“Moreover, taking mega doses (i.e. 400 IU/day) of alpha tocopherol has the unintended side-effect of actually depleting tissue levels of another important form of vitamin E that plays an anti-inflammatory role, known as gamma tocopherol.”

“Her practical message is to reduce the frequency and size of large glucose exposures. Foods with intact fiber, protein, and minimally processed carbohydrates digest more slowly than refined added sugar, while regular exercise gives skeletal muscle a large destination for circulating glucose.”

“Sure, those dates on the calendar pass at the same rate for everybody, but some people appear to age slower (or faster) than others – with vastly different age-related physical changes and disease risks.”

“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.”

“Patients assigned to supervised exercise during neoadjuvant chemoradiation, followed by continued activity before surgery, were more likely to achieve a complete or near-complete pathological response than those receiving usual care.”

“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”

“In this excerpt from Dr. Rhonda Patrick's A4M LongevityFest 2023 keynote, she argues that vigorous exercise is one of the most powerful tools for healthy aging because it can raise cardiorespiratory fitness.”

“In 25,241 adults who reported no structured exercise, a median of three one- or two-minute vigorous lifestyle bouts per day was associated with 38% to 40% lower all-cause and cancer mortality and 48% to 49% lower cardiovascular mortality.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”

“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”
