy Choice As you can see, as well as being tasty, green tea is an incredibly healthful beverage, with a great array of beneficial properties. While no magic cure that would allow a person to forsake all other methods for staying healthy, green tea consumption, as a part of a healthful lifestyle, may aid the body to avoid any number of diseases and illness from which we suffer. There are many ways to incorporate this incredible drink into your diet, and with no downside, there is no reason why everyone shouldn’t have a least one cup of this wonderful elixir every day. Drinking green tea is also another way to keep you body hydrated, so instead of reaching for a glass of water, take the time to make a cup of green tea. Your body will thank you in the end.

Zeleni čaj za zdravo mršavljenje Zeleni čaj dolazi iz Kine gdje ga poznaju još od davnina. Narodna medicina vjerovala je da zeleni čaj liječi skoro sve bolesti, od glavobolje, zubobolje pa do psihičkih oboljenja, recimo depresije. Danas je znanstveno dokazano ljekovito djelovanje zelenog čaja pa ga se preporučuje piti što više. Tajna zelenog čaja U zelenom čaju ima preko 300 sastavnica i upravo njihova kombinacija daje efikasne rezultate za zdravlje. Zeleni čaj je bogat polifenolima, osobito EGCG-om koji je snažan antioksidans. Zeleni čaj sadrži i kofein koji stimulira probavu. Količina kofeina je manja nego u kavi što je dobro jer se čaj može piti više puta dnevno bez da se unese previše kofein. Evo svojstava zelenog čaja koja mu daju titulu “čaja za zdravo mršavljenje” - jačanje srca i krvožilnog sustava - smanjivanje lošeg (LDL) kolesterola - ubrzavanje metabolizma - reguliranje razine šećera u krvi - davanje osjećaja sitosti bez suvišnih kalorija Ostala ljekovita svojstva su: - zeleni čaj usporava napredak raka, a može djelovati i preventivno (u jednom istraživanju na ženama one koje su pili čaj imale su manju vjerojatnost razvitka raka grudi od onih koje nisu pili čaj) - zeleni čaj pojačava kognitivne sposobnosti i sposobnosti učenja pa ga se smatra “zaštitnikom mozga”, može također spriječiti pojavu Alzheimerove bolesti - jača imunitet - sprečava pojavu karijesa - zeleni čaj i akne- djeluje dobro na ten, smanjuje prisutnost akni Jedno istraživanje pokazalo je da je dobro piti zeleni čaj prije tjelesne aktivnosti jer on stimulira izgaranje dodatnih kalorija. Ono što je važno dodati je i da zeleni čaj nema nuspojava. Jedina zabilježena negativna strana je nesanica i to samo ako se čaj konzumira nedugo prije odlaska na spavanje. Kako pripremiti zeleni čaj? Priprema je ovdje jako bitna jer se lošom pripremom mogu izgubiti korisna svojstva čaja. Nikada nemojte stavljati vrećicu čaja u kipuću vodu. Kipuća voda će uništiti svojstva čaja. Voda treba biti na temperaturi oko 75 C. Također, nemojte držati vrećicu predugo u vodi. To neće pokvariti ljekovita svojstva, ali će učiniti okus gorkim. Dvije do tri minute su dovoljne. Priprema - koristite jednu vrećicu čaja (2 – 4 grama) po šalici - zagrijte vodu da zakipi - pošto nije dobro ubaciti vrećicu u kipuću vodu pustite vodu 3 minute da se ohladi ili dodajte u kipuću vodu malo hladne - ubacite vrećicu i neka stoji u vodi 2 do 3 minute - izvadite vrećicu, po želji dodajte limun i med (nikako ne puno šećera, zeleni čaj ne smije biti previše sladak) Ledeni čaj Zeleni čaj pije se kao topli napitak ili kao ledeni čaj koji paše pogotovo usred ljeta. Kad radite ledeni čaj napravite veću količinu i spremite u hladnjak. Može se poslužiti s ledom i listom metvice za dekoraciju. Koliko ga dnevno konzumirati? Zelenog čaja ne možete konzumirati previše. Još jedno istraživanje pokazalo je da su muškarci koji su pili 10 šalica čaja dnevno (to je oko 300 mg polifenola) dobili rak 3 godine kasnije nego muškarci koji nisu pili zeleni čaj. Koliko ćete zelenog čaja piti to je individualno. Dobro ga je piti nakon obroka jer on ubrzava i pospješuje probavu. Dobro ga je piti ujutro umjesto kave i prije tjelesne aktivnosti. Zadajte si da svaki dan popijte barem jednu šalicu tog napitka i učinit ćete dobru stvar. Razlika između zelenog i crnog čaja Oba čaja rade se iz čajne biljke (čajevca). Razlika je u obradi, zeleni čaj radi se od svježih listova dok se crni čaj radi od fermentiranih listova. Fermentiranjem se gube ljekovita svojstva polifenola pa zato crni čaj nije toliko djelotvoran kao zeleni. Za kraj, gdje kupiti zeleni čaj? Zeleni čaj se nabavlja u prahu ili u gotovim vrećicama, a ima ga za kupiti u skoro svakoj trgovini. U Hrvatskoj se prodaju kvalitetni pripravci tako da ne trebate brinuti oko toga od kojeg proizvođača kupiti čaj.
