Key Nutrients & Their Functions

I, GP, am always amazed that people do not know the functions that their food items (& nutrients within those items) play. That said, many adults don't even know what nutrients are derived from foods they're eating, despite most being clearly labeled. Below is a list of our key nutrients and the main function that they perform. Click on each for more in-depth information.

Protein – repair & growth of tissue

Carbohydrate – primary energy source

Fat – secondary energy source

Vitamins & Minerals – regulate metabolic processes.

Water – transportation of other nutrients

Best regards,

Amino Acids - L-Aspartic Acid

Something (L-Aspartic Acid) that's cropped up a few times recently during the joyous explanation of the Krebs Cyle (Citric Acid Cycle), as oxidation of L-Aspartic Acid plays an intermediate role in the eventual production of ATP.

Fatigue can be experienced if levels of L-Aspartic Acid are too low. Again (as mentioned with other amino acids), your general sources of protein - dairy products, beef, poultry, eggs - are all sources of L-Aspartic Acid and should provide enough L-Aspartic Acid. L-Aspartic Acid's relationship (if too low) to fatigue means that it's often advertised in supplement form to reduce exercise induced fatigue and increase stamina. Again, L-Aspartic Acid's individual importance does not outweigh the recovery benefits of a varied and sufficient intake of protein.
