This is something I can see my self using.
-Possible to add a 000g to the sliders of the left to be able to find foods based on a nutrient's content in grams?
-big ask but - could you add a way to sort by average price/calorie or by standard weight (g, ounces, etc)? (example) would love to be able to find highest protein lowest carb foods, sorted by price.
-how are the %s calculated, % of of daily recommended value? % of nutrient to total calories in food? Would like more clarification.
note: might want to break up some of the recipies into smaller components - e.g. right now when I set protein slider up all the way up and "avoid foods with" carb slider all the way down, tuna salad sandwhich is one of the top recipes (above sauteeed spinach). Would like to see the actual breakdown because I find it hard to believe an entire sandwhich has fewer carbs than spinach.
Otherwise, good work! will keep my eye on it.
As for percentage of daily recommended value, these mostly come from the standard recommendations, for instance 28g of fiber per 2000 calories, etc.
