High Blood Pressure: The Link to Salt
Salt has a sneaky way of raising blood pressure, a major risk factor for heart disease and stroke. By reducing sodium, you can lower your risk of developing these conditions. The effect of sodium on blood pressure is well-documented and presents a clear link to health risks.
Beyond Blood Pressure: Other Health Risks
Excess sodium is also linked to other health issues like kidney stones and osteoporosis. High sodium intake increases urinary calcium excretion, which can lead to these conditions. Reducing sodium can therefore have benefits beyond just managing blood pressure.
Understanding Sodium Sensitivity
Not everyone reacts the same way to salt; some people are more 'salt-sensitive,' meaning they experience a greater increase in blood pressure with high sodium intake. This sensitivity can be influenced by factors like age, race, and existing health conditions. Identifying salt sensitivity can help in personalizing dietary recommendations.
