Paper abstract

This randomized clinical study evaluated the effects of using dried powdered perennial Salicornia (Sarcocornia perennis) as a substitute for common salt for 30 days in healthy young adults. Biochemical parameters (cholesterol, triglycerides, creatinine, glucose) and the activity of matrix metalloproteinases MMP-2 and MMP-9, which are related to inflammatory processes, were analyzed.

The intervention group showed a statistically significant reduction in total cholesterol, HDL cholesterol, and creatinine levels, as well as a non-significant trend toward decreased triglycerides and MMP-9 activity. No significant differences were observed in MMP-2 levels. The powder composition showed a nutritional profile rich in minerals, phenolic compounds, and antioxidant activity.

Key points

  • Randomized clinical trial with 30 healthy young adults.
  • Replacement of table salt with Salicornia for 30 days.
  • Significant reduction in total cholesterol, HDL-C, and creatinine in the intervention group.
  • Trend toward decreased triglycerides and MMP-9 activity (an enzyme associated with inflammation).
  • Salicornia powder with high content of:
    • Sodium, potassium, magnesium, and calcium.
    • Phenolic compounds (15.79 mg GAE/g) and high antioxidant capacity (58.49 mg Trolox/g).
  • Presence of flavonoids, carotenoids, saponins, tannins, and other bioactive ingredients with antioxidant, anti-inflammatory, and cardioprotective properties.
  • Potential as a functional ingredient in low-sodium products.
  • Applicability in the prevention of cardiovascular and metabolic diseases.
