Childhood and sugar are inextricably related. There are very few things a child like more than her sugary treats. Their world lights up with sugar in the form of chocolates, colourful candies, and other sweets.

The World Health Organisation (WHO) in its new guidelines for sugar intake for adults and children have recommended reduced intake of free sugar throughout the life. According to WHO the intake of free sugar should be less than 10% of total energy intake. A further reduction to below 5% of total energy intake will have further benefits, according to them.

As per the American Heart Association (AHA) children below 2 years old should not have any free sugar at all. For children between 2-18 years old, recommended daily intake of sugar is 25 grams (6 teaspoons) or less. A study has found that more than 81% of children in the US eat more sugar than this recommended quantity. This, in turn, often leads to a higher BMI when they become older.
