A balanced diet is essential for optimal health, providing the body with the right mix of nutrients to support energy, growth, and disease prevention. It emphasizes variety, moderation, and nutrient-dense foods from all major food groups.
Key Components:
Fruits and Vegetables: Aim for at least 5 servings daily. These provide vitamins, minerals, fiber, and antioxidants. Examples include apples, broccoli, spinach, and berries for immune support and digestion.
Grains: Choose whole grains like oats, brown rice, and quinoa for half of your grain intake. They offer complex carbohydrates for sustained energy and fiber to regulate blood sugar.
Proteins: Include 2-3 servings of lean sources such as chicken, fish, beans, nuts, or tofu. Proteins aid in muscle repair and hormone production; opt for fatty fish like salmon for omega-3s.
Dairy or Alternatives: Consume 2-3 servings of low-fat milk, yogurt, cheese, or plant-based options like almond milk. These supply calcium and vitamin D for bone health.
Fats: Limit to healthy sources like avocados, olive oil, and seeds. Fats are vital for brain function and cell growth, but keep saturated fats low.
Daily Guidelines:
– Calories: Tailor to age, gender, and activity level (e.g., 2,000 for adults), with 45-65% from carbs, 10-35% from proteins, and 20-35% from fats.
– Hydration: Drink at least 8 glasses of water daily.
– Balance: Fill half your plate with fruits and veggies, a quarter with grains, and a quarter with proteins.
