Avocado

Spanish conquistadores wrote documents using red-brown ink made from avocado seeds.

avocado contains a compound called avocatin B that selectively kills leukemia stem cells without harming healthy bone marrow cells.
leukemia stem cells are the cells responsible for cancer coming back after chemotherapy.
avocado extracts kill breast, colon, liver, oral, esophageal, and prostate cancer cells through mitochondrial disruption and triggering apoptosis. the seed is the most active part for anticancer purposes.

avocado leaf extract rebuilds the pancreatic cells that produce insulin.
avocado leaf extracts and avocatin B from the seed lower blood sugar through four mechanisms at once: blocking carb-digesting enzymes (alpha-amylase and alpha-glucosidase), improving insulin sensitivity, AND actually regenerating the pancreatic cells that produce insulin.
avocado also contains mannoheptulose, a unique 7-carbon sugar with its own insulin-modulating activity being researched as a caloric restriction mimetic for longevity.

avocado contains lutein and zeaxanthin, the two carotenoids your retina actively concentrates in the macula to protect against age-related macular degeneration, cataracts, and blue light damage.
its high fat content also dramatically boosts your absorption of lutein from other foods (like kale or spinach) when eaten together — by 3-15x in some studies. eating avocado with lutein rich food makes the food 3-15 times more effective for eye protection.

avocado contains compounds that block the enzyme that makes melanin (tyrosinase) and stimulate collagen production. applied topically, avocado oil penetrates deeper than most natural oils and carries antioxidants down to the layer where your collagen-making cells live. used regularly, it lightens dark spots, smooths wrinkles, and improves skin hydration and elasticity.

topical avocado oil heals wounds faster by reducing inflammation, preventing infection, supplying vitamin E for skin regeneration, and stimulating collagen production. also reduces pain and damage from UV burns.

avocado seed extract kills intestinal parasites (amoebic dysentery, giardia, trichomonas, roundworms), tuberculosis bacteria (including the antibiotic-resistant strains that conventional drugs fail against), H. pylori (the stomach ulcer bacteria), Staph aureus, and Candida yeast.
the peel kills mosquito larvae including the species that spread malaria, dengue, and Zika.

avocado protects the liver from chemical damage and prevents the progression from chronic liver injury to liver cancer.

maternal avocado consumption improves offspring memory and brain development.
lutein concentrates in the brain (not just the eye) where it's linked to better cognition and lower Alzheimer's risk.

improves blood circulation, reduces blood pressure, and helps with hypertension.

the fiber in avocado leaves may help with digestion and gut health.

Quercetin and flavonoids in avocado leaves may help flush out toxins and free radicals.

has boron, that binds to fluoride and removes it from the body. boron binds to the fluoride ion and makes it unabsorbable. It also prevents fluoride from binding to calcium.
boron is a trace mineral that is essential for bone, joint, and dental health.
without boron, fluoride accumulates in bone, teeth, and the pineal gland, where it calcifies tissue and causes long-term damage including skeletal fluorosis, dental fluorosis, and pineal calcification.

keeps you full and is high in fat, mainly healthy monounsaturated fat.

avocado contains vitamin K1, which is essential for actually getting calcium INTO your bones (not just consuming it). vitamin K activates osteocalcin, the protein that grabs calcium and locks it into bone matrix. without enough vitamin K, calcium floats around in your blood and arteries instead of going to bones, which is exactly why so many people have weak bones AND calcified arteries at the same time.

one of the most efficient biodiesel feedstocks in the world. the seed oil converts to biodiesel at 96% yield (one of the highest documented for any plant), with a cetane rating of 62.2 — way above what regular diesel requires (47). the key advantage is that biodiesel is made from the SEEDS AND PEELS, which are normally thrown away as waste from the avocado industry.
so you get clean renewable fuel without competing with food production or needing new farmland.
avocado oil also has the highest smoke point of any common cooking oil (271°C), making it the best oil for high-heat cooking. it penetrates skin better than almost any other natural oil because its fatty acid profile matches human sebum closely.
