“The main ingredient-interaction evidence concerns polyphenol oxidase. A small controlled crossover study found that a high-PPO banana smoothie greatly reduced circulating flavan-3-ol metabolites compared with a low-PPO berry drink or capsule control.”
Episode
“In the past, humans' primary exposure to blue light was from the sun, but in modern times, electronic devices – TVs, computer screens, and cell phones – expose us to increasing amounts of blue light, often during times of the day or night that are out of sync with our bodies' natural rhythms.”
Clip
“In a short controlled protocol in healthy young men, five nights of restricted sleep impaired glucose tolerance and muscle mitochondrial function, while participants who added high-intensity interval exercise did not show the same changes.”
Clip
“Easy or moderate movement may be appropriate after a mildly short night, while severe sleepiness is a reason to reduce training demands and prioritize rest. This clip is excerpted, with permission, from Dr. Rhonda Patrick's appearance on Huberman Lab.”
Episode
“In a previous episode, entitled "Maximizing Your Mitochondria with Magnesium," we learned that 45% of the US population is deficient in magnesium and the important role magnesium plays in mitochondrial function and how this relates to exercise performance by ensuring your muscle cells have the highest oxidative capacity (ability to produce ATP or "energy") possible.”
Clip
“Metformin, a drug commonly used to treat type 2 diabetes, has garnered interest as a longevity compound because it was shown to extend lifespan in some animal models. These effects are variable and seem to depend on the age and gender of the animals, as well as the dose provided.”
Clip
“The fact that poor sleep is linked with the aggregation of amyloid-beta plaques in the brain and Alzheimer's disease is not surprising. Although some strategies for improving the quality of sleep among people with Alzheimer's have been identified, this might be too late to turn the tide of cognitive decline.”
Episode
“Removing former drinkers from the non-drinker category reveals a different story: One study observed that the lowest risk for cardiovascular disease (i.e., ischemic heart disease) was right below one standard U.S. drink per week — men and women at this level of consumption had an ~18% lower risk compared to nondrinkers.”
Clip
“Dr. Huberman’s practical range is deliberately cautious: not drinking avoids the exposure, and lower weekly intake creates less burden than a drink every night or heavier episodes.”
