Learn about the essential nutrients and how they impact your health

Understanding Calories
Calories are units of energy that fuel your body's functions. They power everything from breathing and thinking to running and exercising. The number of calories you need depends on your age, gender, weight, height, and activity level.
Daily Guidelines: Adult women typically need 1,800-2,400 calories, while adult men need 2,200-3,000 calories. However, individual needs vary. Consuming too many calories leads to weight gain, while too few can cause fatigue and nutritional deficiencies.

The Power of Protein
Protein is essential for building and repairing tissues, making enzymes and hormones, and supporting immune function. It's made up of amino acids, often called the "building blocks of life." Your body needs 20 different amino acids, nine of which are essential and must come from food.
Recommended Intake: Adults should consume 0.8g of protein per kilogram of body weight daily. Athletes and active individuals may need 1.2-2.0g/kg. Good sources include lean meats, fish, eggs, dairy, legumes, nuts, and seeds.

Carbohydrates: Your Body's Fuel
Carbohydrates are your body's primary energy source. They break down into glucose, which fuels your brain, muscles, and organs. There are two types: simple carbs (sugars) that provide quick energy, and complex carbs (starches and fiber) that provide sustained energy.
Smart Choices: Focus on complex carbs from whole grains, vegetables, and fruits. These provide fiber, vitamins, and minerals. Limit refined carbs and added sugars, which spike blood sugar and provide empty calories. Aim for 45-65% of daily calories from carbs.

Essential Fats for Health
Dietary fats are crucial for absorbing vitamins A, D, E, and K, protecting organs, and supporting cell growth. Not all fats are equal: unsaturated fats (found in olive oil, nuts, avocados, and fish) are heart-healthy, while saturated and trans fats should be limited.
Optimal Intake: Fats should comprise 20-35% of daily calories. Prioritize omega-3 fatty acids from fatty fish, which reduce inflammation and support brain health. Limit saturated fats to less than 10% of calories and avoid trans fats entirely.

The Truth About Sugars
Sugars are simple carbohydrates that occur naturally in fruits, vegetables, and dairy (natural sugars) or are added during processing (added sugars). While natural sugars come with fiber, vitamins, and minerals, added sugars provide only empty calories and can harm health.
Recommendations: The American Heart Association recommends limiting added sugars to 25g (6 teaspoons) for women and 36g (9 teaspoons) for men daily. Excess sugar consumption is linked to obesity, type 2 diabetes, heart disease, and tooth decay. Read labels carefully!

Creating a Balanced Diet
A balanced diet includes the right proportions of macronutrients (protein, carbs, fats) and micronutrients (vitamins, minerals). It's not about restriction but about making informed choices. Use tools like NutriLookup to track nutrition and ensure you're meeting your body's needs.
Practical Tips: Fill half your plate with vegetables and fruits, a quarter with lean protein, and a quarter with whole grains. Stay hydrated, limit processed foods, and practice portion control. Remember, sustainable healthy eating is about progress, not perfection!
