Drinking three cups of coffee a day could halve the risk of liver cancer

Some proper reservations about the direction of causation expressed below

Three cups of coffee a day could reduce the risk of liver cancer by up to 50 per cent, latest research has shown.

One study found the drink reduces the risk of the most common type of liver cancer, hepatocellular carcinoma (HCC), by 40 per cent but separate research indicated that risk could be reduced by half.

Study author Dr Carlo La Vecchia, said 'Our research confirms past claims that coffee is good for your health, and particularly the liver.'

Dr Vecchia, of the department of epidemiology, Istituto di Ricerche Farmacologiche 'Mario Negri' and the department of clinical sciences and community health, Universit` degli Studi di Milan, Italy, added: 'The favorable effect of coffee on liver cancer might be mediated by coffee's proven prevention of diabetes, a known risk factor for the disease, or for its beneficial effects on cirrhosis and liver enzymes.'

The researchers conducted a meta-analysis of articles published between 1996 and September 2012, involving 16 high-quality studies and a total of 3,153 cases.

It also included data on 900 more recent cases of HCC published since the last detailed research in 2007.

Despite the consistency of results across studies, time periods and populations, it is difficult to establish whether the association between coffee drinking and HCC is causal, or if this relationship may be partially attributable to the fact that patients with liver and digestive diseases often voluntarily reduce their coffee intake.

Dr La Vecchia, whose research was published in the journal Clinical Gastroenterology and Hepatology, added: 'It remains unclear whether coffee drinking has an additional role in liver cancer prevention.

'But, in any case, such a role would be limited as compared to what is achievable through the current measures.'

Primary liver cancers are largely avoidable through hepatitis B virus vaccination, control of hepatitis C virus transmission and reduction of alcohol drinking.

These three measures can, in principle, avoid more than 90 percent of primary liver cancer worldwide.

Liver cancer is the sixth most common cancer in the world, and the third most common cause of cancer death.

HCC is the main type of liver cancer, accounting for more than 90 percent of cases worldwide.

Chronic infections with hepatitis B and C viruses are the main causes of liver cancer; other relevant risk factors include alcohol, tobacco, obesity and diabetes.


Eat chocolate to banish greys: How to munch your way to younger hair

This seems to be just opinion

You can spend hundreds on conditioners and treatments — but healthy, beautiful hair is more about what you put into your body than what you slather on your head.

Ricardo Vila Nova, resident trichologist at Urban Retreat in Harrods says: ‘Poor diet can cause hair thinning and hair loss as well as lacklustre hair, dryness and excess sebum.

A high-stress lifestyle and bad nutrition can be catalysts for damage which may need four years to recover.’

If your hair keeps breaking, eat red meat: ‘Iron is a top strength booster,’ says Vila Nova. It carries the blood’s supply of oxygen around the body keeping hair strong and nourished.

Thin and limp hair is the first sign that you aren’t getting enough iron.  As red meat is a great source of iron, eat a portion of beef or lamb at least twice a week.  Vegetarian? Lentils and tofu are also good  sources of iron.

Going grey? Try chocolate.

Melanin, the pigment that forms the colour in your hair and skin, is responsible for keeping your tresses vibrant.

Foods that boost the presence of melanin in your body include chocolate (especially the dark variety).

If you want softer hair, eating salmon might help as the Omega-3 and 6 it contains boost scalp health.

Essential fatty acids keep the scalp moisturised, help hair maintain hydration and elasticity.

Oily fish such as tuna, salmon and mackerel are excellent sources of fatty acids: eat them once or twice a week.

Finally, avocados and walnuts could boost hair shine.

The better lubricated the cuticle layer on your hair, the smoother the surface of the hair and the shinier it looks. Bon appetit!
