Macronutrients

Carbohydrates

• Types:
  • Simple Carbohydrates: These are sugars that provide quick energy. Found in fruits (fructose), table sugar (sucrose), and dairy (lactose).
  • Complex Carbohydrates: These include starches and fibers found in whole grains, legumes, and vegetables. They take longer to digest, providing sustained energy.
• Function: Carbohydrates are the body's primary energy source. They are broken down into glucose, which fuels cells, tissues, and organs.
• Fiber: A type of carbohydrate that the body can’t digest. Important for digestive health, regulating blood sugar, and lowering cholesterol.

2. Proteins

• Structure: Made up of amino acids, which are the building blocks of the body. There are 20 amino acids, 9 of which are essential and must be obtained through diet.
• Sources:
  • Animal Sources: Meat, fish, poultry, eggs, and dairy.
  • Plant Sources: Beans, lentils, tofu, nuts, and seeds.
• Function: Essential for growth, repair, and maintenance of body tissues. Proteins also play a role in enzyme and hormone production, immune function, and muscle contraction.

3. Fats

• Types:
  • Saturated Fats: Typically solid at room temperature, found in animal products (like butter and cheese) and some plant oils (like coconut oil). Should be consumed in moderation.
  • Unsaturated Fats: Usually liquid at room temperature, considered healthier. They can be further categorized into:
    • Monounsaturated Fats: Found in olive oil, avocados, and nuts. Help improve heart health.
    • Polyunsaturated Fats: Include omega-3 and omega-6 fatty acids, found in fatty fish, flaxseeds, and walnuts. Important for brain health and inflammation reduction.
• Trans Fats: Artificially created fats found in some processed foods. These should be avoided due to their negative health effects.
• Function: Fats provide a concentrated source of energy, aid in the absorption of fat-soluble vitamins (A, D, E, K), and are essential for cell membrane structure and hormone production.

Recommended Daily Intake

• Carbohydrates: 45-65% of total daily calories.
• Proteins: 10-35% of total daily calories.
• Fats: 20-35% of total daily calories.

Key Takeaways

• Balancing these macronutrients is essential for optimal health and energy levels.
• Focus on whole food sources for all macronutrients, as they provide additional vitamins, minerals, and fiber.
• Individual needs may vary based on factors like age, sex, activity level, and health goals.
