High-sodium foods
High-sodium foods are considered unhealthy because they can contribute to high blood pressure, a leading risk factor for heart disease and stroke. Sodium is a mineral that is commonly added to processed and packaged foods, as well as many restaurant dishes, to enhance flavor and preserve shelf life. Consuming too much sodium can lead to water retention, which can raise blood pressure and put extra strain on the heart and blood vessels. High-sodium foods include cured meats, canned soups, processed snack foods, salted nuts, and many condiments. It is recommended to limit sodium intake to less than 2,300 milligrams per day, or 1,500 milligrams for those with high blood pressure or other risk factors. Choosing fresh, whole foods, and cooking at home can help to reduce sodium intake and improve overall health.
