What are the essential nutrients for optimal human health?.

Essential nutrients are compounds that the body cannot synthesize and must be obtained through diet. These include macronutrients (proteins, fats, carbohydrates) and micronutrients (vitamins and minerals).

Key Facts

• Macronutrients: Provide energy; include carbohydrates (4 kcal/g), proteins (4 kcal/g), and fats (9 kcal/g).
• Micronutrients: Needed in smaller amounts; vitamins and minerals support various bodily functions.
• Essential Amino Acids: 9 amino acids must be obtained from food; they are vital for protein synthesis.
• Essential Fatty Acids: Omega-3 and omega-6 fatty acids are crucial for brain health and inflammation regulation.

Examples or Use Cases

Eating a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats helps ensure adequate intake of essential nutrients.
