Principles of a Balanced Diet - High School Unit

Healthy nutrition is about much more than counting calories. A balanced diet requires the right combination of energy intake, macronutrients, micronutrients, metabolism, and evidence-based meal planning that adapts to individual needs and lifestyles. This comprehensive instructional unit helps students understand the biological foundations of nutrition through engaging investigations and authentic real-world applications.

Designed for Grades 9–12, this resource integrates Biology, Human Physiology, Nutrition, and Health Science while promoting scientific literacy, inquiry-based learning, and evidence-based decision-making.

Product Description

Students begin by exploring the core principles of healthy nutrition, investigating energy requirements, nutrient balance, dietary diversity, and evidence-based dietary recommendations.

The unit then examines carbohydrates, fats, proteins, vitamins, and minerals, explaining how each nutrient supports metabolism, growth, immune function, cellular activity, and overall human health.

Students investigate energy balance by calculating Basal Metabolic Rate (BMR), Total Energy Expenditure, and Physical Activity Level (PAL), allowing them to understand how nutritional needs differ depending on age, activity level, and lifestyle.

A major focus of the curriculum is practical meal planning. Students apply the Plate Method to design balanced meals, compare dietary patterns, evaluate nutritional quality, and solve authentic health scenarios using scientific evidence.

Modern scientific diagrams, comparison charts, inquiry-based investigations, differentiated classroom activities, nutrition planning exercises, assessments, and complete answer keys make this resource ideal for rigorous secondary science instruction.
