Hidden sugar in foods is difficult to quantify - I have been an avid food label reader for almost 50 years now. In the last 30 years, food manufacturers have almost doubled the amount of sugar in food. Check out the sugar in low-fat products against the normal product to see how much more sugar is present. Fizzy drinks, smoothies and fruit juices can have almost your entire daily allowance of sugar in one portion.
Let's hear it for plain water to drink, unprocessed foods to eat and reduce the number of sweet treats. This is not a restricted diet - there are so many delicious things to eat with natural sugars and healthy fats.
In 1972, John Yudkin wrote Pure, White and Deadly about the dangers of sugar. He was villified by the various sugar lobbies and his career ruined. The power of the multi-nationals is scary. Look how long the link between cigarettes and lung cancer was concealed by the tobacco companies.
Tooth decay, obesity, mood swings, diabetes, heart disease - who knows what else - all seem to have links to a diet high in refined sugars.
However, I am delighted to say there is less than a teaspoon of sugar in a glass of red wine.
