Today we made our weekly shopping in Beytan supermarket. As usual, I tried out all the fruits but the grapes were so sweet that I passed and tried the carambola (left). It used to be an acidic fibrous tasteless thing, bought for its highly decorative star body, but this was a very sweet meaty fruit. Cultivated fruits have been genetically modified to be much higher in sugar content than their natural, ancestral fruits. There goes the standard dietitian advice of eating MORE fruit because fruit is linked to reducing risks of heart disease, cancer and stroke. Another bad diet advice.
But the fruit-based diet of some animals at Melbourne Zoo is posing problems for their health. Dr Senaka Ranadheera, a food scientist at the University of Melbourne said that sugar levels in some fruit, like plums, have doubled, although are still much less than those in soft drinks.
