Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
Lipids: Dietary Sources and Requirements01:18

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...
Liver Physiology01:30

Liver Physiology

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can also...
Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Summary

New dietary guidelines impact liver health. Specific foods like fruits and vegetables protect against liver disease, while red meat and high protein intake may increase risk. Alcohol remains protective.

Area of Science:

  • Nutrition Science
  • Hepatology
  • Public Health

Background:

  • The 2025-2030 Dietary Guidelines for Americans (DGA-2025) updated nutrition recommendations, emphasizing total protein and removing alcohol guidance.
  • Steatotic liver disease (SLD), fibrosis, and cirrhosis are significant public health concerns in U.S. adults.

Purpose of the Study:

  • To evaluate the association between individual dietary components and liver outcomes (SLD, fibrosis, cirrhosis) in U.S. adults.
  • To assess the impact of updated dietary guidelines on liver health markers.

Main Methods:

  • Analysis of 10,944 U.S. adults from NHANES 2017-2023 with dietary recall and vibration-controlled transient elastography (VCTE).
  • Dietary exposures assessed using Healthy Eating Index-2020 (HEI-2020) components and z-scores for DGA-2025 food groups.
  • Logistic regression and stepwise models adjusted for confounders; alcohol adherence score derived from DGA-2020 thresholds.

Main Results:

  • High intake of fruits, vegetables, whole grains, and seafood/plant protein associated with lower odds of SLD and fibrosis.
  • Increased intake of red/processed meats, sodium, total protein, saturated fat, and added sugars linked to higher prevalence.
  • Alcohol adherence was strongly protective; greens/beans, seafood/plant protein, saturated fat, and alcohol use were independent predictors in stepwise models.
  • DGA-2025-emphasized components like total protein and red meat linked to fibrosis risk.

Conclusions:

  • Dietary patterns assessed by HEI-2020 and z-score models reveal specific components influencing liver health.
  • Nuance in dietary guidance is crucial, particularly concerning protein sources and alcohol consumption for liver disease prevention.
