Feature request: retention factors for individual ingredients
When making recipes, it is impossible to weight the individual ingredients once cooked, so one has to weight them raw. A lots of things happen while cooking (vitamins are inequally lost, some of them increase greatly such a beta-carotene, carbs structures change, minerals can be partially lost...) depending on how it's cooked. Since ages, USDA has published a Table of Nutrient Retention Factors. This option would allow the user to enter ingredients based on their raw weight and select for each of them how they're cooked (boiled, steamed, baked, fried, etc.), giving a better picture of nutrients actually ingested. That would be a huge step forward imo. This could be implemented in recipes but also in the diary for convenience.
