How do food producers measure the exact amount of carbs, proteins, vitamins etc. in a piece of food?

Answer 1

Also, keep in mind that food is made up of carbs, protein, and fat. Those three things determine how many calories are in your food.

1 gram of carb = 4 calories /
1 gram of protein = 4 calories /
1 gram of fat = 9 calories

So, you add/multiply carbsx4 + gramsx4 + fatx9, you should get the calorie count for your serving of food. If you are looking at your label and it doesn’t add up, then you probably shouldn’t eat that food. They are lying about something.

This is how it was explained to me by a nutritionist and may be an over simplified way of how things really work.
