Snapshot · On Purpose with Jay Shetty
In mouse studies, aspartame-induced anxiety-like behaviors persisted for two generations in offspring who were never directly exposed to aspartame, suggesting epigenetic transmission.

Jay Shetty asks which chemicals are most convincingly linked to brain harm, and Palmer navigates carefully between scientific honesty and the political reality that food companies fund scientists to cast doubt on such findings. He anchors his answer in the most striking animal data available: mice given normal doses of aspartame — equivalent to a few Diet Cokes a day — developed anxiety-like behaviours confirmed by amygdala hyperactivation. Crucially, those behaviours persisted in their pups and grandpups, none of whom were exposed to aspartame.

More alarming: those anxiety-like behavi…" 1:16:30 The mechanism is epigenetic change transmitted across generations. Large epidemiological studies in humans show an association between high artificial sweetener consumption and anxiety, depression, and broader mental health conditions. Palmer is careful with language — this is probabilistic, not deterministic — but his practical recommendation is clear: if you want to protect your brain, eat real food, not food containing chemicals that were never real food. His closing advice is the throughline of the entire episode.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
