Salty foods put children at risk of hypertension — Experts
Health experts warn that regular consumption of salty foods, particularly processed items and seasonings, significantly increases children's risk of hypertension, potentially leading to long-term cardiovascular complications.

Experts highlight that excessive sodium intake causes fluid retention, increasing blood volume and pressure on blood vessel walls. While the body initially regulates this, prolonged high intake can overwhelm these mechanisms, leading to childhood hypertension that often persists into adulthood and raises the risk of heart disease.
Imagine your body is like a water balloon, and salt makes it hold onto too much water. When you eat lots of salty snacks, your body keeps extra water, making the balloon (your blood vessels) too full and tight. This extra pressure is called high blood pressure, and it can make your heart work too hard, which isn't good for you, especially when you're growing up.
Analysis
Dr Abdurrazzaq Alege
Dr. Abdurrazzaq Alege, Head of Paediatrics at the Federal Teaching Hospital, Katsina, and a Consultant Paediatrician, provided critical insights into the physiological impact of excessive sodium on children. He explained that the kidneys play a vital role in regulating sodium balance and fluid levels in the body, initially attempting to remove excess sodium after consumption.
However, Dr. Alege emphasized that when high salt intake becomes a regular habit, these natural regulatory mechanisms can become less effective. This sustained imbalance increases the risk of developing high blood pressure, which, if it begins in childhood, has a significant chance of continuing into adulthood. He explicitly linked prolonged hypertension to severe cardiovascular complications, including heart disease and atherosclerosis.
Olusola Malomo
Olusola Malomo, Assistant Director of Dietetics at the Lagos State Health Service Commission, General Hospital, Badagry, reinforced the need for parents to broaden their focus beyond just the salt added during cooking. Malomo stressed that many processed foods, such as seasoning cubes, instant noodles, processed meats, crisps, and packaged snacks, are significant hidden sources of sodium in children's diets.
He highlighted that children's sodium requirements vary by age and should not simply mirror adult dietary habits. Malomo advised parents to actively reduce the amount of heavily salted and highly processed foods given to children, advocating for the use of natural ingredients to enhance meal flavors instead. This approach aims to shape children's taste preferences towards less salty options from an early age.
2017 Systematic Review
The concerns raised by health experts are substantiated by local research, specifically a 2017 systematic review conducted by Nigerian researcher Chukwunonso E.C.C. Ejike. Published in the Journal of Tropical Pediatrics, this comprehensive review analyzed 30 different studies focusing on the prevalence of hypertension among Nigerian children and adolescents.
The findings of the review were particularly alarming, revealing that 5.1 percent of Nigerian children and adolescents were diagnosed with hypertension. Furthermore, an additional 8.2 percent were found to have prehypertension, indicating a substantial portion of the young population is already at risk. This data underscores the urgency of addressing dietary sodium intake to mitigate a growing public health crisis in the region.
Key points
- Regular consumption of salty and processed foods increases children's risk of hypertension.
- Excess sodium causes fluid retention, increasing blood volume and pressure on blood vessels.
- Childhood hypertension often persists into adulthood, leading to long-term cardiovascular complications like heart disease.
- Parents should monitor hidden sodium in seasoning cubes, instant noodles, processed meats, and snacks, not just added salt.
- A 2017 Nigerian review found 5.1% of children and adolescents had hypertension, with 8.2% having prehypertension.
Increased parental awareness of hidden sodium in processed foods could lead to healthier dietary choices for children, potentially reducing the prevalence of childhood hypertension. Early intervention and education can foster better eating habits, safeguarding children's cardiovascular health into adulthood.
Without significant changes in dietary habits and increased awareness, the rates of childhood hypertension and associated cardiovascular diseases are likely to continue rising. This could place a greater burden on public health systems and lead to a generation facing chronic health issues earlier in life.
