Mediterranean Diet Tied to Lower Anxiety and Stress in Older Australians,但 Not Depression
Closer to a Mediterranean diet, less anxiety and stress. Depression didn't move.
Mark
So what did the study actually find?
Mimi
Among 294 Australians aged 60 and over, closer Mediterranean diet adherence went with less anxiety and less stress. Depression showed no link.
Mark
Why would depression be different?
Mimi
The authors say depression has biological, psychological, and social roots, so diet alone is unlikely to shift it.
Luke
That's their explanation, though, not something the study tested. The data shows no association; the why is interpretation.
Mark
The food breakdown seems odd, then. Vegetables were tied to lower depression.
Mimi
Yes. Vegetables went with fewer depression symptoms, fruit with lower stress, nuts with lower anxiety and stress, legumes with lower anxiety.
Luke
Which sits awkwardly beside the overall null result for depression. The report doesn't reconcile that, and with many food comparisons, some patterns can appear by chance.
Mark
Can we say diet reduces anxiety?
Luke
No. This was a one-time online survey, so it shows association, not cause. Anxious people might also eat differently.
Mimi
The authors say as much by asking for prospective studies and clinical trials.
Mark
Anything about who answered?
Luke
Participants were self-selecting online respondents, about two-thirds women, and most reported only mild symptoms. How far this reaches beyond that group is unknown.
Der Puls
- A survey of 294 older Australians found that closer adherence to the Mediterranean diet tracked with lower anxiety and stress, yet depression scores stayed stubbornly flat.
- The authors resist an easy promise, noting that depression draws on biological, psychological, and social roots that no single dietary pattern is likely to untangle.
- Researchers are pressing forward with calls for prospective studies and well-powered clinical trials before anyone prescribes diet as a psychiatric adjunct.
- Early signals are mixed but encouraging: more vegetables linked to fewer depression symptoms, nuts and legumes to calmer anxiety, and less sugary drink to milder symptoms.
In a Nutrients study of 294 community-dwelling Australians aged 60 and over, those who ate more in keeping with the Mediterranean pattern reported less anxiety and stress, while their depressive symptoms appeared unchanged. The result arrives in a long and uneven conversation about whether ordinary daily food choices can ease the inner weather of later life. Because depression seems to be shaped by biology, circumstance, and social life all at once, the researchers suggest a plate alone may not reach it. For now, the finding offers a hopeful but tentative thread linking what we eat with how we feel as we grow older.
A research team in Australia asked 294 older adults, all living independently in the community, to describe what they eat and how they feel. The survey came back with a split result. Those who ate more like a Mediterranean diet reported less anxiety and less stress, but their depression scores did not shift at all. The study was published in the journal Nutrients.
The question behind the work is practical. Diet is something people can change, and the Mediterranean pattern is already well regarded for protecting against chronic disease and supporting healthy aging. Earlier studies linking anti-inflammatory eating to better mood, however, have been inconsistent, and evidence for older adults in particular has been thin. The researchers suspect the mixed picture comes from differences in study design, in how anxiety and depression were measured, and in which age groups were studied.
Most participants showed at least mild symptoms, and men and women did not differ significantly in their scores. Women followed the diet more closely than men. Looking at individual foods told a richer story: more vegetables went with fewer depressive symptoms, more fruit with lower stress, nuts with less anxiety and stress, legumes with less anxiety, and modest intake of sugary drinks with milder anxiety.
The authors read these findings as a reason to treat healthy eating as part of mental health care for older people, but not as a cure. They call for longer, carefully designed studies and clinical trials, especially among those with diagnosed conditions, before diet might take a recognized place alongside standard psychiatric treatment.
A group of researchers in Australia put 75 questions to older adults living independently in the community, and what came back was a split result: people who ate closer to a Mediterranean diet reported less anxiety and less stress. Their depression scores did not budge. The findings were published in the journal Nutrients.
The study looked at adults aged 60 and over. The question behind it is a practical one. Diet can be changed, and the Mediterranean pattern has already been endorsed in research for lowering chronic disease risk and supporting healthy aging. Earlier work has linked anti-inflammatory eating to lower depression in younger and middle-aged adults, but those results have been inconsistent. The authors suggest the inconsistency may come from differences in study design, whether anxiety or depression was measured, how depression was identified, and which age group was examined. For older adults in particular, evidence tying lifestyle habits like diet to mental health remains thin.
The team used an online survey, and 303 people responded. Of those, 294 completed the parts needed for the final analysis: 201 women, 91 men, and two people whose gender was not specified. Mental health was measured with the DASS-21, a screening tool with seven items each for depression, anxiety, and stress, and one that has held up well in older adults in earlier work. Diet was scored with the 14-item MEDAS, in which each question earns a zero or a one and a higher total means closer adherence to the Mediterranean pattern.
The analysis used linear regression and accounted for other factors, including cognitive status, which could confuse the picture. Cognition was assessed with Lawton's instrumental activities of daily living scale and the AD8 dementia screening tool.
Mild symptoms were common. According to the DASS-21, 99 participants reported mild depression symptoms, 80 mild anxiety, and 47 mild stress. Symptom levels did not differ significantly between men and women. Adherence to the Mediterranean diet across the whole sample was moderate, with women following it more closely than men.
The central finding was that better adherence went with less severe anxiety and stress, but showed no relationship to depressive symptoms. The authors point to the nature of depression, which involves biological, psychological, and social risk factors, and say it is unlikely that a healthy dietary pattern alone would ease its symptoms.
Breaking the diet into its parts added detail. Eating more vegetables was associated with fewer depression symptoms, even though the overall diet score was not. More fruit was tied to lower stress. Nut consumption was linked to lower anxiety and stress, and legumes to lower anxiety. Drinking less than 250 mL a day of sugar-sweetened beverages was associated with milder anxiety.
The authors read the results as support for healthy eating as part of addressing mental health problems in older adults. They call for prospective studies and well-powered clinical trials, especially among older people with diagnosed mental health conditions, and for work to explain why results differ across age groups. If that research bears out, they say, Mediterranean-style diets could become an adjunctive treatment in psychiatric practice.
