About Food X-Ray

Pick a food and a centrifuge separates a 100 g sample into what it is made of: water, protein, fat, sugars, starch, fiber, ash (minerals) and alcohol. Each part is poured into its own vessel and labeled with its weight in grams.

Where the numbers come from

Every number is a published value from the U.S. Department of Agriculture's FoodData Central (SR Legacy, April 2018), which is in the public domain. Each food is one USDA record. "n/a" means USDA did not measure that part for this food. "Other carbs" is carbohydrate USDA reports without splitting it into sugar, starch and fiber.

What the picture is and is not

The layers settle in order of their real density (minerals at the bottom, oil and alcohol on top). Each vessel is sized so its 100 g fills the same volume as in the sample tube. The centrifuge, the colors and the shapes are an illustration; a real lab would need chemistry, not just spinning, to pull these apart.
