- Water: Often overlooked, water is crucial for hydration, nutrient transport, and countless other metabolic processes.
The process of nutrition involves several stages, from ingestion to excretion:
- Ingestion: Taking food into the body.

- Excretion: Eliminating waste products.
Effective nutrition ensures each of these steps functions optimally. A deficiency in even one nutrient can disrupt this process and lead to health problems.
