Potential Role of Diet on Cardiorespiratory Fitness in Heart Failure With Preserved Ejection Fraction

Diet can have detrimental (red arrows) or beneficial (green arrows) effects on cardiorespiratory fitness (CRF). A diet low in monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) and high sugars may contribute to worsening CRF (red arrows). Conversely, a diet rich in MUFAs and PUFAs and low in sugars may exert beneficial effects in patients with heart failure with preserved ejection fraction by increasing CRF through improvements in myocardial relaxation and body composition (green arrows).
