The foods associated with the greatest gains in longevity may not be identical for men and women, according to a large study suggesting that healthy eating can follow a common foundation while still benefiting from more individualized dietary priorities.
Researchers analyzing data from more than 100,000 people in the United Kingdom found that adherence to several established healthy dietary patterns was associated with lower mortality and greater life expectancy over more than a decade of follow-up.
But the dietary pattern linked to the largest estimated gain differed between men and women.
For women, the strongest association was found with the Alternate Mediterranean Diet, or AMED, a Mediterranean-style eating pattern that places substantial emphasis on whole grains.
A 45-year-old woman closely following that pattern could potentially gain approximately 2.3 years of life expectancy, according to the analysis.
For men, the Diabetes Risk Reduction Diet, or DRRD, produced the largest estimated benefit. A 45-year-old man with strong adherence to that dietary pattern could potentially gain about three years of life expectancy.
The DRRD emphasizes foods associated with better metabolic health, including coffee, while strongly discouraging sugar-sweetened beverages.
The findings came from researchers at Queen Mary University of London and Tongji Medical College in China and were published in Science Advances.
The study compared five established healthy dietary patterns and followed participants for a median period exceeding 10 years.
Researchers found that greater adherence to any of the healthy eating patterns was associated with longer life.
The differences appeared in the magnitude of the estimated benefit and in which pattern showed the strongest association for men compared with women.
That does not mean there are two completely different sets of healthy foods.
Across the dietary patterns, researchers found substantial common ground.
Fruits, vegetables, nuts and healthier sources of fat were consistently emphasized, while red and processed meats were generally limited.
Higher consumption of plant foods was repeatedly associated with lower mortality, reinforcing a broader body of research linking plant-forward diets with reduced risks of cardiovascular disease, diabetes, cancer and premature death.
The study’s distinguishing finding was that certain components within that broadly healthy framework appeared to carry different importance for men and women.
For Women, Whole Grains Stand Out
The Alternate Mediterranean Diet was associated with the greatest estimated longevity benefit among women.
Like other Mediterranean-style eating patterns, AMED emphasizes fruits, vegetables, nuts and healthy fats such as olive oil while limiting red and processed meat.
Whole grains are particularly important within the pattern.
Foods such as oats, quinoa, brown rice and whole-grain bread provide dietary fiber along with vitamins, minerals and numerous plant compounds.
Fiber supports digestive health, contributes to better blood-glucose regulation and can increase satiety, potentially helping with weight management.
Whole grains have also been repeatedly associated with improved cardiovascular and metabolic health.
Researchers suggested that biological differences between men and women, including hormonal and metabolic differences, could help explain why particular dietary components produce different associations with longevity.
The study does not establish that whole grains themselves account for the entire advantage observed among women.
Rather, the results point to the complete Alternate Mediterranean Diet as the dietary pattern associated with the largest estimated improvement.
That distinction matters because nutrition studies frequently find that combinations of foods and nutrients may be more informative than isolating a single ingredient.
The Mediterranean approach brings together fiber-rich grains, plant foods and unsaturated fats while reducing consumption of several foods associated with poorer metabolic and cardiovascular outcomes.
The findings therefore support the larger concept of dietary patterns rather than presenting quinoa, brown rice or another individual whole grain as a stand-alone longevity treatment.
Coffee and Sugar-Sweetened Drinks Matter for Men
The strongest association among men was found with the Diabetes Risk Reduction Diet.
The DRRD was developed around foods and dietary behaviors associated with a reduced risk of Type 2 diabetes.
One of its more distinctive components is coffee.
Previous research associated with the dietary pattern has suggested benefits from consuming at least two cups daily, although individual tolerance and health circumstances can vary.
Coffee contains numerous biologically active compounds that researchers have studied for their potential effects on inflammation, glucose metabolism and insulin sensitivity.
At the same time, the DRRD strongly penalizes consumption of sugar-sweetened beverages.
That combination — encouraging coffee while discouraging sugary drinks — places blood-sugar regulation at the center of the eating pattern.
In the study, heavy consumption of sugary beverages was associated with a 7% higher mortality risk, among the larger adverse associations identified.
Sugar-sweetened sodas, sweetened juices and similar drinks can deliver substantial quantities of rapidly absorbed sugar without the fiber present in whole fruit.
Regular high consumption has been associated in other research with weight gain, insulin resistance and Type 2 diabetes.
Because diabetes can contribute to cardiovascular disease, kidney disease and other serious complications, a dietary pattern designed to improve metabolic health could have effects extending beyond diabetes itself.
The estimated longevity benefit was substantial.
Among 45-year-old men, strong adherence to the DRRD was associated with approximately three additional years of life expectancy.
As with the findings for women, however, the result is an association rather than proof that adopting the diet will automatically add a specific number of years to an individual’s life.
The estimates are population-level projections based on observed dietary patterns and mortality outcomes.
Plants Form the Common Foundation
Despite the differences between the leading diets for men and women, the study found a remarkably consistent nutritional foundation across all five eating patterns examined.
Greater consumption of fruits and vegetables was associated with lower risk of premature death.
Nuts and healthier fats were also characteristic of the more favorable patterns.
Foods associated with less favorable outcomes included processed meats, sweets and desserts, along with higher consumption of potatoes in the dietary scoring systems examined.
The results reinforce a broader nutritional principle that extends beyond any individual named diet: minimally processed plant foods tend to dominate eating patterns associated with better long-term health.
That is also consistent with research surrounding the so-called planetary health diet, which emphasizes plant foods while reducing reliance on red and processed meat.
Models evaluating that approach have associated it with lower rates of premature death and chronic illnesses including cardiovascular disease, diabetes and cancer.
Genetics Did Not Erase the Diet Association
Researchers also examined whether inherited genetic risk fundamentally altered the relationship between healthy diets and longevity.
The associations remained even after genetic factors were taken into consideration.
Participants following healthier dietary patterns showed estimated longevity benefits regardless of genetic inheritance.
That finding does not mean diet can eliminate every genetically influenced health risk.
It does suggest that inherited predisposition does not make healthy dietary choices irrelevant.
Lifestyle and genetics can operate simultaneously, with food, exercise, smoking, sleep and other behaviors potentially influencing health outcomes even when a person carries inherited susceptibility to disease.
The finding adds to evidence that longevity is not dictated exclusively by genes.
Personalization Without Abandoning the Basics
The study’s results complicate the search for a single supposedly ideal diet.
Rather than identifying one eating plan that clearly outperformed every other option for everyone, the researchers found that multiple healthy dietary patterns were associated with longer life.
The strongest association simply differed between men and women.
For women, that may mean placing additional emphasis on whole grains within a Mediterranean-style dietary framework.
For men, maintaining strong metabolic health by avoiding sugary beverages while incorporating foods associated with lower diabetes risk — including coffee for people who tolerate it — may deserve greater attention.
Those differences sit within an otherwise highly similar nutritional foundation.
Neither leading dietary pattern revolves around highly processed foods, excessive sugar or large amounts of processed meat.
Both prioritize nutrient-dense whole foods.
The findings therefore support personalization without abandoning established nutritional principles.
“A diet is a self-created plan of action to modify behavior and attitude toward food. It involves setting boundaries on an existing eating style that isn’t producing desired results,” said BrightU.AI’s Enoch. “Ultimately, the specific limits and choices within a diet are personal decisions made during the process.”
That individualization can also account for health conditions, medications, allergies, food preferences and cultural eating habits.
Coffee, for example, may fit the dietary pattern associated with longevity among men in the study, but that does not mean everyone should substantially increase caffeine consumption. Some people experience insomnia, anxiety, heart palpitations or other unwanted effects from caffeine.
Likewise, whole grains can be an important part of a healthy eating pattern without requiring everyone to consume the same grains or quantities.
The larger finding is that food choices appear capable of influencing long-term health even when individual biology differs.
For a 45-year-old woman, adherence to the Alternate Mediterranean Diet was associated with as much as 2.3 additional years of expected life.
For a man of the same age, the Diabetes Risk Reduction Diet was associated with an estimated gain of three years.
Those numbers should not be read as guaranteed extensions of an individual’s lifespan. The study is observational and cannot prove that a particular diet directly caused participants to live longer, while factors associated with healthier eating may also contribute to the observed results.
What the findings do provide is additional evidence that long-term dietary patterns matter.
The strongest diets may differ somewhat between men and women, but their similarities remain greater than their differences: more fruits, vegetables, nuts, whole foods and healthier fats, with fewer processed meats, sweets and sugar-heavy beverages.
Rather than revealing separate nutritional universes for men and women, the research points toward a shared healthy foundation with room for more targeted choices within it.
