Yet another study is showing low carbohydrate diets, such as the fashionable paleo and keto variety, may be dangerous and could lead to increased risk of dying of heart disease, stroke, and cancer.

A healthy and balanced diet includes foods such as fruits, vegetables, bread, pasta, and potatoes.

Popular weight loss diets, that some may view as beneficial in the short-term, may come with a hefty long-term price tag.

“One thing is sure,” Dr Maciej Banach, professor of medicine at Medical University of Lodz, Poland, told Newsweek: “we should avoid [low carbohydrate diets].”

Banach explained low carbohydrate diets have been regarded as beneficial for our health in the past, but based on his team’s research it is now “clear” that is not true. And even though such regimes aid weight loss, the public should be “very careful” when following very restrictive diets, particularly those that feature no carbohydrates for long periods of time.

What makes low carb diets appear to be so dangerous? Banach pointed to previous studies which have linked animal protein, and red meat and processed meat in particular, to a higher risk of cancer.

“The reduced intake of fiber and fruits and increased intake of animal protein, cholesterol, and saturated fat with these diets may play a role. Differences in minerals, vitamins and phytochemicals might also be involved,” he said.

He concluded: “The findings suggest that low carbohydrate diets are unsafe and should not be recommended.”
