Below are some specific YouTube videos of interest about nutrition and health. (See also: Websites and YouTube channels of interest.)
Nutrition:

• Big Fat Nutrition Policy | Nina Teicholz - Ms. Teicholz will tell of her discovery of the systematic distortion of dietary advice by expert scientists, government and big business to the detriment of the health of Americans. She will chronicle the succession of unfortunate discoveries she made, and she will describe how the Nutrition Coalition, a non-profit, bipartisan group which she founded and directs, works to educate policy makers about the need for reform of nutrition policy so that it is evidence-based.
• Dr. Chris Knobbe - 'Diseases of Civilization: Are Seed Oil Excesses the Unifying Mechanism?' - Dr. Knobbe has a deep interest in general nutrition, particularly as it relates to chronic degenerative disease, though his primary area of expertise is with the disorder AMD. AMD is the leading cause of irreversible vision loss and blindness in people over the age of 65, currently affecting approximately 196 million people worldwide.​
• Dr. Paul Mason - 'Are you smarter than a Doctor? What your doctor doesn't know about nutrition' - Dr Mason developed an interest in low carbohydrate diets in 2011. Since then he has spent hundreds of hours reading and analysing the scientific literature. For a number of years, Dr. Mason has been applying this knowledge in treating metabolic and arthritis patients who have achieved dramatic and sustained weight loss and reductions in joint pain. Dr. Mason has recently become the Chief Medical Officer of Defeat Diabetes.
• Insulin resistance and why we get sick with Prof. Ben Bikman — Diet Doctor Podcast - In his new book, Why We Get Sick, Dr. Bikman makes a case for why we need to target insulin levels to improve global health. As you’ll hear him say, lifestyle choices can cause insulin resistance, and they can cure it, too. The tools are at our disposal; we just need to know what they are and how to use them.​
• The Mind-Blowing Science of Fat-Burning and Insulin Resistance with Dr. Benjamin Bikman - Host Dhru talks to Dr. Benjamin Bikman, a renowned metabolic research scientist, and a popular speaker on human metabolism and nutrition. Backed by years of research, Dr. Bikman’s mission is to help the world appreciate the prevalence and relevance of insulin resistance. He is the author of the newly released book, Why We Get Sick, which offers a thought-provoking yet real solution to insulin resistance and how to reverse pre-diabetes, improve brain function, shed fat, and prevent diabetes.
• Optimal Diet for Humans - Stomach Acid | Dr Nadir Ali - Dr. Nadir Ali is a practicing Interventional Cardiologist in the Clear Lake and Bay Area community for 30+ years. He has a several years of experience in the Low Carbohydrate High Fat (LCHF) diet in the treatment of metabolic disease, diabetes, heart disease and to improve the quality of cholesterol.

​Living and fitness:

• Dr. Rhonda Patrick: Hormetic Stressors - Health Benefits of Sauna and Cold Exposure - Dr. Patrick trained as a postdoctoral fellow at Children’s Hospital Oakland Research Institute with Dr. Bruce Ames, where she investigated the effects of micronutrient (vitamins and minerals) inadequacies on metabolism, inflammation, DNA damage, and aging and whether supplementation can reverse the damage. In addition, she also investigated the role of vitamin D in brain function, behavior, and other physiological functions. Dr. Patrick has also done research on aging at the Salk Institute for Biological Sciences.
• The Older Muscle: Aging or Disuse? - Prof. [Stephen] Harridge - The prime role of muscle is to act as a biological machine - to produce force and generate power. This is to fulfil a number of different functions from maintaining posture to allowing the performance of all the physical tasks needed for everyday living. But, muscle also has a plethora of other roles which include protein being an important dynamic store, being the largest sink for the storage of glucose and acting as a source of protective padding. As we get older there is an observable reduction in many of these functions.
• Protein, Muscle and Inactivity: Projecting Muscle Health During Aging by Douglas Paddon-Jones, PhD - Douglas Paddon-Jones, PhD, FACSM, is a Professor in the Department of Nutrition & Metabolism in the School of Health Professions (SHP) at the University of Texas Medical Branch (UTMB). Dr. Paddon-Jones is also the Sheridan Lorenz Distinguished Professor in Aging and Health, a fellow of the American College of Sports Medicine, and a senior fellow of the Sealy Center on Aging.
