ARE Potatoes Healthy? Here’s the ScienceAre Potatoes Healthy? Here’s the Science Potatoes provide fiber plus vitamin C and B. When you cook and cool them, potatoes become loaded with resistant starch. Resistant starch is a carbohydrate that naturally revs up your body’s fat-burning furnace. Like fiber, you can’t digest or absorb resistant starch. Your body ferments it, which triggers it to burn fat instead of carbs.
Despite its accolades, a Harvard study made headlines when scientists found that potatoes (in any form) were linked to weight gain. However, in terms of the health qualities of potatoes, the benefits still seem to outweigh the drawbacks.
(Editor's Note: We need to read that Harvard study before accepting that "potatoes are linked to weight gain" actually means "potatoes cause weight gain". The words, "are linked to" are quite ambiguous and do not mean that potatoes cause weight gain. For example if a person is ingesting 10# of potatoes daily, as well as 14 cheeseburgers, 25 Pepsi's, and 4# of dark chocolate daily, then it might be true that "potatoes are linked to weight gain", because it is highly likely that anyone who eats like that will gain weight. Further, what form of potatoes? Was the Harvard study talking about organic baked potato with a pat of butter? Or was it referring to 7 servings of fast food french fries? For now, I'm taking that Harvard study with a 1/2 grain of salt, and will continue to eat potatoes--lots of them.
Last but not least, the term "resistant starch" is a new concept to this writer.)
