a study of KK Medicine de la USC published in Clinical Gastroenterology and Hepatology Gives people extra motivation to reduce consumption fast food,
The study found that hamburgers, hot dogs, pizza or… Nugget is attached to nonalcoholic fatty liver diseaseA life-threatening condition in which fat accumulates in the liver.
Researchers found that people with obesity or diabetes who ate 20 percent or more of their daily calories from fast food had significantly higher levels of liver fat than those who ate little or no fast food. And when a fifth or more of their diet is fast food, there is a moderate increase in liver fat in the general population.
“Healthy livers contain a small amount of fat, usually less than 5 percent, and even a slight increase in fat can lead to nonalcoholic fatty liver disease,” he said. Annie Kardashian, MD, Keck Medicine hepatologist and lead author of the study. “The severe increase in liver fat in people with obesity or diabetes is particularly striking, and is probably due to the fact that these conditions lead to an increased susceptibility to fat accumulation in the liver.”
While previous research has shown a link between fast food and obesity and diabetes, this is one of the first studies to show the negative effects of fast food on liver health, according to Kardashian.
If that food equals one-fifth of your daily calories, you’re putting your liver at risk.
The findings also suggest that relatively small amounts of fast food, high in carbohydrates and fat, can damage the liver. “If people eat one meal a day at a fast food restaurant, they may think they’re not causing any harm,” Kardashian said. “However, if that food equals at least a fifth of their daily calories, they are putting their livers at risk.”
Nonalcoholic fatty liver disease, also known as hepatic steatosis, can lead to cirrhosis, or scarring of the liver, which can lead to cancer or liver failure. Hepatic steatosis affects over 30% of the US population.
Kardashian and colleagues analyzed the most recent data from the 2017-2018 National Health and Nutrition Examination Survey, the nation’s largest annual nutrition survey, to determine the effect of fast food consumption on fatty liver disease.
The study characterized fast food as meals, including pizza, from self-service restaurants with or without waiters. Researchers evaluated fatty liver measurements of nearly 4,000 adults whose fatty liver measurements were included in the survey and compared these measurements to fast food consumption.
52% of those surveyed consumed some fast food. Of these, 29% consumed a fifth or more of their daily calories from fast food. Only 29% of those surveyed experienced increased levels of fat in the liver.
Even after the data were adjusted for many other factors including age, gender, race, ethnicity, alcohol use, the association between fatty liver and a 20% fast food diet remained stable for both the general population and those with obesity or diabetes. physical activity.
“Our findings are especially alarming because fast food consumption has increased over the past 50 years regardless of socioeconomic status,” Kardashian said. “We have also observed a substantial increase in fast food meals during the COVID-19 pandemic, which is likely related to declines in full-service restaurant dining and increased rates of food insecurity. We are concerned that the number of people with fatty liver has increased further since the time of the survey.”
