The Core Principle: Understanding 'Per 100g'
For anyone committed to a mindful and nutritious diet, reading food labels is an essential skill. While many labels display nutritional information 'per serving', this figure can often be misleading as serving sizes are determined by manufacturers and can vary wildly between similar products. This is where the 'per 100g' column becomes your most powerful tool. It provides a universal benchmark, giving you an accurate, like-for-like comparison of the nutrient density of any food product, whether it's a solid food measured in grams or a liquid measured per 100ml. By standardizing the unit of measurement, it effectively levels the playing field, allowing you to cut through marketing claims and make truly informed decisions about what you consume. This is the foundation of smart, strategic grocery shopping for better nutrition.
Demystifying the Nutrition Information Panel
The nutrition information panel, or NIP, is a treasure trove of data, and the 'per 100g' column is the key to unlocking its secrets. Here is a breakdown of what you'll find and how to interpret it for every 100 grams of the product:
- Energy (Calories/Kilojoules): This figure tells you the total energy content of the food. By comparing the 'per 100g' energy value of different brands, you can easily identify the most calorie-dense options.
- Protein: Essential for muscle repair and growth, a higher protein value per 100g indicates a more protein-rich food.
- Total Fat and Saturated Fat: This tells you the total fat content, with a separate line for saturated fat, the type that should be limited for heart health.
- Carbohydrates and Sugars: Carbs are an energy source, but the sugars sub-category is crucial. The 'per 100g' value helps you identify foods with high levels of natural or added sugars.
- Sodium (Salt): High sodium intake is linked to health issues like high blood pressure. The 'per 100g' measurement makes it simple to find lower-salt options.
- Dietary Fibre: Often a marker of a healthier food choice, fibre can be compared effectively using the 'per 100g' metric to select high-fibre options.
High, Medium, or Low: Using 'Per 100g' Benchmarks
To put these numbers into perspective, health authorities provide clear benchmarks for what is considered high, medium, and low for certain nutrients based on the 'per 100g' value. By keeping these in mind, you can quickly assess a product's nutritional profile.
| Nutrient | High (Per 100g) | Low (Per 100g) |
|---|---|---|
| Total Fat | More than 17.5g | 3g or less |
| Saturated Fat | More than 5g | 1.5g or less |
| Sugars | More than 22.5g | 5g or less |
| Salt | More than 1.5g (or 0.6g sodium) | 0.3g or less (or 0.1g sodium) |
Per 100g vs. Per Serving: A Clear Comparison
While 'per 100g' is the gold standard for comparison, 'per serving' has its uses. Here's a table to help you understand when to use each measurement:
| Feature | 'Per 100g' | 'Per Serving' |
|---|---|---|
| Standardization | High—Creates a level playing field for all products. | Low—Serving sizes can be inconsistent and arbitrary. |
| Best Use Case | Comparing different brands of similar products (e.g., cereals, yogurts). | Estimating the nutrients in the exact amount you plan to consume. |
| Risk of Misinformation | Low—Offers an objective, percentage-based view. | High—Small serving sizes can make a product appear healthier than it is. |
| Dietary Tracking | Ideal for comparing nutrient density and making long-term dietary shifts. | Useful for tracking daily intake based on the manufacturer's suggestion. |
A Step-by-Step Guide to Using 'Per 100g'
Incorporating the 'per 100g' information into your shopping routine is a simple process that yields significant nutritional benefits:
- Select Your Products: Grab two or more similar products you wish to compare, such as two different brands of muesli or two types of canned soup.
- Locate the Nutrition Panel: Find the Nutrition Information Panel, usually on the back or side of the packaging.
- Focus on the 'Per 100g' Column: Ignore the 'per serving' column for now and direct your attention to the 'per 100g' values.
- Compare Key Nutrients: Look at the figures for saturated fat, sugar, and sodium. Use the benchmarks provided earlier to quickly assess if the product is high, medium, or low in these areas.
- Look for Favourable Traits: Compare other important metrics like protein and fibre. A higher value per 100g in these categories generally indicates a more nutrient-dense product.
- Make Your Informed Choice: Based on this side-by-side comparison, you can confidently choose the product that best aligns with your dietary goals.
Conclusion: Making Smarter Dietary Choices
The 'per 100g' measurement is a powerful and reliable tool for anyone looking to make healthier, more informed dietary decisions. It offers a clear, objective standard for comparing products, bypassing potentially misleading serving size claims. By focusing on this metric, you can easily identify nutrient-dense foods, steer clear of those high in unhealthy fats, sugar, and salt, and take control of your nutrition. Using this simple approach transforms you from a passive consumer into an active participant in your health, ensuring your shopping cart is filled with choices that truly benefit your diet.

The Power of the 'Per 100g' Metric in Your Nutrition Diet
Understanding the 'per 100g' value on food labels is crucial for making informed choices. It allows you to objectively compare similar products, evaluate their nutrient density, and avoid misleading serving size tactics from manufacturers. By focusing on this standardized figure, you can more accurately track your intake of fats, sugars, and salt, aligning your purchases with your health goals. This simple practice helps you prioritize whole, nutrient-dense foods over those high in less desirable components. Ultimately, using the 'per 100g' column empowers you to take control of your diet and build healthier eating habits. This simple yet effective strategy can lead to significant improvements in your overall nutrition.
