Dr. Greger Takes on Smoothies in New DVD

Volume 26 launch

Smoothies have been one of the most requested topics, but for years there seemed to be little pertinent research. I was surprised when I reprised my search this year to find hundreds of studies, so it’s smoothie-time! I rarely do such long contiguous video series any more, but I had neglected the topic for so long I wanted to get them out. I review the latest science in five new videos:

  • Are Green Smoothies Good for You?
  • Are Green Smoothies Bad for You?
  • Green Smoothies: What Does the Science Say?
  • Liquid Calories: Do Smoothies Lead to Weight Gain?
  • The Downside of Green Smoothies

They are available right now as a video download as part of my new Latest in Clinical Nutrition volume 26 (all proceeds go to this charity). The smoothie videos are all scheduled to go up on NutritionFacts.org in September, but you can download and watch them right now.

Wait a second. Why spend five videos sifting through the science, profiling all the original experiments, and turning it into one big detective story when I could have just cut to the chase and did a five second video and basically said “Drink them” or “Don’t drink them”? Because I don’t want you to ever do anything just because I or anyone else “said so.” That’s one of the problems with the field of nutrition. Everyone seems to have their respective gurus who too often make pronouncements without explaining their reasoning and citing their sources. Can you imagine that flying in any other field of science? It’s not what he said or she said; it’s that the best available balance of evidence bears out. Two plus two equals four no matter what your favorite mathematician says.

The current batch of videos from volume 25 on NutritionFacts.org just ran out, so starting now and running until October, I’ll be rolling out the videos from this new DVD, volume 26. The DVDs give folks the opportunity to sneak-preview videos months ahead of time, watch them all straight through, and share them as gifts, but there is nothing on the DVDs that won’t eventually end up free online at NutritionFacts.org. If you’d like the works–40+ hours of video–you can get the complete DVD collection.
Here’s the list of chapters from the new volume 26 DVD — a preview of what’s to come over the next few months on NutritionFacts.org:

The Nutritional Yeast Research Results Are In

Thanks to everyone who donated to the NutritionFacts.org Research Fund, we were able to test eight brands of nutritional yeast for the presence of the toxic heavy metal lead. The good news is that we couldn’t find any in most brands, but a few did have detectable levels. The lead contamination was so low that all brands complied with the exceedingly (and justifiably) strict California Prop 65 standards, but I do I advise pregnant women who eat more than a third of a cup a day on a regular basis choose one of the brands that tested free from detectable lead until we know more. Joseph includes details and direct links to all the testing reports in this morning’s blog post Three Brands of Nutritional Yeast Contain Detectable Lead Levels But the Risk is Minimal. What should we test next? Please post your suggestions to the Research Fund page.

If you would like to participate in a research study yourself, you’re in luck! Scientists at Tufts University are currently recruiting adults ages 18+ for an important study on diet and disease. Take the recruitment survey here: http://bit.ly/tuftsresearch

If you’d like to attend a scientific conference and directly learn about cutting-edge nutrition research, I’m speaking at a few in the coming months and would love to see you there:

Keep hydrated out there!
