Scientists from the University of Texas found that the effect of minced meat on the work of blood vessels depends little on the fat content in it. Research published in the journal nutrients.
Previous studies have shown that excessive consumption of red meat is associated with an increased risk of cardiovascular disease. At the same time, the highest risk is observed when consuming processed meat – sausages, sausages, smoked meat and other products. The authors noted that some studies have shown no or negligible association between cardiovascular risk and unprocessed meat consumption when red meat consumption is at recommended levels.
In a recent study, researchers evaluated the effects of high-fat (25%) and low-fat (5%) unprocessed red meat on vascular function in men. In total, the analysis included data from 23 men with an average age of 39.9 years. Participants were asked not to change their normal diet or physical activity.
For five weeks, participants ate five ground beef patties per week. At the same time, some participants ate ground beef with a high fat content at first, while others ate low. After that, they ate as usual for four weeks and then switched places.
Vascular function and oxygen uptake during training were assessed during the last week of each period. Before the start of the experiment, there was no difference in parameters.
Dietary intervention did not affect participants’ vascular function or exercise endurance. Also, men who consume high-fat ground beef have lower blood pressure, contradicting the notion that foods high in saturated fat are unhealthy.
Scientists suggest that unprocessed red meat in moderation can be part of a healthy diet. However, their study had limitations: the sample was small and all participants were male. The study’s findings need to be confirmed by larger studies.
