Trying a healthier lifestyle begins with grasping the principles of nutrition. This guide explores the wide-ranging benefits of maintaining a balanced diet, defines the elements of healthy eating, and offers actionable tips to integrate better eating habits into your everyday life seamlessly.

What is a healthy diet?

A healthy diet provides the nutrition required for your body to function well while enhancing your overall health. According to the World Health Organization, a healthy diet can help prevent malnutrition and non-communicable diseases (NCDs) like diabetes, heart disease, stroke, and cancer.

Individual attributes (such as age, gender, lifestyle, and level of physical activity), cultural background, locally accessible foods, and dietary habits all influence the composition of a diversified, balanced, and nutritious diet.

What are the characteristics of a healthy diet?

An assortment of foods from the primary food groups

• Fresh fruits and vegetables full of vitamins and minerals;

• Whole grains like brown rice and whole wheat that provide the necessary fiber;

• Low-fat dairy products and lean proteins such as chicken, fish, and tofu which are essential for muscle and bone health;

• Legumes, nuts, and seeds that offer healthy fats and antioxidants.

Recommendations on portion sizes

Understanding how much to eat of each type of food is crucial for maintaining a healthy diet, as portion recommendations help manage calorie intake and ensure a balanced diet without overconsumption.

For instance, a serving of meat should be about the size of a deck of cards, while a portion of grains might be equivalent to a small cupped handful.

Foods that can be found in a local market

A healthy and practical diet comprises easy access to fresh and affordable foods, with locally sourced and seasonal products. This not only supports local economies but also reduces the environmental impact associated with long-distance food transport.

Suits your preferences, lifestyle, and budget

A practical diet plan is flexible and considers individual preferences, dietary restrictions, and lifestyle needs. Whether you are a busy professional needing quick, healthy meals or someone who enjoys cooking and experimenting with recipes, the diet should fit your economic situation and personal taste, ensuring that it is sustainable over the long term.

Reaping the benefits

A healthy diet has many benefits:

• May improve your longevity: Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins can extend life expectancy by reducing the risk of chronic diseases such as heart disease and cancer.

• Keeps skin, teeth, and eyes healthy: Vitamins A, C, and E, along with zinc and omega-3 fatty acids, enhance the health and function of skin, teeth, and eyes, protecting against environmental damage.

• Helps the muscles: Adequate protein intake ensures muscle repair and growth, and is necessary for recovery from daily activities and exercise.

• Improves immunity: Essential nutrients like vitamins C and E and minerals such as zinc and selenium boost the immune system’s ability to ward off illnesses.

• Fortifies the bones: Calcium and vitamin D are vital for maintaining bone strength and preventing density loss, indispensable as we age.

• Reduces the risk of chronic diseases: A diet low in saturated fats and high in fiber from various plant sources helps mitigate the risk of heart disease, type 2 diabetes, and certain cancers by improving blood cholesterol and sugar levels.

• Supports healthy pregnancies and breastfeeding: Key nutrients like folic acid, iron, calcium, and protein support fetal development and maternal health.

• Assists digestive function: High-fiber foods promote bowel health, preventing constipation and ensuring a healthy digestive tract.

• Helps achieve and maintain a healthy weight: Balanced calorie intake from a varied diet aids in maintaining a healthy body weight, thus reducing the risk of various health issues.

Foods to consume in moderation

Fats

In adults, limiting total fat consumption to less than 30% of total energy intake helps prevent harmful weight gain.

How to limit it?

• Instead of frying, cook by steaming or boiling;

• Use polyunsaturated fat-rich oils such as soybean, canola (rapeseed), corn, safflower, and sunflower oils instead of butter, lard, and ghee;

• Consume low-fat dairy products and lean meats, as well as cutting visible fat from meat;

• Reduce the ingestion of baked and fried food, and pre-packaged snacks and foods containing industrially processed trans-fats (doughnuts, cakes, pies, cookies, biscuits, and wafers).

Salt, sodium, and potassium

Most people consume too much sodium in the form of salt (an average of 9–12 g of salt per day) and too little potassium (less than 3.5 g). A diet high in sodium and low in potassium leads to high blood pressure, which raises the risk of heart disease and stroke. The recommended daily salt intake is less than 5 g.

How to limit it?

• When cooking and preparing dishes, use less salt and high-sodium condiments (such as soy sauce, fish sauce, and bouillon);

• Select products with less sodium;

• Remove salt and high-sodium sauces from your table;

• Restrict the consumption of salty snacks.

Sugars

Free sugar consumption should be kept to less than 10% of total energy intake in adults and children. Free sugar intake raises the risk of dental cavities, and excess calories from high-free-sugar foods and beverages promote harmful weight gain.

How to limit it?

• Sugary snacks, sweets, and sugar-sweetened beverages should be consumed in moderation;

• Instead of sugary snacks, eat fresh fruit and raw vegetables.

Sticking to a healthy eating pattern

It's always best to consult a nutritionist or doctor to determine the best approach for your case, but these tips can also help:

To get started, rely on professionals

Working with a qualified specialist can help you determine the best approach for you and guarantee that you receive valid, current information about healthy eating and how to sustain this habit.

Be kind to yourself

It takes time to form new habits, and healthy diets are no exception. When frustrated, practice self-kindness and focus again on your long-term goals. Your diet will likely continue moving in the right direction as long as you establish realistic expectations for yourself, stay dedicated, and reassess your progress.

Discover the best diet for you

Genetics, health, family, cultural traditions, work schedules, and other factors affect our lives differently. No single diet can fully account for so many individual components. The best healthy diet is the one that makes you feel good and that you can maintain over time.

Consume a whole-foods-based diet

Healthy diets take many forms, but most focus on nutritious, whole foods like fruits, vegetables, grains, and protein. They are full of fiber, phytonutrients, minerals, and vitamins, promote gut health, and decrease the risk of chronic diseases such as obesity and diabetes.

Enjoy your favorite foods

Denying yourself the foods you enjoy and crave can have unintended consequences. In the short term, it tends to intensify your cravings for such foods, particularly in people generally more prone to food cravings. Rather than renouncing your favorite less-nutritious foods, try eating them only sporadically and limiting your portions.

Don't take the "all-or-nothing" route

Instead of allowing all-or-nothing thinking to persuade you that anything other than perfection is a failure, think of each new diet decision you make as a fresh start. A single less-than-ideal decision does not have to lead to a day full of them.

Keep track of your progress

Self-monitoring is a simple and efficient method of keeping track of your progress. When tracking your progress, keep in mind that weight loss and gain aren't the sole indicators of your development, they might not be the optimal way to track progress in other circumstances, either.

People adhere to healthy eating habits for a variety of reasons. Instead of focusing on how much weight you've dropped, you can concentrate on how the dietary changes have affected your physical and mental health.
