Unlike many low-carb diets that ban potatoes from the menu, a U.S. study says they help you lose weight. How does that work?
Fans of the tasty tuber watch out: According to a new scientific study, potatoes are not as bad for the figure as long assumed. So anyone who has removed them from their menu with a heavy heart can change that again with a clear conscience.
Is potato good for diet?
In the study, which was published in the Journal of the American College of Nutrition, a team of American researchers investigated how a calorie-restricted diet and the glycemic index of foods influence weight. The glycemic index (GI) is a measure of the effect of a carbohydrate-containing food on blood glucose levels.
To find an answer to their question, Dr. Britt Burton-Freeman and her colleagues at the Illinois Institute of Technology took a close look at 90 overweight men and women. They were divided into three dietary groups for the 12-week study: The first group ate a low-calorie diet but was allowed to eat foods with a high GI. The second group also had to reduce its calorie intake and also restrict itself to foods with a low GI, while the third group was allowed to eat as it pleased without any restrictions. Potatoes, however, were on the diet of all participants.
Say goodbye to waist fat – even with potatoes!
- Surprisingly, all subjects from all three groups lost weight – even though there were major differences between them in terms of their weight loss.
- Incidentally, the women and men who followed the third and most relaxed diet plan had also – completely voluntarily – cut back on their calorie consumption.
- The conclusion remains the same: according to the study leader, Dr. Burton-Freeman, it is not worth excluding potatoes from one’s diet. Instead, one should save calories.
Potatoes for diet: it all depends on the preparation
If you want to enjoy the health benefits of the tuber, you should dress it accordingly.
1. Firm cooking varieties are the healthiest thanks to their low GI.
2. Early potatoes can happily be eaten with the skin on, as most of the nutrients are stored directly underneath.
3. All others are better enjoyed peeled, as small amounts of toxins are stored in the peel – and especially in the eyes and green parts – when ripe.
In addition to vitamin C, these tasty potatoes also contain a lot of high-quality protein, potassium, magnesium, copper and numerous fibers. If you want to preserve the high nutrient content, you should cook them in a little water.
