Adding milk to tea can blocks its beneficial effects, potentially explaining why green tea drinkers appear better protected than consumers of black tea.

Sham surgery trials prove that procedures like nonemergency stents offer no benefit—only risk—to millions of patients.
Subscribe to NutritionFacts.org’s free newsletter to receive our B12 infographic that covers the latest research takeaways and Dr. Greger’s updated recommendations: https://nutritionfacts.org/subscribe/
At this point, you may be thinking what a shameful, dark period of medical history. Millions of risky procedures were performed, killing people and causing strokes before it was actually put to the test. When it finally was, it was proven to offer to no benefit. Certainly, a cautionary tale for the future. In fact, they’re still being done. It's still one of the most common invasive procedures performed in the United States. Why Are Stents Still Used if They Don’t Work? That’s the subject of the next video.
This is part of a seven-video series. If you need to catch up, here are the first four:
• Do Angioplasty Heart Stent Procedures Work? (http://nutritionfacts.org/video/do-angioplasty-heart-stent-procedures-work)
• Why Angioplasty Heart Stents Don’t Work Better (http://nutritionfacts.org/video/why-angioplasty-heart-stents-dont-work-better)
• The Risks of Heart Stents (http://nutritionfacts.org/video/the-risks-of-heart-stents)
• Angioplasty Heart Stent Risks vs. Benefits (http://nutritionfacts.org/video/angioplasty-heart-stent-risks-vs-benefits)
As I say over and over in this video series, during a heart attack, in an acute setting, angioplasty can be life-saving. As I reiterate, when I’m talking about stable CAD, I’m talking nonemergency situations. In an upcoming series I talk about pros and cons of statin drug therapy. Spoiler: If you have a history of heart disease or stroke, taking a statin is recommended. All of these videos, including the upcoming statin series, are available on a digital download of a webinar I did last year. You can find it here: https://drgreger.org/collections/videos/products/how-effective-are-statins-and-stents-digital
UPDATE: A new meta-analysis was just published last month and alas, there is still zero survival benefit to stent placement for stable coronary artery disease, but at least there were fewer heart attacks. Since this still didn’t translate into actually living any longer, the foundation of treatment remains medical and lifestyle management. Hat tip to Dr. Bitterman! (https://pubmed.ncbi.nlm.nih.gov/33742721/)

Is the sodium debate a legitimate scientific disagreement or a “controversy” manufactured by industry?
Subscribe to NutritionFacts.org's free e-newsletter and receive a recipe from Dr. Greger's brand-new cookbook, The How Not to Diet Cookbook: https://nutritionfacts.org/subscribe/
This is my second video in my new in-depth series on the sodium “controversy.” See the first one at High Blood Pressure May Be a Choice (http://nutritionfacts.org/video/high-blood-pressure-may-be-a-choice/).
More on hypertension in How to Prevent High Blood Pressure with Diet (http://nutritionfacts.org/video/how-to-prevent-high-blood-pressure-with-diet/) and How to Treat High Blood Pressure with Diet (http://nutritionfacts.org/video/how-to-treat-high-blood-pressure-with-diet/). What if you already eat healthy and still can’t get your pressures down? Try adding hibiscus tea (Hibiscus Tea vs. Plant-Based Diets for Hypertension http://nutritionfacts.org/video/hibiscus-tea-vs-plant-based-diets-for-hypertension/) and ground flax seeds (Flax Seeds for Hypertension http://nutritionfacts.org/video/flax-seeds-for-hypertension/) to your diet. And make sure you’re exercising regularly (Longer Life Within Walking Distance http://nutritionfacts.org/video/longer-life-within-walking-distance/).
But if you cut down on salt won’t everything taste like cardboard? Your taste buds shift remarkably quick: Changing Our Taste Buds (http://nutritionfacts.org/video/changing-our-taste-buds/).
If you’re surprised about industry tactics to distort the balance of evidence, here’s a few other poignant examples:
• The McGovern Report (http://nutritionfacts.org/video/the-mcgovern-report/)
• Big Sugar Takes on the World Health Organization (http://nutritionfacts.org/video/big-sugar-takes-on-the-world-health-organization/)
• Who Determines if Food Additives are Safe? (http://nutritionfacts.org/video/who-determines-if-food-additives-are-safe/)
• Who Says Eggs Aren’t Healthy or Safe? (http://nutritionfacts.org/video/who-says-eggs-arent-healthy-or-safe/)
• Collaboration with the New Vectors of Disease (http://nutritionfacts.org/video/collaboration-with-the-new-vectors-of-disease/)
• Food Industry Funded Research Bias (http://nutritionfacts.org/video/food-industry-funded-research-bias/)
Lots more salt videos to come!

DESCRIPTION: Though prebiotics may be preferable, probiotics may reduce the risk of upper respiratory tract infections.
Probiotics do play an established role in helping to prevent antibiotic-associated diarrhea and may speed recovery from acute gastroenteritis. See my last video, Preventing and Treating Diarrhea with Probiotics (http://nutritionfacts.org/video/preventing-and-treating-diarrhea-with-probiotics/). When should they be taken? That's the subject of my next video, Should Probiotics Be Taken Before, During, or After Meals? (http://nutritionfacts.org/video/should-probiotics-be-taken-before-during-or-after-meals/).
How else might we reduce our risk of getting an upper respiratory infection? See:
• Can Gargling Prevent The Common Cold? (http://nutritionfacts.org/video/can-gargling-prevent-the-common-cold/)
• Are Cats or Dogs More Protective For Children's Health? (http://nutritionfacts.org/video/are-cats-or-dogs-more-protective-for-childrens-health/)
• Sleep & Immunity (http://nutritionfacts.org/video/sleep-immunity/)
• The Risks and Benefits of Neti Pot Nasal Irrigation (http://nutritionfacts.org/video/the-risks-and-benefits-of-neti-pot-nasal-irrigation/)
You can tach a video of white blood cells chomping actually down on foreign invaders in my video Clinical Studies on Acai Berries (http://nutritionfacts.org/video/clinical-studies-on-acai-berries/). A must-see for biology geeks!
The immune boosting fruit and vegetable video I reference is Boosting Immunity Through Diet (http://nutritionfacts.org/video/boosting-immunity-through-diet/). See also Kale and the Immune System (http://nutritionfacts.org/video/kale-and-the-immune-system/) and last week's video Boosting Immunity While Reducing Inflammation (http://nutritionfacts.org/video/boosting-immunity-while-reducing-inflammation/).

DESCRIPTION: Cardiology experts warn that eating even a single egg a day may exceed the safe upper limit for cholesterol intake. Have a question about this video? Leave it in the comment section at http://nutritionfacts.org/videos/egg-cholesterol-in-the-diet/ and I'll try to answer it! Check out my blog post "Bad Egg" (http://nutritionfacts.org/blog/2011/08/31/bad-egg/) to help put egg consumption in context, and don't miss
Avoiding cholesterol is a no brainer (http://nutritionfacts.org/video/avoiding-cholesterol-is-a-no-brainer/) and Egg industry blind spot (http://nutritionfacts.org/video/egg-industry-blind-spot/) for more misleading claims from the egg industry.

Does calcium citrate and calcium carbonate have as much lead as calcium supplements derived from dolomite and animal bone?

Wow, wasn’t that an amazing story? And just so incredibly sad.

Even if supplements had no contamination, check out my videos Are Calcium Supplements Safe? (https://nutritionfacts.org/video/are-calcium-supplements-safe) and Are Calcium Supplements Effective? (https://nutritionfacts.org/video/are-calcium-supplements-effective).
