High milk intake tied to increased mortality risk

Drinking more than 700 ml of milk a day could increase the risk of early death, a new study has warned.

Researchers led by Professor Karl Michaelsson of Uppsala University in Sweden have found that high levels of lactose and galactose sugar in milk could have a negative effect. The study, which surveyed 61,000 women and 45,000 men for more than 20 years, found that those who drank one and a half pints, or over 700 ml of milk a day were twice as likely to die early than those who drank less.

In the study 61,433 women, aged 39 to 74, and 45,339 men, aged 45 to 79, in Sweden completed food frequency questionnaires for 96 common foods including milk, yoghurt and cheese.

The scientists set out to examine whether high milk intake may increase oxidative stress, which in turn affects the risk of mortality and bone fracture, according to media reports.

In women, no reduction in fracture risk with higher milk consumption was observed. Women who drank more than three glasses of milk a day (average 680 ml) had a higher risk of death than women who drank less than one glass of milk a day (average 60 ml).

Men were tracked for an average of 11 years, during which time 10,112 died and 5,066 had a fracture, with 1,166 hip fracture cases. Men also had a higher risk of death with higher milk consumption, although this was less pronounced than in women.

Further analysis showed a positive association between milk intake and biomarkers of oxidative stress and inflammation.

In contrast, a high intake of fermented milk products with low lactose content - including yoghurt and cheese - was associated with reduced rates of mortality and fracture, particularly in women.

The researchers concluded that a higher consumption of milk in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death.  source-hindu
