In the World of Diets, Which One Is Best for Healthspan & Lifespan?
With an overwhelming number of diets flooding the nutrition landscape, it can be challenging to discern the best dietary approach for optimal health and longevity. Vegetarian, pescatarian, vegan, paleo, ketogenic, carnivore, DASH, Ornish, Noom, Zone, South Beach, Atkins—the list goes on. Amidst this sea of options, one diet consistently emerges as the clear winner in promoting healthspan & lifespan: the Mediterranean diet.
Recent scientific evidence further strengthens the case for the Mediterranean diet’s unparalleled benefits. A study published in 2023 examined seven different diets and their outcomes regarding all-cause mortality, cardiovascular mortality, stroke, and non-fatal myocardial infarction. The Mediterranean diet emerged as the top performer across all these critical markers. Its position as diet number one is visually apparent in the following table, with the dot indicating superior outcomes when it’s furthest to the left.
While countless diets claim to offer the ultimate solution, the Mediterranean diet stands out as a shining example of a dietary pattern that consistently delivers great results. It goes beyond mere trends and fads, offering a centuries-long, time-tested approach to nutrition that has been embraced for generations.
The Main Principles of the Mediterranean Diet
The Mediterranean diet is inspired by the traditional eating patterns of countries bordering the Mediterranean Sea, such as Greece, Italy, and Spain. Although variations exist and diets like the Japanese Okinawan diet have comparable results, there are common principles that define this dietary pattern:
Plant-Based Foods: The diet emphasizes the consumption of plant-based foods as the cornerstone, including fruits, vegetables, nuts, legumes, and whole grains. These foods provide essential nutrients, fiber, prebiotics, and antioxidants that support overall health.
Olive Oil: Olive oil is the primary source of fat in the Mediterranean diet. Its abundant presence in cooking and salad dressings provides valuable health benefits. Olive oil contains oleic acid, which helps reduce inflammation and fight heart disease. Additionally, it contains hydroxytyrosol, a polyphenol that possesses anti-inflammatory properties.
Fish and Seafood: The Mediterranean diet incorporates moderate amounts of fish and seafood rich in omega-3 fatty acids. These beneficial fats support brain health and cardiovascular function and help reduce inflammation.
Lean Protein Sources: The diet includes lean protein sources such as poultry, eggs, and fermented dairy products. Including these lean protein, options ensure an adequate intake of essential nutrients without excessive saturated fat content.
Limited Red Meat: While red meat is not entirely eliminated from the diet, it is consumed in limited quantities. Red meat, which typically refers to beef, pork, or lamb, is recognized for its higher saturated fat content than lean protein sources like chicken breast.
Herbs and Spices: Herbs and spices enhance flavor in Mediterranean cuisine instead of relying heavily on salt. These natural flavor enhancers are also rich in polyphenols, which have numerous health benefits.
Moderate Red Wine Consumption: While red wine is enjoyed in moderation with meals in some Mediterranean cultures, caution is advised. Alcohol consumption, even in small amounts, can adversely affect health.
The Main Health Benefits of The Mediterranean Diet
The Mediterranean diet offers a wide range of scientifically proven health benefits:
Improved Cardiovascular Health: Studies have consistently linked adherence to the Mediterranean diet with a reduced risk of cardiovascular diseases, including heart attacks and strokes. It has also shown superior results in comparison to low-fat diets. Follow these 10 tips to improve your heart health.
Lower Risk of Type 2 Diabetes: Following the Mediterranean diet is associated with better blood sugar control and a decreased risk of developing type 2 diabetes.
Weight Management and Obesity Prevention: The Mediterranean diet promotes long-term weight loss and maintenance due to its nutrient-dense, balanced approach to eating. Find out how insulin resistance & high body fat accelerate aging.
Reduced Cancer Risk: Higher adherence to the Mediterranean diet is linked to a decreased risk of various cancers, such as colorectal, breast, and prostate cancers.
Enhanced Cognitive Function: The Mediterranean diet has been associated with improved cognitive function, reduced risk of Alzheimer’s disease, and slower cognitive decline. Discover our tips to reduce the risk of dementia and Alzheimer’s disease.
Mood and Mental Health Benefits: Adherence to the Mediterranean diet is linked to a reduced risk of depression and improved mental health.
Increased Longevity and Reduced Mortality: The Mediterranean diet is associated with reduced overall mortality rates and increased life expectancy. It has demonstrated superior outcomes compared to low-fat and low-carb diets.
Nutrient Diversity and Microbiome Health: The Mediterranean diet’s wide variety of natural foods reduces the risk of nutrient deficiencies and promotes a healthy gut microbiome.
Compliance: More agreeable than most other diets means that it has higher adherence and lower dropout rates.
The Mediterranean Diet’s Impact on Longevity
The impact that the Mediterranean diet has, according to the latest longevity research tools, particularly epigenetic biological age tests, has been a subject of interest. Recent studies have shed light on the rejuvenating effects of this diet on biological age clocks, with promising implications for overall health and aging.
A study published in GeroScience revealed that the Mediterranean-like diet exhibits a significant rejuvenating impact on an epigenetic biological age clock. The findings suggested that this effect is not solely attributed to its influence on the immune system. In addition to improving immune function, the diet also plays a role in enhancing biological aging through specific dietary factors.
Certain dietary components have been identified as contributors to improved epigenetic age. These include consuming fish, fruits, vegetables, and poultry, particularly beneficial for the immune system’s biological age. Furthermore, maintenance co-factors such as vitamins B12, folate, and others play a role in DNA preservation and contribute to positive epigenetic age outcomes.
Conversely, several factors have been identified as detrimental to epigenetic age. These include high levels of insulin and glucose, elevated C-reactive protein (an inflammatory marker), high body mass index and waist-to-hip ratio, increased triglycerides, elevated systolic blood pressure, and low HDL cholesterol levels. By addressing these factors, individuals can potentially lower their biological ages as measured by various epigenetic clocks.
Further examination reveals that controlling the intake of eight key dietary components yields favorable outcomes in terms of lower biological ages across three major epigenetic clocks (the third-generation clock DunedinPace, the GrimAge clock, and the PhenoAge clock). These components include increasing vegetable and fruit consumption, incorporating nuts and legumes, opting for whole grains, choosing low-fat dairy over full-fat alternatives (we recommend that you cut back on dairy for a number of reasons), reducing the consumption of red and processed meats, limiting sugar-sweetened beverages, and reducing sodium intake.
By following these dietary guidelines, individuals can positively influence their biological ages as measured by the latest epigenetic clocks.
Going Beyond the Mediterranean Diet with the NOVOS Longevity Diet
Drawing from the latest research, the NOVOS Longevity diet introduces modifications to traditional Mediterranean dietary patterns. One key modification is the recommendation to replace starches with more nutrient-dense options like mushrooms, vegetables, legumes, or quinoa. This helps keep glucose and insulin levels low and provides a greater abundance of polyphenols, vitamins, and minerals.
Another suggestion is to incorporate teas and coffees as alternatives to soft drinks and water. Teas and coffees are rich in antioxidants and polyphenols, known to extend both healthspan and lifespan.
Additionally, dairy milk can be substituted with plant-based alternatives, while dairy products like cheese and yogurt can still be enjoyed in moderation. It is advised to minimize alcohol consumption as much as possible.
Maintaining diet diversity by including at least 30 or more natural ingredients per week is also emphasized. Regular consumption of fermented foods is encouraged for their probiotic benefits. To ensure essential nutrient needs are met, supplementation is recommended to address any deficiencies. Lastly, supplementing with proven longevity ingredients can further support overall health and longevity goals. By integrating these modifications, the NOVOS longevity diet aims to optimize the Mediterranean diet for enhanced well-being and increased lifespan.
