I have made a small protein calculator program. You just put in how much protein your food has and how much protein you want to consume for one day. For example: Proteinpercentage: 22 grams. Protein amount to consume: 62 grams. Result: You need 281 grams. Which means you need 281 grams of that food which you are calculating.
