About nutritionFood nutrition is the study of how different components of food support the body’s energy needs, growth, and daily functioning. All foods provide energy measured in kilocalories (kcal), which come from three main macronutrients: carbohydrates, proteins, and fats. Carbohydrates are the body’s primary energy source and include starches and sugars, while proteins are essential for tissue repair, enzyme production, and immune function. Fats are the most energy-dense nutrient, supplying more than twice the calories per gram compared to carbohydrates and proteins, and they play a crucial role in hormone production and nutrient absorption.In addition to macronutrients, food contains micronutrients such as vitamins and minerals, which are required in smaller amounts but are vital for metabolic processes, bone health, nerve function, and overall well-being. Sugars are a subset of carbohydrates and can occur naturally, as in fruits and milk, or be added during food processing. Dietary fiber, another type of carbohydrate, does not provide calories but supports digestion, gut health, and blood sugar regulation. Understanding the balance between total carbohydrates, sugars, and fiber is essential for managing energy levels and long-term health. Nutrition labels are designed to help consumers evaluate food quality by listing energy value, macronutrients, and sometimes micronutrients per serving or per 100 grams. Interpreting these labels correctly is key, as serving sizes can vary and may influence how calorie content appears. A basic understanding of food nutrition allows individuals to compare products accurately, make informed dietary choices, and maintain a balanced intake that supports both health and lifestyle needs. nutrition how to
