Blueberries

As one of nature’s only blue coloured foods, blueberries are truly unique. In terms of their flavour and nutritional value, these berries also pack a punch. They are commonly used to add a sweet, juicy taste to a variety of desserts, cakes and pastries. As with all fruits, the nutrients of blueberries are at their most beneficial when the fruit is eaten in its raw state.

Blueberries have a natural, soft white coating which is called ‘bloom’. This is part of the fruit’s protective layering – so it is nothing to be worried about. In fact one of the great things about blueberries is that are such an easy fruit to eat – pop them in your mouth whole and enjoy! No peeling, hulling or other preparation is required.

Nutritional facts:

  • Blueberries rank very highly when it comes to antioxidant properties so they contribute towards neutralising ‘free radicals’ that are known to cause cancer, heart disease and other age-related illnesses
  • Studies have found that eating blueberries can improve memory and cognitive function
  • With relatively low GI value, blueberries can help regulate blood sugar levels
  • Antioxidants in blueberries are linked to increased eye and retina health
  • Blueberries contain a compound that assist with urinary tract health and can prevent infection
  • Low in calories and high in potassium
  • High source of vitamin C, E and fibre

Did you know:

  • Blueberries are sometimes called ‘star berries’ because of the shape of the blossom
  • The skins of blueberries can be used to make paint, and the juice is often used to make dye
  • The fruit grows on different plant groups including: ‘highbush’ (cultivated), ‘lowbush’ (wild) and the less common ‘rabbiteye’
  • Native to North America, highbush blueberry cultivation was widespread among Native Americans – who taught the process to European colonists
  • Native Americans valued the medicinal properties of blueberries – the juice was used to treat a range of illnesses
  • Blueberries grow best in climates where summer days are warm but nights are relatively cool
  • Blueberries earned the title ‘Superfruit’ due largely to their very high levels of anti-oxidant properties

Selection and storage

Select blueberries that have a firm, plump appearance and the soft, hazy ‘bloom’ (natural coating). Don’t buy blueberries that are withered or seem excessively soft.

When buying in punnets, it’s a good idea to gently shake the punnet. Blueberries should be loose and move easily. If they don’t it could be a sign that they are mouldy or bruised.

Ideally you should eat blueberries within a few days of purchase. They like to be stored in a cool, dry place. They will last well in the refrigerator for up to 5 days. Don’t wash blueberries before refrigerating (washing removes their protective ‘bloom’). Just give them a quick rinse immediately before eating.
