Funzione del tè e delle arterie

L'aggiunta di latte al tè può bloccarne gli effetti benefici, spiegando potenzialmente perché i bevitori di tè verde sembrano più protetti rispetto ai consumatori di tè nero.

Se è quello che può fare una pianta, immagina gli effetti di un'intera dieta incentrata sui cibi vegetali. Questo è l'argomento del mio prossimo video, Diete a base vegetale e funzione dell'arteria (http://nutritionfacts.org/video/plant-based-diets-and-artery-function).

  1. I'm Dutch and lots of people here actually have milk in their tea. I like black or green tea with sugar so I guess I'll be fine 🙂

  2. Side note: If you're Vegan and drinking teacoffee look into your diet because chances are you are not eating enough or getting enough sugar and to compensate you want caffeine.

  3. Wow! Just a tiny splash of milk is that deleterious to our health? Here's another "maybe" for ya, maybe the brits have a decline in endothelial function because they eat too much fatty meat, like bangers…

  4. Noooooooo! About to have my daily big mug of builder's tea with soy milk! I guess it's my last one; back to black tea tomorrow. : ( Thanks for posting!

  5. But does one who lives a hclf vegan lifestyle need to consume the likes of green tea to have the same affects? I would imagine that this isn't needed with a hclf vegan diet.

  6. So if soy protein does the same as casein… does that mean we shouldn't drink soy milk in our tea?
    I make my own nut/oat milks, but, while they are great for oats, cereal and other cold things, they don't taste that great in hot beverages, so I usually go for store-bought organic soy milk for my tea.

  7. Dr Greger the Netherlands is NOT the Only Country…. I pretty sure England is the only country that puts milk in tea….No body I know in my countries Austria and Czech Republic drinks tea with Milk in it…the Swiss and Germans don't do it either, Italians don't do it Russians don't do it,…,…..since I have been in the USA I have never seen anybody put milk in it either….I myself would never even consider to but milk in my Tea… I love Black Tea with lemon and some raw cane sugar, and Green Tea with just raw cane sugar….so delicious!

  8. Is it due to the relatively high methionine content of both soy and cow's milk ? Something else ?
    It raises many questions, this is fairly interesting !

  9. Go Netherlands! Honestly the only reason I see why English people drink their tea with milk is because they make their tea soo flipping strong and bitter that it is super gross (and I asume that this is less so when they add Milk). In the Netherlands most people also don't like bitter tea, but instead of adding Milk, we take out the tea bag faster and we have lots of diffrent flavours of tea.

  10. Dr. Greger, I know from many of your videos that drinking tea is good but what about the steeping process? If a tea is steeped for longer is it better than the same tea not steeped as long?

  11. Most Australians take milk in their black tea also. I don't take milk because I'm lactose intolerant and I got used to the taste so I like it that way. People think I'm a bit strange. 🙂 I also drink a lot of green tea.

  12. Well this is just perfect. I came over to this channel to find one of his videos on tea and low and behold, a new one appears. Anyway, if you are going to drink green tea not only should you drink it straight up but you should also get the loose leaf version as well. Since they have more surface area, they will release more polyphenols into the water and generally taste better. Most tea bag tea goes stale when its sitting on the shelf in the store.

  13. I make matcha with soymilk sometimes, do you think that'd hurt the good effects? I also drink Earl Grey with soymilk on occasion too.

  14. Could you do a video on IMOs, like they are found in vitafibre?
    So, if I used pure VitaFibre (Isomalto-Oligosaccharides), not by taking QuestBars (I know there is a lot of junk in there), but by using the syrup in baking, would it be healthy?
    Thank you, it is much appreciated!

  15. Dr. Greger, please make a video on the effect of Green Smoothies on the Endothelial Cells. I'd like to clear that up once and for all.

  16. what about the effects of adding Soy Creamer on coffee???? Does in blunt any nutritional benefit in the coffee? Dr. Greger, please make a video on this. 😉

  17. It is all well and good that orientals eating healthy ALL their lives retain good endothelial function into old age. But what about oldster USians who have been damaging their guts with decades of SAD. Do THEIR replacement endothelial cells reacquire youthful function? The video…doesn't say.

  18. This is such fucking bullshit, drinking tea does not effect artery function and milk doesn't do shit for heart disease or else I would of been dead at age 11.

  19. Dr.Greger,

    Thank you for showing your references in the video. Providing references from bone fide scientific peer reviewed journals helps people see where the data came from and assures a greater level of confidence. It also helps thwart the glut of pseudoscience claims made by less conscientious people and non-scientists.

    I would like to suggest you also provide links in the description section so your interested viewers can read those papers for themselves.

    regards,
    LL

  20. I imagine this is not the case with coconut milk. I make a concoction of green tea, herbal teas, turmeric, ginger, and other herbs, along with raw honey, coconut milk, and the juice from a fresh lemon wedge.

  21. What about other teas such as rooibos? Does drinking it with alternative milk such as out or almond milk lessen the effect from the antioxidants?

  22. Russians and all other people of around 140 different nationalities who lived in the ex-USSR never drank tea with milk unless they took this stupid habit after watching too much TV about brits. Even after spending 12 years of my life in boring Ireland with boring Irish husband drinking their boring extremely tasteless so called tea i couldnt get it – what for to spoil the normal drink pouring chemicals loaded shity milk from sick hormonal cows ?This liquid even has no right to be called milk in the first place.So this habit is mostly anglo-saxons national past- time

  23. As a Brit; ar5e!!!! soya milk ruins the effects of tea, arhhhhhhh nooooooo it took 5years to get used to soya milk! i have to drink tea black, bugger…might have to put a trigger warning on this for Brits and the Irish… really my question is is there anything you can put in that does not effect the tea?? black tea smell makes me queasy, green tea fine, even put soya milk in that, and other herbal teas, it's a habit, oh and some made for me in pokhara nepal, when my supply of soya milk powder ran out, very eathy holemealy, very strong! well ive been vegan 25years im allowed my eccentricities.

  24. I'm from the Netherlands and I was thinking "but we drink it without milk" and then you said it. I'm glad black tea is about as good as green tea, because even though I've been drinking green tea for a couple of decades for health, I always still prefer black tea for flavor.

  25. Can I assume Hibiscus tea does this even more effectively? I took your advice and have been sipping four bags of hibiscus tea in two litres of water with a cup of lemon juice and clove powder, love it! Cept it has given me hey fever something shocking, haven't sneezed so much in 24 hrs ever. Also lowered my blood pressure noticeably, which would have been great if it was high, it was perfect, and made me feel quite giddy as a result. I thought I might check if there were any side effects to hibiscus tea, and sure enough the hey fever and lowering of blood pressure were two of a few side effects. So now I'm not sure what to do, drink less? don't use four bags?

  26. n=17. Can we really make inferences for billions of people based on the results of only 17 people studied in short term and under artificial conditions?

    Furthermore, Netherlands has a high proportion of milk drinkers. Therefore, milk may blunt the beneficial effects of tea but the long term cardiovascular effects have not been demonstrated by this study.

  27. It could be the milk, but black tea is typically more oxidized that green tea: they are differentiated primarily by how they are cultivated. This oxidation, i would wager, might be the difference not only in antioxidant content, but ability to prevent oxidation in the bloodstream.

  28. Confused. The literature I can find on side effects of caffeine states that caffeine is a vasoconstrictor which narrows veins and arteries. In my case at age 65 when I drink tea my ankles swell just like they would if I eat salt which I quit doing. I found a forum where numerous people claimed the same problem. I have been on a whole food vegan diet for years that would make Esselstyn smile. I am 6 ft tall and only weigh 135 lbs and am active and live a lifestyle modeled after the Okinawan centenarians. If tea should improve circulation why am I getting symptoms of vascular insufficiency in my legs? I even developed hemosiderine staining in the lower legs after about a year of adding green and white tea to my diet, and I only use it on average 50 percent of the time and only 2 or 3 grams of loose tea in a day…maybe 4 occasionally which is equivalent of 2 tea bags. If I stop the tea, the edema abates. I am now a tea addict after seeing all the benefits and don't want to give it up, but this information on blood flow and green tea makes me really wonder????

  29. Dr Greger and team, I would like to thank you for all the amazing work you do. It's so refreshing in these days to see information always backed up with good science. We need some way to get your message across to a larger proportion of the world population. People are confused because they are constantly bombarded with news supporting unfounded beliefs. Thank you again.

  30. Does the soy proteins from dietary soy neutralize the benefits of drinking tea? Did they check that with the Chinese population studied?

  31. I drink my matcha with coconut or almond milk. In just water it kinda makes me wretch. Any idea if those milks will also nullify the positive effects of green tea?
