Background & Nutritional Philosophy
After graduating with a degree in Veterinary Medicine in Brazil, Lucas pursued postgraduate specialisation in animal nutrition and behavioural science. During years of working with pet guardians, one persistent systemic challenge became clear: the massive disconnect between what pet food manufacturers state on commercial packaging and what owners actually understand.
Commercial packaging is frequently clouded by marketing terms—such as “meat meal”, “animal derivatives”, and unquantified botanical claims—that obscure real ingredient quality. PetFoodFix was founded to bring absolute scientific transparency to pet food selection, allowing owners to evaluate foods against published international nutritional standards.
Methodology & Systems Architecture
At PetFoodFix, Lucas oversees the formulation and continuous audit of deterministic evaluation algorithms:
Food Quality Framework
Designed the four-band scoring rubric (Bad, Regular, Good, Very Good) evaluating protein transparency, ingredient declaration clarity, and additive safety.
Nutritional Standards
Ensures caloric and portion calculation models rigorously adhere to FEDIAF 2025 and NRC (National Research Council) energy requirement equations.
Editorial Peer Review
Conducts mandatory veterinary safety audits on all published nutritional guides, verifying citation integrity and non-diagnostic educational tone.
Clinical Red-Flag Triage
Engineered the pre-checkout safety screening rules that halt automated recommendations and refer symptomatic dogs immediately to a qualified veterinary surgeon.
