By Owen Jones


Some people have always contended that some fruits, nuts or vegetables are super foods. This is a controversial issue, but it must be the case that some foodstuffs are better for you than others, but whether it is reasonable to hype up a foodstuff for a quick buck is another topic. Blueberries are a case in point. Are blueberries a super fruit or not?

Proponents of blueberries say that they are rich in antioxidants and that they can improve vision and relieve eye strain; enhance brain and memory functions and combat urinary tract infections (UTI's). Blueberries are said to be abounding in antioxidants and anthocyanins, but what are they?

Well, antioxidants are said to counteract the effects of oxidation and free radicals, which are often linked to the development of cancer and anthocyanins are a kind of flavonoids, which are also an anti-carcinogen.

Above 70 is thought to be high; between 56 and 59 is medium and below 55 is low. Blueberries, at 53, is at the high end of low. This is not vital information for many individuals, but it is vital for dieters and diabetics.

Blueberries are thought to improve eyesight because of the anthocyanins, which reinforce the capillaries, which would assist the flow of blood to the eyes, which might help preserve vision. This would improve eye strain or eye tiredness

If this assists preserve vision, it would also delay hair loss, because hair loss is normally associated with a lack of blood/nutrition to the hair follicles which then simply die of starvation, as in male pattern baldness.

Blueberries are a fruit high in flavonoids which are antioxidants as stated above. Some individuals claim that flavonoids can improve the connections between neurons in the brain, which would probably increase mental capacity.

If this is the case, then the consumption of blueberries would also help slow down the advance of lack of motor control: that is, it could help the elderly move more naturally, less inelegantly.

However, the same individuals will admit that to create a 5-6% improvement in motor skills would probably take a daily consumption of about 100 grammes per day, which is naturally not an insignificant amount, even if you like them and cultivate them yourself.

It has also been stated that the daily consumption of blueberries reduces the quantity of LDL in the blood, which is popularly called 'bad cholesterol'.

Fresh blueberries: eat while in season but freeze as much as you can get hold of.

Frozen blueberries: cook in pancakes, muffins and put in home-made ice-cream.
