Much of what we know about our diet through evolution has been skewed by the sheer availability of these foods in our environment. Human breast milk may be a better indicator of what macros the body places importance upon. Especially since these macros shift at different phases of lactation. Protein ratios shift between whey and casein. The amount and type of fats shift. And the carbohydrate concentration shifts over time as well. While breast feeding in and up to the first 12 months has been highly studied, research of continuing to breastfeed past 24 months and up to 48 months had been lacking. A group of scientist set out to discover how the macronutrient ratios shifted in mother’s milk when continuing to breastfeed up...
