Soya: the health protector - The health effects of SoyaBlood Pressure
High blood pressure (hypertension) also increases the risk of heart attack and stroke. This condition affects 40 per cent of adults in England (NHS Choices, 2008). People with hypertension are often prescribed drugs to lower their blood pressure.
However, the diet can also affect it. For example, limiting salt intake can lower blood pressure. Some studies suggest that soya protein could lower blood pressure. A study looking at the effects of soya protein and isoflavones on cholesterol and blood pressure among 61 high risk middle-aged Scottish men found that diets containing at least 20g of soya protein (80mg of isoflavones) for five weeks lowered both cholesterol and blood pressure (Sagara et al., 2004). A larger 12-week trial involving 300 people with high-normal or mildly elevated blood pressure found that 40g of soya protein per day significantly lowered blood pressure (He et al., 2005). These findings suggest soya protein can play an important role in preventing and treating hypertension. This is important as even small reductions in blood pressure can significantly lower the risk of heart disease and stroke. In summary, the effect of soya protein may allow some people to avoid the use of blood pressure-lowering and cholesterol-lowering medications.
