KATHMANDU — People consuming nuts and seeds have a lower risk of heart disease than those mostly eating meat, according to a study conducted in the United States and France.
Researchers from Loma Linda University School in California, and AgroParisTech and the Institute of National Agronomic Research in Paris, have found that meat protein is associated with a sharp increased risk of heart disease while protein from nuts and seeds is beneficial for the human heart.
Red meat increases heart disease risk by 60 percent while food proteins — nuts and seeds — cause a 40 percent reduction to risk, the findings published this week in the International Journal of Epidemiology said.
“While dietary fats are part of the story in affecting risk of cardiovascular disease, proteins may also have important and largely overlooked independent effects on risk,” said Dr. Gary Fraser, from Loma Linda’s School of Public Health in a press release.
“This new evidence suggests that the full picture probably also involves the biological effects of proteins in these foods.”
The study examined 81,337 Seventh-day Adventists, a group that is about evenly split between vegetarians and meat-eaters, from 2002 to 2007. The men and women, between age 25 and 44, were asked what kinds of food they eat on a regular basis, including the amount of meat, nuts, grains and veggies.
“A wide variety of nuts, eaten in small quantities each day, will lower blood LDL cholesterol — the bad cholesterol,” Fraser told Business Insider. The difference, he said, is 10 to 14 mixed nuts a day.
The researchers during the nine-year followup period, closely examined what the participants ate, as well as details of 2,276 deaths among participants credited to cardiovascular causes.
Fraser said that nutritionists considered ‘bad fats’ in meats and ‘helpful fats’ in nuts and seeds, and said the researchers had always suspected it made a difference what kind of protein people consumed.
The researchers, however, didn’t just examine the differences between animal and plant proteins, they also looked at other dietary sources, they said. The researchers found no significant associations for grains, processed foods, legumes, fruit and vegetables among protein factors.
“Associations between the ‘meat’ and ‘nuts and seeds’ protein factors and cardiovascular outcomes were strong and could not be ascribed to other associated nutrients considered to be important for cardiovascular health,” the researchers wrote in the study.Follow @gorkhapost
Regular bedtime beneficial for heart and metabolic health among older adults
KATHMANDU — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But a new study on sleep patterns has suggested that a regular bedtime and wake time are just as important for heart and metabolic health among older adults too.
Researchers at Duke Health and the Duke Clinical Research Institute, in a study of 1,978 older adults, have found that people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.
The study was published Sept 21 in the journal Scientific Reports.
“From our study, we can’t conclude that sleep irregularity results in health risks, or whether health conditions affect sleep,” said study’s lead author Jessica Lunsford-Avery.
“Perhaps all of these things are impacting each other.”
African-Americans had the most irregular sleep patterns compared to participants who were white, Chinese-American or Hispanic, the data showed.
Still, the data suggest tracking sleep regularity could help identify people at risk of disease, and where health disparities may impact specific groups.
Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.Follow @gorkhapost
