A study clarified the “good and bad carbohydrates” debate, which creates confusion among people about their consumption.
A new study published in Frontiers in Nutrition reveals which good and bad carbohydrates can be chosen, which is often a challenge for people who pay attention to their nutrition or have to go on a diet.
USAKeith Ayoob, the head of the research conducted at the Albert Einstein College of Medicine in , said, “There is a reason why these foods are classified into different food groups; Most importantly, they tend to have very different vitamin and mineral contents.” said.
The study found that replacing starchy vegetables, such as potatoes, with grain-based foods, such as rice and whole-grain bread, for just one day led to a 21% decrease in potassium, a 17% decrease in vitamin B6, an 11% decrease in vitamin C and a 10% decrease in fiber levels.
Compared to starchy vegetables, grains tend to be lower in potassium and vitamin C, but provide higher amounts of thiamine, zinc and vitamin E, the findings noted.
“Many starchy vegetables are good sources of potassium,” says Ayoob. “Eating grains instead of starchy vegetables may further widen the gap between recommended and actual potassium intakes.”
“There was also a significant reduction (-10%) in fiber intake when potatoes were replaced by grains. “This finding reinforces the need to include both starchy vegetables and grains in the diet.” said.
