NEW YORK — Consuming higher amount of red or processed meat may increase the risk of developing non-alcoholic fatty liver disease (NAFLD), researchers have warned.
“NAFLD is considered as the hepatic component of the metabolic syndrome, with insulin resistance and inflammation as key factors in its pathophysiology,” said lead author Shira Zelber-Sagi, Professor at the University of Haifa in Israel.
Researchers noted that high meat eaters were slightly younger, mainly male, had a higher body mass index (BMI), caloric intake and a worse metabolic profile.
In addition, individuals who consumed large quantities of meat cooked using unhealthy methods including, frying or grilling, had increased levels of high heterocyclic amines (HCAs) — pro-inflammatory compounds found in burned meat — and therefore developed insulin resistance.
People who are already diagnosed with NAFLD had similar consequences, along with an increased chance of cancer, Type 2 diabetes, and chronic heart diseases, researchers mentioned in the study, published in the Journal of Hepatology.
“Unhealthy Western lifestyle plays a major role in the development and progression of NAFLD, namely, lack of physical activity and high consumption of fructose and saturated fat,” Zelber-Sagi said.
“Our study looked at other common foods in the Western diet, namely red and processed meats, to determine whether they increase the risk for NAFLD,” she added.
In order to test the association of type of meat and cooking method with NAFLD and insulin resistance, the team included 357 participants, between 40 and 70 years of age.
NAFLD and insulin resistance were evaluated by ultrasonography and homeostasis model assessment (HOMA). Meat-type and cooking method were measured by food frequency and detailed meat consumption questionnaires.
Results showed that NAFLD was diagnosed in 38.7 per cent of participants and insulin resistance in 30.5 per cent.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
