Related Episodes for Sulforaphane and isothiocyanate goitrogen concerns | Rhonda Patrick

“Dr. Patrick also revises an earlier concern about acrylamide: although roasting can form it, the human evidence she reviews does not show that ordinary coffee intake raises cancer risk, and the overall epidemiology points in the opposite direction for several cancers.”

“00:20:21 - Some of the key blood-based biomarkers that are useful for tracking and projecting future cognitive health, including: homocysteine (<7μml/L preferred), which Dr. Bredesen indicates may be a mediator of cerebral atrophy, and also fasting insulin (<5% preferred), hemoglobin A1c, fasting glucose, vitamin D, and a number of other hormones relevant for trophic support.”

“A smaller comparative study found improved hair density, shaft size, and anagen-follicle proportion with 2 percent ketoconazole shampoo, while its authors called for larger controlled studies. These results support individualized combinations rather than one universal protocol.”

“Emerging evidence suggests that IGF-1 also regulates the aging process via its influence on growth hormone. In this clip, Dr. Valter Longo describes the IGF-1 pathway and explains how defects in the pathway influence disease risk.”

“Translating sleep insights into practical steps These findings highlight the possibility of using heat therapy or vigorous exercise to influence slow-wave sleep, drawing on the interplay between body temperature regulation, immunity, physical activity, and hormones.”

“Exercise response can vary between sexes, with elements like menstrual cycles adding another layer of complexity. While research gaps exist, for example, concerning elevated cortisol levels during exercise, such levels don't appear to chronically elevate to harmful extents.”

“One laboratory study found that disposable paper cups exposed to 85 to 90°C water released about 25,000 micron-sized particles into 100 milliliters within 15 minutes, along with many smaller particles. Tea bags can provide another source of exposure.”

“In a small study of 10 men, twice-weekly sauna sessions for three months altered sperm production and function, with recovery documented during follow-up after sauna use stopped. Sperm outcomes and circulating testosterone are distinct measures of reproductive function.”

“Whereas fasting turns off multiple pathways associated with aging, such as mTOR and IGF-1, eating for optimal fitness activates these important processes. The IGF-1 pathway, in particular, plays key roles in growth and is strongly associated with cancer.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”
