Reheating leftovers is something most people do without thinking. It feels practical, saves money and reduces food waste. But what if this simple kitchen habit is quietly affecting your health? A recent warning by a medical expert has raised concerns about how certain reheated foods may be linked to long-term risks, including pancreatic cancer.
In a YouTube video, Dr Aiden Core explained that many people unknowingly repeat this habit every week. According to him, the issue is not leftovers themselves, but how some foods react when reheated. Over time, these changes inside the body may contribute to conditions linked to pancreatic cancer, which often shows no early symptoms.
Pancreatic Cancer Risk: 5 Foods You Should Be Careful Reheating
The expert highlighted five common foods that may become risky when reheated repeatedly:
- Fried foods (fries, chicken, spring rolls)
Reheating oil-based foods can create harmful compounds. These may damage cells and increase inflammation in the body. - Leafy greens (spinach and similar vegetables)
When reheated, natural compounds may convert into substances linked to health risks. It is better to eat them fresh or cold. - Rice
Improper storage and reheating can allow bacteria to grow. Even reheating may not remove certain toxins completely. - Chicken
Uneven reheating, especially in microwaves, can leave bacteria alive. This may lead to infections and internal stress. - Potatoes
Reheating at high heat can form compounds that may be harmful over long periods.
Dr Core stressed that repeated exposure to such habits may create internal stress and inflammation, which are often discussed in relation to pancreatic cancer risk.

Simple Kitchen Habits To Reduce Pancreatic Cancer Risk
The good news is that small changes can make a difference. The expert suggested:
- Avoid reheating fried food in oil again
- Use an oven or air fryer instead of a microwave when possible
- Eat leafy greens fresh or reheat only once
- Store rice properly and consume it within 24 hours
- Ensure chicken is heated evenly and thoroughly
- Prefer low heat or avoid reheating potatoes multiple times
Why Awareness Matters
One of the biggest concerns around pancreatic cancer is that it develops silently. Many people do not notice symptoms until later stages. This makes everyday habits even more important.
Experts say there is no need to panic, but being aware helps. Making smarter food choices and improving cooking habits can support better health over time. Even small changes in how you handle leftovers may help reduce unnecessary risks linked to pancreatic cancer.
