Potatoes are known as an inexpensive, fat-free and cholesterol-free source of vitamins and fiber. They are just good eats! However too much of a good thing is never a good idea.

According to The Sydney Morning Herald, a new study has shown that potatoes might contribute to weight gain, and not just when they're in the form of potato chips and French fries.

Researchers at the Harvard School of Public Health found that ordinary potatoes, even eaten in moderation, might be fattening.

"The starch in potatoes is the problem," said lead researcher Dariush Mozaffarian. "Overall, physiologically, potatoes, refined grains and sugars are all likely equally detrimental for weight gain. In other words, calorie for calorie, there is little difference between eating a potato, cornflakes, white bread or a bowl of table sugar."
