participation of 15,500 middle-aged people. At the beginning of the experiment, participants completed a detailed questionnaire on nutrition.

There are several explanations for such research results. The authors believe that participants who overeat carbohydrates consumed a large amount of refined carbohydrates. They have no nutritional value and have implications for weight and overall health.

reduced the risk of
premature death, unlike those who replaced carbohydrates with animal proteins and fats.
