The term "superfood" isn’t a scientific classification — it’s a marketing label used to highlight nutrient-dense foods thought to offer exceptional health benefits. Think chia seeds, quinoa, goji berries, acai, and spirulina. While these foods often pack impressive amounts of vitamins, antioxidants, or healthy fats, the hype surrounding them can sometimes obscure their true environmental and social impact.
Superfoods often come from specific ecosystems and regions — many in the Global South — where rising demand from wealthier markets can put pressure on local communities, biodiversity, and food security. That’s why it’s important to evaluate not just the nutritional profile of a food, but also how it’s grown, harvested, and transported.
Let’s take a closer look at a few high-profile examples:
Quinoa: Once a staple food in the Andes, quinoa’s global popularity has led to increased prices, making it less accessible to local communities in Bolivia and Peru. Additionally, land previously used for rotational farming has been pushed into intensive monoculture, leading to soil degradation (FAO, 2013).
Avocados: Beloved for their healthy fats, avocados are notoriously water-intensive. In Mexico, the top exporter, rising global demand has been linked to deforestation, overuse of water resources, and in some areas, organized crime taking control of the trade (BBC, 2020).
Chia Seeds: Originally grown in Central and South America, chia farming has expanded to meet global demand. While chia requires less water than many other crops, the environmental footprint largely depends on how far it travels and whether it’s grown using sustainable practices.
Acai Berries: Harvested from the Amazon rainforest, acai can be grown in biodiverse environments that protect rather than replace the forest. However, unsustainable harvesting and mass commercialization can lead to the disruption of local ecosystems if not properly managed.
Almonds: While not technically a “superfood,” almonds are often grouped with them due to their high nutrient content. Most almonds are grown in drought-prone California and require approximately 1.1 gallons of water per almond (UC Davis, 2019), raising concerns about their long-term sustainability in water-scarce regions.
Often, local alternatives can offer similar nutritional benefits with a smaller environmental footprint. For example:
Eating a variety of regionally appropriate, seasonal foods not only reduces emissions from transport but also supports biodiversity and local food systems.
When selecting superfoods — or any food — consider the following:
Superfoods aren’t inherently bad — but they’re not automatically good, either. They exist in a global system that requires us to think about health, equity, and sustainability in tandem. By asking where our food comes from and how it’s produced, we can make choices that nourish both ourselves and the planet.
