Does regular consumption of meat affect your health?
Do you like eating red meat and is meat a normal part of your daily diet? Then maybe you should rethink your eating habits. According to a recent study, regular consumption of red and processed meat leads to an increased risk for the development of non-alcoholic fatty liver and the development of isulin resistance.
Researchers at the University of Haifa have found in their current research that regular red or processed meat-consuming people are at an increased risk of developing nonalcoholic fatty liver in their lives. The physicians published the results of their study in the English-language journal ” Journal of Hepatology “.

Western diet unhealthy?
The so-called Western diet has been repeatedly said in recent years that it is not particularly good for the health and can lead to various diseases. Such a diet involves a relatively high consumption of red and processed meat, explain the experts. Earlier studies had already revealed that red and mainly processed meat is at increased risk for cancer , Type-2 diabetes and cardiovascular diseases. According to the results of the latest investigation, such nutrition in addition also strongly the liver strain.
Western lifestyle involves too little exercise
According to the researchers, an unhealthy Western lifestyle plays an important role in the genesis and progression of non-alcoholics fatty liver , Such a lifestyle includes, for example, lack of physical activity and high consumption of fructose and saturated fats.
Subjects underwent a screening colonoscopy
To test the association of meats and cooking methods used with nonalcoholic fatty liver disease and insulin resistance, researchers conducted a cross-sectional study in individuals aged 40 to 70 years. Participants underwent a screening colonoscopy and agreed to participate in a metabolic and hepatic screening study between 2013 and 2015.
Roast and grilling unhealthy?
The risk of non-alcoholic fatty liver and insulin resistance was closely examined in the study. In addition, the meat type and cooking method as well as the frequency of consumption and detailed additional points were recorded using questionnaires. The cooking methods were taken into account in the study, as, for example, roast and barbecue are considered to be particularly unhealthy preparation methods. These processes produce so-called heterocyclic amines (HCAs) – inflammation-promoting compounds that promote the development of inflammation, explain the experts.
Main analysis included nearly 800 participants
Excluding the results of participants with factors such as viral liver disease and alcohol abuse, nearly 800 subjects were included in the main analysis. In another sample, another 357 people completed a questionnaire.
What did the investigation reveal?
The results showed that 38.7 percent of participants were diagnosed with nonalcoholic fatty liver. In addition, 30.5 percent suffered from insulin resistance. For the affected people, the proportion of consumed red meat was about one third, while the proportion of white meat was two thirds. This corresponded to the typical diet of the Israeli population, say the scientists. Among those with a high consumption of meat, there were a particularly large number of young men. These also had a higher body mass index (BMI), an increased calorie intake and a poorer metabolic profile, add the physicians.
Effects of consuming red meat
It has also been found that high consumption of red and processed meat leads to non-alcoholic fatty liver and insulin resistance, regardless of the intake of saturated fat and cholesterol and other risk factors, such as BMI. When people ingest large amounts of meat which has been prepared unhealthily and when people with previously diagnosed non-alcoholic fatty liver have consumed many heterocyclic amines, this increases the likelihood of developing insulin resistance.
Further research is needed
One of the limitations of the study was that it was based mainly on questionnaires. Direct links between consumption of red and processed meat and nonalcoholic fatty liver need to be further confirmed by prospective studies, say the authors. However, small improvements in nutrition could protect those affected. People should eat more healthier white meat, consume more fish, and make their food healthier, the doctors advise. (As)
