High consumption of red and processed meat has been linked to non-alcoholic liposuction and insulin resistance, a new research has claimed.
According to Elsevier, non-alcoholic liposuction disease (NAFLD) has been added to the list of diseases associated with a Western diet containing relatively high consumption of red and processed meat.
World average meat consumption has increased in recent decades, and there is evidence that high consumption of red meat mainly is unhealthy to humans and is related to chronic diseases such as cancer, type II diabetes and cardiovascular disease.  "NAFLD is considered to be the hepatic component of the metabolic syndrome, with insulin resistance and inflammation as important factors in its pathophysiology," explained principal investigator Shira Zelber-Sagi.
"Unhealthy Western lifestyle plays an important role in NAFD's development and development, namely lack of physical activity and high consumption of fructose and saturated fat. Our study studied other common foods in Western food, namely red and processed meat, for to determine whether they increase the risk of NAFD. "
In order to test the association of type of meat and cooking method with NAFLD and insulin resistance, investigators conducted a cross-sectional study among individuals 40-70 years old who underwent screening colonoscopy and agreed to participate in a metabolic and hepatic screening study between 201
NAFLD and insulin resistance were evaluated by ultrasound and hemostasis model assessment (HOMA). Meat type and cooking method were measured with food frequency and detailed meat consumption form.
Unhealthy cooking methods were characterized as frying or grilling to a level of well done or very well done. These methods produce heterocyclic amines (HCA) which are proinflammatory compounds, and their intake was also calculated.
After exclusion of some participants due to factors such as viral liver disease and alcohol abuse, nearly 800 subjects were included in the main analysis, of which a subset of 357 subjects completed the gender form.
NAFLD was diagnosed in 38.7 percent of subjects and insulin resistance in 30.5 percent. The proportion of red and white meat intake was approximately one third and two thirds, similar to the typical diet of the Israeli population. High carnivores were a bit younger, mostly male, had a higher body mass index (BMI), calorie intake and a poorer metabolic profile.
The results showed that high consumption of red and processed meat is independently associated with NAFLD and insulin resistance independent of saturated fat and cholesterol intake and other risk factors such as BMI.
In addition, people who consumed large amounts of meat cooked with unhealthy methods and those already diagnosed with NAFLDs who consumed high HCA had a higher chance of having [insulin] resistance.
Low carb diets are often recommended to prevent metabolic diseases. These low carb diets can be very rich in animal protein, especially meat.
While meat contributes to valuable nutrients that are health promotion, including protein, iron, zinc and vitamin B12, the current survey shows that meat should be eaten in moderation and type of meat and its method of preparation should be chosen wisely.
Although the link between high red and processed meat consumption and NAFLD remains to be confirmed by future studies, Zelber-Sagi recommended to restrict red and processed meat consumption in preference to healthier "white meat" such as chicken or turkey, including fish in the diet and steam cooking or boiling food instead of grilling or cooking meat at high temperature until it is very well done.
"NAFLD is primarily a food-based disease. With healthy medical and nutritional orientation from its clinics, patients are better informed and equipped to implement the lifestyle changes needed to help reverse this sick ase," noted Zelber-Sagi.
The study is displayed in the Journal of Hepatology.
