Many symptoms attributed to aging are also consistent with chronic inflammatory stress and impaired NAD metabolism. Dr. Charles Brenner explains the mechanisms, the human data, and what interventions actually move the needle. He also cuts through the crowded world of NAD boosters, including oral NAD pills, NMN, NR, and NAD IV drips, clarifying what actually raises NAD in humans and what emerging research suggests about NR for lowering inflammation and improving recovery.

One minute of vigorous exercise may be worth up to ten minutes of "moderate" cardio for extending lifespan and preventing chronic disease. In this Journal Club episode, Rhonda Patrick, PhD and endurance athlete Brady Holmer dissect a new Nature Communications study of more than 70,000 adults showing that vigorous intensity is roughly 4–10x more potent than moderate activity for reducing all-cause mortality, cardiovascular events, type 2 diabetes, and cancer outcomes—far beyond the long-standing 1:2 rule embedded in global exercise guidelines.

For decades, exercise was considered an optional part of cancer care—something beneficial for general health but not essential. The evidence is now overwhelming: exercise is not just supportive—it's a therapeutic intervention that recalibrates tumor biology, enhances treatment tolerance, and improves survival outcomes.
With over 600 peer-reviewed studies, Dr. Kerry Courneya's work has fundamentally reshaped our understanding of how structured exercise—whether aerobic, resistance training, or high-intensity intervals—can mitigate treatment side effects, enhance immune function, and directly influence cancer progression.

#006 Jim Kean Talks Biomarkers, Building a Spectator Sport
jeudi 2 juillet 2015 • Durée 32:51
Jim Kean
Jim Kean is the CEO of National Pro Grid League (NPGL) and founder of WellnessFX.
In this podcast Rhonda and Jim discuss the quantified self movement and the importance of measuring biomarkers more than once, the gut's role in cholesterol and serotonin in the gut versus in the brain, about the role of exercise in preventing neuroinflammation and the effects of overtraining on sex hormones.
We also chat a bit about the psychology of constructing a new, non-gender segregated, team spectator sport and bringing it to market, the factors that separate a professional spectator sport from any other form of entertainment: including patriotism, justice, and vicariousness, the mathematical nature of the sport and the floor coach's role in monitoring athletes before they start "redlining," how NPGL teams may find new ways to tune their gameplay and find an edge on the competition in the future by stepping up the use of more advanced athlete-level analytics.
In this episode, we discuss...
(00:00) Introduction
(01:11) Optimizing performance and health has become more accessible
(07:18) Frequent blood tests helped Jim find his optimal level of Vitamin D
(09:45) Jim's habits for optimizing insulin sensitivity and lean body mass
(11:06) Exercise reduces inflammation caused by kynurenine
(12:16) Exercise increases BCAA uptake by muscle, increasing serotonin in the brain
(13:33) Jim Kean introduces the book, Grain Brain
(14:32) Dysfunctional insulin receptors are found in Alzheimer's disease
(16:11) Endotoxin reacts with LDL cholesterol to form heart disease-promoting foam cells
(19:09) How you make a successful sport
(29:13) What is overtraining in cross-fit and what are the consequences?
Dr. Rhonda Patrick speaks with Dr. Bruce Ames, about a micronutrient- and fiber-dense nutrition bar (referred to as the CHORI bar) that was developed in the Ames laboratory.
The bar was formulated to be moderate in calories (107 kcal/≈25 g bar), but nutrient dense, with a polyphenolic-rich matrix of fruit, walnuts, and non-alkali-processed dark chocolate, supplemental vitamins, minerals, docosahexaenoic acid (DHA), a blend of insoluble and soluble fibers, protein, and glutamine. Most vitamins and minerals are present in amounts representing 10 to 50% of their corresponding recommended daily allowance (RDA) per bar; with the exceptions of vitamin D and vitamin C (both added above 50% RDA). The goal was not to meet the RDA in every case but to complement standard dietary intakes by consumption of 2 bars each day. People that ate the bar were told not to change their diets but just to eat the bars on top of their normal diet. Lean people that ate the CHORI bar twice a day were able to raise HDL, lower homocysteine, and raise glutathione in just two weeks. Overweight/obese people with low inflammation that ate the bar showed weight loss after 8 weeks, raised their HDL, lowered triglycerides and small LDL particles, and improved insulin sensitivity. Overweight/obese people that had high inflammation were able to lower their inflammation after 2 weeks of eating the bar and raise their HDL after 8 weeks.
