What key shift occurred as nutritional science moved beyond identifying single-nutrient deficiencies?
Answer
It moved toward understanding complex metabolic pathways.
The early phase of nutritional science focused heavily on identifying and correcting deficiencies related to single nutrients, such as identifying lack of Vitamin C leading to scurvy. The transition toward modern, evidence-based personalization necessitated a much deeper understanding. This required researchers to move past simple deficiency remediation to investigating the intricate and interconnected complex metabolic pathways within the body. This shift enabled the scientific investigation into why individuals process the same diet differently, leading to the development of fields like nutrigenomics and metabolomics.
