All wrong, we're afraid. In fact, a superfood is simply "a food which is very good for your health", as defined by the English dictionary. So that can be anything from a stick of celery to a handful of sunflower seeds, or even a slice of wholegrain toast.
To understand this mystical league of foodstuffs a little better, we've done our research and answered the most common superfood questions for you...
1. A plain old apple is good for you. Does that mean it's a superfood?
Yes, indeed it does. An apple a day provides a quarter of your daily requirement of vitamin C, which keeps skin glowing and gums healthy.
2. Is there a superfood which isn't a fruit or vegetable?
Yes, although most do fall in the fruit & veg category. Examples include baked beans (jam-packed with iron and calcium), olive oil (rich in antioxidants) and salmon (omega 3 fats dramatically reduce the risk of having a heart attack, among other things).
3. Is it true that eating superfoods reduces the risk of getting cancer?
Hmmmm, tricky one. Some experiments have suggested so, but only for specific superfoods such as bananas, brazil nuts, blueberries and broccoli. The four B's!
4. What's the super-est superfood in the world?
Everybody has different opinions on that. But one that always seems to be up there is blueberries. They're choc-a-bloc with a specific type of antioxidant which has potential benefits for the nervous system, brain health, eyesight and even memory improvement...
4. What's with wheatgrass juice? Apparently one shot is equal to a kilo of vegetables.
Far too much hype around this. 30 ml of wheatgrass juice contains less folic acid and vitamin C than just two florets of broccoli.
5. So should I be gorging on superfoods?
No! You can overdose on superfoods. If we have an excess of nutrients and cannot store them, they will essentially go to waste. And if they can't be excreted, certain nutrients could even cause cellular damage.
