Chemical nature of what we ingest

Distinction between major and minor intakes

Food contains valuable biochemical components that the body extracts through the digestive process to sustain its complex and uninterrupted operation.

These assimilated elements play critical roles, providing everything from the direct combustion required to maintain body heat to the biological foundation for rebuilding cracked cell walls.

Likewise, certain compounds can be retained intact or rapidly transformed into emergency stores, as is often the case with large, dense lipid accumulations.

Classifying this vital raw material by its undeniable volumetric demand, we find a main block grouping sugars, lipids and strong nitrogenous compounds.

In stark contrast, there is another group made up of vitamins and minerals which, although measured in microscopic and subtle portions, are absolutely irreplaceable to enable human life itself and mediate correctly in the innumerable metabolic enzymatic reactions.

Structural functions versus thermal inputs

Looking at the picture from a purely thermal performance perspective, nutrients are sharply divided in biology.

One side has the immense potential to be incinerated in the mitochondria to release raw power.

Here, carbohydrates and fats largely dominate, being the body's undisputed first choice for heavy exertion.

Proteins can also be exceptionally oxidized for this thermal purpose, although their undeniable physiological priority is the reconstruction of worn tissues.

On the opposite side of the street lie the micronutrients, which have no caloric value of their own and cannot generate direct power in the system.

However, the dangerous absence of these metallic and vitamin catalysts completely blocks the internal organic capacity to adequately process the energetic macronutrients ingested.

For its part, the hydric fluid stands alone in a totally independent category, providing no calories but serving as the indispensable universal solvent.

Summary

Every food contains vital biochemical compounds that are actively absorbed by the human organism after comple
