NES Elementary Education (102/103) Practice Test

Living a healthy lifestyle is built on three practical habits: staying adequately hydrated, eating a balanced mix of nutrients, and engaging in regular physical activity. Water supports hydration, digestion, temperature control, and overall bodily functions, while good nutrition provides the vitamins, minerals, and energy the body needs to grow, repair, and stay focused. Regular exercise strengthens the heart and muscles, helps maintain a healthy weight, boosts mood, and increases energy for daily activities. Together, these components help you feel your best and support long-term health. The other options don’t fit because a high-sugar diet can harm health, a sedentary lifestyle reduces fitness and raises risk, and avoiding all fats deprives the body of essential nutrients needed for energy and brain function.
