>>If there is any information domain were it’s harder to figure out the real truth than current US politics, it’s “nutrition science” I recently dug out some original USDA documents from the 19th century to research[1] the origins of nutritional science in the US. W. O. Atwater, the guy who introduced things like Calories (equal to kcal), macros, and "dietetics" has had a huge impact on nutritional science, including modern food labelling and things like the simplified conversion of fat to 9 Calories/gram and protein/carbs to 4 Calories/gram.
Atwater himself was very much influenced to introduce these to the American public by his German professors (he did a postdoc there), who were themselves looking into making nutrition "efficient - for cattle and humans alike. I found the history quite fascinating, it gets to the "origins" of the idea of quantifying food. [1]https://blog.jumpycatapp.com/calorie-counting-weight-loss-hi... |
