Here's what happens inside your body when you eat too much sugar
You might want to think twice before putting an extra spoonfull of sugar in your tea after watching this video.
The team at Tech Insider sat down with a US expert to reveal exactly what the dangers of having too much sugar in your diet can be.
As well as the obvious weight gain, too much of the sweet stuff also opens you up to a range of different diseases as your liver struggles to metabolise the fructose.
We now have the data that shows that when the liver turns what it's being exposed to into liver fat, that is the signal driver of insulin resistance," said Robert Lustig, a Professor of Pediatric Endocrinology at the University of California, San Francisco.
"Ultimately that's what drives this phenomenon called metabolic syndrome.
"That is type II diabetes, hypertension, lipid problems, cardiovascular disease, cancer or dementia."
Scientists have also found that men who consumed more than 67 grams of sugar per day increased their risk of mood disorders by more than a fifth compared with those with an intake of less than 39.5 grams.
Lead researcher Dr Anika Knuppel, from University College London 's Institute of Epidemiology and Health, said: "High sugar diets have a number of influences on our health but our study shows that there might also be a link between sugar and mood disorders, particularly among men.
"There are numerous factors that influence chances for mood disorders, but having a diet high in sugary foods and drinks might be the straw that breaks the camel's back.
