Key Moments
Sunlight as essential nutrient for human health
Saladino makes a comprehensive case that sunlight is essential for optimal human health, discussing benefits for mood, vitamin D production, endorphins, and nitric oxide release, arguing it should be considered a nutrient alongside diet.
"I would say essential for humans, that it is a nutrient, that we could even expand the conceptualization of an animal-based diet to be organs, meat, fruit, honey, raw dairy, and ultraviolet sunlight outside. But when I make that case that sunlight is so essential and so valuable for humans, I'm sure many people will say, but Paul, doesn't sunlight cause skin cancer? So I will talk then about melanoma, a skin cancer that is canonically thought of as a sun-associated."
Vitamin D from sunlight vs supplementation
Deep dive into vitamin D metabolism from sunlight, showing how UVB converts 7-dehydrocholesterol to vitamin D3, and reviewing interventional studies showing vitamin D supplementation reduces cancer risk and improves pregnancy outcomes.
"Go sun your balls, or I don't know what you call it for ladies, but you guys get the idea. What is up, truth seekers? Welcome to another edition of the Fundamental Health Podcast. It is now May, and I wanted to talk about sunlight because this is something that is on my mind a lot these days. Here in Costa Rica, we're getting into the rainy season, but the days are still getting longer because we're in the northern hemisphere. Many of you listening to this are also in the northern hemisphere, and you are approaching bathing suit, beach, and bikini season. So I I want to start the podcast with a consideration of the benefits of sunlight, supplemental vitamin D, and ultraviolet light. And we'll look at both interventional and observational studies along the way to explore the benefits of sunlight."
