Researchers from Italy and China came together to study two famous healthy eating styles: the Mediterranean diet from Southern Europe and Cantonese cuisine from China. By comparing these two traditional ways of eating, scientists discovered they share similar benefits for heart health, weight management, and cancer prevention. Both diets focus on fresh vegetables, whole grains, and healthy fats rather than processed foods. This research shows that eating the way people have eaten for thousands of years in these regions may be one of the best ways to stay healthy and prevent serious diseases as we age.

The Quick Take

  • What they studied: How two traditional diets—Mediterranean (from countries around the Mediterranean Sea) and Cantonese (from southern China)—help people stay healthy and prevent diseases
  • Who participated: This wasn’t a study with volunteers. Instead, experts from Italy and China shared their knowledge at a conference about these two eating styles and reviewed existing scientific research
  • Key finding: Both the Mediterranean and Cantonese diets appear to protect heart health, help maintain healthy weight, and may reduce cancer risk because they emphasize whole foods, vegetables, and healthy fats
  • What it means for you: You don’t need expensive supplements or complicated diet plans. Eating more like people in Mediterranean countries or southern China—with lots of vegetables, whole grains, and natural foods—may help you live longer and healthier. However, this is based on general patterns, not a controlled experiment, so results vary by person

The Research Details

This research is different from typical studies where scientists test one group of people against another. Instead, experts from Italy and China held a multi-day meeting where they presented what they know about Mediterranean and Cantonese diets. They looked at the history of these diets, how they’re prepared, what nutrients they contain, and what scientific research already shows about their health benefits.

The researchers examined both diets side-by-side to find similarities and differences. They focused on how these eating styles affect the heart, metabolism (how your body uses energy), cancer risk, and overall aging. They also discussed how these traditional foods could be used in modern medicine to prevent diseases.

This type of research is called a ‘review’ because experts are reviewing and summarizing existing knowledge rather than conducting a new experiment with participants.

This approach is valuable because it brings together experts from different countries who study these diets in their own cultures. By comparing two successful dietary traditions, scientists can identify common healthy eating patterns that work across different populations. This helps us understand what makes a diet truly healthy, rather than just following trendy diet fads.

This research summarizes expert knowledge and existing scientific studies rather than testing new participants. That means it’s based on proven information, but it’s not as strong as a controlled experiment where scientists directly test people. The findings are reliable for understanding general patterns about these diets, but individual results may vary. The research was published in a respected journal focused on aging and health, which adds credibility.

What the Results Show

Both the Mediterranean and Cantonese diets show strong benefits for heart health. They both emphasize vegetables, whole grains, legumes (beans and lentils), and healthy fats like olive oil or sesame oil, while limiting red meat and processed foods. These similarities suggest that eating this way protects your cardiovascular system—the heart and blood vessels that carry blood throughout your body.

Both diets also appear helpful for maintaining a healthy weight and metabolism. When your metabolism works well, your body efficiently converts food into energy and maintains healthy blood sugar levels. This reduces the risk of developing type 2 diabetes and obesity.

The research suggests both diets may help prevent certain cancers. Scientists believe this is because these diets are rich in antioxidants and anti-inflammatory compounds—natural substances in foods that protect your cells from damage. The emphasis on plant-based foods rather than processed meats appears particularly protective.

Another important finding is that both diets work best when combined with an active lifestyle and strong social connections. People in Mediterranean countries and southern China traditionally eat meals with family and friends, stay physically active, and maintain close community ties—all factors that contribute to better health outcomes.

The research highlights the importance of ‘functional foods’—foods that provide extra health benefits beyond basic nutrition. In the Mediterranean diet, examples include olive oil and fish rich in omega-3 fatty acids. In Cantonese cuisine, examples include ginger, garlic, and various herbs used in traditional medicine. Both cultures use these foods intentionally to promote health.

The research also discusses how public policy can support these healthy eating patterns. Making traditional, whole foods affordable and accessible helps more people adopt these diets. The study suggests that governments should promote these evidence-based eating styles rather than allowing processed foods to dominate.

This research aligns with decades of scientific studies showing the Mediterranean diet’s health benefits. The novelty here is the detailed comparison with Cantonese cuisine, which has received less scientific attention in Western research. By showing these similarities, the research validates that healthy eating principles aren’t unique to one culture—they appear across different successful food traditions. This supports the idea that certain dietary principles (lots of vegetables, whole grains, healthy fats, minimal processed foods) are universally beneficial.

This research is a review of existing knowledge rather than a new experiment, so it can’t prove cause-and-effect as strongly as a controlled study could. The findings represent general patterns, but individual people may respond differently based on genetics, activity level, and other factors. Additionally, while the research discusses both diets, most scientific studies have focused more on the Mediterranean diet, so there’s less research specifically about Cantonese cuisine. The research also doesn’t account for modern versions of these diets that may include more processed foods than traditional versions.

The Bottom Line

Based on this research, consider adopting more Mediterranean or Cantonese eating patterns: eat plenty of vegetables and fruits, choose whole grains over refined grains, use healthy oils like olive oil, include fish and legumes as protein sources, limit red meat and processed foods, and enjoy meals with family and friends. These changes appear to have strong evidence supporting their health benefits. Start with small changes—add one vegetable to your meals, try fish twice a week, or switch to whole grain bread—rather than overhauling your diet overnight.

Everyone can benefit from these eating patterns, but they’re especially important for people concerned about heart disease, weight management, diabetes prevention, or cancer prevention. Older adults may find these diets particularly helpful for maintaining health and independence. People with existing heart disease or diabetes should consult their doctor before making major dietary changes. These recommendations are general and don’t replace personalized medical advice from your healthcare provider.

You may notice improved energy levels and digestion within 2-4 weeks of dietary changes. Heart health improvements typically take 3-6 months to show up in blood tests. Weight changes depend on your starting point and overall calorie intake but often become noticeable within 4-8 weeks. The cancer-prevention and longevity benefits develop over years and decades of consistent healthy eating.

Want to Apply This Research?

  • Track daily vegetable and fruit servings (goal: 5+ servings per day) and weekly fish consumption (goal: 2-3 times per week). Log the type of oil used in cooking and note meals eaten with family or friends to capture the social component of these diets.
  • Use the app to plan one Mediterranean or Cantonese-inspired meal per week, gradually increasing to more meals. Set reminders to try a new vegetable or herb each week. Create a shopping list based on traditional ingredients from these diets to make grocery shopping easier and more intentional.
  • Monthly, review your vegetable variety, protein sources, and meal patterns. Take quarterly photos of typical meals to visually track dietary changes. Every 3 months, note energy levels, digestion quality, and how clothes fit as practical health indicators. Consider annual check-ins with blood work to monitor cholesterol and blood sugar if relevant to your health goals.

This research is a review of expert knowledge and existing studies, not a controlled experiment. Individual results vary based on genetics, overall lifestyle, and personal health conditions. Before making significant dietary changes, especially if you have existing health conditions, take medications, or have food allergies, consult with your healthcare provider or a registered dietitian.
