Which statement about biochemical individuality is true?

Which statement about biochemical individuality is true?

• A. There is a universal diet for all individuals
• B. Nutritional needs vary based on biochemistry; no one diet fits all
• C. Everyone should take supplements
• D. Diet has no effect on disease risk

Answer: (B)

Biochemical individuality means that people’s nutrient needs reflect their unique biochemistry. Genetic differences shape how we metabolize fats, proteins, and micronutrients; enzyme activity, metabolic pathways, and nutrient requirements vary from person to person. The gut microbiome, age, health status, medications, and lifestyle further influence nutrient absorption and utilization. Because of these individual differences, a single diet will not suit everyone, so nutritional plans should consider each person’s biochemistry and relevant biomarkers. That’s why this statement is the best answer: it acknowledges that needs differ and there isn’t a universal diet. The other ideas don’t fit: there isn’t a universal diet for all, supplements aren’t always necessary or appropriate for everyone, and diet can and does influence disease risk.
