Milk protein lowers blood pressure

New Orleans: Milk contains a protein that can lower blood pressure significantly.

A trial of 140 patients carried out at Tulane University demonstrated a drop in blood pressure of between trhee and five percent.

The results from this study mean that protein supplements could be used in the prevention and treatment of high blood pressure in the general population.

Just how proteins from milk work is not clear, although it is known that other foods, such as salt, potassium and alcohol, can have an effect on blood pressure.

Now a bigger clinical trial has been launched to investigate the effects and to compare it to proteins found in soy, which researchers believe may have a similar effect.

Those taking part will get 40g of milk or soy protein supplements, or a placebo, for eight weeks.
