Human nutritional requirements – part 2

I learned a lot about nutrition since my last post. Now I have a clear idea about the energy contribution differences between carbohydrates, proteins and fats; why and how they iodize the table salt; how you can die of an overdose on vitamins; how difficult is to find a good source of alpha-linolenic acid and how can you have a mercury overdose consuming cod liver oil, among other interesting things.

Also, I started working on the script that generates personal Soylent recipes. At the moment, it is able to ask to the user all the necessary data (age, height, weight…) and calculate the daily recommended amount of each nutrient for your personal recipe, according to the Dietary Reference Intake (DRI).

Now I’m working on collecting ingredients and writting their nutritional facts –carbohydrate, protein, fat, vitamin and mineral amounts– in a table. With a huge database of powders and vitamin supplements, it will be easier for the script to calculate the perfect recipe.

Yesterday I discovered the list of the essential nutrients and, for my horror, it seems that the DRI forgets to include the essential amino acids in its recommendation. This means another week of ingredient search, which means another week of delay for my Soylent.

UPDATE: the necessary amounts of essential amino acids was published by the World Health Organization in this PDF, at page 150.
