It can be hard to imagine a life without sugar – it’s in a lot of the foods we eat. But how much sugar is too much? The American Heart Association recommends that women eat no more than six tablespoons a day; men should eat no more than nine. This is equivalent to 25-36 grams or about 100-150 calories a day of sugar. Meanwhile, the World Health Organization (WHO) recommends eating a maximum of 50 grams, but preferably no more than 25 grams of sugar per day.
