En los pasillos de los supermercados de bajo coste, una promesa reluce en cada etiqueta: proteína abundante a precio accesible. Pero el nutricionista Pablo Ojeda advierte que detrás de esos números se esconde una práctica legal aunque engañosa —el amino-spiking— que infla las cifras sin aportar el valor nutricional real que el cuerpo necesita. Como tantas veces en la historia del consumo moderno, la brecha entre lo que se vende y lo que se recibe nos recuerda que la conveniencia tiene un precio que no siempre aparece en el ticket.

Consumers purchasing budget high-protein products may unknowingly receive lower-quality protein despite label claims, leading to wasted spending on ineffective nutrition. This erodes trust in budget retailers' private-label health products and may shift demand toward premium brands or whole foods like eggs and legumes.
Potential regulatory response could include stricter labeling requirements mandating amino acid profiles on all protein products, clearer definitions of 'high-protein' claims, or restrictions on amino-spiking practices. EU/Spanish food authorities may need to establish standardized testing protocols and enforcement mechanisms.
