Higher Lutein Levels May be Correlated With Greater Physical Activity
Lutein is a carotenoid that can be found in green vegetables and may reduce the risk of some age-related conditions. A recent study suggests that there may be a positive correlation between high levels of lutein intake and increased physical activity.
For this review, the researchers examined studies that looked at the relationship between physical activity and lutein consumption. Seventeen studies met the inclusion criteria. Eleven reported positive associations, three reported mixed results, and three reported no association.
The researchers found that higher lutein levels were associated with higher levels of physical activity. However, it was unclear from this study whether this correlation was due to the fact that people who are more physically active tend to eat healthier or whether lutein has a direct effect on physical activity.
Researchers from the University of South Australia conducted the study. It was published August 29, 2018, in the journal Nutrients.
You can increase your lutein levels by consuming more green vegetables, corn, avocados, and egg yolk. It can also be taken in supplement form.
