Key ideas in How Your Body Uses Food
- Carbohydrates from foods like grains, fruit, and starchy vegetables break down during digestion into simple glucose units
- The body cannot circulate complex starches directly; they must be broken into simple glucose first
- Glucose enters the bloodstream through the intestines and acts as the body's primary circulating fuel for immediate energy needs
- Rising blood glucose prompts the pancreas to secrete insulin into the bloodstream
- Insulin acts like a cellular key, signaling muscle and liver cells to take up glucose from the blood
- Once inside cells, glucose is either burned immediately for energy or packed away into storage for later
- Liquid and simple sugars rush out of the stomach and absorb into the blood very quickly, creating a sharp spike in blood sugar
- A steep spike triggers an aggressive release of insulin, which pulls sugar out of circulation rapidly
- That rapid plunge leaves blood sugar temporarily low, triggering an energy crash, shakiness, and sudden cravings to eat again
- Protein, dietary fat, and fiber all slow down how quickly the stomach empties into the intestines
- Slowing down digestion and absorption turns a sharp spike into a gradual, steady rise in circulating blood glucose
- Refined carbs eaten without fat, protein, or fiber digest very quickly and lead to steep spikes
- Active, contracting muscles can pull glucose directly out of the blood stream to burn for fuel without waiting on heavy insulin signals
- A brief, gentle walk taken within 30 to 45 minutes after eating blunts the blood sugar peak
- Sitting completely still leaves the pancreas to do all the work with high insulin surges, increasing the chance of a post-meal slump
- Protein is dismantled into amino acids, which serve as construction blocks to repair tissues and create bodily enzymes
