Summary
Highlights
Lycopene in tomatoes is a powerful antioxidant that can starve cancers, slow cellular aging, and protect DNA. However, raw tomatoes offer only about 20% absorption of lycopene. Heating tomatoes, especially with a little olive oil, changes the chemical structure of lycopene, increasing its absorption by the body to about 80% due to its fat-soluble nature.
Turmeric contains curcumin, a natural chemical with anti-inflammatory, antioxidant, and anti-cancer properties that also benefits gut microbiome and stem cells. While potent, the body doesn't absorb curcumin well on its own. Adding fresh cracked black pepper, which contains piperine, significantly enhances the body's ability to absorb curcumin, creating a beneficial 'one-two punch'.
Green tea contains catechins (EGCG), polyphenols that act as relaxants, lower stress, help lipids, fight cancer, and reduce inflammation. While easily absorbed when tea is consumed plain, adding cow dairy (milk or cream) can hinder this. The fat molecules in dairy form micelles that trap catechins, preventing their absorption in the stomach and leading to them being passed out of the body. Nut milks, however, do not have this effect. There's also a special 'milk tea' from Taiwan that naturally tastes like it has dairy due to unique growing conditions, despite being pure tea leaves.
Dr. Li emphasizes that whole foods are generally superior to supplements because they provide a broader spectrum of beneficial compounds like fiber, polyphenols, and peptides. However, supplements are valuable for topping off nutrients when dietary intake is insufficient. He particularly recommends high-quality omega-3 fatty acid supplements for those who don't regularly consume oily fish and vitamin D3, especially for individuals in northern hemispheres with limited sun exposure. A tip for increasing vitamin D in mushrooms is to slice them and expose them to sunlight.
