1. Watch your alcohol intake
Your liver performs 500 vital functions. Every time it filters alcohol, it has to work a little harder and some of its cells die.
Drinking large amounts, even just for a few days, may cause a build-up of fats known as alcoholic fatty liver disease, which can potentially lead to a life-threatening illness. So give yourself a break. Drink no more than 14 units of alcohol, and have at least two or three booze-free days, each week.
Need inspiration? In a study at London's Royal Free Hospital, regular drinkers who cut out alcohol for a month saw an average 15 per cent reduction in liver fat and significant improvements in their cholesterol and blood sugar levels.

2. Reduce your portion sizes
Alcohol isn't the only major culprit when it comes to liver health.
Around a third of the UK population suffers from non-alcoholic fatty liver disease (NAFLD) – a build-up of liver fat that's normally associated with being overweight or obese.
In fact, some experts believe overeating will soon overtake alcohol as the main cause of liver disease. One way to trick yourself into downsizing your portions is to use smaller plates and cutlery, according to a study at the University of Cambridge.
Eliminating larger-sized portions from the diet completely could reduce calorie intake by up 16 per cent, and so hold the key to weight loss, say the researchers.

3. Cut down on fizzy drinks
Just one sugar-sweetened soft drink each day is associated with an increased risk of NAFLD, according to research from Tufts University in the US. So switch to diet versions – or better still, drink water instead. Talking of which...

4. Drink plenty of water
Water plays a crucial role in helping the liver flush toxins out of your system. Not drinking enough will cause the blood to thicken, making it more difficult to filter.
Everyone's fluid needs vary – but as a rough guide, you should aim to drink around 1.2 litres water daily.

5. Have a (decaff) coffee break
There's evidence to suggest that coffee may be good for the liver, too. Researchers at the National Cancer Institute in the US found that people who drink at least three cups of decaffeinated coffee each day had lower levels of abnormal liver enzymes, suggesting that chemical compounds other than caffeine in coffee may protect the liver.

6. Stop smoking
Yes, it's that point in the feature when we remind you just how deadly cigarettes are. Smoking is a risk factor for liver disease and can exacerbate the symptoms.
Nicotine raises the levels of fat in the blood, while the liver has to work hard to filter all those smoking-related toxins. Need help quitting? Go to www.nhs.uk/smokefree.

7. Get moving
Regular exercise will boost your overall health, which in turn has a positive effect on liver function.
Remember, every little helps: any exercise, regardless of frequency or intensity, can be of benefit to people with NAFLD, according to research published in the Journal of Hepatology.
And prolonged periods of sitting appear to increase risk of the condition, say scientists in South Korea.
So start by trying to build more 'incidental' exercise into your day: stand up and walk around when you're on the telephone, for example.

8. Eat more nuts
Upping your intake of vitamin E can help reduce symptoms of liver disease by preventing cell damage, according to researchers at Case Western Reserve University School of Medicine in the US. Good sources include nuts, seeds, wheatgerm, leafy greens and vegetable oils.

9. Cut down on carbs
A low-carbohydrate diet could improve the liver function of people with NAFLD, according to research published in the journal Diabesity in Practise. Dr David Unwin, the study's author, believes sugar and starchy foods, such as bread and potatoes, pose a particular threat. This is because they are rapidly turned into glucose, which is initially stored in the liver while any excess is stored as body fat. But do speak to your GP before embarking on any kind of low-carb diet.
