Compute and display glycemic index

[CharlesNepote]

While it is possible to enter the glycemic index in the nutrients' form, we could try to compute and display the glycemic index, based on the ingredients.

Either we can find an open data database, either we could start to collect the values from different scientific articles (eg. for commonly consumed Thai fruits).

Some resources [to be completed and reviewed]:

• https://academic.oup.com/ajcn/article/114/5/1625/6320814
• https://glycemicindex.com/
• https://foodstruct.com/glycemic-index-chart

Some important facts:

• glycemic index varies from different species: different banana or lentil species can have a glycemic index which can significantly vary (eg. from 23 to 30 for bananas as stated in this article)
