Your body has 60,000 miles of blood vessels, enough to circle Earth twice. Angiogenesis grows and maintains this network. Green tea, tomatoes, soy, and watermelon support it. Trans fats, processed meats, sugary drinks, and salt harm it.  #Angiogenesis

🧬 Immunotherapy works by restoring your body's own immune defenses to fight cancer. Even in people in their 80s and 90s it can lead to complete remissions.

Breakthroughs are happening every month. 🌿

Your metabolism isn't the luck of the draw. A 2021 Duke study of 6,421 people across 29 countries found it moves through four phases in a lifetime, staying stable from age 20 to 60.

Body fat, activity, sleep, and diet all shape it. #Metabolism

🫒 Extra virgin olive oil contains polyphenols like hydroxytyrosol and oleocanthal that help regulate inflammation and support immune balance.

Use it as your primary cooking oil, drizzle it over food, or enjoy a few tablespoons a day. 🌿

Visceral fat, the fat you can't see, hides deep in your abdomen and drives inflammation, insulin resistance, and chronic disease. Diet matters: deli meat, fried foods, beer, liquor, and added sugars raise it. #VisceralFat

Your nervous system is built to recover from stress. The vagus nerve helps regulate that recovery. To support it: try a physiological sigh, slow exhales, humming, a brisk walk, cold water on your face, or green tea and chamomile. Train your body to recover better. #VagusNerve

🫐 One cup of blueberries regularly supports immune cell function and helps regulate inflammatory signaling through powerful bioactives called anthocyanins.

Fresh or frozen. Both work. 🌿

🧠 My 5 step sleep framework. Dim lights at night, cut caffeine in the afternoon, exercise daily, keep your room cool and dark, and get morning unlight to reset your sleep clock.

Protect your brain with sleep. 🌿

🧬 Diet helps shape your immune system every day. Think of immunity as a volume dial, not a switch. Bioactives like anthocyanins, sulforaphane, beta-D-glucan, and capsaicin can help support healthy immune function. Small daily choices add up.

🌅 Just 10 to 20 minutes of morning light resets your internal clock, regulates melatonin, and helps you sleep better that night.

No sun needed. Just step outside. 🌿

Your stem cells help maintain and repair your blood vessels—and what you eat can influence this regenerative system. Here are 8 habits to keep them active. #StemCells #HeartHealth

[Dr. William Li @drwilliamli]

🧠 Caffeine blocks adenosine, a chemical that builds up the longer you’re awake and increases your drive for sleep. It can make you feel more alert, but it doesn’t erase your need for sleep. That morning coffee can mask fatigue, but it can’t replace restorative sleep.

🔬 Cancer cells cannot grow without a blood supply, and some everyday foods contain natural compounds studied for their ability to help regulate the growth of new blood vessels.

Small choices can help support your body’s natural health defenses over time.

🔥 Chronic inflammation is a common thread in heart disease, diabetes, and certain cancers.

Your gut is home to a major part of your immune system, where immune cells interact with your microbiome. Supporting that relationship can help keep inflammation in check.

🍵 L theanine in green tea activates alpha brain waves, the same pattern seen during meditation.

One to three cups a day for a natural meditative calm and better mental focus. 🌿

🧬 DNA takes daily damage from UV rays, microplastics, and preservatives. Unrepaired, it can mutate.

Good news: diet helps repair it. Kiwi boosts repair, green tea activates tumor suppressor genes, sleep and exercise slow telomere shrinkage.

🧠 High-intensity workouts create a short-term stress response in your body. If you’re already overwhelmed, try Zone 2 walking or controlled strength training.

Move, recover, then build from there. 🌿

🌬️ The physiological sigh. Deep inhale through your nose, second short inhale, then a long slow exhale.

Do it a few times and feel the tension shift almost immediately.  🌿

🐟 You don't need much seafood to get meaningful amounts of omega-3s. Just 4 shrimp, 3 oysters, 1 tbsp salmon roe, or a bite-size forkful of sardines or mackerel provides about 284 mg—the amount linked to benefits in one clinical study.

🩸 Aging affects your blood vessels, too. As nitric oxide declines, blood flow becomes less efficient, contributing to fatigue and brain fog. Support it with beets, arugula, spinach, blueberries, dark chocolate, apples, onions, and barley. #NitricOxide
