A healthy diet emphasizes consuming a variety of fruits, vegetables, whole grains, lean protein, and healthy fats while limiting saturated and trans fats, added sugars, and sodium. Focusing on whole, unprocessed foods and prioritizing these food groups can help you achieve a balanced and nutritious diet. 

Key Components of a Healthy Diet:

• Fruits and Vegetables:These are packed with vitamins, minerals, and fiber, offering numerous health benefits. Aim for at least five servings daily. 
• Whole Grains:Choose whole grains like brown rice, quinoa, and whole-wheat bread over refined grains. They provide more fiber and nutrients than refined grains. 
• Lean Protein:Include lean meats, poultry, fish, beans, and nuts for a good source of protein and other essential nutrients. 
• Healthy Fats:Incorporate unsaturated fats from sources like olive oil, nuts, and avocados. 
• Dairy (or Alternatives):Choose low-fat or fat-free dairy products like milk and yogurt, or explore plant-based alternatives. 

Foods to Limit or Avoid: 

• Saturated and Trans Fats: These fats are found in fatty meats, full-fat dairy products, and some processed foods. 
• Added Sugars: Limit sugary drinks and foods that contain added sugars. 
• Sodium: Reduce sodium intake to less than 2,300 milligrams per day, ideally 1,500 mg. 
• Ultra-processed Foods: These foods are heavily processed and may lack essential nutrients. 

Additional Tips for Healthy Eating:

• Eat a variety of foods: This ensures you get a wide range of nutrients. 
• Read food labels: Pay attention to the serving size, calories, and nutritional information. 
• Drink plenty of water: Staying hydrated is crucial for overall health. 
• Plan your meals: This can help you make healthier choices and avoid impulsive snacking. 
• Be mindful of portion sizes: Control your portions to avoid overeating. 
• Get regular physical activity: Combine a healthy diet with regular exercise for optimal health.

Key facts

• A healthy diet helps to protect against malnutrition in all its forms, as well as noncommunicable diseases (NCDs), including diabetes, heart disease, stroke and cancer.
• Unhealthy diet and lack of physical activity are leading global risks to health.
• Healthy dietary practices start early in life – breastfeeding fosters healthy growth and improves cognitive development, and may have longer term health benefits such as reducing the risk of becoming overweight or obese and developing NCDs later in life.
• Energy intake (calories) should be in balance with energy expenditure. To avoid unhealthy weight gain, total fat should not exceed 30% of total energy intake (1, 2, 3). Intake of saturated fats should be less than 10% of total energy intake, and intake of trans-fats less than 1% of total energy intake, with a shift in fat consumption away from saturated fats and trans-fats to unsaturated fats (3), and towards the goal of eliminating industrially-produced trans-fats (4, 5, 6).
• Limiting intake of free sugars to less than 10% of total energy intake (2, 7) is part of a healthy diet. A further reduction to less than 5% of total energy intake is suggested for additional health benefits (7).
• Keeping salt intake to less than 5 g per day (equivalent to sodium intake of less than 2 g per day) helps to prevent hypertension, and reduces the risk of heart disease and stroke in the adult population (8).
• WHO Member States have agreed to reduce the global population’s intake of salt by 30% by 2025; they have also agreed to halt the rise in diabetes and obesity in adults and adolescents as well as in childhood overweight by 2025 (9, 10).

Overview

Consuming a healthy diet throughout the life-course helps to prevent malnutrition in all its forms as well as a range of noncommunicable diseases (NCDs) and conditions. However, increased production of processed foods, rapid urbanization and changing lifestyles have led to a shift in dietary patterns. People are now consuming more foods high in energy, fats, free sugars and salt/sodium, and many people do not eat enough fruit, vegetables and other dietary fibre such as whole grains.

The exact make-up of a diversified, balanced and healthy diet will vary depending on individual characteristics (e.g. age, gender, lifestyle and degree of physical activity), cultural context, locally available foods and dietary customs. However, the basic principles of what constitutes a healthy diet remain the same.

For adults

A healthy diet includes the following:

• Fruit, vegetables, legumes (e.g. lentils and beans), nuts and whole grains (e.g. unprocessed maize, millet, oats, wheat and brown rice).
• At least 400 g (i.e. five portions) of fruit and vegetables per day (2), excluding potatoes, sweet potatoes, cassava and other starchy roots.
• Less than 10% of total energy intake from free sugars (2, 7), which is equivalent to 50 g (or about 12 level teaspoons) for a person of healthy body weight consuming about 2000 calories per day, but ideally is less than 5% of total energy intake for additional health benefits (7). Free sugars are all sugars added to foods or drinks by the manufacturer, cook or consumer, as well as sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
• Less than 30% of total energy intake from fats (1, 2, 3). Unsaturated fats (found in fish, avocado and nuts, and in sunflower, soybean, canola and olive oils) are preferable to saturated fats (found in fatty meat, butter, palm and coconut oil, cream, cheese, ghee and lard) and trans-fats of all kinds, including both industrially-produced trans-fats (found in baked and fried foods, and pre-packaged snacks and foods, such as frozen pizza, pies, cookies, biscuits, wafers, and cooking oils and spreads) and ruminant trans-fats (found in meat and dairy foods from ruminant animals, such as cows, sheep, goats and camels). It is suggested that the intake of saturated fats be reduced to less than 10% of total energy intake and trans-fats to less than 1% of total energy intake (5). In particular, industrially-produced trans-fats are not part of a healthy diet and should be avoided (4, 6).
• Less than 5  g of salt (equivalent to about one teaspoon) per day (8).  Salt should be iodized.

For infants and young children

In the first 2 years of a child’s life, optimal nutrition fosters healthy growth and improves cognitive development. It also reduces the risk of becoming overweight or obese and developing NCDs later in life.

Advice on a healthy diet for infants and children is similar to that for adults, but the following elements are also important:

• Infants should be breastfed exclusively during the first 6 months of life.
• Infants should be breastfed continuously until 2 years of age and beyond.
• From 6 months of age, breast milk should be complemented with a variety of adequate, safe and nutrient-dense foods. Salt and sugars should not be added to complementary foods.

Practical advice on maintaining a healthy diet

Fruit and vegetables

Eating at least 400 g, or five portions, of fruit and vegetables per day reduces the risk of NCDs (2) and helps to ensure an adequate daily intake of dietary fibre.

Fruit and vegetable intake can be improved by:

• always including vegetables in meals;
• eating fresh fruit and raw vegetables as snacks;
• eating fresh fruit and vegetables that are in season; and
• eating a variety of fruit and vegetables.

WHO response

The “WHO Global Strategy on Diet, Physical Activity and Health” (14) was adopted in 2004 by the Health Assembly. The strategy called on governments, WHO, international partners, the private sector and civil society to take action at global, regional and local levels to support healthy diets and physical activity.

In 2010, the Health Assembly endorsed a set of recommendations on the marketing of foods and non-alcoholic beverages to children (15). These recommendations guide countries in designing new policies and improving existing ones to reduce the impact on children of the marketing of foods and non-alcoholic beverages to children. WHO has also developed region-specific tools (such as regional nutrient profile models) that countries can use to implement the marketing recommendations.

In 2012, the Health Assembly adopted a “Comprehensive Implementation Plan on Maternal, Infant and Young Child Nutrition” and six global nutrition targets to be achieved by 2025, including the reduction of stunting, wasting and overweight in children, the improvement of breastfeeding, and the reduction of anaemia and low birthweight (9).

In 2013, the Health Assembly agreed to nine global voluntary targets for the prevention and control of NCDs. These targets include a halt to the rise in diabetes and obesity, and a 30% relative reduction in the intake of salt by 2025. The “Global Action Plan for the Prevention and Control of Noncommunicable Diseases 2013–2020” (10) provides guidance and policy options for Member States, WHO and other United Nations agencies to achieve the targets.

8 tips for healthy eating

These 8 practical tips cover the basics of healthy eating and can help you make healthier choices.

The key to a healthy diet is to eat the right amount of calories for how active you are so you balance the energy you consume with the energy you use.

If you eat or drink more than your body needs, you’ll put on weight because the energy you do not use is stored as fat. If you eat and drink too little, you’ll lose weight.

You should also eat a wide range of foods to make sure you’re getting a balanced diet and your body is receiving all the nutrients it needs.

It’s recommended that men have around 2,500 calories a day (10,500 kilojoules). Women should have around 2,000 calories a day (8,400 kilojoules).

Most adults in the UK are eating more calories than they need and should eat fewer calories.

Eating a balanced diet

Eating a healthy, balanced diet is an important part of maintaining good health, and can help you feel your best.

This means eating a wide variety of foods in the right proportions, and consuming the right amount of food and drink to achieve and maintain a healthy body weight.
