Superfoods - Hype or Health?

"Superfood" as a marketing term: All sources acknowledge that "superfood" is a marketing term with no official scientific definition. The EU even banned its use on labels without authorised health claims (source 1). Despite this, consumer interest and product sales using "super" labelling remain high (source 1 & 3).
Nutrient Density: While a balanced diet is paramount, certain foods stand out for their high concentration of beneficial nutrients. These include vitamins, minerals, antioxidants, fibre, and healthy fats (all sources).
Evidence-based benefits vs. hype: Sources emphasize differentiating between proven benefits and marketing hype. Some "superfoods" have robust research backing their health claims (salmon, green tea, turmeric), while others require further investigation (acai, chia seeds) (source 4).
Plant-based dominance: Notably, the top superfood lists in both the dietitian surveys (source 3 & 5) are entirely plant-based, reflecting a growing emphasis on plant-focused diets for health.
