“You are what you eat.” OK. A cliché simple for its brevity and truthiness. It also makes sense. Here’s another: “You are what your body does with what you eat.”
Legion are the studies focused on diet—weight loss explorations, food pyramid rebuilds, energy-hyping food investigations, and more. A recent take shared in Nature Medicine and titled “Optimal dietary patterns for healthy aging” digs into and unpacks the crucial role of diet in promoting healthy aging.
And why not? As our global population continues to live longer and grow older, understanding how our food choices impact long-term health is a no-brainer. The research, extensive in its methodology, offers valuable insights into dietary patterns that may help you live longer while maintaining better cognitive, physical, and mental health as you age.
The study followed more than 100,000 participants for up to 30 years, exploring the relationship between different dietary patterns and what the authors referred to as “healthy aging,” which they defined as “surviving to the age of 70 years without the presence of 11 major chronic diseases and with no impairment in cognitive function, physical function or mental health.”
The study’s findings provide compelling evidence for the power of dietary choices in shaping your later years for the better.

Say what?
The research evaluated eight different dietary patterns, such as the Alternative Healthy Eating Index (AHEI), Alternative Mediterranean Diet (aMED), Dietary Approaches to Stop Hypertension (DASH), and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, among others. What was revealed in the investigation should come as no real surprise: Participants who adhered more closely to these healthy dietary patterns had significantly higher odds of achieving healthy aging. For instance, those with the highest adherence to the AHEI had 86% greater odds of healthy aging when compared to those with the lowest dietary adherence.
Eat what?
Plant-based diets were demonstrated by researchers as particularly beneficial. The evaluations of the healthful plant-based diet index (hPDI) and the Planetary Health Diet Index (PHDI) were both associated with better odds of healthy aging. The takeaway here is noteworthy, but, again, not shocking: Diets rich in fruits, vegetables, whole grains, and plant-based proteins may contribute significantly to overall health and longevity.

The study identified several food groups that were particularly beneficial for healthy aging. Higher intakes included, as noted above, fruits (especially berries), vegetables (particularly leafy greens and dark yellow vegetables), and whole grains. Nuts, legumes, and low-fat dairy products were all associated with greater odds of healthy aging. Conversely, higher intakes of red and processed meats, trans fats, sodium, and sugary beverages were linked to lower odds of healthy aging.
Ultra-processed foods emerged as a significant concern. The research found that higher consumption of these foods was associated with 32% lower odds of healthy aging. The takeaway here is the importance of choosing whole, minimally processed foods as part of a healthy diet, a principle that aligns with many current dietary guidelines.
The findings underscore the importance of not just what we eat, but also what we avoid in our diets. And, not for nothing, those foods identified as beneficial to healthy aging—for example, those that are not very spicy, highly processed, acidic or fatty—are easily digestible, which is important for the absorption of nutrients, energy production, healthy immune system function, the elimination of waste, and overall well-being.
In other words, it’s not only what you eat, but what your body does with what you eat.
Mind games, risk factors and subgroups
The beneficial effects of healthy dietary patterns were observed across multiple domains of health, including cognitive function, physical health, and mental well-being. The results of the layered study suggest that a healthy diet can positively impact your aging, allowing for better maintenance and potential improvement of quality of life as you age.
Demographics, if you will, came into play in the study for reasons of exploring associations among subgroups. Included in the groupings were stratifications according to sex, ancestry, socioeconomic status, and lifestyle factors. Researchers found that the strength of associations between dietary patterns and healthy aging varied among these different subgroups. For example, this head-scratcher: The benefits of healthy diets were more pronounced in smokers and individuals with higher body mass index (BMI), despite their lifestyle habits. This highlights the potential for personalized dietary recommendations based on individual risk factors, opening up possibilities for more targeted nutritional interventions.
Conclusion
Globally speaking, the complex health risks faced by older adults are real—real enough that the promotion of healthy aging is a worldwide commitment. In fact, as noted by the study, and backed by the U.S. Office of Disease Prevention and Health Promotion, it is “driven by the goal of promoting a high quality of life, supporting continued contribution to society and reducing healthcare costs.”
Locally, in our own backyard, in our own kitchen, diet is a leading behavioral risk factor impacting mortality. Diet is but a single—although critical—factor in healthy aging. The study detailed by Nature Medicine in March underscores its undeniable impact. By making informed and better food choices, you are taking important and proactive steps toward extending your lifespan and improving the quality of your later years.
The battle on aging is done with forethought. It is a strategic endeavor that is winnable when armed with information. As shared above, become familiar with those food sources that promote good health and can lead to a longer life. Adhere to a healthy diet for the long run, not for the here and now. Make healthy lifestyle decisions, including physical activity levels, tobacco use and BMI.
As always, consult with your healthcare team when considering significant changes to your dietary choices, exercise routines, and other factors that can impact your health—for better or for worse.
Then, go ahead, be what you eat.
