Got milk? Milk consumption associated with a higher rate of death. Does not lower risk of fracture.

milkA new study has demonstrated that high intake in women and men may have an adverse impact, linked to a higher risk of fractures and death. has been touted as a preventative mechanism to prevent bone fractures.

The adverse was attributed to high levels of lactose and galactose in which acts to increase oxidative stress and in animal studies.

The research participants consisted of two large groups of 61,433 women (aged 39-74 years in 1987-1990) and 45,339 men (aged 45-79 years in 1997) in Sweden who completed food frequency questionnaires for 96 including , yogurt and cheese.

The study tracked lifestyle information. National registers were used to track fracture and mortality rates.

The women were tracked for an average of 20 years, during which time 15,541 died and 17,252 had a fracture, of whom 4,259 had a hip fracture. In women, no reduction in fracture risk with higher consumption was observed. Furthermore, women who drank more than three glasses of a day (average 680 ml) had a higher risk of death than women who drank less than one glass of 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 consumption, although this was less pronounced than in women.

In direct contrast, a high intake of fermented products with a 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 in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death. They suggest that further analysis is needed.
