Key Takeaways
• A nutritious diet safeguards the body against malnutrition and helps prevent major noncommunicable diseases (NCDs) like diabetes, stroke, heart disease, and cancer.
• Poor eating habits combined with physical inactivity remain among the top global health risks today.
• Healthy eating starts early in life—breastfeeding supports strong growth, brain development, and long-term protection against obesity and chronic diseases.
• To maintain a healthy weight, your calorie intake should match your energy expenditure. Limit fats to 30% of total calories, with saturated fats under 10% and trans fats below 1%.
• Keep free sugars under 10% of your total calorie intake (preferably 5% for extra benefits).
• Salt intake should not exceed 5 grams daily (about one teaspoon) to lower the risk of high blood pressure, stroke, and heart disease.
Why a Healthy Diet Matters
Eating well throughout life reduces the risk of malnutrition and protects against lifestyle-related illnesses. However, modern diets are shifting due to urbanization and the widespread availability of processed foods. Many people now consume too much sugar, unhealthy fats, and sodium, while eating too few fruits, vegetables, and whole grains.
A healthy diet looks different for everyone depending on age, lifestyle, culture, and local food options—but the core principles remain the same.
What a Healthy Diet Includes (For Adults)
A balanced diet should feature:
• Plenty of fruits, vegetables, legumes, nuts, and whole grains.
• At least 400 grams (five servings) of fruits and vegetables daily (excluding starchy roots like potatoes and cassava).
• Less than 10% of daily calories from free sugars, ideally below 5%.
• Less than 30% of calories from fats, with a focus on unsaturated fats (found in fish, avocados, nuts, and plant oils like olive or sunflower oil).
• Fewer saturated and trans fats, which are commonly found in fatty meats, butter, and processed snacks.
• No more than 5 grams of salt daily—opt for iodized salt when possible.
Healthy Eating for Infants and Children
Proper nutrition during the first two years of life supports healthy development and lowers future disease risks.
• Babies should be exclusively breastfed for the first six months.
• Continue breastfeeding up to two years or longer, along with safe, nutrient-rich complementary foods.
• Avoid adding salt or sugar to baby food.
Practical Tips for a Healthier Diet
Fruits and Vegetables
• Include vegetables in every meal.
• Snack on fresh fruits or raw veggies.
• Choose seasonal produce.
• Mix up your selections for variety and color.
Fats
• Use boiling or steaming instead of frying.
• Replace butter or lard with plant-based oils (e.g., sunflower, canola, or soybean oil).
• Choose lean meats and low-fat dairy.
• Reduce intake of baked or fried snacks high in trans fats.
Salt and Sodium
Most people consume too much salt—often from processed foods like ready meals, meats, and sauces. Too much sodium increases blood pressure and the risk of heart disease.
To cut back:
• Limit salt in cooking and on the table.
• Choose low-sodium versions of your favorite products.
• Replace salty snacks with fresh fruit or nuts.
Increasing potassium intake through fruits and vegetables can help balance sodium’s effects.
Sugar
Too much sugar increases the risk of tooth decay, weight gain, and heart disease.
To reduce sugar:
• Avoid sugary drinks and sweetened snacks.
• Drink water or herbal tea instead.
• Snack on fresh fruit rather than candy or desserts.
Encouraging Healthy Eating Habits
Our diets are shaped by many influences—economic status, food prices, culture, and lifestyle. Governments, businesses, and individuals all play a role in creating healthier food environments.
Key public actions include:
• Supporting farmers and retailers who provide fresh produce.
• Reducing the marketing and production of high-fat, high-sugar foods.
• Enforcing nutrition labeling for transparency.
• Promoting healthy school meals and public awareness campaigns.
• Encouraging nutrition education for children and families.
The Global Effort
The World Health Organization (WHO) leads global efforts to promote nutrition and fight obesity. Its initiatives include:
• The Global Strategy on Diet and Physical Activity (2004).
• Nutrition plans for mothers and children (2012).
• The Global Action Plan for Noncommunicable Diseases (2013–2020).
• Programs to reduce salt intake and eliminate industrial trans fats from the global food supply.
Through these initiatives, WHO and its partners aim to ensure healthier lives and well-being for everyone, at every age.
Final Thoughts
A healthy diet is not about restriction—it’s about balance, variety, and moderation. By making mindful food choices and supporting policies that promote nutritious options, individuals and societies alike can take a powerful step toward a healthier, longer, and more energetic life.
