Cardiovascular disease is one of the leading causes of death worldwide. Central obesity, dyslipidemia, and hypertension increase CVD risk. Moreover, vascular function measures are independent risk markers for CVD. The consumption of red meat is associated with CVD risk due to high levels of heme iron, cholesterol, and saturated fatty acids .
About the study In the present study, researchers examined the impact of LFB/HFB consumption on vascular function in males. Participants were recruited in October and November 2019, and ground beef treatments began in February 2020. Data presented here were collected from a sub-sample of a more extensive study. Participants were instructed not to change their habitual diet or physical activity.
Oxygen uptake was examined pre- and post-intervention to account for confounders altering vascular measures. It was measured during an incremental graded exercise test on a treadmill using a metabolic gas analysis system. Maximal VO2 was calculated using an individualized linear regression based on VO2 and heart rate.
SBP was not significantly different between the HFB intervention and washout period. A significant condition effect was observed for resting diastolic BP , which was lower during HFB intervention than baseline or washout period levels. The mean arterial pressure was significantly reduced after HFB intervention and in the washout period relative to the baseline.
