On PSL, I see many people propagating that milk is somehow magically good during puberty, but then bad afterwards. Or that it's good to consume afterwards, too.
One factor driving this push to consume milk, is IGF-1 or insulin growth factor one
The igf-1 in even raw milk is around 50-100ng/ml, which is low compared to the body's serum levels which are around 100-400ng/ml, especially the fact it's only a very temporary spike. From those 50-100ng/ml, only around 10% of it is absorbed into the bloodstream, which is an extremely insignificant impact, around 5-10ngl/ml. I was wrong to assume igf01 ages (it barely make s difference on it) you in my discussion with @ameliore in my methylene blue thread, however, other factors in milk contribute to aging such as the carbohydrate profile. Milk is 4.7% carbohydrate, 3.3% protein, and 3.5%fat, making it a carb heavy food option. These carbohydrates will glycate and increase Advanced Glycation End Products, which will effectively age you. While it's high in calcium, so are other foods https://www.dietaryguidelines.gov/food-sources-calcium. All other building blocks, are also found in other foods. There is 0 proof that consuming calcium above the RDA has any substantial effects on growth, all studies done on calcium supplementation and increased consumption were done in children who had inadequate calcium intake

Going outside of a scientific aging perspective, the advent of dairy is very new. Domestication of these animals alone occurred around 5-10 thousand years ago, which is extremely insignificant. Even this, doesn't mean that we were consuming it just because we domesticated them.

That's around 5%..

Calcium Intake and Nutritional Adequacy in Spanish Children: The ANIVA Study
Calcium is an important nutrient for child development. The main objective of this study was to assess calcium intake and its adequacy with dietary reference intake (DRI) in Spanish children. The ANIVA (Antropometría y Nutrición Infantil de Valencia) study is a descriptive cross-sectional study...
