This study looked at how the food we eat and our fitness level are related. The researchers studied a large group of people and measured their fitness using a test that measures how well their heart and lungs work during exercise. They also asked the participants about their eating habits using a questionnaire.
The researchers found that people who had healthier diets had better fitness levels. Specifically, for every improvement in diet quality, the participants had a 5.2% higher fitness level. They also looked at the chemicals in the participants' blood and found some that were related to both diet and fitness. Some chemicals were linked to lower fitness and poorer diets, while others were linked to higher fitness and healthier diets. These findings suggest that eating a healthy diet can improve fitness and overall health.
