A popular diet has been found to raise the risk of heart disease, with some studies suggesting certain food additives and preservatives may be linked to increased cardiovascular risk. However, the specific diet or foods in question are not consistently identified, with some reports mentioning low-carb diets, ultraprocessed foods, and food additives, while others discuss the potential impact of intermittent fasting or lean beef consumption. The relationship between diet and heart disease risk appears to be an area of ongoing research and debate.
