Goat milk prevents iron deficiency - study

A study of the nutritional benefits of goat milk, compared to cow milk, at preventing iron deficiency could prove to be a huge benefit to human health.

Research carried out at the Department of Physiology of the University of Granada (UGR) has found goat's milk not only helps prevent against ferropenic anaemia (iron deficiency) but also combats bone demineralisation (softening of the bones).

In the UK, cow milk dominates the market, which was estimated to be worth some £2.6bn in 2005. According to market analysts Mintel, goat milk makes up only a tiny percentage of milk volume sold - less than 100 million litres in 2005 of the total 4.8bn litres.

The study, conducted by Doctor Javier Castro and directed by professors Margarita Campos, Inmaculada Aliaga and José Alférez, focused on the comparison between the nutritional properties of goat milk and cow milk

Both types of milk had the normal calcium content and were calcium enriched, and were tested against the bioavailability of iron, calcium, phosphorus and magnesium in rats.

The rodents consuming the goat milk were found to have better levels of parathyroid hormone (PTH), a hormone that regulates calcium balance. This the group said, was because of goat's milk higher bioavailability of iron, calcium, phosphorus and magnesium.
