The Core Principles of Healthy Eating
Healthy eating is founded on balance, variety, and moderation. While individual dietary needs can vary, the core principles of a healthy diet are consistent globally, emphasizing fresh, whole foods and limiting processed items.
Prioritizing Plant-Based Foods
A diet rich in fruits, vegetables, and plant-based proteins is key for essential vitamins, minerals, fiber, and antioxidants.
- Fruits and Vegetables: Aim for at least 400g (five portions) daily, including a variety of types and colors, to help reduce the risk of noncommunicable diseases.
- Whole Grains: Choose whole grains like oats and brown rice over refined options for more fiber and improved digestion.
- Legumes, Nuts, and Seeds: Incorporate these sources for plant-based protein, fiber, and healthy fats.
Choosing Healthy Protein Sources
Protein is important for various bodily functions. Opt for healthier protein sources.
- Lean Meats and Poultry: Select lean cuts and skinless poultry, and consume red meat in moderation.
- Fish: Include at least two fish portions weekly, with oily fish providing beneficial omega-3 fatty acids.
- Dairy or Alternatives: Choose lower-fat and lower-sugar dairy or select fortified plant-based options for calcium.
Managing Fats, Sugars, and Salt
Limiting unhealthy fats, sugars, and salt is vital for preventing health issues.
- Fats: Total fat intake should be less than 30% of daily energy, favoring unsaturated fats and avoiding industrially produced trans fats.
- Sugars: Limit free sugars to less than 10% of total energy, ideally below 5% for greater benefits. This includes added sugars and those in honey and juice.
- Salt: Keep daily salt intake under 5 grams to manage blood pressure. Be mindful of salt in processed foods.
