What did studies of healthy eating find?

Studies of healthy eating measured 2 outcomes: gait speed and cardiorespiratory endurance.

Gait speed

upin humans1

1 study

Healthy eating improves gait speed in humans across dietary adherence clusters.
“Significant cluster effects were observed in GS (pclusters = 0.034) and TMS (pclusters = 0.010).”

Cardiorespiratory endurance

upin humans1

1 study

Healthy eating improves cardiorespiratory endurance in humans (higher dietary intervention compliance).
“After adjusting for covariates, significant interaction effects between higher dietary intervention compliance and time were observed in TMS (pinteraction = 0.009) and MMSE (pinteraction = 0.022).”

What is healthy eating linked with?

Studies link healthy eating with number of illnesses.

Number of illnesses

downin humans1

1 study

Healthy eating is associated with number of illnesses in humans (B=-0.12, p< 0.001).
“Greater adherence to not eating fast food was associated with fewer illnesses (B=-0.12; SE=0.03; p< 0.001) but not PWB.”
