Latest in Clinical Nutrition: Volume 10
The “volumes” refer to a series of DVDs (now digital only) upon which NutritionFacts.org is based (all proceeds donated to charity). The DVDs give folks the opportunity to sneak preview videos months ahead of time, watch them all straight through, and share as gifts, but there’s nothing on the DVDs that won’t eventually end up online free at NutritionFacts.org.
Volume 10 is the fifth NutritionFacts.org DVD covering the peer-reviewed scientific nutrition literature published between spring 2011 and summer 2012. For more information about Volume 10 click here.
