The Biology of Breast Milk
“Heavy metals and prescription drugs, especially those used to treat cancer, readily transfer to breast milk and pose considerable threats due to an infant's limited capacity to metabolize drugs. But commonly used "social drugs," such as alcohol, nicotine, caffeine, and cannabis all carry some risk to a breastfed infant, as well.”
Exercising, drinking coffee and having sex are triggers that raise rupture risks for brain aneurysm, retrospective study finds. (2011)
“"Reducing caffeine consumption or treating constipated patients with unruptured IAs with laxatives may lower the risk of subarachnoid hemorrhage," Vlak said. "Whether prescribing antihypertensive drugs to patients with unruptured IAs is beneficial in terms of preventing aneurysmal rupture still needs to be further investigated."”
Polyphenols found in tea and coffee may reduce the risk of diabetes.
“Eleven healthy men drank a beverage that contained either polyphenols from tea (catechins) and coffee (chlorogenic acids) or a placebo every day for three weeks. Both beverages provided 119 milligrams of caffeine – a little more than the amount present in one cup of coffee.”
Plant-based dietary components may prevent cognitive decline.
“Conversely, metabolites derived from caffeine, alcohol, and artificial sweeteners appeared to promote cognitive decline. These findings suggest that specific plant-based dietary components protect against cognitive decline and support the rationale for a plant-rich diet.”
THC from a single use of cannabis accumulates in breast milk for up to 12 hours in breastfeeding women.
“Other harmful compounds, including nicotine, caffeine, and heavy metals, can pass into breast milk, too. Learn more about breast milk and breastfeeding in our overview article. Read full publication.”
Early cannabis exposure disrupts brain development, reducing dendritic branching and neural spine complexity in areas critical for learning and emotional regulation.
“Researchers exposed adolescent male mice to THC and then analyzed changes in gene expression and brain cell structure within the cerebral cortex—a brain region responsible for memory, thinking, learning, reasoning, problem-solving, emotions, consciousness, and sensory functions.”
Drinking black coffee may reduce the likelihood of early death by up to 17%.
“But if you load it up with sugar and cream, you might negate the benefits. A recent study found that people who drank black coffee or coffee with minimal sugar and saturated fat were up to 17% less likely to die early than those who didn't drink coffee.”
Chronic cannabis use, whether smoked or ingested, impairs arterial function—an early red flag for cardiovascular disease.
“Like tobacco smoke, cannabis smoke contains numerous toxic compounds and fine particles known to impair cardiovascular function. A recent study found that regular cannabis users had roughly 40% lower arterial function than nonusers, raising concerns about the long-term vascular consequences of chronic use.”
