Urban Detox™ is grounded in plant-based nutrition research for everyday metabolic wellness. Three studies on leafy greens and spirulina are summarised below.
1. Green Intelligence: Why Leafy Vegetables Are Nutrient-Dense
- Leafy vegetables provide substantial nutrition with relatively few calories.
- They supply vitamins C, E and K, folate, minerals, fibre, carotenoids, chlorophylls and polyphenols.
- Together, these components contribute antioxidant and anti-inflammatory activity and support normal cellular metabolism.
- Fibre supports bowel regularity, beneficial gut microorganisms and more gradual post-meal glucose responses.
- Carotenoids offer antioxidant protection, while natural nitrates in selected greens may support vascular function.
- Nutrient content varies by species, cultivation, maturity, storage and cooking, making dietary variety important.

2. Metabolic Greens: Multiple Nutrients, Complementary Pathways
- Metabolic syndrome combines abdominal obesity, elevated blood pressure, insulin resistance and abnormal blood lipids.
- Leafy greens provide fibre, magnesium, folate, polyphenols, antioxidants and natural nitrates.
- These components may support satiety, glycaemic control, endothelial function and healthy blood-pressure regulation.
- They may also influence oxidative stress, inflammatory signalling, lipid metabolism and gut-microbiota activity.
- Observational evidence links greater vegetable intake with better cardiometabolic outcomes but cannot prove causation.
- Benefits depend on the total dietary pattern, preparation method, physical activity and individual health status.

3. Blue-Green Potential: Spirulina and Cardiometabolic Markers
- Spirulina is a cyanobacterium containing protein, phycocyanin, carotenoids, polyunsaturated fatty acids, vitamins and minerals.
- Clinical studies suggest supplementation may modestly support weight, BMI, waist circumference, body fat and appetite.
- In one 12-week study, 2 g daily alongside calorie restriction produced greater anthropometric reductions than diet alone.
- Research also suggests possible reductions in triglycerides, total cholesterol and LDL cholesterol, with variable HDL effects.
- Proposed pathways include antioxidant and anti-inflammatory activity, insulin sensitivity and altered cholesterol absorption and excretion.
- Variation in populations, doses and study duration means spirulina should remain an adjunct to established lifestyle and medical care.
