Older adults who followed an anti-inflammatory eating pattern and stayed physically active had markedly lower odds of dying during a seven-year follow-up than peers who did neither.
That is the finding of a prospective cohort study published in August 2026 in Frontiers in Immunology.
The researchers tracked 6,468 participants aged 65 and older in the Chinese Longitudinal Healthy Longevity Survey from 2011 through 2018. During follow-up, 4,117 died.
Combining a high score on the Anti-Inflammatory Diet Index with regular exercise was linked to a 27 percent lower risk of death .

Pairing the same diet with active leisure pursuits went further, cutting the risk by 39 percent.
Physical labor on its own did not add a significant survival benefit.
What the researchers counted as anti-inflammatory eating
The team's index scored ten food groups commonly eaten by older Chinese adults, among them fish, nuts, eggs, dairy, soy foods, mushrooms and algae, tea, garlic and medicinal plants.
That list overlaps only partly with the Mediterranean-style pattern that dominates US nutrition guidance, but the principle is the same.

Harvard Health describes the anti-inflammatory template as heavy on fruits and vegetables, whole grains, legumes, nuts and seeds, fish and olive oil, with red meat, sweets, sugary drinks and highly processed foods kept to a minimum.
That eating style has been tied to lower rates of cardiovascular disease, metabolic syndrome and type 2 diabetes.
Why the combination may do more than either alone
The authors write that the protective effects may be partly explained by modulation of gut microbiota composition, mitigation of chronic inflammation and reduction of oxidative stress.
Regular movement layers on top, improving insulin sensitivity and dampening the low-grade inflammation that tends to build with age, a state researchers call inflammaging.

Together, the two habits may compound their protective effect on cardiovascular and metabolic health.
The benefit was not uniform. The inverse link between the diet and mortality held for participants of normal weight, but did not reach statistical significance in those who were underweight or obese.
It was strongest among women, rural residents, non-smokers and adults aged 80 and older.
What it means in practice
Because this was an observational study, it cannot prove that either habit directly caused the lower death rate. Still, the direction of the finding lines up with what US public health authorities already advise.

The CDC recommends that adults 65 and older log at least 150 minutes of moderate-intensity aerobic activity each week, add two days of muscle-strengthening exercise and include regular balance work, such as heel-to-toe walking or standing up from a chair without using the hands.
Older adults with chronic conditions, or who have not exercised in some time, should talk with a doctor before making a large change to their diet or activity level.
