High-sodium foods can negatively impact health by elevating blood pressure and increasing the risk of cardiovascular diseases. Excessive salt intake can lead to water retention, burdening the heart and circulatory system. Over time, chronic high sodium consumption has been linked to conditions such as hypertension, heart disease, and stroke. It's essential to monitor sodium intake and opt for whole foods with lower salt levels, as maintaining a balanced sodium intake is vital for overall health and reducing the risk of these serious health complications.
