The Official Livin' La Vida Low-Carb Forum

I've heard about green tea helping weight loss, but not sure I every read the suggested amount before the current article in Woman's World. I know they aren't the best diet resource, but the article did have some interesting information. Says a Penn State study showed that green tea interferes with an enzyme that allows our bodies to get calories out of fat. Suggested amount of green tea is 6-8 cups a day or 48-64oz. Mentions that the drug Alli works by targeting the same enzyme. It also mentions that green tea seems to make blood sugars go down and boost metabolism by about 6%. 6-8 glasses is more than I've ever drank a day, but I'm going to give it a try this week.

There are lot of links below this article on benefits of green tea. http://www.nutraingredients.com/Research...-low-doses
Yes, I've heard great things about the benefits of green tea! Awesome...
I think we have to be careful to understand what is meant by GREEN TEA.

I have been using GREEN TEA as my main beverage for some years now.
I use LEAF TEA.

That means TEA LEAVES and a TEA POT and an understanding of how to make a pot of tea.

Although the Green Tea leaves are more expensive you can REUSE them through the day.
So the pot I have in bed first thing will be re-brewed after breakfast, mid-morning and maybe also after lunch.
It really is important NOT to overheat the water and NOT to let it brew too long.

While tea bags are OK for emergency use and when away from home they are not as good a grade tea as the leaf forms and a lot better than "Green Tea" drinks that are sometimes available in supermarket in the UK. I think these must be made from the very worst grade leaves or have sugar/sweeteners or other processing done. So beware ready made tea and anything that you don't brew yourself from proper Green Tea Leaves.

Green tea is an anti inflammatory agent so encourages those LEAN typeE gut flora to proliferate and discourage the pro inflammatory OBESE type gut flora from proliferating. Green tea is also antibiotic and anti fungal and increases energy expenditure, (making you more active = burn more calories)and it stimulates thermogenesis (upregulates body temperature = burn more calories)

Do bear in mind it is an acquired taste. You may need to start with VERY weak green tea very short brews initially and gradually work up to several cups a day. Apart from coffee (and perhaps redwine & whisky) I don't drink anything else. I make my tea with magnesium rich water because I want to increase my magnesium intake. I don't think that affects the taste but it may enhance the anti inflammatory action.

I should perhaps add that I had converted to Green Tea BEFORE I converted to Low Carb and so while I was still eating bread/cereals/grains/carbs it didn't make much difference. However now I'm low carbing and have addressed other pro inflammatory factors, green tea does add to those anti inflammatory antimicrobial factors and works in synergy with them.
Thanks for the information. I am using the green tea bags, but have a near by co op that should have the leaves. I enjoy the taste of green tea. Good to know about the anti inflammatory benefits too.
I am planing to try l-theanine , a green tea extract which calms down and relaxes but it's not for weight loss.

I brew a mason jar full of strong green tea every morning and drink it cold in the afternoon. It hasn't made me thin, but I enjoy it.
Green Teas and Black Teas may be the healthiest drinks available. It may make you live longer, but it won't make you lose weight unless . . . drinking tea, whether it is hot or iced, instead of sugary soft drinks or juice will cause you to lose weight.
Of course you are right that replacing caloric beverages with non caloric beverages reduces calorie intake and will help but the anti inflammatory action of green tea affects the type of gut flora and they determine the amount of calories absorbed from the food you consume.
Those gut flora that prefer higher inflammatory environments are more effective calorie producers, those that thrive best in a low inflammatory environment absorb fewer calories so drinking green tea is anti inflammatory and will, IN IT'S OWN RIGHT given the change in gut flora tea consumption creates, lead to lower calorie uptake.

Similarly green tea is an iron chelator Iron behaving badly causes dysfunctional mitochondria. Thermogenesis is controlled by Brown Adipose Tissue and dysfunctional mitochondria mean poorer thermogenesis It follows that drinking Green Tea improves Thermogenisis

This gives a reasonable idea of where I'm coming from.
main effects of the antiinflammatory dietary mix
Bear in mind they used GT capsules along with other anti inflammatory supplements You can copy their mix using more effective forms/amounts of vitamin D, vitamin C etc.
Protective Properties of Green Tea Uncovered
Quote:ScienceDaily (Jan. 6, 2011) — Regularly drinking green tea could protect the brain against developing Alzheimer's and other forms of dementia, according to latest research by scientists at Newcastle University.
The study, published in the academic journal Phytomedicine, also suggests this ancient Chinese remedy could play a vital role in protecting the body against cancer.
Led by Dr Ed Okello, the Newcastle team wanted to know if the protective properties of green tea -- which have previously been shown to be present in the undigested, freshly brewed form of the drink -- were still active once the tea had been digested.
Digestion is a vital process which provides our bodies with the nutrients we need to survive. But, says Dr Okello, it also means that just because the food we put into our mouths is generally accepted to contain health-boosting properties, we can't assume these compounds will ever be absorbed by the body.
"What was really exciting about this study was that we found when green tea is digested by enzymes in the gut, the resulting chemicals are actually more effective against key triggers of Alzheimer's development than the undigested form of the tea," explains Dr Okello, based in the School of Agriculture, Food and Rural Development at Newcastle University.
"In addition to this, we also found the digested compounds had anti-cancer properties, significantly slowing down the growth of the tumour cells which we were using in our experiments."
As part of the research, the Newcastle team worked in collaboration with Dr Gordon McDougall of the Plant Products and Food Quality Group at the Scottish Crop Research Institute in Dundee, who developed technology which simulates the human digestive system.
It is this which made it possible for the team to analyse the protective properties of the products of digestion.
Two compounds are known to play a significant role in the development of Alzheimer's disease -- hydrogen peroxide and a protein known as beta-amyloid.
Previous studies have shown that compounds known as polyphenols, present in black and green tea, possess neuroprotective properties, binding with the toxic compounds and protecting the brain cells.
When ingested, the polyphenols are broken down to produce a mix of compounds and it was these the Newcastle team tested in their latest research.
"It's one of the reasons why we have to be so careful when we make claims about the health benefits of various foods and supplements," explains Dr Okello.
"There are certain chemicals we know to be beneficial and we can identify foods which are rich in them but what happens during the digestion process is crucial to whether these foods are actually doing us any good."
Carrying out the experiments in the lab using a tumour cell model, they exposed the cells to varying concentrations of the different toxins and the digested green tea compounds.
Dr Okello explained: "The digested chemicals protected the cells, preventing the toxins from destroying the cells.
"We also saw them affecting the cancer cells, significantly slowing down their growth.
"Green tea has been used in Traditional Chinese medicine for centuries and what we have here provides the scientific evidence why it may be effective against some of the key diseases we face today."
The next step is to discover whether the beneficial compounds are produced during digestion after healthy human volunteers consume tea polyphenols. The team has already received funding from the Biotechnology and Biological Sciences Research Council (BBSRC) to take this forward.
Dr Okello adds: "There are obviously many factors which together have an influence on diseases such as cancer and dementia -- a good diet, plenty of exercise and a healthy lifestyle are all important."
Green tea has been one of my favorites for years, but I have always used tea bags. I do not have the cultural background of tea leaves and tea pots, but I would like to learn. I have been using STASH tea for the past year. It seems to be a good quality tea. What is the thinking on white tea? I drink one labelled as a fusion of white and green teas. I used to be able to find straight white tea and like it quite a bit. It has a milder flavor than green. Thanks.
Stash website has good information

Quote: I have been using STASH tea for the past year. It seems to be a good quality tea.
The website seems to be very detailed.


Quote:What is the thinking on white tea?
White and green teas (Camellia sinensis var. sinensis): variation in phenolic, methylxanthine, and antioxidant profiles. It doesn't look from this paper that paying more money for white tea buys you more benefits in the way of health giving properties. It's really a matter of taste and affordability. I use Gunpowder Temple of Heaven Green Tea as my basic daily brew and when our cheapo supermarkets Lidl or Aldi have green leaf tea on special offer I'll try those.

Quote:It has a milder flavor than green.
You can adjust the flavour of green tea by shortening the brewing time and reusing the leaves. I make a pot first thing in the morning and keep adding a mug of off the boil water through the day until it's too weak to enjoy. So although the leaves may seem expensive if your only using one teaspoon a day and making that last through the day it's not too bad. It's a lot cheaper than red wine and I'm sure better for me.
Thanks, Ted. I appreciate your help
I know I have a teapot around here somewhere. I let you know how it goes.

Green tea prevents non-melanoma skin cancer by enhancing DNA repair
Quote:UV-induced DNA damage, particularly the formation of cyclobutane pyrimidine dimers, has been implicated in immunosuppression and initiation of skin cancer. Topical application or oral administration of green tea through drinking water of mice prevents UVB-induced skin tumor development, and this prevention is mediated, at least in part, through rapid repair of DNA. The DNA repair by GTPs is mediated through the induction of interleukin (IL)-12 which has been shown to have DNA repair ability. The new mechanistic investigations support and explain the anti-photocarcinogenic activity, in particular anti-non-melanoma skin cancer, of green tea and explain the benefits of green tea for human health.
green tea and fluoride

and I don't think tea is related to weighloss especially since most people have it sweetened
http://www.google.ca/search?sourceid=nav...a+fluoride
and I don't think tea is related to weighloss especially since most people have it sweetened Surely NOT.
there are plenty of instructions for making green tea online.
The important points are that the water should be off the boil and the brewing time is limited to 2 minutes. That way the tea will not be bitter and there will be no need for sugar.

The shorter steeping time and using water off the boil reduce the fluoride (and caffiene content) of green tea.
Selenium counteracts the toxic effects of fluoride If you live in a low selenium area you could supplement with selenium. (it has other benefits apart from counterbalancing flouride)
In the UK only around 10% of water has fluoride added in the USA it's more like 60%.
The amount of fluoride in the tea is related to tea quality. This is why I use LEAF tea. That is usually the best with teabags lesser quality and the worst grade goes to commercial ready made tea.

I agree that sweetened tea would be counter productive. What matters in practice is what happens in real life and there is ample science showing the overal impact of green tea consumption is beneficial.
There is considerable evidence that tea polyphenols, in particular (-)-epigallocatechin-3-gallate (EGCG) inhibit carcinogenesis.

Green tea drinking is inversely associated with urinary incontinence. The reason for this is that the main cause of UTI is E Coli bacteria and and green tea inhibits E COLI if you drink enough of it.
The trouble with the research on substances such as green tea as a weight loss aid is that the reports only include information about the statistical mean results and not the outliers. For whom does the green tea not work? For whom does it work best? Doesn't do anything for me.
I agree that it is the context that matters. If all your car tyres are totally deflated putting a little bit of air in one of them isn't going to make a lot of difference.
Similarly if you just inflate one tyre to the correct pressure (ie correct just one anti inflammatory deficiency state) again in the context of having all the other tyres deflated, correcting one tyres air deficiency state isn't going to achieve much.

I think we've got to put anti inflammatory anti oxidant agents into the context of the major pro inflammatory pro oxidation forces, REFINED CARBOHYDRATES, OMEGA 6 INDUSTRIAL SEED/GRAIN OILS are the major drivers, Magnesium deficiency and low omega 3 intakes follow, then we have to consider vitamin D deficiency, Low melatonin secretion from not having a good circadian rhythm, and high cortisol levels from the stress of modern urban living, particularly so for poor people.

Drinking green tea, or having a couple of square of dark chocolate will only make a difference if you've attended to everything else that is driving inflammation/oxidation in your life/environment and diet.

But if you reduce the level of pathogenic bacteria in your digestive system and replace them with anti-inflammatory pro-bifidogenic gut flora this can only help.

But like many communities, your gut flora dislike invaders sol try to prevent new immigrants taking over the community.
Ted Talks Bonnie Bassler on Bacteria quorum sensing

This is why when using Green Tea or other strategy to reduce pathogenic bacteria you have to be persistent over a long time frame and while attacking the pro inflammatory types keep providing a supply of new biffidobactia (live yoghurt) and the Fructooligosaccharides (onions, leeks jerusalem artichokes etc) they thrive on.
