When did packet food become so normal?

When did packet food become so normal?

If you walk through a supermarket today, it’s easy to think this is just… normal.

Snack packets.
Protein bars.
Yoghurt pouches.
Crackers in mini packs.
Lunchbox snacks with ingredient lists longer than a school permission slip.

And honestly? Many of us have grown up believing this is simply what modern food looks like.

But here’s the fascinating part…Just one or two generations ago, this wasn’t normal at all.

I was listening to a recent podcast this week discussing ultra-processed foods, and one comment really stuck with me:

“I don’t think younger parents realise you can actually live without things in little packets with 20 ingredients.”

And wow. That hit me.

Because for many children today — and honestly many adults too — packet food has become the default.

Not occasionally.
Not for convenience sometimes.
But as the foundation of everyday eating.

So what actually is an ultra-processed food?

Researchers now define ultra-processed foods (UPFs) as foods:

  • made in a factory
  • with multiple 'industrialised' ingredients
  • designed for convenience and long shelf life
  • containing ingredients you wouldn’t use at home

Things like:

  • emulsifiers
  • modified starches
  • gums
  • flavour enhancers
  • protein isolates
  • artificial sweeteners
  • colourings
  • preservatives

A simple way shared in the podcast was:

“If your grandmother wouldn’t recognise the ingredients, it’s probably ultra-processed.”

A helpful starting point.

Why are experts becoming more concerned?

For years, we mostly talked about unhealthy food in terms of: fat, sugar, salt & calories.

But now researchers are looking beyond nutrients and asking a different question:

What does ultra-processing itself do to our bodies?

And the research is growing rapidly.

The recently released Lancet Series on Ultra-Processed Foods and Human Health brings together accumulating evidence linking diets high in ultra-processed foods with poorer health outcomes.

Researchers are now suggesting the evidence is becoming strong enough to start making causal links between high UPF intake and disease risk. That’s a huge shift.

Why ultra-processed foods may affect health

One of the experts in the podcast explained it in three surprisingly simple ways.

1. Ultra-processed foods push out the “good stuff”

The more ultra-processed foods we eat, the less room there is for:

  • fruit
  • vegetables
  • legumes
  • nuts and seeds
  • quality proteins
  • wholegrains

It’s not only about what we are eating. It’s also about what we’re not eating anymore.

2. They’re designed to make us eat more

This part is where the science and palatability of food has taken over.

Ultra-processed foods are often:

  • soft
  • quick to chew
  • easy to overeat
  • engineered to feel irresistible

The podcast shared that large food companies employ thousands of food scientists whose role is to create products that are hyper-palatable and ultra-profitable. These foods dissolve quickly in the mouth, require less chewing and often bypass our normal fullness signals.

Which explains why it’s very easy to keep reaching for “just one more handful.”

3. Our bodies are exposed to more industrial additives

Ultra-processed diets also expose us to more “xenobiotics” — essentially substances our bodies wouldn’t traditionally encounter in whole foods. Researchers are now exploring how combinations of additives, packaging chemicals including plastics and industrial ingredients may interact with:

  • gut health
  • inflammation
  • metabolism
  • long-term disease risk

Importantly, this doesn’t mean panic over every packaged food. But it does raise important questions about how heavily processed modern diets have become.

The biggest shift parents can make

Busy families need convenience sometimes. The goal isn’t to eliminate every packaged food.

The goal is simply to move back towards more real food, more often.

More foods grown in nature.
More foods we recognise.
More foods our grandparents would probably call “food.”

Some realistic ideas for busy families

Instead of focusing on restriction, try:

  • adding fruit alongside packaged snacks
  • upgrading one lunchbox item at a time
  • serving snacks on a plate instead of straight from packets
  • using leftovers more often
  • choosing simpler ingredient lists where possible
  • cooking one extra homemade item each week

Small shifts count.

Why this conversation matters

Right now, Australian children and teenagers are among the highest consumers of ultra-processed foods globally.

Some estimates suggest UPFs now make up:

  • 40–50% of total calories overall
  • and up to 60–80% for some children and teens

That’s an enormous change in a relatively short period of time.

And many families simply haven’t realised how much our food culture has shifted.

Final thoughts

This conversation is all about awareness.

Because once parents understand:

  • how processed many foods have become
  • how these products are designed
  • and how food affects energy, mood, focus and wellbeing

…it becomes much easier to make small, practical changes that genuinely support family health.

Not perfectly. Not all at once. But one lunchbox, one meal and one choice at a time.
