What are Calories? Food Measurements Explained

Do you count calories? Well, even if you answered no, you might be curious to know how we count calories. In essence, counting calories is just using the Atwater system of caloric averages to calculate the total caloric content in our meals. However, this system is old, and inaccurate. So much so, that a serving of almonds is actually 40 calories less in energy content than predicted through the Atwater system. Want to learn more? Of course you do!

Great video, but the music is a bit loud.. its kinda annoying..

[@abelardodiaz6276]

So, atwater isn't in use right, we still burning food to determine their whole calories.

[@OswaldDigestiveClinic]

At Water is still used... but for the general population, I typically recommend using other techniques than calorie counting (chatted about it in my last video ;-) )

Internet Geeks Thanks so much!

Very interessting..... so some of the calories pass thru our body..... It would be interessting if there is a list of food telling how much of the calories that pass thru .... hmm I should be more specific I guess

how do we know how many grams of protein or carbs or fat are in a food?

[@woutdewever5950]

Proteins in food can be measured with the Kjeldahl method, fats can be measured via solvent extraction of GC. Total carbs can be measured by subtracting all known masses from the total mass. But there are many different methods for determining mono/di-/poly-saccharides. You can look it up
