Answers: Are superfoods actually healthy and sustainable?

• Quinoa cultivation in Bolivia
• Environmental impact of superfoods
• Avocado water consumption
• Superfood marketing and nutrition
• Pesticide residue in superfoods

What it concludes

• Quinoa has comparable protein to millet and more fiber, but millet contains more than twice as much iron.
• Mass cultivation of quinoa in Bolivia has led to 150,000 to 200,000 hectares of llama grazing land being plowed up, clearing protective vegetation and causing soil erosion.
• Avocado production has grown massively worldwide, requiring 1,500 liters of water per kilogram, far more than local vegetables like lettuce and tomatoes.
• Many processed superfood products in supermarkets contain high amounts of sugar and fats, making them unhealthy despite their marketing.
• Chia seeds do not provide significant omega-3 fatty acids compared to a generous portion of walnuts.
• Goji berries have seven times more calories than black currants and less vitamin C, while often containing higher pesticide residues due to less strict farming regulations abroad.
