Salty foods put children at risk of hypertension — Experts

Health experts are raising alarms about the regular consumption of salty foods, warning that it significantly increases the risk of hypertension in children. They urge parents to look beyond the salt shaker and pay closer attention to the hidden sodium in processed foods and seasonings.

Excessive sodium intake prompts the body to retain fluid, which in turn increases the volume of blood circulating through the vessels. This heightened volume places additional pressure on the blood vessel walls, a primary mechanism leading to high blood pressure. Children often consume sodium from everyday items like seasoning cubes, instant noodles, processed meats, crisps, and packaged snacks, making it easy for parents to underestimate their total intake.

It’s not just a one-off thing. There’s a risk of developing high blood pressure.

Dr. Abdurrazzaq Alege, Head of Paediatrics at the Federal Teaching Hospital, Katsina, explained that while the body has mechanisms to regulate excess sodium, a consistent habit of high salt consumption poses a serious risk. The kidneys work to remove excess sodium, but prolonged overconsumption can overwhelm these regulatory processes.

"It’s not just a one-off thing. There’s a risk of developing high blood pressure," Dr. Alege warned. He noted that hypertension beginning in childhood often persists into adulthood, significantly increasing the long-term risk of cardiovascular complications such as heart disease and atherosclerosis. Children with existing hypertension, kidney problems, or certain congenital conditions require particular attention to their sodium intake.

If the high blood pressure begins in childhood, there is a great chance that the child will continue to have hypertension even later in adulthood.
