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.
Suicide can’t be predicted by asking about suicidal thoughts : Study
Most people who died of suicide deny they experience suicidal thoughts when asked by doctors in the weeks and months leading up to their death, a major Australian study has found.
The findings, co-authored by clinical psychiatrist and Professor Matthew Large from UNSW’s School of Psychiatry, Sydney that published in the journal BJPsych Open The meta-analysis challenge the widely-held assumption that psychiatrists can predict who will suicide by asking if they are preoccupied with thoughts of killing themselves.
The study showed that 80% of patients who were not undergoing psychiatric treatment and who died of suicide reported not to have suicidal thoughts when asked by their psychiatrist or GP.
“If you meet someone who has suicidal ideation there is a 98 per cent chance that they are not going to suicide,” said Professor Large, an international expert on suicide risk assessment who also works in the emergency department of a major Sydney hospital.
“But what we didn’t know was how frequently people who go on to suicide have denied having suicidal thoughts when asked directly,” he added.
“This study proves we can no longer ration psychiatric care based on the presence of suicidal thoughts alone. We need to provide high-quality, patient-centred care for everyone experiencing mental illness, whether or not they reveal they are experiencing suicidal thoughts,” Professor Large said.
About one in 10 people will have suicidal ideation in their lifetime. But the study showed suicidal ideation alone was not rational grounds for deciding who gets treatment and who does not, Professor Large said.
“We know that suicide feeling is pretty common and that suicide is actually a rare event, even among people with severe mental illness,” Professor Large added.
Suicidal ideation tells us an awful lot about how a person is feeling, their psychological distress, sometimes their diagnosis and their need for treatment but it’s not a meaningful test of future behaviour.
Suicidal feelings can fluctuate rapidly and people may suicide very impulsively after only a short period of suicidal thoughts.
But, people had good reasons not to disclose thoughts of suicide, fearing stigma, triggering over-reactions or upsetting family and friends, and being involuntarily admitted for psychiatric treatment, Professor Large said.
Professor Large emphasized that clinicians should not assume that patients experiencing mental distress without reporting suicidal ideas were not at elevated risk of suicide.
