5 superfoods that aren't super
"Superfoods" are everywhere: smoothies, groceries, health blogs. Blueberries, kale, & chia seeds supposedly fight cancer, help you lose weight, & boost your mood.
These foods may seem like diet miracles. Deeper analysis of popular superfoods shows that the "super" label may be more marketing than science.
Kale
This leafy green is everywhere now, & for good reason. Kale is antioxidant-rich & high in iron & vitamin A. A deeper analysis of these numbers reveals a different picture.
You've probably seen chia-seed-containing energy bars, drinks, baked goods, & yoghurt cups. Global chia seed sales are expected to reach $1.5 billion by 2021.
Chia Seeds
This ancient South American grain gained popularity in the last five years for its high fibre, protein, & amino acid content.
Quinoa
After a 1996 Tufts University study found that darker fruits have high levels of antioxidants, blueberries gained superfood status.
Blueberries
Many of this berry's purported benefits are unproven, despite its high antioxidant & vitamin levels. According to the NHS, there's little evidence that goji berries can fight cardiovascular disease, cancer, or boost immune function.
