Which concept supports the idea that nutrition should be personalized rather than one-size-fits-all?

• A. The cumulative burden of stressors on the body at any given time
• B. Addison's disease
• C. Calcium supplementation
• D. Biochemical individuality

Answer: (D)

Biochemical individuality explains why nutrition should be individualized rather than a universal plan. People differ in genetics, enzyme activity, gut microbiota, absorption, health status, and environmental factors, all of which shape how we metabolize and respond to nutrients. Because of these differences, the same diet can support some people beautifully while not meeting others’ needs. This idea leads to tailoring nutrition to an individual’s biochemistry and circumstances—for example, genetic variants that affect folate metabolism or lactose tolerance, microbiome differences that influence nutrient availability, or how medications and disease alter nutrient requirements. The other options don’t capture this principle: one describes how accumulated stress influences health but not personalized nutrient needs; a specific disease; or a single supplement intervention.
