What is a superfood?

There is no strict definition for the term “superfood” - the label is splashed over everything from smoothies to cereal bars, fruit juices to teas. While opinions on the matter vary, the general consensus is they must be natural foods high in nutrition. Some products claim to have remarkable powers from boosting your immune system to upping your mood. However, following new EU legislation, terms such as “superfood” will have to be supported by evidence showing why the food is healthy.

What exactly are the health benefits?

Most foods given the “superfood” tag have a high density of phytochemicals - antioxidants which combat damaging free-radicals in the body that can cause problems from premature aging to cancer. Scientists believe that phytochemicals could also act in other ways to prevent disease.

Are there any risks?

As all superfoods are natural and wholesome, it is generally acknowledged they contribute to a healthy diet. However, there are sceptics about some of the ambitious claims. A few berries alone won’t keep you healthy - what is most important is a balanced diet. Nutrients from different foods will work in combination, so superfoods should be incorporated into a super diet to see the benefits.

What are the current nutritional pin-ups?

The foods getting press at the moment are exotic berries - goji, açai and Chinese wolfberries. Spirulina, an aquatic plant, has hit the headlines for its energy-boosting properties and high protein content. Pomegranates, wheatgrass, quinoa, artichokes and green tea are all vying for top spot in the superfood stakes, and look out next year for seabuckthorn and antioxidant-packed dark chocolates.

So are they all obscure and expensive health foods?

Looking at the list above, the superfood concept might look like a marketing ploy for pricey and exotic products with dubious environmental credentials. However there are many superfoods available that don’t need the hard sell – broccoli, onions, garlic, eggs, olive oil, nuts, watercress, oily fish, beetroots, beans, wholemeal bread, pumpkins, oats, tomatoes, sweet potatoes…

Our top tip is healthy phytochemical compounds also give plants their colour. That means the more vibrant the colour of your fruit and veg, the more prized antioxidants they'll contain.
