This week, Dr. Kahn discussed a case study involving a 30-year-old man with newly discovered, very high cholesterol. The implications of heart disease in young adults—backed by a recent paper from the CARDIA study group—suggest that early intervention, beginning with lifestyle changes, should be offered, along with follow-up lab testing. The Portfolio Diet plan would be a strong starting point on the journey toward a more plant-based diet.

Other topics covered include the risks of diet soda, the health impacts of being a night owl, coffee consumption for atrial fibrillation patients, the role of genetics in longevity, plant-based diets for kidney health, and red light therapy for brain illness and trauma.

Thanks to getfreshDRKAHN.com for the $1 offer on a bottle of fresh-pressed olive oil from some of the finest estates. EXTENDED SHOWNOTES: Dr. Kahn also touched on several additional topics during the episode. He discussed olive oil tasting and shipping, encouraging listeners to sign up before the current shipment from Italy ends and explaining how tasting fresh olive oil helps assess quality. Red light therapy came up in the context of brain injury, including a study showing potential benefits from nasal exposure in college athletes with repeated head trauma. He also mentioned advocacy efforts to promote routine coronary calcium scoring starting at age 45. Several studies on diet and longevity were reviewed, including research showing that plant-forward diets are associated with better kidney health and that genetics may account for up to 50% of longevity—though lifestyle choices still matter greatly. Dr. Kahn also covered caffeine and heart rhythm, noting research where coffee consumption was linked to fewer episodes of atrial fibrillation, while diet soda was associated with a higher risk of dementia.

Finally, he discussed sleep patterns, citing data suggesting that night owls face higher cardiovascular risks than early risers.
