Mindsip insights from this episode:
Maintain slippery blood vessel linings for optimal blood flow
The inner lining of your blood vessels should be incredibly slippery, like a newly polished ice rink, to allow blood cells to flow without sticking.
Activate brown fat to burn harmful white fat
Your body has beneficial 'brown fat' which, when activated, acts like a furnace to burn down harmful 'white fat,' especially inflammatory visceral fat.
Protect blood vessels with polyphenols and sulforaphanes from leafy greens
Polyphenols and sulforaphanes from leafy greens are absorbed into your bloodstream, where they lower oxidative stress and inflammation to protect blood vessel walls.
Activate metabolism with polyphenol-rich foods and beverages
Certain foods and beverages, including green tea and coffee, contain polyphenols that can activate your brown fat to burn down harmful white fat.
Practice self-compassion and return to your healthy path
It's important to have self-compassion and allow yourself to occasionally wander off your healthy path, as long as you get back on it.
Leverage polyphenols in tea and coffee to enhance heart health
Polyphenols in tea (EGCG) and coffee (chlorogenic acid) are beneficial for blood vessels because they lower inflammation and oxidative stress.
