1. Understanding Basic Nutrition: The Abcs Of Nutrition Worksheet Answers
Nutrition is the science of nutrients and their impact on the body. Essential nutrients are substances that the body cannot produce on its own and must obtain from food. They include carbohydrates, protein, fats, vitamins, and minerals. A balanced diet provides all the essential nutrients in the right proportions for optimal health.
Healthy food choices include fruits, vegetables, whole grains, lean protein, and low-fat dairy products. These foods are rich in nutrients and low in calories, saturated fat, and sodium.
2. Macronutrients
Carbohydrates, Protein, and Fats
Carbohydrates
Carbohydrates provide the body with energy. They are classified into simple carbohydrates (sugars) and complex carbohydrates (starches and fiber). Complex carbohydrates are digested more slowly and provide a more sustained source of energy.
Protein
Protein is essential for building and repairing tissues. It is also involved in hormone production and immune function. Complete proteins contain all nine essential amino acids, while incomplete proteins lack one or more.
Fats
Fats provide energy and support cell function. They are classified into saturated fats (solid at room temperature), unsaturated fats (liquid at room temperature), and trans fats (artificially created). Unsaturated fats are healthier than saturated fats, while trans fats should be avoided.

|---|---|---|
| Karbohidrat | Energi | Roti, pasta, nasi, buah-buahan, sayuran |
| Protein | Membangun dan memperbaiki jaringan | Daging, ikan, telur, kacang-kacangan, biji-bijian |
