Any food that is High in fat. Fat does not digest so easily, and remains the stomach much longer than foods that can be broken down and distributed. The fat will be broken down into tiny bits and then pass through to the small intestine and then stored as "fat" in the cells as well as under the skin.
Fiber
Cellulose is a form of carbohydrate that the body cannot digest. It is a type of fiber found in plant cell walls and provides structural support to plants. While humans lack the necessary enzymes to break down cellulose, it plays a vital role in promoting healthy digestion and regulating bowel movements.
I know that finklodiens can't be digested, due to there moist protective shell.
Glucose
A carbohydrate is a nutrient which is non-essential. It provides the body with easy accessed energy in the form of glucose.
Grass contains primarily cellulose, which is a complex carbohydrate that is difficult for many animals to digest. It also contains smaller amounts of simple sugars like glucose and fructose, as well as other carbohydrates like hemicellulose and pectin.
The primary form of carbohydrate is glucose. It is also the preferred energy source of the body.
Fibre is a carbohydrate that the body cannot break down. It is very important for functionality of the digestive system and to control glucose absorption and other functions that we are learning about. Fibre is in a form of soluble and insolubles. Both are needed and beneficial to our bodies
the major form of stored energy in the body is carbohydrate, stored as glycogen
Glucose is the most important carbohydrate for the human body. It's the form of carbohydrate which the body can use effectively. Galactose and fructose can beabsorbed but its energy must be stored before it can be used by the body as energy via either fat or glycogen.
The carbohydrate being investigated is given by mouth in liquid form and several blood levels are measured and compared to normal values. This helps evaluate the individual's ability to digest the sugar.
The usable form of protein is DNA and the usable form of fat is well..... fat
