- Greater adherence to the Mediterranean diet was associated with a lower risk of mortality in older adults.
- The study measured dietary biomarkers as opposed to depending solely on food frequency questionnaires.
- Experts agree the Mediterranean diet is beneficial at all life stages but is more encompassing of many different foods than the study may suggest.
Although the Mediterranean diet is often ranked the top overall diet by multiple news outlets, few studies have relied on biomarkers to determine the impact of the Mediterranean diet on longevity.
But the InCHIANTI study, which followed more than 600 participants over the course of 20 years, has demonstrated that adherence to the diet may be associated with a lower risk of mortality in older adults. Here is what you need to know.
About The Study
The InCHIANTI Study followed 642 participants—56% of whom identified as female—age 65 or older for 20 years. At the baseline, researchers measured serum concentration of biomarkers that are associated with intake of vegetables, legumes, fruits, nuts, cereals, fish, and olive oil. Serum resveratrol was also measured.
The study revealed a statistically significant correlation between adherence to a Mediterranean diet and lower all-cause mortality. It also demonstrated a relationship between how much Mediterranean food people consumed and their overall mortality.
Where the Mediterranean Diet Originates
While Italy, Greece, and Spain may come to mind at the mention of the Mediterranean diet, it is important to note the diversity of the countries bordering the actual body of water in question. Abbie Gellman, MS, RD, CDN, a chef and author of “The Mediterranean DASH Diet Cookbook,” notes the similarities in cuisine.

“The Mediterranean diet focuses on a region made up of 21 countries—all of which border the Mediterranean sea,” says Gellman. “While the exact flavor profiles and cuisines may differ, they all generally emphasize eating fruits, vegetables, whole grains, beans and legumes, and seafood.”
What’s more, when you adopt the Mediterranean diet, you have the opportunity for exposure to a wider variety of flavors and eating experiences says Michelle Dudash, RDN, Cordon Bleu-certified chef, author of “The Low-Carb Mediterranean Cookbook,” and creator of Spicekick meal spice kits notes
“Glance at a map and you’ll see there are more regions on the Mediterranean, including the Middle East and North Africa,” says Dudash. “This is wonderful because you can discover new foods and enjoy even more food options while expanding your palate.”
Patterns Over Perfection
While all three experts agree that, regardless of ethnic region, the Mediterranean diet relies heavily on produce, legumes, olive oil, seafood, whole grains, herbs, and spices, making it your own does not have to be a process of elimination. Think of making additions to your diet in these categories, and do not wait until your so-called golden years to get on board.

“Starting healthy habits earlier in life is important for keeping health risks low and biomarkers in check,” says Dudash. “For example, arteries don’t become clogged and blood sugars don’t go out of balance overnight from our lifestyle, but rather over a long period of time.”
She notes that prioritizing high-fiber fruits and vegetables, grains, healthy fats (from olive oil, seafood, nuts, and seeds), and lean meats can aid in living a disease-preventative Mediterranean lifestyle.
Amy Myrdal Miller, MS, RDN, culinary nutrition expert and president of Farmer’s Daughter Consulting in Carmichael, California, echoes the importance of prioritizing patterns over specific food groups.
“It’s important to look at dietary patterns over time versus the impact of single foods or individual nutrients,” Mydral Miller says.
She suggests patterns that include abundant fruits, vegetables, legumes, nuts, and other plant-based foods alongside animal-based foods like lean beef and low-fat dairy to promote health as well as enjoyment.
“Enjoyment is key to following an eating pattern that will last versus following a short-term diet,” Myrdal Miller says.
How to Start Eating the Mediterranean Way
Reaping the potential longevity benefits of the Mediterranean diet doesn’t have to mean you’re eating like a Greek fisherman—although, wouldn’t that be nice if it were that easy. Dudash notes that small, sustainable changes to your overall meal plan are best in the long run.
She recommends that you make small changes like adding beans to salads and stirring them into stews and soups. You also can try to have a vegetable on your plate at most meals—even a handful of greens on your sandwich helps. And, while a moderate portion of steak is fine, fill most of your plate with your favorite vegetables.
Another option is to enjoy easy-to-grab fruit, nuts, and seeds for snacks and to get in the habit of using extra-virgin olive more often in place of butter and margarine. For dessert, do as the Italians do by ending with a fresh fruit plate and saving sugary sweets for special occasions.
Overall, Dudash says keeping your kitchen stocked with the Mediterranean diet essentials will help you get meals on the table easier. And don’t forget that canned, frozen, and dried fruits, vegetables, and seafood all count, too.
