The other day, I watched a video of how crab sticks are made.
When you see how a crab stick is made, trust me, you’ll never want to eat one ever again (you can watch the horrifying video here).
Spoiler alert: There’s no actual crab meat in a crab stick.
Like many people of my generation, I grew up eating all sorts of ultra-processed foods. I developed a taste for chemical additives.
I remember always feeling hungry. I could never stop at just one chip, one biscuit, or one bowl of sugary cereal. I constantly craved more. I thought the reason I couldn’t stop at one chip was that I lacked willpower.
But it turns out that wasn’t the problem.
No one has a willpower problem when it comes to ultra-processed foods. As gastroenterologist Dr Trisha Pastricia explains in her book You’ve Been Pooping All Wrong:
“[ultra-processed foods] have been engineered to overcome our body’s normal signalling processes telling us we’re full, providing quick glucose spikes and driving us to eat more.”
So please, don’t blame yourself for eating that whole packet of chips. Blame the ultra-processed food industry!
In this blog, I look at the science behind why ultra-processed foods are so harmful to our health and what we can do to minimise their consumption.
It’s not my intention to overwhelm or scare you. My intention is to increase your awareness so you can make more informed decisions about what you eat.
We’ve been manipulated by the ultra-processed food industry
Many of us trust food manufacturers and the government to act in our best interests. But researchers who study the harms associated with ultra-processed foods will tell you this is completely naïve thinking.
I recently discovered The Lancet Series on Ultra-Processed Foods and Human Health. If you’re not familiar with The Lancet, it’s one of the top medical journals.
The series also examines the strategies used by big food corporations to completely transform our food system, maximising profits at the expense of public health.
To launch this Lancet Series, an event was held (and streamed online) where the researchers presented their key findings.
I watched this movie-length event online (you can watch it here). By the end, I felt angry by the conduct of the ultra-processed food industry, but inspired by these courageous researchers who were taking them on!
I believe this is among the most important work on food this decade. I encourage you to take the time to watch this launch event that unpacks the research. Here are six things I learnt from this Lancet Series on ultra-processed foods:
1. Ultra-processed food corporations are like Big Tobacco
Both industries are dominated by powerful corporations whose profits depend on driving overconsumption.
The ultra-processed food industry uses strategies straight from the Tobacco playbook. They employ sophisticated marketing strategies to build lifelong customers, fund studies to create doubt and confusion, and engineer their products to have us reaching for more.
2. Ultra-processed food products are more than just fast food
Ultra-processed food products are attractive products made with cheap ingredients and additives to maximise industry profits.
They contain things you wouldn’t typically find in your kitchen, such as protein isolates, emulsifiers, artificial colours (e.g., Ammonia Caramel 150c), and flavourings (e.g., Disodium 5′-ribonucleotide 635). Think soft drinks, chips, lollies, muesli bars, and fruit-flavoured yoghurts.
When I tried to explain ultra-processed foods to a friend, she said, “But aren’t all foods processed to some extent? Pasta is processed! Cheese is processed!” Yes, that’s true. But pasta and cheese are significantly less processed compared to ultra-processed foods.
This is where the NOVA food classification system can help simplify things.
This system was developed by Brazilian epidemiologist Professor Carlos Monteiro and his team at the Center for Epidemiological Studies in Health and Nutrition. This system categorises foods into groups based on the extent and purpose of processing.
How much of your diet comes from the foods in category 1?
3. Ultra-processed foods have displaced real food
Professor Monteiro said that in the last 20 years, we’ve seen a big shift in people’s dietary patterns. The ultra-processed foods in category 4 have displaced the foods in categories 1-3.
Instead of drinking water, we crack open a can of soft drink or a juice box. Instead of having a bowl of oats for breakfast, we have a bowl of sugary cereal. Instead of pasta with a veggie bolognese sauce, we have a packet of store-bought Mac & Cheese or a frozen microwave meal for dinner.
In other words, most people are no longer cooking meals at home like our grandmas used to. They are eating ultra-processed foods that contain ingredients grandma would have baulked at.
4. Ultra-processed foods have led to an increase in chronic diseases
When proper meals that are made from healthy whole foods are replaced by ultra-processed foods, this leads to serious problems.
Studies show that the more ultra-processed foods you eat, the more fat, salt and sugar you consume, and the less fibre and protein you consume.
An overwhelming body of research shows that consumption of ultra-processed foods is associated with many chronic diseases, including Type 2 diabetes, obesity, depression, and cardiovascular diseases.
There’s also this nasty little thing called xenobiotics that ultra-processed foods contain.
Xenobiotics are toxic chemical compounds, such as BPA, emulsifiers, artificial sweeteners, and flavourings, that we are not physiologically adapted to consume.
As Professor Carlos Monteiro said:
“This is the perfect storm for chronic disease.”
5. The ultra-processed food industry has deskilled us
Not only are these food corporations harming our health and reducing our lifespan, but they have deskilled us. They have robbed us of the opportunity to develop valuable cooking skills.
As one researcher said, “Why cook when you can get takeaway?”
The message that came through loud and clear was that these companies do not care about our health. Their business model is all about maximising profits. End of story.
6. We need a real food revolution led by politicians
It shouldn’t just be up to the individual to make dietary changes. It’s clear that our current food system needs to change.
We need regulations that stop these ultra-processed food corporations from marketing their products to children. We need to tax these food products so corporations don’t make such massive profits. We need to make healthy foods (fruits and vegetables) more affordable for families, and much, much more.
But until we have strong political leadership to push for systemic change, what can we do right now for ourselves to fight back and reclaim our health?
Here are seven things you can do to take back your power:
1. Start cooking
We can start by cooking more meals at home. Every meal you cook is you taking back your power from the ultra-processed food industry. It’s you filling your body with the nutrients, phytochemicals, and fibre you need to function well.
Become someone who refuses to give their hard-earned money to these corporations that are chipping away at our health. You can do this by stepping into your kitchen and cooking a nourishing meal.
You don’t have to cook every day. To make your life easier, try batch cooking or as they say, “cook once, eat twice”. Personally, I like spending a couple of hours on a Sunday prepping some meals for the week ahead.
2. Don’t know how to cook? It’s time to learn
It’s never too late to learn how to cook. I didn’t learn how to cook until I was in my thirties. When I finally picked up some basic cooking skills, it was an absolute game-changer.
If you’re new to the world of home cooking, never fear. I recommend starting with some basic kids’ cookbooks (find healthy ones), an online cooking course on a platform like Rouxbe, or online videos of other people cooking (e.g., Jenny Can Cook).
The thing about cooking is it’s a skill. It’s something you need to practice. With time, you’ll get better. Before you know it, you’ll see yourself as someone who takes pride in cooking and fueling up on nourishing meals.
3. Download and start using Yuka
Yuka is a free app that informs and empowers people to make better food choices. Here’s how it works:
When you’re at the shops, you use the app to scan the barcode of the food product. It will rate the food item based on nutritional quality, the presence of additives, and the exposure to pesticides.
It is 100 per cent independent, which means it doesn’t take money from the ultra-processed food industry or any food brands for that matter.
4. Invest in basic cooking tools
Cooking requires some basic equipment, and it’s worth the investment. You’ll get that money back plus more life energy and better health.
So, what do you need to get cooking?
As a bare minimum, you’ll need a good chopping knife, a chopping board, a pot, a wooden spoon, a tea towel, some measuring spoons and cups, mixing bowls, and a stove.
If you don’t have access to a stove, consider investing in an Instant Pot (see point 5).
5. Invest in an Instant Pot
I own my fair share of kitchen appliances, but if I had to pick my favourite it would be my Instant Pot. An Instant Pot is an electric pressure cooker that allows you to get a healthy dinner on the table quickly.
In my Instant Pot, I have made delicious pasta dishes, fried rice, soups, and curries. Once you get the hang of using it, you’ll be whipping up dinner faster than it takes to order takeaway and have it delivered to your door. Best of all, an Instant Pot won’t break the bank (I got my 8L Instant Pot on sale for $200).
6. Embrace the Brazilian food guidelines
In the Lancet series, the researchers said we need to shift from a focus on reducing fat, salt, and sugar in our meals to reducing our overall consumption of ultra-processed foods. This is what the Brazilian food guidelines set out to achieve.
The Brazilian food guidelines encourage people to eat whole foods that are minimally processed and to enjoy sitting down and sharing meals with others.
Instead of focusing on individual nutrients, the Brazilian food guidelines are a joyous celebration of food. For example, here are some of my favourite recommendations from the Brazilian food guidelines:
- Make unprocessed or minimally processed foods the basis of your diet
- Avoid ultra-processed products
- Eat regularly and carefully in appropriate environments and, whenever possible, in company
- Shop in places that offer a variety of natural or minimally processed foods
- Develop, exercise and share cooking skills
- Plan your time to make food and eating an important part of your life
- Be wary of food advertising and marketing
7. Have healthy snacks ready to go
Psychologist Dr Ashley Gearhardt asks us to consider what small steps we can take to remove the most harmful ultra-processed foods from our diets.
One easy place to start is with snacks.
She encourages us to think about having easy to prepare snacks, such as fruit and nuts, that we can have nearby in case we get hungry. She says you never want to be in a position where you feel like you’re starving and the only thing available are ultra-processed foods.
So doctor’s orders: stock up on healthy snacks!
To sum up
The researchers involved in this Lancet series made it clear: it’s not about never eating ultra-processed foods. The goal is to reduce your intake of these harmful food products and boost your intake of real foods. This is how you take better care of yourself.
What I’ve found is that once you start replacing ultra-processed foods with real foods, you kick-start a self-reinforcing feedback loop. Your brain and body begin to feel fantastic.
Every real meal you eat helps you be more clear-headed, which in turn helps you make better food choices. Before you know it, instead of craving chips and soft drinks, you’ll develop a taste for real food rather than chemically enhanced food products.
This is how we can change our lives and the way we feel. One bite at a time.
