Dr. Robert Lustig's book is Fat Chance: The Bitter Truth About Sugar.
He is a paediatrician, a kids doctor and has many years experience of fat kids in America.
In the 1970s there was John Yudkin's book "Pure, White and Deadly".
Yet it's now far worse than it was then. Almost all cereals are heavily sugared - shredded wheat and porridge are the only ones we can buy naked of sugar.
There is now the danger of corn syrup, FRUCTOSE - just as deadly as sugar.
Rats trained to expect electric shocks if they eat cheesecake will still rush to eat it.
Mammals seek sweetness for energy but in the wild activity burns it off. We don't.
This goes way beyond individual willpower into deeply laid instincts which the food industry is manipulating. They study the "bliss point" at which sugars/ corn syrup produce effects like cocaine in the brain.
In this generation young people are going to die long befiore their parents do because of bad food and cheap booze.
People haven't changed much. Willpower and stupidity is about the same as ever. But the food industry is a lot cleverer at manipulating us. Governments stay silent and take their money. Millions are dying of obesity related diseases, including kids.
Some key advice:
Don't buy fizzy drinks except as a very special treat - elsewhere I've seen this suggested as once a month.
Don't drink bought fruit juice - it has had the fibre removed making it too easy to digest its sugars.
(I know cordials are bad too but I love them so I will try to make them weaker.)
Home made cakes and desserts - use a third less sugar than recommended.
I've also seen recommendations to use a few drops of lemon juice to sharpen the taste. It trains us away from the sweeter taste levels.
