innacurate calorie ratios, and nutrient density ratio
So for 500g of spinach there is 14.3 g of protein.115 calories in total. If 1 g of protein = 4 calories how come fitday.com is registering that this food is only 30% protein by calorie percentage? It shd be more closer to 50% shdn't it?
Also is there a way to count percentages by density or at laest weight? Im not talking about the more popular versions of "nutrient density" which is nutrient per calories, which tehere is no measuring process developed for yet. Im speaking more like % by weigght or at volume, or both at the same time.
I also noticed that spinach does not list as much Iron as it should.
From everything else I'm reading online, Spinach should have about 10-12 mg Iron for 2 c, but fitday only has 1.6 listed.
