Balancing Energy Intake and Expenditure

To maintain a healthy weight and prevent excessive weight gain, it is essential to balance energy intake (calories consumed) with energy expenditure (calories burned). The total fat intake should not exceed 30% of the total energy intake, with saturated fats comprising less than 10% and trans-fats less than 1% of the total energy intake. Instead, the focus should shift towards consuming unsaturated fats and eliminating industrially-produced trans-fats. Additionally, limiting the intake of free sugars to less than 10% of total energy intake is recommended, with further reduction for additional health benefits. Salt intake should be kept below 5 grams per day to prevent hypertension, heart disease, and stroke.

Nutrition and Nutrition Types


Essential Components of a Healthy Diet

A healthy diet should include a variety of nutrient-dense foods that provide the necessary vitamins, minerals, and other beneficial compounds. The composition of a diversified and balanced diet may vary based on individual characteristics, cultural context, and local food availability. Here are the key elements of a healthy diet for adults:


  1. Fruit, Vegetables, Legumes, and Whole Grains

Including ample amounts of fruits, vegetables, legumes, and whole grains is crucial for a nutritious diet. Aim for at least 400 grams or five portions of fruits and vegetables daily, excluding starchy roots. These natural, unprocessed foods provide essential vitamins, minerals, dietary fiber, and antioxidants that promote overall health.


  1. Healthy Fats

Opt for unsaturated fats in fish, avocados, nuts, and oils like sunflower, soybean, canola, and olive oil. Saturated fats, present in fatty meats, butter, palm and coconut oil, cream, cheese, and lard, should be limited to less than 10% of total energy intake. Trans-fats, including industrially-produced and ruminant trans-fats, should be avoided entirely.


  1. Controlled Salt Intake

Keep daily salt consumption below 5 grams (approximately one teaspoon) to reduce the risk of hypertension, heart disease, and stroke. Opt for iodized salt, and be mindful of hidden salt in processed foods and condiments. Fresh herbs and spices can be used as flavorful alternatives.


Promoting Healthy Eating Habits

Encouraging healthy eating habits is crucial in promoting overall well-being. Here are some practical tips to incorporate into your daily routine:


  1. Fruit and Vegetable Consumption

Make it a habit to include vegetables in every meal. Snack on fresh fruits and raw vegetables, choose seasonal produce and diversify your choices to ensure a wide range of nutrients.


  1. Cooking Methods and Fat Choices

Prefer steaming or boiling over frying when preparing meals. Replace saturated fats with unsaturated fats by using oils rich in polyunsaturated fats like soybean, canola, corn, safflower, or olive oil. Avoid using excessive amounts of oil and opt for lean cooking techniques like grilling or baking.


  1. Limit Processed Foods and Added Sugars

Processed foods often contain high levels of unhealthy fats, added sugars, and salt. Limit your consumption of processed snacks, sugary drinks, and desserts. Opt for whole foods and homemade meals as much as possible, as they provide more nutrients and fewer additives.


  1. Portion Control

Practice portion control to avoid overeating. Be mindful of serving sizes and listen to your body’s hunger and fullness cues. Avoid eating large portions in one sitting and consider using smaller plates and bowls to help with portion control.


  1. Stay Hydrated

Drink an adequate amount of water throughout the day to stay hydrated. Water is essential for various bodily functions and can help control appetite. Limit the consumption of sugary beverages like sodas, energy drinks, and fruit juices, as they are high in added sugars and calories.


  1. Plan and Prepare Meals

Planning and preparing meals in advance can help you make healthier choices and avoid relying on fast food or processed meals. Create a weekly meal plan, make a grocery list, and prioritize whole, unprocessed ingredients. This practice can save you time and money while promoting a healthier lifestyle.


  1. Mindful Eating

Practice mindful eating by paying attention to your food, savoring each bite, and eating slowly. This allows you to enjoy your meals and recognize when you’re satisfied, reducing the chances of overeating. Avoid distractions like screens or work while eating, which can lead to mindless consumption.
