Food Gives Us Energy (Beginner Intermediate)
Paragraph 1: Food Gives Us Energy
Every day, our bodies need good food to stay alive, walk, work, and think. When we eat, our system breaks down meals to create fuel. This natural process is called metabolism. Scientists put our main foods into three big groups called macronutrients: carbohydrates, proteins, and fats. Eating the right mix gives us strength and keeps our organs safe. Over the centuries, doctors **have studied** how different meals change human energy. Today, we know that good choices lead to a happy life.
Vocabulary: alive, breaks down, fuel, process, metabolism, strength, organs.
Grammar Question: In the sentence *”doctors have studied how different meals change human energy,”* what helping verb connects to the past participle *studied*?
Paragraph 2: Carbohydrates for Fast Fuel
Carbohydrates are foods like bread, rice, fruit, and potatoes. Inside your stomach, these foods turn into simple sugar called glucose. Glucose enters your blood quickly to give power to your muscles and brain. However, eating too many sweet snacks can make your blood sugar jump too high. Many people **have chosen** to cut down on white sugar to avoid feeling tired after meals. Learning to pick healthy, slow-burning grains helps your body keep a steady level of daily power.
Vocabulary: carbohydrates, simple, glucose, power, snacks, avoid, steady.
Grammar Question: Which irregular past participle follows the verb *have* in the sentence about cutting down on sugar?
Paragraph 3: Proteins to Build and Repair
Protein is the building block for the human frame. You find it in eggs, fish, cheese, beans, and seeds. When your metabolism uses protein, it breaks the food into tiny parts named amino acids. Your body uses these small pieces like bricks to build strong muscles, repair cuts, and make new skin. Active athletes **have used** extra protein shakes to grow bigger muscles after hard exercise. Even if you only walk every day, your body needs fresh protein to fix its tissues while you sleep.
Vocabulary: building block, frame, pieces, repair, cuts, tissues, exercise.
Grammar Question: What is the subject that performs the action in the sentence *”Active athletes have used extra protein shakes”*?
Paragraph 4: Fats for Long-Term Protection
Healthy fats are very important for long-term health. Foods like olive oil, avocados, butter, and nuts provide clean, slow-burning fuel. Unlike quick sugars, fat gives you energy that lasts for many hours without hunger. Fats also protect your vital organs, keep you warm in cold weather, and help your brain send messages across your nerves. In recent years, researchers **have discovered** that natural fats do not make you sick if you avoid eating them with lots of refined sugar.
Vocabulary: important, provide, hunger, vital, weather, nerves, discovered, refined.
Grammar Question: Does the phrase *”researchers have discovered”* describe an event that finished in the past with importance for our knowledge right now?
Paragraph 5: Balancing Your Daily Meals
Metabolism works best when all three macronutrients work together in balance. Your body needs fuel to run, materials to fix damage, and healthy fats to protect your nervous system. Many people feel confused by television diets, but simple cooking at home is often best. Millions of families **have changed** their habits by eating fresh whole foods instead of boxed meals. When you listen to your body, healthy eating becomes an easy, joyful habit every single day.
Vocabulary: balance, materials, damage, nervous system, confused, habits, joyful.
Grammar Question: In the sentence *”Millions of families have changed their habits,”* why do we use *have* instead of *has*?
