Getting sun exposure in proper doses can be beneficial for humans as sunlight is considered a nutrient. Proper sun exposure can lead to improved behavior, focus, and energy levels, as demonstrated by the speaker's son after taking supplements derived from heart and soil sources.
Discussion revolves around skincare, sunscreen, and protecting the skin from harmful exposure. The podcast emphasizes the importance of being mindful of what you apply to your skin, attributing harmful effects to products containing linoleic acid, a common component in moisturizers and sunscreens.
Research indicates a correlation between high intake of polyunsaturated fats, particularly omega-6 fats like linoleic acid, and increased risk of various skin cancers. Furthermore, studies highlight the detrimental effects of linoleic acid on skin inflammation, emphasizing the negative impact of seed oils on skin health.
Consuming linoleic acid is linked to worsened melanoma, as demonstrated by high levels of linoleic acid in fatty tissues correlating with an increased risk of skin cancer. The presence of linoleic acid in cell membranes can lead to inflammation in the skin, which is a known precursor to skin cancers and premature aging. Sunflower oil and other products containing high linoleic acid should be avoided in both diet and skincare products to protect skin health.
Supporting skin health involves considerations such as collagen intake, zinc for wound repair, and beneficial saturated fats found in animal products. Biotin from liver and iron from meat and organs play roles in skin barrier protection and wound healing. An animal-based diet emphasizing organs, meats, fruit, honey, and raw dairy can reduce skin inflammation, contributing to improved skin health and conditions like acne.
This week, Paul talks all about skin: how to take care of your skin, what you should and should not eat to have healthy, radiant skin, how to heal skin conditions like eczema, psoriasis and acne. He shares why the sun itself is highly beneficial for our skin and overall health, and although the sun deftly is not harming you, your sunscreen may be.
