Nutrition and Longevity: The Science of Eating for a Longer, Healthier Life
Recent advancements in nutritional science have revealed the profound impact our dietary choices can have on our lifespan and overall health
Professor Kristina Norman
Professor Kristina Norman, a leading expert in nutrition and gerontology, shares groundbreaking insights in a recent interview with “Der Spiegel, a German news magazine, that suggest adopting a healthy diet can significantly increase life expectancy, with potential gains of up to 13 years for those who start early. Even more encouraging, individuals who make dietary changes at 60 can add up to 9 years to their lives.
is professor for nutrition and gerontology and divides her time between the German Institute for Human Nutrition (DIfE) and the Department of Geriatrics of the Charite Universitätsmedizin Berlin.
Understanding Age-Related Changes and Nutritional Needs
As we age, our bodies undergo significant changes that affect our nutritional requirements:
1. Body Composition Shifts: Around age 60, we begin to lose muscle mass, bone density, and organ mass, while fat tissue increases. These changes can lead to decreased physical performance and increased health risks.
2. Metabolic Changes: Our resting energy expenditure decreases, meaning we burn fewer calories at rest.
3. Increased Nutrient Needs: Despite needing fewer calories, our bodies often require more of certain nutrients to maintain optimal health
The Western Diet Dilemma
The typical Western diet, characterised by high consumption of saturated fats, animal proteins, salt, simple carbohydrates, and processed foods, is known to promote inflammation and accelerate aging.
This dietary pattern contributes to what scientists call “inflammaging” – a state of chronic, low-grade inflammation associated with agerelated diseases.
Plant-Based Benefits: A Key to Longevity
Professor Norman emphasises the importance of a plant-focused diet rich in vegetables, fruits, legumes, and whole grains. Such a diet provides essential nutrients, including polyphenols and carotenoids, which have anti-inflammatory and potentially cancer-protective properties
Dietary Recommendations for Healthy Aging
Mediterranean-Style Diet
This eating pattern, rich in vegetables, legumes, fish, nuts, and olive oil, with moderate wine consumption, is associated with increased longevity.
Protein Intake
For individuals over 65, increased protein intake (1 to 1.5 grams per kilogram of body weight daily) is crucial to maintain muscle mass and prevent frailty
Microbiome Support
Consuming a variety of plant-based foods and fermented products promotes a healthy gut microbiome, which plays a crucial role in overall health and aging.
Nutrient Focus
Certain nutrients become more important as we age. For example, vitamin D requirements increase, as it helps maintain muscle function and prevent falls.
The Power of Dietary Changes
It’s never too late to improve your diet. Even individuals who switch to a healthier diet at 60 can potentially gain up to 9 additional years of life. However, the earlier one adopts healthy eating habits, the greater the potential benefits
The best time to take action was yesterday. The second best time is today
Vietnamese Cuisine: A Model for Healthy Eating
Interestingly, traditional Vietnamese cuisine aligns well with many of these dietary recommendations:
1. Plant-based focus: Vietnamese cuisine naturally incorporates a wide variety of vegetables and herbs, providing essential nutrients and antioxidants.
2. Balanced protein sources: While Western diets often rely heavily on red meat, Vietnamese cuisine balances animal proteins with plant-based options like tofu and legumes.
3. Cooking methods: Vietnamese dishes often use lighter cooking techniques like steaming and boiling, as opposed to the frying common in Western cuisine.
This alignment makes Vietnamese food a potential model for healthy eating patterns that promote longevity and wellness.
Beyond Diet: The Future of Nutrition Science
Professor Norman points to exciting developments in personalised nutrition. With advancements in measurement technologies and artificial intelligence, we may soon be able to create individualised nutrition programs based on factors like microbiome composition and genetic makeup.

Practical Steps for Longevity Through Nutrition
1. Increase plant-based foods: Aim to fill half your plate with vegetables at each meal.
2. Choose whole grains: Replace refined grains with whole grain alternatives.
3. Incorporate lean proteins: Balance animal proteins with plant-based sources like legumes and tofu.
4. Embrace healthy fats: Use olive oil and include nuts and seeds in your diet.
5. Stay hydrated: Drink plenty of water throughout the day.
6. Practice portion control: Eat mindfully and listen to your body’s hunger and fullness cues.
7. Limit processed foods: Reduce intake of packaged snacks, sugary drinks, and fast food.
