A nutrition professional working inside food manufacturing or retail companies to guide the nutritional quality of products. The industry nutritionist reviews recipes for fat, salt, sugar, and micronutrient content, ensures nutrition labels and health claims comply with regulation, and supports new product development with evidence-based advice. The role bridges science and commerce: translating dietary guidelines into feasible formulations, responding to consumer health concerns, and contributing to company nutrition policies such as salt-reduction targets. It requires formal nutrition training plus an understanding of manufacturing constraints, marketing law, and shifting consumer expectations around health.
