Diet prescription - LC-FAOD

Establishing a prescription is done in a stepwise manner:

Step 1	Fill the total fat requirements and the distribution for LCT and MCT, depending on the phenotype of the LC-FAOD
Step 2	Fill in energy and protein requirements
Step 3	Adjust fluid volume to meet requirements
Step 4	Calculate vitamin, mineral and trace-element content of the final mixture, adjust or supplement as needed

Dietary recommendations:

Protein recommendations

For healthy individuals, protein recommendations are based on the rates of growth, protein deposition for children of different age groups, the amino acid composition of whole body protein, as well as the efficiency of dietary protein utilization¹ and more recently by a stable isotopic technique.²

At least 1% of total energy from LA and 0.2% from ALA
