According to research reviewed by Gram, older adults who eat anti-inflammatory foods have significantly better heart and lung fitness. A cross-sectional study of Chinese community-dwelling older adults found that those eating the least inflammatory diet had 81% higher odds of excellent fitness levels compared to those eating the most inflammatory diet. Benefits were even stronger for physically active individuals, and people who switched to anti-inflammatory diets showed three times higher odds of excellent fitness.
A new study of Chinese older adults found that people who eat foods that reduce inflammation in the body have better heart and lung fitness. Researchers measured inflammation levels in participants’ diets and tested their cardiovascular fitness using exercise bikes. Those who ate the most anti-inflammatory foods had significantly better fitness levels than those eating the most inflammatory foods. The benefits were even stronger for people who also exercised regularly. The findings suggest that choosing anti-inflammatory foods, especially combined with physical activity, may help older adults maintain better heart health as they age.
Key Statistics
A cross-sectional analysis of Chinese community-dwelling older adults found that those eating the least inflammatory diet had 81% higher odds of excellent heart and lung fitness compared to those eating the most inflammatory diet.
According to a 2026 study in the British Journal of Nutrition, older adults who switched from a high-inflammatory diet to a low-inflammatory diet had three times higher odds of achieving excellent cardiorespiratory fitness.
Research shows that the connection between anti-inflammatory diets and better fitness was significantly stronger among physically active older adults, suggesting diet and exercise work synergistically for fitness benefits.
A study of older adults found that consistent adherence to a low-inflammatory diet was associated with 2.5 times higher odds of excellent cardiorespiratory fitness compared to maintaining a high-inflammatory diet.
The Quick Take
- What they studied: Whether eating foods that reduce inflammation in the body is connected to better heart and lung fitness in older adults living in their communities.
- Who participated: Chinese older adults living in the community who participated in the Guangzhou Nutrition and Health Study between 2017 and 2021. Researchers collected information about their diets and tested their fitness levels.
- Key finding: Older adults who ate the most anti-inflammatory foods had 81% higher odds of having excellent heart fitness compared to those eating the most inflammatory foods. The connection was even stronger for people who were physically active.
- What it means for you: Choosing foods that fight inflammation, like fruits, vegetables, and whole grains, may help you maintain better heart and lung fitness as you age. This benefit appears to work best when combined with regular exercise. However, this study shows a connection, not proof that diet changes will definitely improve fitness.
The Research Details
This was a cross-sectional study, which means researchers looked at information from people at one point in time rather than following them over years. Researchers used data from two visits to the Guangzhou Nutrition and Health Study between 2017 and 2021. They asked participants detailed questions about what they ate using a 79-item food questionnaire, then calculated a score showing how inflammatory their diet was. The researchers then tested each person’s heart and lung fitness using a stationary bike with a special protocol designed for older adults. They measured how much oxygen people could use during exercise and compared this to what would be expected for their age and sex.
This research approach is important because it looks at real people living in their communities rather than in controlled lab settings. The detailed food questionnaire captures a complete picture of what people actually eat, and the fitness testing uses a safe method designed specifically for older adults. By examining both diet and fitness at the same time, researchers could identify connections between eating patterns and physical health that might help guide recommendations for healthy aging.
The study used validated tools, meaning the food questionnaire and fitness tests have been proven reliable in previous research. The researchers adjusted their analysis for other factors that affect fitness, like age, sex, and physical activity level. However, because this is a cross-sectional study, it shows connections between diet and fitness but cannot prove that changing your diet will improve your fitness. The study included only Chinese community-dwelling older adults, so results may not apply equally to other populations.
What the Results Show
Older adults who ate the least inflammatory diet had significantly better heart and lung fitness than those eating the most inflammatory diet. Specifically, people in the lowest inflammatory diet group had 81% higher odds of having excellent fitness levels, measured as oxygen use during exercise. This connection was statistically significant, meaning it was unlikely to happen by chance. The benefit was particularly strong among people who were physically active, suggesting that diet and exercise work together to support fitness. When researchers looked at people who switched from a high-inflammatory diet to a low-inflammatory diet, those people had three times higher odds of excellent fitness compared to people who stayed on a high-inflammatory diet throughout the study period.
The study also looked at another fitness measure called heart rate response during exercise, but found no significant connection to diet inflammation levels. This suggests that the anti-inflammatory diet’s benefits for fitness may work through specific pathways related to oxygen use rather than affecting all aspects of fitness equally. Interestingly, people who consistently followed a low-inflammatory diet throughout the study had 2.5 times higher odds of excellent fitness, showing that maintaining these eating habits over time may be important for sustained benefits.
This research adds to growing evidence that what we eat affects our heart and lung health as we age. Previous studies have shown that inflammatory foods are linked to heart disease and poor health outcomes in older adults. This study is one of the first to directly connect dietary inflammation scores to measured fitness levels in community-dwelling older adults. The findings align with recommendations from nutrition experts that anti-inflammatory diets support healthy aging, though this study provides new evidence specific to fitness outcomes.
This study shows connections between diet and fitness but cannot prove that changing your diet will improve your fitness, since it captured information at one point in time rather than following people over years. The study included only Chinese older adults living in communities, so results may not apply equally to other ethnic groups or people in different settings. The researchers relied on people’s memory of what they ate, which can be inaccurate. The study did not include information about all factors that might affect fitness, such as sleep quality or stress levels.
The Bottom Line
Gram Research analysis suggests that older adults should consider eating more anti-inflammatory foods like fruits, vegetables, whole grains, and fish while reducing inflammatory foods like processed items and sugary foods. This dietary approach appears most effective when combined with regular physical activity. The evidence is moderately strong for this recommendation based on this cross-sectional study, though more research following people over time would provide stronger proof. Consult with a healthcare provider before making major dietary changes, especially if you have existing health conditions.
This research is most relevant to older adults interested in maintaining or improving their heart and lung fitness. It may be particularly valuable for people who are already physically active or considering starting an exercise program. The findings apply to community-dwelling older adults and may be less relevant to people with serious health conditions or those in care facilities. Younger adults may also benefit from these dietary patterns, though this study specifically examined older populations.
Changes in fitness from dietary improvements typically take weeks to months to become noticeable. The strongest benefits in this study appeared in people who maintained anti-inflammatory eating habits over time, suggesting that consistency matters more than quick changes. You might expect to see improvements in energy levels and exercise tolerance within 4 to 8 weeks of consistently eating anti-inflammatory foods, especially if combined with regular physical activity.
