- A Harvard study has linked high BP to consumption of well-cooked meats.
- Roasting, broiling and grilling were highlighted as 3 main culprits.
- High temperature cooking releases a chemical that may up your BP.
The study showed that people who grilled, roasted or broiled their chicken, beef or fish more than 15 times a month, had 17 per cent more chances of having high blood pressure than those who restricted their well-cooked meat intake to less than four times a month. Overall, for people who preferred their meals well-done, the risk was 15 per cent higher than for those who preferred to eat rarer meats. The reason behind this was the fact that High-temperature cooking releases chemicals that may raise your blood pressure levels.
Increased blood pressure is often a precursor to many cardiovascular diseases. The study looked at the cooking methods of 103,941 men and women, who regularly ate chicken, beef and fish and analysed the development of high blood pressure in their bodies. Lead author of the study, Gang Liu, who is a postdoctoral research student at the Harvard T.H. Chan School of Public Health in Boston said, "The chemicals produced by cooking meats at high temperatures induce oxidative stress, inflammation and insulin resistance in animal studies, and these pathways may also lead to an elevated risk of developing high blood pressure."
Atherosclerosis or hardening of arterial walls is the underlying process for a lot of heart diseases and its causes include oxidative stress, insulin resistance and inflammation. Liu said: "Our findings suggest that it may help reduce the risk of high blood pressure if you don't eat these foods cooked well done and avoid the use of open-flame and/or high-temperature cooking methods, including grilling/barbequing and broiling." The study is still a preliminary one since it hasn't been published in any peer-reviewed journal yet and hence, must be taken with a pinch of salt.
