Chronic choline deficiency in diets can lead to fatty liver, irrespective of the overall diet’s healthiness, although it’s not the sole factor responsible. Fatty liver affects at least 25-30% of the population, and this prevalence tends to increase significantly in later life stages, impacting even young individuals.
Commonly recognized factors that contribute to NAFLD include obesity, type II diabetes, dyslipidemia, and insulin resistance. It’s important to note that these conditions are often associated with a diet rich in processed foods, although not exclusively.
In a study conducted in 2021, it was discovered that 13.2% of individuals aged 12 to 17 have non-alcoholic fatty liver disease (NAFLD), while the prevalence increases to 18.7% among those aged 18-24, and a striking 24% among individuals aged 25-30.
This article investigates the prevalence trends of nonalcoholic fatty liver disease (NAFLD) among adolescents and young adults in the United States from 2007-2016. To perform the study, the authors used data from the National Health and Nutrition Examination Survey (NHANES), which is administered every two years and collects information on various health and lifestyle factors. Logistic regression models were used to analyze the data and determine trends in NAFLD prevalence over time, adjusted for demographic factors such as sex and race/ethnicity.
The study found that the overall prevalence of NAFLD among adolescents and young adults in the United States increased significantly from 9.9% in 2007-2008 to 15.8% in 2015-2016. Furthermore, males had a higher prevalence of NAFLD than females (19.1% versus 12.4%), and Hispanics had the highest prevalence of NAFLD among all racial/ethnic groups (19.1%). The prevalence of NAFLD also increased with age; the highest prevalence was seen among young adults aged 25-29, while the lowest prevalence was seen among early and middle adolescents aged 12-17.
In terms of risk factors, the study found that obesity was strongly associated with NAFLD prevalence. The prevalence of NAFLD among those with obesity was 36% compared to 8.2% among those without obesity. Additionally, the prevalence of NAFLD was significantly higher among those with type 2 diabetes compared to those without (34.6% versus 7.5%). Other demographic factors associated with higher NAFLD prevalence included being male, Hispanic, and of older age.
One interesting finding of the study was that the prevalence of NAFLD among early and middle adolescents (aged 12-17) and young adults (aged 25-29) remained stable over the course of the study period, while the prevalence among late adolescents aged 18-24 increased dramatically from 10.7% in 2007-2008 to 24.8% in 2015-2016, a significant increase of 132%. The authors suggest that this increase may be due in part to the higher rates of obesity and type 2 diabetes in this age group, particularly among White and Hispanic individuals.
The authors note that the increasing prevalence of NAFLD among adolescents and young adults is a cause for concern, as NAFLD can have serious health consequences and may lead to liver cirrhosis, liver cancer, and other diseases. They also suggest that the high rates of obesity and type 2 diabetes among these population groups are likely contributing to the increase in NAFLD prevalence and that efforts to prevent and treat NAFLD should focus on addressing these underlying health problems. The authors suggest that dietary interventions and physical activity programs may be effective in reducing NAFLD prevalence, and that further research is needed to identify effective prevention and treatment strategies for this condition
Choline is an essential nutrient that plays many important roles in the human body, including brain and liver function, cell membrane structure, and nerve signaling. Although the human body can produce some choline on its own, dietary sources are also necessary to meet daily needs. Good sources of choline include eggs, liver, certain meats, fish, and cruciferous vegetables like broccoli and Brussels sprouts.
The 2015-2020 Dietary Guidelines for Americans recommend that adults consume 550 mg of choline per day. Pregnant and lactating women have higher needs, with a recommended daily intake of 450 mg and 550 mg, respectively. However, national surveys indicate that many Americans do not meet these recommendations, with average daily intakes ranging from 250 to 402 mg depending on gender and age.
Research on the health effects of choline is ongoing, but studies have suggested that adequate intake may be important for preventing liver disease, cognitive decline, and birth defects. Some evidence also suggests that choline may play a role in reducing inflammation and improving metabolic health.
Choline requirements may vary depending on genetic factors, with some individuals requiring higher intakes due to genetic polymorphisms affecting choline metabolism. However, no widespread genetic testing for choline status currently exists, and more research is needed to better understand the relationship between genetics and choline requirements.
Here are my top 10 recommended choline-rich food sources:
1. Eggs, especially the yolk
2. Beef Liver
3. Chicken Liver
5. Wheat Germ
7. Chickpeas (Garbanzo Beans)
8. Split Peas
9. Navy Beans
Remember, it’s important to diversify your choline intake by incorporating various sources for a balanced diet.
In addition to dietary sources, choline is also available in supplement form. However, the safety and efficacy of choline supplements remain unclear, and more research is needed to determine optimal dosages and possible health risks associated with long-term supplementation.
Overall, while choline is an important nutrient with many potential health benefits, more research is needed to determine optimal intake levels and the long-term effects of choline supplementation. In the meantime, meeting daily needs through a balanced diet that includes choline-rich foods is likely the best strategy for maintaining good health.
