Overview

Nutrients

Nutrients are substances required for human growth, maintenance, and activity. They are classified into energy-producing nutrients (carbohydrates, proteins, fats), micronutrients (vitamins, minerals), dietary fiber, and others. The Ministry of Health, Labour and Welfare's 'Dietary Reference Intakes for Japanese' establishes intake standards for each nutrient, and balanced dietary intake is fundamental to maintaining health.
