Genetics make certain compounds taste bitter, which may make it harder for some people to add heart-healthy vegetables to their diet, according to a new study.

“Your genetics affect the way you taste, and taste is an important factor in food choice,” said study author Jennifer L. Smith from University of Kentucky.

According to the researchers, everyone inherits two copies of a taste gene called “TAS2R38”. People who inherit two copies of the variant called AVI aren’t sensitive to bitter tastes from certain chemicals.

Those with one copy of AVI and another called PAV perceive bitter tastes of these chemicals, however, individuals with two copies of PAV, often called ‘super-tasters,’ find the same foods exceptionally bitter.

“We’re talking a ruin-your-day level of bitter when they tasted the test compound. These people are likely to find broccoli, brussels sprouts and cabbage unpleasantly bitter; and they may also react negatively to dark chocolate, coffee and sometimes beer,” Smith said.

For the study, researchers analysed food-frequency questionnaires from 175 people (average age 52, more than 70 per cent female) and found that people with the PAV form of the gene were more than two and a half times as likely to rank in the bottom half of participants on the number of vegetables eaten.

Bitter-tasting status did not influence how much salt, fat or sugar the participants ate.

“We thought they might take in more sugar and salt as flavour enhancers to offset the bitter taste of other foods, but that wasn’t the case,” Smith said.

“Down the road we hope we can use genetic information to figure out which vegetables people may be better able to accept and to find out which spices appeal to supertasters so we can make it easier for them to eat more vegetables,” Smith added.

Women Who Consume Food Late in The Evening Likely to Suffer Heart Disease: Study

Data from the food diary completed by each woman was used to determine the relationship between heart health and the timing of when they ate

Women who consume a higher proportion of their daily calories late in the evening are more likely to be at risk of Heart Disease than women who do not, researchers have warned.

For the study, the research team assessed the cardiovascular health of 112 women using the American Heart Association’s Life’s Simple 7 measures at the beginning of the study and one year later.

Life’s Simple 7 represents the risk factors that people can improve through lifestyle changes to help achieve ideal cardiovascular health and include not smoking, being physically active, eating healthy foods and controlling body weight, along with measuring cholesterol, blood pressure and blood sugar levels.

A heart health score based on meeting the Life’s Simple 7 was computed.

“The preliminary results indicate that intentional eating that is mindful of the timing and proportion of calories in evening meals may represent a simple, modifiable behaviour that can help lower heart disease risk,” said study lead author Nour Makarem from Columbia University in the US.

During the study, participants of the study kept electronic food diaries by computer or cell phone to report what, how much and when they ate for one week at the beginning of the study and for one week 12 months later.

Data from the food diary completed by each woman was used to determine the relationship between heart health and the timing of when they ate.

Researchers found that, after 6 p.m. with every one per cent calories consumed heart health declined, especially for women.

These women were found more likely to have higher blood pressure, higher body mass index and poorer long-term control of blood sugar.

Similar findings occurred with every one per cent increase in calories consumed after 8 p.m.

“It is never too early to start thinking about your heart health whether you’re 20 or 30 or 40 or moving into the 60s and 70s. If you’re healthy now or if you have heart disease, you can always do more. That goes along with being heart smart and heart healthy,” said study researcher Kristin Newby, Professor at Duke University. (IANS)
