Boeiende documentaire (uit de serie the truth about...)

Deze aflevering:
As a nation, we love eating carbs, and they are right at the heart of our diet. The problem is that with 63 per cent of UK adults now considered overweight or obese, many experts think that we are eating far too many wrong sorts of carbohydrate.

Xand van Tulleken is a medical doctor and self-professed lover of carbs, to the point where he used to weigh 19 stone. He is keen to discover whether they really are a killer as claimed by many, responsible for record levels of obesity and type 2 diabetes. The film investigates cutting-edge research into the possible link between carb consumption and infertility in both women and men, and looks into whether genetic changes are taking place as we pass our eating habits on to our children.

Xand and a team of volunteers play 'blood sugar bingo' as they attempt to guess how much sugar a selection of common foods each releases into the bloodstream. Xand discovers that looks can be deceiving - a baked potato is the equivalent of a staggering 19 sugar lumps, whereas a large bowl of strawberries is only four. There is also a simple test that anyone can do at home to determine how well they tolerate starchy carbs like rice, pasta and bread. Simply chew a small, unsalted cracker and time how long it takes to change taste in the mouth.
