What is considered on par with cigarette smoking as a common cause of death?

A poor diet is recognized as a significant risk factor for various chronic diseases, including heart disease, diabetes, and certain cancers. Research has increasingly shown that dietary patterns can have a profound long-term impact on health, much like cigarette smoking, which is linked to a host of serious health issues including lung cancer and cardiovascular disease. Studies have indicated that the prevalence of diet-related conditions and their mortality rates can rival those associated with smoking, making poor dietary habits a leading cause of preventable death.

In contrast, while lack of exercise, excessive alcohol consumption, and drug overdose are indeed serious health risks, current data links poor diet more directly and equivalently to mortality rates in the broader population. This relationship underscores the importance of holistic nutrition and lifestyle choices in disease prevention and health promotion.
