Excessive Leucine-mTORC1-Signalling of Cow Milk-Based Infant Formula: The Missing Link to Understand Early Childhood Obesity

Table 1

Leucine content of mammalian milk and growth rate.

Species	Protein content of milk (g/100 mL)	Leucine content of milk (mg/100 mL)	Days (n) for doubling birth weight^3
Rat^1	8.7	799	4
Cow^1	3.4	333	40
Infant formula (HP)^2	3.2	308	?
Infant formula (LP)^2	1.6	154	?
Human milk^2	1.2	104	180

¹Data according to Davis et al. [37]; ²HP high protein followon infant formula; LP low protein followon infant formula at 6 months of age [39]. ³Data according to Bounous et al. [36].
