Based on YT video I Ate 720 Eggs in 1 Month. Here's What Happened to my Cholesterol:

• Nick Norwitz, a Harvard medical student with a doctorate in human cerebral metabolism, ate 720 eggs in one month, averaging 24 eggs per day, to test the effects on his cholesterol levels.
• Contrary to popular belief that eggs increase bad cholesterol (LDL), his LDL cholesterol dropped during the experiment. It decreased by 2% in the first two weeks and then by an additional 18% in the next two weeks.
• The high cholesterol intake (about 133,000 mg from eggs) did not raise his blood cholesterol. This was explained by a hormone called cholesin, released when cholesterol binds to receptors in the gut, which signals the liver to reduce cholesterol production, maintaining balance in the body.
• During the last two weeks, he also increased carbohydrate intake slightly, which further helped reduce LDL levels, possibly in combination with other dietary elements like fruits.
• The experiment challenges the long-held medical advice limiting egg consumption due to cholesterol concerns, suggesting that dietary cholesterol may not significantly impact blood cholesterol levels in healthy individuals.
• Norwitz documented his experiment publicly on YouTube, sparking discussions on nutrition and metabolism and encouraging re-evaluation of egg consumption guidelines.
• Eggs are a veritable treasure trove of nutrients: harmful vitamins A, D, E, and K, harmful B vitamins, calcium, phosphorus, iron, sodium, and potassium. However, even such a valuable product should not replace other essential nutrients.

so strange... i was searching 'gold' and came across this phrase inverted as one of Leopold's musings. then i realized a version of this phrase — gold by bronze, or bronze by gold — recurs throughout the novel.
