How the 7 Nutrients Work Together
These seven types of nutrition do not work in isolation. They interact in complex ways to keep your body functioning optimally:
- 1.Fats help absorb vitamins - Vitamins A, D, E, and K are fat-soluble, meaning you need dietary fat to absorb them properly.
- 2.Protein needs carbs for energy - Without adequate carbohydrates, your body may break down protein for energy instead of using it for muscle repair.
- 3.Water transports all nutrients - Proper hydration ensures nutrients reach every cell in your body efficiently.
- 4.Fiber regulates carb absorption - Fiber slows down the absorption of sugars, preventing blood sugar spikes.
- 5.Minerals support vitamin function - Many vitamins require minerals as cofactors to work properly.
