A new study suggests that a popular diet may increase the risk of heart disease, with some reports indicating a 67% higher risk of heart attack and stroke, while others mention a 135% increased risk of heart disease death. However, the specific diet in question is not consistently identified across reports, with some mentioning ultra-processed foods, intermittent fasting, and time-restricted eating. The relationship between different diets and heart disease risk appears to be a subject of ongoing study and debate.
