The 5 biggest food marketing lies we've been sold

If you've ever felt confused about what to eat, you're not alone.

One minute we're told fat is bad. The next minute we're told bread is a great source of protein. Then we see a processed cereal with a high Health Star Rating and wonder if it's actually healthy.

The truth is, food marketing is designed to sell products, not necessarily improve your health.

Let's bust five of the biggest food myths that continue to confuse people. 

 

Lie #1: Fat Makes You Fat

For decades, people were told to avoid fat if they wanted to lose weight.

The result?

Supermarket shelves filled with low-fat yoghurts, low-fat snacks, low-fat desserts and low-fat everything.

The problem is that when manufacturers remove fat, they usually replace it with sugar, starches and additives to improve the taste.

Healthy fats are actually essential for your body. They help support hormone production, brain function, nutrient absorption and keep you feeling satisfied after meals.

Foods like avocado, eggs, nuts, seeds, olive oil and quality animal proteins can all be part of a healthy diet.

The real problem isn't healthy fat. It's often the ultra-processed foods that come with it.

 

Lie #2: High-Protein Bread Is A Great Source Of Protein

Have you noticed all the "high-protein" breads appearing on supermarket shelves?

Let's do some simple maths.

Many of these breads contain around 10 grams of protein (and not amazing protein) per two slices but you will also be getting over 14g of carbs, which equals a big blood sugar spike. 

That sounds impressive until you compare it with real protein foods.

Two eggs provide around 12 grams of complete protein, with no blood sugar spike, plus vitamins, minerals and healthy fats. 

A chicken breast can provide over 30 grams of protein.

A piece of salmon can provide 25–30 grams of protein. 

If your goal is to build muscle, lose weight, improve energy or stay full for longer, focus on real protein foods like eggs and meats. 

 

Lie #3: Margarine And Spreads Are Heart Healthy

For years we were encouraged to swap butter for margarine because it was supposedly better for our hearts.

Many spreads are highly processed products made using refined vegetable oils, emulsifiers, colours, flavours and preservatives.

Meanwhile, butter has been consumed for generations and contains naturally occurring fats and fat-soluble vitamins.

Rather than focusing on clever marketing claims, ask yourself a simple question:

"Did this food come from nature or from a factory?"

The less processing, the better.

Whole foods are usually the safer bet.

 

Lie #4: You Have To Count Calories To Lose Weight

This is one of the most frustrating myths of all.

While calories somewhat matter, your body is not a calculator.

Different foods affect hunger, hormones, blood sugar and cravings in very different ways.

For example, 500 calories of steak, vegetables and avocado will usually keep you fuller for much longer than 500 calories of biscuits and soft drink.

When people focus only on calories, they often end up hungry, miserable and constantly fighting cravings.

Instead, focus on the Carefree Three:

✔ Protein

✔ Healthy fats

✔ Fibre

These foods naturally help control hunger, steady blood sugar and make it easier to eat the right amount without constantly counting every bite.

 

Lie #5: The Health Star Rating Means A Food Is Healthy

This one catches a lot of people.

Many highly processed products receive surprisingly high Health Star Ratings.

Meanwhile, some simple whole foods receive lower ratings or no rating at all.

The Health Star Rating looks at selected nutrients and formulas, but it doesn't necessarily tell you how processed a food is or whether it supports long-term health.

A product can still be loaded with refined starches, artificial ingredients and industrial seed oils while displaying an impressive star rating on the front.

My advice?

Ignore the stars and read the ingredient list.

The fewer ingredients, the better.

If you can recognise the ingredients and pronounce them, you're usually heading in the right direction.

 

The Bottom Line

The food industry spends billions of dollars convincing us to buy products.

Your body doesn't need clever marketing.

It needs real food.

Prioritise quality protein, healthy fats, plenty of vegetables and fibre-rich foods. Keep things simple and don't be fooled by flashy packaging, protein claims, low-fat labels or star ratings.

When you eat foods that nourish your body, something amazing happens, you stop feeling confused, your energy improves, your cravings settle down and healthy eating becomes much easier.

Sometimes the healthiest foods don't have a marketing department at all.
