Beijing, October31’2017: If you enjoy eating spicy Chinese food, there are greater chances that you would crave less for salt and have lower blood pressure, potentially reducing the risk of heart attack and stroke, new research suggests.

“Previously, a pilot study found that trace amounts of capsaicin, the chemical that gives chili peppers their pungent smell, enhanced the perception of food being salty,” said senior study author Zhiming Zhu, Professor at the Third Military Medical University in Chongqing, China.

“We wanted to test whether this effect would also reduce salt consumption,” Zhu added.

The study enrolled more than 600 Chinese adults and determined their preferences for salty and spicy flavours. Researchers then linked those preferences to blood pressure.

The findings, published in the journal Hypertension, showed that compared to those who least enjoyed spicy foods, participants with a high spicy preference had lower blood pressure and consumed less salt than participants who had a low spicy preference.

They also used imaging techniques to look at two regions of the participants’ brains — the insula and orbitofrontal cortex — known to be involved in salty taste.

The researchers found that the areas stimulated by salt and spice overlapped, and that spice further increased brain activity in areas activated by salt.

This increased activity likely makes people more sensitive to salt so that they can enjoy food with less of it, the researchers said.

“If you add some spices to your cooking, you can cook food that tastes good without using as much salt,” Zhu said.

“Yes, habit and preference matter when it comes to spicy food, but even a small, gradual increase in spices in your food may have a health benefit,” Zhu said.(IANS)

Suffering From Low Blood Pressure? Do an Hour or More of Daily Exercise

Suffering from low blood pressure? Do an hour or more of daily exercise and stay hydrated to improve the condition and control fainting or dizziness episodes, finds a NASA-funded study on astronauts.

The study is the first to examine the condition called “orthostatic intolerance” during daily activities when the astronauts returned home.

The researchers found that exercise regimens during space flight, followed by saline injections after landing, were sufficient to prevent the condition from occurring.

“Doing an hour or more of daily exercise was sufficient to prevent loss of heart muscle, and when it was combined with receiving hydration on their return, the condition was prevented entirely. We expected to see up to two-thirds of the space crew faint. Instead, no one fainted,” said cardiologist Dr Benjamin Levine from UT Southwestern Medical Center.

A similar condition is also diagnosed in patients as Postural Orthostatic Tachycardia Syndrome (POTS), which is predominantly found in women. The dizziness that it causes is life-changing and can be debilitating.

Dr Levine has helped one Dallas patient return to a normal life.

For the study, published in the journal Circulation, the researchers used a small blood pressure cuff on astronauts’ finger to measure blood pressure and every heartbeat.

These measurements were taken during multiple 24-hour periods before, during, and after six months of spaceflight. Twelve astronauts were involved — eight men and four women.

This treatment is just one of the ways medicine, heart research, and space travel have connected throughout Dr Levine’s work. The successful moon landing in 1969 was an early influence on his career.

The early interest led Dr Levine into space research within the field of cardiology, and he began working with the space shuttle programme in 1991.

“We put a catheter in an astronaut’s heart — it was former UT Southwestern faculty member Dr Drew Gaffney — and sent him into space. It was probably the most expensive right-heart catheterization ever,” Dr Levine reminisced.

“Much of our early research was devoted to understanding why astronauts faint when they return from space. Now, we can prevent it from happening”. (IANS)
