In a new study by the National University of Singapore (NUS), scientists have provided new insights that fundamentally change our understanding of the nexus between poor diet and an increased risk of cancer and other diet-related diseases such as diabetes. This research, spearheaded by Professor Ashok Venkitaraman of the Cancer Science Institute of Singapore (CSI Singapore) and the NUS Centre for Cancer Research (N2CR), delves into the biochemical impacts of unhealthy eating habits on our genetic makeup.
Understanding the Link: Methylglyoxal and Cancer Risk

The Role of Methylglyoxal
The team focused on the effects of a chemical called methylglyoxal, a byproduct of glucose breakdown within our cells, which appears to play a pivotal role in cancer development. “Our findings suggest that methylglyoxal is a crucial player in the onset of cancer, particularly in individuals predisposed to the disease due to genetic factors or lifestyle choices,” explained Prof Venkitaraman.
High-Risk Groups Identified
Individuals carrying a faulty BRCA2 gene, which is closely associated with breast and ovarian cancers, show increased sensitivity to the harmful effects of methylglyoxal. This chemical exacerbates DNA damage, serving as an early warning signal for cancer. Furthermore, those with diabetes or pre-diabetes—conditions often linked to poor dietary habits—also exhibit elevated levels of methylglyoxal, correlating with a heightened cancer risk.
“Patients with high methylglyoxal levels may have a higher risk of cancer. Fortunately, this can be monitored through a simple HbA1C blood test and managed with medication and proper diet,” stated Prof Venkitaraman.
Insights from Dr. Li Ren Kong
Dr. Li Ren Kong, a lead researcher in the study, emphasized the broader implications of their findings: “Our research not only explores cancer risk factors in genetically susceptible families but also uncovers a critical mechanism by which diet influences cancer risk through metabolic pathways.”
Revising Cancer Theories: The Impact of Diet on Gene Function
Challenging Knudson’s ‘Two-Hit’ Paradigm
The research revisits and modifies the long-standing “two-hit” hypothesis, suggesting that temporary inactivation of cancer-preventing genes by methylglyoxal could cumulatively increase cancer risk over time due to repeated poor dietary choices or uncontrolled diabetes.
“This revelation highlights the significant impact that lifestyle factors, particularly diet, can have on our genetic defenses against cancer,” remarked Prof Venkitaraman.
Future Directions: Expanding the Research
The NUS team is now poised to extend its research to understand better how metabolic disorders influence cancer risk across different populations in Singapore and throughout Asia. “We are excited about the next phase of our research, which will further elucidate the intricate links between metabolism, diet, and cancer, paving the way for new prevention strategies,” said Prof Venkitaraman.
A Call to Action for Healthier Living
The discoveries made by the NUS research team serve as a potent reminder of diet’s critical role in our health and longevity. By adopting healthier eating habits and managing weight, we can proactively mitigate our cancer risk. This study opens new avenues for scientific inquiry and empowers individuals with the knowledge to make informed choices about their health.
Practical Steps to Reduce Cancer Risk Through Diet
In light of the compelling findings from the National University of Singapore about the link between poor diet and increased cancer risk, here are some actionable steps you can take to improve your diet and potentially lower your risk:
Optimize Your Dietary Choices
1. Incorporate Whole Foods
- What to Eat: Increase your intake of fruits, vegetables, whole grains, and lean proteins. These foods are rich in essential nutrients and antioxidants that can help protect cells from damage.
- Why It Matters: Whole foods are less likely to contribute to the levels of harmful chemicals like methylglyoxal in your body.
2. Reduce Sugar and Processed Foods
- What to Do: Limit sugary beverages, snacks, and processed meals. These often contain high levels of refined sugars and unhealthy fats that can contribute to poor health outcomes.
- Why It’s Important: Reducing these foods can decrease the production of harmful byproducts in your body, possibly leading to DNA damage.
3. Consultation with a Nutritionist
- How to Proceed: Consider consulting a dietitian or nutritionist to tailor a diet plan that suits your health needs.
- Advantage: Personalized advice can help you adjust your diet effectively to reduce cancer risks and manage other health conditions.
Lifestyle Adjustments for Long-term Benefits
4. Maintain a Healthy Weight
- Strategy: Engage in regular physical activity and balance your calorie intake with your energy expenditure.
- Impact: Keeping a healthy weight reduces the risk of developing obesity-related diseases, including various types of cancer.
5. Mindful Eating Habits
- Practice: Adopt mindful eating practices by paying attention to when and how much you eat. Avoid distractions during meals to control your portions and fullness better.
- Result: This can help you maintain a balanced diet and prevent overeating, which is crucial for metabolic health.
6. Support Systems
- Build Networks: Join support groups or online forums where individuals share their experiences and tips for maintaining a healthy diet.
- Why Join: Community involvement provides encouragement and motivation to stick with healthy lifestyle changes.
By taking these practical steps, readers can actively participate in their health management and potentially reduce their cancer risk. Each action contributes to a more significant health and wellness strategy, empowering individuals to make informed decisions that benefit their long-term health outcomes.
