You’re poisoning your family (and don’t know it): 6 kitchen mistakes making Aussies sick

Australians who believe they are eating well at home could be doing more harm than good, with leading health and wellness expert Dr Vincent warning that everyday food habits are quietly undermining health and contributing to long-term illness.
 

Despite cooking at home being seen as the healthier option, Dr Vincent said many households are unknowingly stripping nutrients from their food and exposing themselves to harmful substances.
 

"People think they're doing the right thing by cooking at home, but in many cases, they are slowly damaging their health without realising it," Dr Vincent said.
 

"It's not just what you eat, it's how you prepare, store and handle it."
 

He warned that with more people cooking at home to save money due to the cost of living crisis, rather than eating out, the risk of long term health implications is on the rise.
 

The six silent mistakes making Australians sick
 

Dr Vincent said there are several common kitchen habits that are reducing nutritional value and increasing exposure to harmful compounds.
 

Overcooking food
 

"Overcooking vegetables destroys essential vitamins, antioxidants and polyphenols that are critical for immune function," he said.
 

"By the time food is served, much of the nutritional value has already been lost."
 

Storing food for too long
 

"Food sitting in the fridge for days continues to degrade," he said.
 

"Even if it looks fine, the nutrient profile has significantly declined, particularly the compounds that support immunity."
 

Using poor-quality plastics
 

"Storing food in low-quality plastic containers can lead to chemical leaching, particularly when reheated," he said.
 

"These chemicals can disrupt hormones and impact long-term health."

Over-processing and excessive chopping
 

"Cutting food too far in advance or into very small pieces accelerates nutrient loss," he said.
 

"Once food is exposed to air, oxidation begins immediately, reducing its effectiveness in supporting the body."
 

Cooking with plastic and cling wrap
 

"Heating food with plastic coverings can release harmful compounds directly into your meal," he said.
 

"This is one of the most overlooked risks in modern kitchens."
 

Using poor-quality cookware
 

"Low-grade metals can leach into food, particularly when cooking acidic ingredients," he said.
 

"Over time, this can contribute to a build-up of unwanted substances in the body."
 

The hidden danger of 'everyday' foods
 

Dr Vincent said another major issue is the increasing reliance on ultra-processed foods.
 

"Many everyday products contain high levels of preservatives, additives and chemicals that place additional stress on the body," he said.
 

"Even foods marketed as 'healthy' can be heavily processed and lack the nutrients your body actually needs."
 

He added that modern diets are often lacking key elements that support resilience and recovery.
 

"Healthy fats such as those found in fish oil play an important role in reducing inflammation, while powerful antioxidants like activated phenolics, naturally sourced from Australian apples, support the body's defence systems," he said.
 

"When these are missing or reduced, the body becomes more vulnerable over time."
 

Why this matters more than people think
 

Dr Vincent said the impact of these habits is not always immediately visible.
 

"This is not about getting sick overnight," he said.
 

"It's about what happens over months and years. Poor nutrition, chemical exposure and degraded food quality slowly weaken the body."
 

He said this contributes to fatigue, weakened immunity, inflammation and increased susceptibility to illness.
 

"People often don't connect their daily habits with how they feel, but the link is very real," he added.

The simple shift that can change everything
 

Dr Vincent said improving health does not require extreme diets or expensive products, but greater awareness and consistency.
 

"Cook food lightly, eat it fresh, reduce exposure to plastics and chemicals and focus on nutrient- dense foods that support the body properly," he said.
 

"These are simple changes, but they have a powerful cumulative effect."
 

A wake-up call for Australian households
 

Dr Vincent said Australians need to rethink what 'healthy eating' really means.
 

"Cooking at home is only healthy if you are doing it properly," he said.
 

"Otherwise, you may be slowly working against your own health without even knowing it."
