Junk Food May Put Your Kids at Fatty Liver Disease Risk
Every chemical that makes it into your bloodstream – be it through your lungs, stomach, or skin – meets up with your liver at some point. Since your liver is your body’s best defense when it comes to filtering out all those toxins, you need to treat it well – Suzanne Somers

The human body’s largest internal organ, the liver, resembles an irregularly shaped, dome-like structure. It normally weighs 1.44 to 1.66 kilos. We take a look at different aspects of this important organ and focus on the rise in non-alcoholic fatty liver disease in children caused by junk foods.


The liver produces bile, a substance that helps digest fats and aids digestion. The salt secreted by the bile is responsible for breaking up fat into small pieces so that is easily absorbed in the small intestine. It is important to remember that everything that you eat or drink, including medicines, must pass through the liver first. Therefore, without a healthy and functioning liver, a person cannot survive.

Functions of liver:

The liver performs many essential functions. It - 

• Fights infection and illness

• Regulates and stores glucose

• Stores vitamins and iron

• Removes toxic substances from the body

• Controls cholesterol levels

• Helps in the clotting (thickening) of blood

• Converts ammonia to urea, which is vital for metabolism

• Destroys old red blood cells

Liver disease:

The signs and symptoms of liver disease vary from person to person. Some common symptoms include loss of appetite, rapid weight loss, bleeding, fatigue and jaundice. The advanced stage of liver disease includes hepatitis infection (Hepatitis A, B, and C), fatty liver disease and liver cirrhosis.

Caring for the liver:

The first step in caring for the liver is to maintain a healthy lifestyle. Some ways to care for your liver include:

  • Eat healthy; eat foods from all food groups and foods that have a lot of fibre in them. Follow a diet rich in protein, dairy products, fruits, vegetables, fats, whole grain breads, rice and cereals.
  • Consult the doctor before taking any medication. When medicines are taken incorrectly or in the wrong combination, it leads to liver damage.
  • Maintain proper weight. Obesity, especially in children, can lead to non-alcoholic fatty liver disease.
  • Avoid alcohol, smoking, and drugs.
  • Be wary of toxic chemicals in cleaning products and insecticides that harm the liver.
  • When in doubt, get yourself examined and undergo the liver function test.
  • Get your hepatitis vaccination shots.
  • Follow a healthy lifestyle: get adequate sleep, exercise regularly and avoid stress.

Natural ingredients that benefit the liver:

Keep your liver healthy with these natural ingredients that are inexpensive and easy to find.

• Grapefruit, garlic, carrot, apple, walnuts, and leafy green vegetables

• Olive oil

• Lemon, lime juice and green tea

• Millet, quinoa, and buckwheat

• Turmeric, beetroot and avocado

Fatty liver disease in kids: Could junk food be the culprit?

A startling fact that has emerged in recent times is the direct connection of consumption of obesity-causing junk food to a liver condition in children called Fatty Liver Disease. With children forgoing healthy, home-cooked food in favour of fast food, obesity and cases of fatty liver disease, have shot up significantly.

What is fatty liver disease?

Fatty liver disease is characterised by an increase in the accumulation of fat in the liver cells. This can be attributed to the consumption of excess calories in the diet. Children who consume junk food are at risk of developing this disease because such food is high in calories. The liver is unable to metabolise this high-calorie food and it leads to fat accumulation in the liver.

What causes fatty liver disease?

There are two main types of fatty liver disease - Alcoholic Liver Disease (ALD) and Non-Alcoholic Fatty Liver Disease (NAFLD). While consumption of alcohol leads to acquiring the former, it is said that consumption of high-calorie foods leads to acquiring the latter. And, that is what concerns our children.


The diagnosis of fatty liver disease can be confirmed with the help of a liver biopsy. This procedure involves inserting a needle between two of the right lower ribs to remove a sample of liver tissue.


Although, there is currently no medicine effective enough, you can start by making changes to your lifestyle. Treatment of liver disease includes a balanced diet, lots of physical activity and weight loss so that the amount of fat in the liver can be reduced. However, weight loss must be a gradual process.

There are many factors that lead to obesity in children, junk food being the number one factor. If parents start following a healthier lifestyle at home, children will follow suit. Over time, this will influence children positively in the selection of foods leading to lower cases of obesity and liver disease in children.
