How to Read Nutrition Labels: A Practical Guide

Learn how to read and understand nutrition labels. Make smarter food choices by decoding calories, macros, ingredients, and health claims.

Why Nutrition Labels Matter

Nutrition labels help you compare foods, control portions, and make healthier choices. Understanding them is key to managing weight, health, and fitness goals.

Key Information on Labels

  • Serving size
  • Calories per serving
  • Macronutrients: protein, carbs, fat
  • Sugar, fiber, sodium
  • Ingredients list
  • Allergens

Serving Size and Calories

Always check the serving size—many packages contain more than one. Calories are listed per serving, not per package.

Example Serving Size Calories
Granola bar 1 bar (35g) 140
Cereal 1 cup (40g) 160

Macronutrients

  • Protein: supports muscle and satiety
  • Carbohydrates: energy, includes sugar and fiber
  • Fat: energy, includes saturated and unsaturated

Ingredients List

Ingredients are listed by weight, from most to least. Shorter lists with recognizable foods are usually healthier.

Health Claims and Marketing

  • "Low fat" or "sugar free" doesn’t always mean healthy
  • Look for added sugars, sodium, and artificial ingredients
  • Ignore front-of-package marketing—read the label!

Key Takeaway

Čítanie etikiet ti pomôže robiť lepšie rozhodnutia v obchode aj v kuchyni. Porovnávaj produkty a sleduj hlavne zloženie, nie len kalórie.
