Mollie thanks for posting this, I'm in complete agreement with you.
I'm convinced that added sugar does more harm from a public health point of view, and an individual point of view, than alcohol.
Durhamjen the reason fructose within whole fruits is not harmful is that it is contained within the cells of the fruit, and is not broken down in the stomach and small intestine, unlike fruit juices which are very quickly absorbed. Fructose, unlike other sugars, is also converted into fat and stored in the liver.
Someone asked about the RDA - it's 90grams per day, or about 3 tablespoons.
From a personal point of view, I've tried to eradicate added sugar as much as possible, but I still consume about 30 grams/day from fruit and milk, which contains lactose.
The benefits are that I've lost over a stone in weight, without trying to reduce my intake of fats (I love butter and olive oil), but most importantly a lot if the pain I was getting in various joints has completely gone.
