Nutrition Information

[dfrankland]

It'd be great to specify the nutrition of each ingredient and have that be tabulated to the total nutrition and per serving nutrition.

This would be great. If calculations from input macronutrient data (protein, lipid, carbs) are possible in the program then they could be converted to approximate caloric content using Atwater factors.

Yeah, definitely this was one of my biggest motivators to start Cooklang. It's paradoxical that while the nutrition balance is so important for the health, we have very little feedback on how we're doing.

Slowly we're getting there. But first we need to figure out different units and ingredient density.

Hey @dubadub unfortunately the links here

are not working anymore. Is there any update on Nutrition Information?

I was thinking to use the metadata to put there all Nutrition Information, but looks like most of the parsers supports just string as a value, so I cannot group them. My idea was:

>> nutrition facts: [calories: 221kcal, carbohydrates: 52g, protein: 6g, fat: 1g, cholesterol: 2mg, sodium: 60mg, fiber: 4g, sugar: 41g]

Something which can be easily be parseable to dictionary.

The approach where in the meta I put all the facts in a separate item will require some additional work to group them for nice visualization later.

>> calories: 221kcal
>> carbohydrates: 52g
>> protein: 6g
>> fat: 1g
>> cholesterol: 2mg
>> sodium: 60mg
>> fiber: 4g
>> sugar: 41g

No updates yet, here is one of the links #51 (changed after moving from issues to discussions), second one is gone.

In long-term I think there will be two approaches for nutrition facts:

1. Generating estimates based on ingredients data (with some optimism that we can make computers do their job)
2. Using canonical metadata like you mentioned. Canonical keys for this not defined yet. You can share them with me or update this PR https://github.com/cooklang/spec/pull/69/files#diff-683343bdf93f55ed3cada86151abb8051282e1936e58d4e0a04beca95dff6e51R142-R152 to include this into Roadmap. After that we can update CLI and app to display this data nicely and include it into main spec.

@dubadub To your point on optimism this looks to be an interesting service on a small scale:
https://developer.edamam.com/edamam-nutrition-api

I don't think it is super relevant from a sustainable open source project standpoint but having a connector I could write that would pass it .cook files, get json back and then inserting it into the .cook files (in a canonical way) seems like something that just requires the 'canonical way' to be decided on. :)

It returns something like this:
