Regular physical activity and healthy eating promote health and longevity plays an important role. Some people think that the effects of a poor diet can be counteracted by high levels of exercise, or the effects of low levels of exercise can be counteracted by a high-quality diet, is that true?
That’s not true —
A new study led by the University of Sydney found thathigh levels of physical activity did not offset the harmful effects of poor diets on the risk of death, with participants with high levels of physical activity and high quality diets having the lowest risk of death.
Using a large sample of UK adults (360,600 people) from the UK Biobank, researchers in the British Journal of Sports Medicine today examined the independent and combined associations of diet and physical activity with all-cause cardiovascular disease and cancer mortality. influences.
What is a high-quality diet?
A high-quality diet includes at least 5 servings of fruits and vegetables per day, 2 servings of fish per week, and less red meat, especially processed meat.

Studies show that people who regularly engage in high levels of physical activity and eat a high-quality diet have a reduced risk of death from all causes, compared to those who eat poorly and lack exercise 17%, a 19% lower risk of death from cardiovascular disease, and a 27% lower risk of death from certain cancers.
Joe Van Buskirk, co-author from the School of Public Health, School of Medicine and Health, University of Sydney, said: Physical activity is important to optimally reduce the risk of death from all causes, cardiovascular disease and cancer.”
There have been few Studies have found that high-intensity exercise may counteract the harmful physiological effects of overeating. However, the long-term effects of the interaction of diet and physical activity remain less explored. The results of this study confirm the importance of physical activity and a high-quality diet in all-cause and cause-specific mortality.
The study’s lead author, Melody Ding, associate professor at the University of Sydney’s Charles Perkins Centre and School of Medicine and Health, said, “This study highlights The importance of physical activity and diet quality in minimizing the risk of death. Public health information and clinical recommendations should focus on promoting physical activity and dietary guidelines to promote healthy longevity.”
