The Potato: 19 lumps of sugar or superfood?

This appeared in the British media a few days ago:
“The nation’s obesity crisis is partly being fuelled by the seemingly harmless potato.
Scientists have found a single baked spud contains the equivalent of 19 lumps of sugar.”
 
Five years ago, in the same press:
“Ignored by dieters because they are ‘fattening’, few would class the potato as a ‘wonder food’ packed full of vitamins, minerals and nutrients.
But the spud is actually better for the body than traditional superfoods – such as bananas, broccoli, beetroot, nuts and avocado, a study has found.
The researchers said people are wrong to shun it in favour of modern and more expensive alternatives.”
 
No wonder we are all confused about what to eat…
 
So what are the facts?
 
Potatoes are high in fibre (more than five times the amount in a banana), vitamin C (more than in an orange) and Selenium, an important mineral for immune health. There is also some evidence that they may lower blood pressure.
 
However, they have a high glycemic load, which means that the energy in them (carbohydrates) is released quickly, which leads to a spike in insulin. This isn’t great for weight management, as it can set off a roller coaster of sugar and insulin. Eating protein with the potato would minimise this effect.
 
Sweet potatoes have a much lower glycemic load, and are possibly a choice that is easier on the body. Although that isn’t going to help if you really fancy a potato: baked, mashed, boiled or in a salad.
 
A potato is neither going to kill us or rescue our health. It’s just a potato.
