%DI Labelling - what does it mean?

%DI Labelling - what does it mean?
No video selected.

If you're into healthy eating then you probably check out food packs for nutrition information. It isn't always clear is it? You may have spotted the %DI on the labels but do you know how to interpret this for you or your children?  The food industry believes many consumers are confused by labelling and has come up with a graphic way of presenting the figures on the front of the pack but I'm not sure it will be all that helpful.

What is %DI labelling?

%DI stands for Percentage of Daily Intake. The Daily Intake Guides look like a series of little thumbnails and are a graphic representation of how much one serve of a food contributes to an average day's intake.

The Daily Intake draws its information from the Per serving figures from the Nutrition Information Panel on the back and places it on the front of the pack in a graphic format which is easier to interpret. A picture is faster than reading numbers!

Thumbnails are voluntary

The Daily Intake Guide is a voluntary scheme, which has been developed by the Australian Food and Grocery Council. As of 2013, it appears on over 7,000 food packets.

 Some manufacturers choose to display only the %DI for energy (kJ) while others may include information on energy as well as seven nutrients - protein, fat, saturated fat, carbohydrate, sugars, fibre and sodium.

Some products like breakfast cereals also show four vitamins and the mineral iron. Kelloggs were the first to introduce the %DI in mid-2006 followed by Coca-Cola and McDonalds.

Checkout this example

Take a look at the %DI thumbnails from a pack of Just Right breakfast cereal.

DI Just Right thumbnails

 From the above shot, you can see that a "serve" of 45 grams of Just Right (a large bowl) gives you 8 per cent of your kilojoule (energy) intake, 8 per cent of your protein, 1 per cent of fat, 0.8 per cent of saturated fat, 10 per cent of carbohydrates, 14 per cent of sugars, 0.6 per cent of sodium (salt) and 12 per cent of fibre.

Make sure you understand though just a what a "serve" is. Click here to read my article on serve sizes.

 In contrast, if you eat a Big Mac, the thumbnails tell you that it gives you 23 per cent of your day's theoretical energy - which makes it more of a meal.

DI Big Mac

But, you also getting 50 per cent of your protein along with 40 per cent of your saturated fat and 37 per cent of your day's sodium (not shown) - not a good thing. You are getting an "excess" of saturated fat and sodium relative to your kilojoules.

How do they work out the %Dietary Intake?

You can see the numbers for yourself - they are simply take the figures from the Per serve column on the nutrition panel on the back of the pack. Then they divide them by the average day's total intake.

Nutritionists' gripes

1. The %DI is based on a healthy weight male who consumes 8700 kJ (2300 Calories) per day. If you are a child, female or anyone overweight - all of whom need to consume fewer kilojoules than most males - the numbers won't apply to you.

Take a Big Mac with 2010 kJ as an example again.

  • If you are average man, it provide you with 23 per cent of your day's energy intake.
  • If you are an average woman, your energy needs would be only around 7500 kJ, 1200 less than the average male. Thus a Big Mac would give you 27 per cent of your total (which is 2010/7500 X 100).
  • If you are on a diet and eating only 5000 kJ a day, that same Big Mac would give you a huge 40 per cent of your day's total. You would need to think twice about whether to eat it or not!
  • If you are sporty or very active, you'll burn up more kilojoules and therefore the foods contribute LESS of your DI needs.

Rule of thumb:

  • If you're burning up LESS than an average man, the percentages displayed would be greater than your required daily intake.
  • If you're burning up MORE than the average man, the percentages displayed would be less than your required daily intake.

2. Just using energy (kilojoules) as a way of comparing foods ignores the overall nutrition of a food. It can make unhealthy foods seem like a good choice as it is all about quantity, not quality. There's no judgement as to whether a food is good for you or not - it's left to the consumer to interpret. In contrast, the red Heart Foundation Tick does the work for you in highlighting healthier options with less saturated fat, sodium (but it doesn't tell you how much to eat of them either).

3. The numbers look complicated - there are too many numbers to make it a simple at-a-glance check. If manufacturers rounded the percentages up to the nearest whole number, they would be a lot simpler. [Update from 2013: the numbers are now rounded which is a lot easier!]

The bottom line

For people who aren't numerical and find tables hard to decipher, the thumbnails make the nutrition information panel a little easier to interpret but it's too complicated for people to evaluate foods quickly and easily. It's also male-orientated and given that most often it's still women doing the shopping and trying lose weight, it's just not relevant enough!

    What’s in your favourite tomato pasta sauce, and how much of it? Here are the most popular sauces reviewed for your reading pleasure.

    I’ve rated nine of the most popular tomato pasta sauces in terms of their nutrition, ingredient lists and jar size. You’ll find many of these in your local supermarket. The sauces are ranked:

    • from Italian (Italy grows the reddest full-flavoured tomatoes) to Australian
    • per 100 grams, which is equivalent to 3½ ounces (the standard for comparing food products)
    • by serving size (varies between brands but is generally 100–175 g in size)
    • by ingredient list, jar size and where made (with each product’s website as the source)

    The bottom line

    When you’re next out shopping, run your eyes down the per 100 g column and look for products containing less than 400 mg sodium AND less than 5 g fat (which equals 5% fat). Most of the brands are below these levels. I like Barilla, Sacla, Leggo’s, La Gina and Mutti – but that’s just me!

    You can drink Bundaberg low-sugar ginger beer straight from the can, or pour it into a long glass over ice with a slice of lime.

    Intermittent fasting vs daily calorie restriction

    3 May 2023 by, Catherine Saxelby

    As you probably know already, intermittent fasting (IF) has gained favour as an alternative regimen to daily caloric restriction (DCR). Fasting is shown to extend the lifespan of rats, and has been associated with metabolic benefits in humans, yet the results so far have been inconsistent. So, which regimen is best for healthy weight loss?

    What sort of a diet should you follow to lose that excess weight? These days, it’s pretty confusing with high-protein Keto advocates clashing with plant-protein followers … as well as intermittent fasters, juice-only dieters, no-carb dieters and no-animal (aka plant-based) dieters. Plus all the ads for anti-hunger supplements, meal-replacement shakes and home-delivered meals, more of which somehow appear every day. So, what sort of diet should YOU follow to lose that excess?

    These days, protein shakes aren’t bought by just body builders – they’re so popular that you can readily buy a 400 g tub at your local supermarket or service station. And with tempting claims such as ‘Facilitates muscle toning’, ‘Contains transformation-making protein’ and ‘Tastes incredible, mixes easily’, why wouldn’t you grab one? But protein shakes aren’t the magic answer to all your weight-loss woes. Let’s take a look at what you get for your money.

    The word 'diet' is a turn-off for most people. It sounds hard, unpleasant and unpalatable. Losing weight doesn’t have to be hard AND it doesn’t have mean sticking to a 'diet'. You can forget Paleo, Keto, Vegan and Raw, Gluten-free and Intermittent Fasting. To lose weight, you don’t have to follow any specific diet. What you need is simple, healthy, nutritious food and a few tips and tricks.

    What IS a healthy balanced diet for weight loss?

    16 September 2020 by, Catherine Saxelby

    Healthy weight loss happens when you lose weight slowly and steadily (around 1 kg or 2 pounds weight loss a week). Your goal is to lose weight while still getting your essential nutrients but from smaller portions. You certainly don’t want to be tired with no energy! That’s why you need regular healthy meals and snacks on hand to ensure your vitamins, minerals, omega-3s and fibre needs can be easily met. There is a new range of healthy weight loss meals available and it’s one that I’d like to recommend. With these ready meals, you’ll say goodbye to meal planning, shopping, meal preparation and cooking.
