The analysis indicates the Mediterranean diet, which mainly features plant-based foods, like "fruits and vegetables, whole grains, legumes, and nuts," can help keep people strong and healthy in later parts of their lives.
Older adults often show signs of frailty, and individuals are at high risk as they age. Most of the time, these "frail" older individuals can be negatively affected by symptoms such as low energy, weight loss, and weak muscle strength.
These symptoms can then cause serious health concerns like "falls, fractures, hospitalization, nursing home placement, disability, dementia, and premature death." Among older adults, frailty is usually linked to a lower quality of life.
It is believed that nutrition can significantly impact the development of frailty. Dr. Kate Walters, along with Dr. Gotaro Kojima, from University College London, and their colleagues, set out to determine if observing a healthy diet can significantly minimize an individual's risk of frailty.
For this study, the scientists examined data gleaned from published studies that looked into the possible connections between "adherence to a Mediterranean diet and development of frailty in older individuals." The analysis took into account 5,789 people in four studies from China, France, Italy, and Spain.
Dr. Walters shares that they have uncovered evidence which showed that older adults who observed a Mediterranean diet "had a lower risk of becoming frail." She continued, "People who followed a Mediterranean diet the most were overall less than half as likely to become frail over a nearly four-year period compared with those who followed it the least."

The researchers wrote that based on their findings, the diet could also help older individuals preserve their "muscle strength, activity, weight, and energy levels." Dr. Kojima comments that their analysis backs the growing body of evidence which confirms the possible health benefits of a Mediterranean diet. He added that for their study, it was confirmed that the diet could help older adults stay healthy as they grow older.
While older individuals who followed the Mediterranean diet had a lower chance of becoming frail, it remains to be seen if the people who observed the diet had "other characteristics" that may have contributed to this.
Dr. Walters shared, "While the studies we included adjusted for many of the major factors that could be associated -- for example, their age, gender, social class, smoking, alcohol, how much they exercised, and how many health conditions they had -- there may be other factors that were not measured and we could not account for." She concludes that she and the rest of her team need to look into larger studies to determine if "increasing how much you follow a Mediterranean diet will reduce your risk of becoming frail."
